Technomad will introduce Schedulon v3.0 at the ISE show, delivering new features and enhancements including a nearly 200 percent increase in data transfer speeds, while retaining its flexible options for instant and automatic playback of user-loaded audio files.
Technomad LLC, a leader in advanced loudspeakers and audio systems since 1995, announces that Simi Valley Hospital, one of 17 hospitals operated by Adventist Health in the western United States, is using two Technomad Schedulon automatic MP3 players for scheduled and on-demand playback of audio files in multiple locations of the hospital.
Located in Simi Valley, California, Simi Valley Hospital is a 201-bed acute care facility featuring the Nancy Reagan Breast Center, emergency services, state-of-the-art diagnostic imaging, pediatric rehabilitation, ICU/Telemetry, a Level II NICU and impatient and outpatient surgery among other medical services. The Schedulon provides dual-functionality for the hospital, essentially acting as two devices in a single 1RU system: a sophisticated, networked, scheduled-audio player that plays sounds on a user-defined schedule; and a simple, on-demand audio file player that acts as a rugged, rackmount iPod with sounds ‘hard-assigned’ to knob positions for quick-predictable access.
At Simi Valley Hospital, both units are used to deliver music and announcements to various locations at specific times, including the main entrance. The systems provide an easy-to-manage user interface for uploading and scheduling files, eliminating the need for Simi Valley telecom and IT staff to fumble with CDs and traditional playback systems.
“The Schedulon provides a digital device that is simple to operate without mechanical parts, making it reliable and leaving little possibility for system failures,” said Greg Eslinger, Telecom Department Manager for Simi Valley Hospital and Adventist Health. “The ease of building a schedule and playing files on-demand are standout features, and its automated features reliably play audio as scheduled.”
Eslinger uses one Schedulon to play soft music at the main entrance from 7 a.m. until 8 p.m. The Schedulon plays a seven-minute loop of instrumental music to instill a soothing effect and de-stress visitors and patients as they enter the hospital.
The second system delivers music and announcements including information on visiting hours and daily prayers from the hospital chaplain to the Main Campus, North and South Patient Care Towers, North Campus plus other buildings. Simi Valley Hospital licenses music such as “Turn, Turn, Turn” by The Byrds which plays every two hours at normal volume from 8 a.m. to 8 p.m. and softly from 10 p.m. to 6 a.m. to signal nurses and patient care staff to reposition bed-confined patients to help reduce pressure ulcers.
In addition to ripping files from CDs, Eslinger has added a professional microphone and recording system that is currently used to record the chaplain’s prayers directly into the Schedulon. He expects to also use this in the future to record security and emergency-related announcements in addition to other messages.
“The Schedulon has a front push-and-turn knob that we currently use mostly for testing purposes but I expect will be used for on-demand playback of messages in the future,” said Eslinger. “We have four-shifts of telecom operators, and the goal is that they could trigger specific messages based on Codes they receive. We will also take better advantage of password protection and other user safeguards when we begin using the on-demand functions more regularly.”
Eslinger currently has the Schedulons installed in secured network areas where the IT staff can gain immediate access. The compact size also allows for simple front desk installation, where support staff can access the Schedulon’s on-demand features in response to emergencies and special events, while the unit continues to play sounds on a schedule with no user interaction.
Eslinger adds that his overhead paging system and primary Schedulon is plugged into a 40kW UPS in the Technology Services Center which is backed up by two-1MW diesel power generators giving 100% power reliability; and the main entrance Schedulon is plugged into ePower.
Based on Technomad’s unique military technology, the Schedulon provides instant playback of up to 99 knob-assigned, user-loaded audio files from a front-panel screen, and allows automatic playback on a user-defined schedule based on an internal clock or synchronized network time server. Scheduling can be as straightforward or complex as desired, down to the exact time of day. Operators can interrupt automatic messages and play a knob-assigned siren or emergency announcement from an internal sound library in critical situations.
Operators can also use the Schedulon to record field audio for instant or future playback via the user-defined schedule. All recording, uploading and scheduling tasks can be achieved without the need for a computer or web browser to minimize the risk of crashes and viruses. The company recently announced a new internal power backup option that provides a battery for up to 20 minutes of audio depending on quality; and keeps scheduled events on target for approximately 75 minutes.

