Data Sheet

The Digital Audio Platform shall be available with up to 16
inputs and outputs. Inputs/outputs shall be specified in blocks
of 4, up to a total of 16. MIC/Line Input and line level output
options shall be available. Inputs/outputs shall be analog, with
internal 24 bit A/D & D/A converters operating at a selectable
sample rate of 48 kHz or 96 kHz. All internal processing shall
be digital (DSP). Electronically balanced inputs and outputs
shall be provided on plug-in barrier strip connectors. Inputs
shall be individually programmable for either microphone or
line-level audio signal and have assignable 48V Phantom
Power. System shall be expandable to up to 12 total DSP
units via RJ-45 Digital Links using standard CAT-5 data
cabling, up to 32 feet between any two units max. Digital
expansion links shall share up to 16 channels of digital audio
at 48 kHz or 5 channels of digital audio at 96 kHz sampling
rate between multiple units.
Internal system software shall be true drag-and-drop configu-
ration with separate control/monitor GUI via direct data con-
nection or via LAN/WAN using web browser TCP/IP protocol.
Available system audio program components shall include
(but not be limited to) various forms of: mixers, equalizers,
filters, crossovers, dynamics/gain controls, feedback con-
troller, routers, delays, remote controls, meters, noise/tone
generators, and diagnostics. Ethernet communications shall
be utilized for local or remote software control, configuration,
and DSP distribution. After initial programming, systems may
be controlled/monitored using either TCP/IP or RS-232 serial
communication by third-party control systems (such as AMX®
and Crestron®), by PC computer, and/or by dedicated remote
control devices. Software shall operate on a PC computer
running Windows® XP Professional/Vista/Windows 7.
DSP shall include two types of presets - “Master” and “Sub-
Preset”. There shall be a minimum of 32 Master Presets,
which will allow user to switch the unit between totally differ-
ent preprogrammed designs. There shall also be a minimum
of 16 Sub-Presets that allow user to switch to preprogrammed
parameter settings within each Master Preset.
The DSP shall incorporate an audio message player that can
store up to 53 minutes of 8-bit audio or 18 minutes of 16-bit
audio. Audio messages can be played either manually via
direct PC selection, external analog or TTL logic input,
microphone paging station programmable flex button, or auto-
matically via internal event scheduler. Messages can be
manually or automatically routed to any single or multiple
zones/outputs. There shall be up to 128 schedules with up to
100 programmable scheduled events per schedule.
The DSP unit shall incorporate 16 logic inputs to trigger
events or presets and other logic functions and 8 logic
outputs with a common rail contact for controlling external
functions. The unit shall also be equipped with 8 front panel
control knobs, which shall be totally programmable for any
variable function in the design program. This function knob
shall also be 100% scalable to limit amount of volume/
control. Front panel shall also have multi-color LED for
displaying input/output signal presence, routing, and clipping
indication for each input and output.
DSP shall contain both TTL Logic and RS-485 serial control
ports for communicating with a myriad of intelligent remote
controls and microphone paging stations. Remote Intelligent
controls shall be either selector switch with volume knob in a
5-position or 8-position style (RAC 5 or RAC 8), or an LCD
window style with control wheel and selector buttons - (URC
for monochrome RS-485) or (URC-200 for multi-color
IP-based controller). There shall also be the capability for
remote intelligent gooseneck paging stations which incorpo-
rate either programmable flex buttons with expansion button
units, or touchscreen controllers. Multiple remote serial con-
trol devices can also be daisy-chained by installing optional
PPM-WJB junction box.
The DSP unit shall be 1RU high, 17-1/8” x 1-3/4” x 11-5/8”
(W x H x D). Product weight shall be 8 lb. DSP unit shall be
factory warrantied for 5 years.