We must thank the consumer electronics (PCs included) people who have developed cost-effective technologies that us pro audio folks can benefit from. Case in point is the advent of portable digital audio players (MP3 players). In the pro audio world, there is a number of manufactures that have developed and bring to market cost-effective digital or solid state audio recorders/players which have gained acceptance in many applications for field recording broadcast, sound reinforcement, and public address systems. It is not unusual now to hear these devices in use in many public spaces such as department stores, where a customer can press a call button on a pillar, which triggers a pre-produced announcement over the PA system alerting staff that “a customer requires service in the sports department,” or an announcement at the airport reminding us that the airport is a non- smoking environment.
There are many environments where a message has to be communicated to the masses either by immediate command through the push of a button, or triggered by a third-party control or by some internal scheduler. There is a number of fruitful choices from a number of manufacturers (TOA, Nel-Tech Labs, Raicom, TASCAM, Stop & Listen, etc.) that have developed products for common commercial audio applications. A recent addition to this arena of digital audio players is the Schedulon from Technomad (check out http://www.technomad. com). Yes, the folks who bring us military/ weatherproof-grade loudspeakers.
The Schedulon is a rackmount (1U) MP3 player/recorder with a built-in scheduler. With the use of a web browser or by navigating via a front panel knob and display, the Schedulon offers the ability to upload audio files, schedule playback of audio files, and automate playback of audio files. The unit utilizes flash-RAM memory, which makes this unit more dependable than a PC-based solution. Although the unit has an onboard clock, audio files can also be triggered by an external clock server.
The Schedulon can record audio from its stereo line-in jacks Â audio is encoded as high-quality (192 kbps) MP3 sound files and assigned to any desired knob location for playback. The better option is to upload the audio file using the browser application or to upload files to Schedulon’s USB memory drive from your computer.
The applications for the Schedulon and many similar units are numerous: repeat messaging at airports, department stores, malls, training facility scheduling (schools, airports, hospitals), corporate audio (no CDs to misplace), training, sports facilities (load team music or special effects for instant playback), automatic safety announcements, theme park audio, sound effects, pool-side music or DJ applications, and much more. Upon evaluation, it did not take much time to connect the unit and navigate through the browser.
Once connected and logged to the unit, you will discover six tabs (Status, Settings, Control, MP3 Upload, Knob Set, Scheduler) allowing you to view and enter values via drop-down selection. All but the Status tabs permit entering and adjustments to the unit. Without the use of a computer, you can navigate through the functions with the front knob and display, but this makes it taxing.
Different play modes can be assigned to each knob position: play forever/unit stopped by user (for sirens); play once, then stop automatically (for songs like the national anthem); and play while button held in (for sound effects). The fact that each knob position can store a different audio file AND play behavior is unique in the marketplace, I believe. The evaluation unit had 50 or so preloaded audio files, most of which, to no surprise, had military applications. One surprise that happened when I logged on was that the unit announced its IP address, which could inadvertently be announced over the PA system for all to hear.
Generally, the unit worked to expectation, and can be recommended for applications as previously noted.
The unit we evaluated did not offer any contact closure or RS232 port for interconnectivity to other control systems. The audio outputs are unbalanced (not-so-pro audio), and the device’s “current time” is found at the Status tab; however, the current time should also be at the Scheduler tab for ease of reference during programming. Additionally, the unit data port is found in the front panel, something I would not expect if this unit is to be driven by external IP-based timer or clock. Projects or systems requiring additional features may not find this unit appropriate, but overall, the Schedulon is a good performer and is basic in operation and functionality.

The announcement of IP address can be turned off as an option. The unit can have sounds triggered by CGI commands via Ethernet/LAN, and the unit can automatically synch itself to an external time server
These are two different things. Both use the network. The time-server synch is critical if you need things to happen exactly on time, for years at a time. The Data Port (Ethernet port) can be located on the rear if requested at time of order. – Technomad LLP

Solid scheduling-enabled audio player and recorder that fits the simplicity bill.
By John McJunkin
Technomad, manufacturer of military-oriented audio equipment (particularly PA systems) has introduced its Schedulon scheduling-enabled audio player/recorder. This device is nearly identical to Technomad’s SuperConductor, which is the purely military version of the device. As a manufacturer of military-grade technology, Technomad is known to make its products figuratively bulletproof, and the Schedulon was developed with this notion in mind. It records to and plays back from RAM, so there are no moving hard-disk parts to cause problems. It’s distinguished from similar computer-based solutions by the fact that it is a standalone device, immune to viruses or operating system crashes or hang-ups. I’ve always been a great believer in over-engineering, which helps avoid embarrassment and, more importantly, the potential loss of clients that can be caused by equipment failures. The Schedulon very much appeals to my sensibilities in this regard.
The military recognizes that much of its equipment is destined to be operated by 18-year-olds who have little experience with technology, so simplicity is the key word. The Schedulon’s 1RU front and rear panels very clearly fit that bill. There are just five features on the front panel: From left to right, there’s an LCD display, a data-input knob, a removable thumb-drive access panel, an RJ-45 Ethernet port, and a large bat-handle power switch. The LCD displays 32 characters on two lines, and it is very reminiscent of the old-school Yamaha processors and synthesizers. The data-entry knob is of the large variety colloquially described as “chicken-head”; it spins continuously for data input and can also be depressed as a pushbutton switch. It doesn’t get much simpler than a single knob and a basic LCD display for control and feedback.
The rear panel is also simple. From left to right, you’ll find a fuse holder, the unit’s integrated AC power cord, a Neutrik 1/4in. TRS output jack, a second RJ-45 Ethernet port, and two stereo RCA pairs representing audio in and rec in. Again, the Schedulon sports a very straightforward, no-nonsense design, which is right in line with the requirements you’d expect from the military.
The Schedulon is essentially designed to do one thing: automatically play audio at prescheduled times or immediately under human control if desired. There are obviously numerous applications for such a device. In an educational setting, specifically a school, the Schedulon can be used to play tones or recorded speech intended to alert students that class begins in 10 minutes, again 5 minutes later, and then a final alert 1 minute prior to the start of each class hour. The minimum time resolution of the scheduling is 1 minute, so countdowns that update every minute are possible. Additionally, emergency messages can be delivered, alerting students of a fire or other dangers. For numerous applications, the ability to play hourly chimes to indicate the time is nice, particularly since a specific number of chime strokes can be played or even a pleasant voice can announce that it’s 10 o’clock, for example. Up to 100 scheduled playback events can be programmed into the system. In military settings, the device can be used to play Reveille in the morning, Taps at dusk, and other military-oriented sounds. As a matter of fact, the device ships from Technomad with quite a number of military sounds, including alarm sirens and bugle calls. Among other applications, the Schedulon would also be useful in subways, airports, hospitals, or other public buildings, even to provide BGM. For that matter, this system would be useful for any application in which you would otherwise use a flash-drive-based recording/playback system.
In addition to scheduled automatic playback, immediate manual playback is easily accomplished by the Schedulon, which would be useful in the case of an emergency or other situation that necessitates immediate, spontaneous playback of certain messages or alerts. The unit allows a maximum of 99 slots for audio. The maximum length of the audio is determined by the size of the removable flash thumb drive. The unit ships from the factory with a 1GB drive, but larger drives can be installed. The unit compresses audio into .mp3 files, with resolution ranging from 32kbps to 320kbps. Audio is recorded by the unit at 192kbps, which is difficult to distinguish from CD quality by most listeners without the benefit of an A-B comparison. At the nominally standard rate of 128kbps, hundreds of songs could be stored on a system with a 1GB thumb drive. Technomad says that a future version of the system will support the recording and playback of uncompressed 16-bit/44.1kHz WAV audio. The unit’s thumb drive is upgraded very easily by removing the front access panel, pulling the original drive out, and replacing it with the new one. Also, all system parameters, scheduling, and audio are stored on the thumb drive, so it can be transferred into another Schedulon unit — in effect cloning the original.
In line with the military aversion to computer viruses, complete control of all system parameters can be accomplished from the front panel, but computer control via Ethernet is indeed an option; this is the only way that externally recorded .mp3 files can be introduced to the Schedulon. It’s possible that the system would be loaded with all desired audio files and then installed with the intention of only front-panel control. On the other hand, since the system can be controlled remotely via IP, it is beneficial to maintain a network connection — particularly if you’re practicing good network security. Password protection prevents a malicious user from making changes, both from the front panel and via the network. Another major benefit to maintaining a network connection to the unit is that it can connect to a time server, keeping its internal clock precisely correct at all times. On a related note, the Schedulon has an optional backup battery available, which is again in line with the military notion of ongoing technology performance regardless of external circumstances. I discovered this battery feature when I jokingly flipped on the power switch before the unit was plugged in. Imagine my surprise when it fired up.
Among other advantages over similar audio-streaming-over-IP solutions is a network interruption that will not halt playback of critical audio from the Schedulon, since all the audio is stored internally. Additionally, IP bandwidth is not expended by audio streaming. I was prepared to announce that my only criticism of the unit was the somewhat unorthodox 1/4in. TRS audio output. I would normally expect Euro-style or barrier strips or a stereo pair of 1/4in. TRS jacks. As it transpires, however, I was shipped a beta unit. The production version will actually have stereo RCA pairs for input and output, which is a little more orthodox.
In spite of these minor inconveniences, this unit is very solid and would be a great choice for any application in which good-quality scheduled audio playback is necessary. I’d recommend taking a look at it.

Military technology adapted for commercial markets ideal for message repeating in airport and transportation centers
Technomad Associates, LLC, a leader in weatherproof loudspeakers and audio systems since 1995, introduces the Schedulon™, a new automatic mp3 player and recording system designed for integration into commercial security systems for airports and transportation centers of any size.Unique to the commercial market for its flexible scheduling and recording features, the Schedulon is a sibling of Technomad’s popular SuperConductor™ player/recorder used in military and homeland security applications.
The Schedulon provides instant playback of up to 99 knob-assigned, user-loaded audio files from a front-panel screen, and allows automatic playback on a user-defined schedule based on an internal clock or synchronized network time server.Operators can interrupt automatic messages and play a knob-assigned siren or emergency announcement from an internal sound library in critical situations.The Schedulon is a reliable, standalone system with few moving parts and Flash RAM storage, and no computer is required for automatic playback.A hardware-based embedded system, the Schedulon does not use Windows or Linux “under the hood” and is therefore not susceptible to typical PC security risks.
The Schedulon can function as the audio source for a single PA system (in the same way a CD player or iPod can), or it can be used to feed audio to large scale paging / BGM systems in airports or transportation centers.The unit can integrate with a single set of loudspeakers for indoor/outdoor playback of voice, sound effects and background music to a concentrated area, including a specific airport terminal or underground train or subway tunnel; or within a networked PA system to cover entire airports or ground transportation centers.
Scheduling can be as straightforward or complex as desired, down to the exact time of day.Airports and transportation centers can connect the Schedulon to existing facility paging systems to broadcast automatic announcements.Operators can also use the Schedulon to record new announcements for instant or future playback via the user-defined schedule.All recording and uploading tasks can also be achieved without the need for a computer or web browser to minimize the risk of crashes and viruses.
“The Schedulon gives operators the freedom to flexibly schedule and record sounds that match the environs of the venue or installation site,” said Rodger von Kries, vice president of Technomad.“For commercial security, the Schedulon can interface with audio distribution equipment to trigger alarms and pre-recorded emergency messages over PA loudspeakers, serving as a powerful message repeater and campus-wide alert system.Although manual operation is a benefit for instant playback of audio, the scheduling feature ensures that operators are not tied down to monitoring the playback operation.”
The Schedulon offers a feature set that makes life easy for the operator.The Local Configuration Mode feature set provides front-panel access to all functions, as well as password protection and management of audio files without the assistance of a computer.Or, an easy-to-use web interface allows rapid configuration of Schedulon functions via any standard browser.
Remote control capabilities allow operation of the system from a distance via CGI command, and the Lockout feature ensures that only scheduled or remotely-triggered files can be played when the unit is unsupervised.Users can upload sounds and modify the schedule remotely via web browser as well, greatly simplifying maintenance.
The Schedulon is ideal for critical applications — because audio is generated locally by the unit (not streamed over a network), network interruptions will not stop critical sound playback, and network bandwidth is not consumed by streaming audio.Permitted staff can remotely or locally interrupt scheduled playback to play important messages or sound effects as needed.The unit’s internal clock keeps scheduled audio on track even when network time servers aren’t available.
The Schedulon can be purchased separately or as part of a Technomad Turnkey PA system, a full range of complete, pre-integrated, fixed or mobile audio solutions featuring Technomad weatherproof loudspeakers, cables, mounting brackets, a dynamic microphone with cable, and a 6RU rack enclosure featuring a two-channel amplifier and a six-channel mixer.Additional rack space allows for inclusion of the Schedulon and other equipment such as power conditioners and limiter/compressors.
