Expandable Universal Audio Processor
Designed for Commercial applications, the UAPG2 is the new DSP expandable universal audio processor for medium paging and multi-zone audio routing applications. With its powerful audio digital signal processing, the UAPG2 can easily be used in a demanding environment for high audio quality. Using the Ethernet port, it is easy to connect and control the UAPG2 through an IP network or direct from a PC.
Sound quality
The advanced 24 bit A/D and D/A converters, together with the 48/96 kHz capable audio processing and the ADSP 21371 DSP (266 MHz SIMD SHARC Core, capable of 1596 MFLOPS peak performance), guarantee an excellent sound quality with the lowest possible latency.
Easy to use PC software for system design and control (GUI)
The UAPG2 System software provides all the necessary tools to set up and control the hardware and software elements of the UAPG2.
Impressive library of signal processing tools
The UAPG2 is a comprehensive system which integrates pre-amplifier, compressor-limiter and equalizer, as well as
matrix and delay functions into one unit. Useful features like Automatic Gain Control, Feedback killers, Automatic Microphone mixers and Crossovers, Automatic Noise sensing, are also part of the UAPG2 DSP component  library. Internal processing of audio signals can be fully programmed to suit the client’s application. Installers can select the audio processing feature(s) that they wish to apply to the various inputs and outputs from a library on their PC, using software provided with the UAPG2.
Once the configuration process is completed, it can be loaded into the UAPG2. All configurations can be backed-up onto PC and loaded into the UAPG2 as and when required.
Advanced Preset manager
The UAPG2 includes two types of presets:
More than 16 Parameter presets: They enable values of multiple parameters of the same design, such as levels, gains, EQ, etc. to be restored either from the PC software, the remote controllers or the control inputs.
UP to 32 Design presets: they enable completely different designs to be restored. Application examples for this feature are hotel meeting rooms with removable walls.
Message player
The Message player incorporated into the UAPG2 allows you to play any kind of message to be played.  Only one message per UAPG2 can be run at a time. With the 100 Mbyte memory, the following storage times are available with WAV format: 
- 36 minutes of audio message at 48 kHz,  8 bits
- 18 minutes of audio message at 48 kHz, 16 bits
Scheduler and event management
The scheduler allows planning of events (preset change, message play, close/open TTL out or change component’s adjustments). Up to 128 different schedules can be scheduled. In one schedule you can define up to 100 events.
Control inputs
The UAPG2 has 16 (0 to 5 VDC) control inputs either analogue or Logical (TTL). Each control can be associated to any of the variable audio processing functions of the UAPG2 (input level, output level, equalization, routing, mute, bypass, preset change…). Several parameters (Min + Max values, positive or negative variation, linear, log, anti-log) can be programmed for each of these controls.
8 Logic outputs (GPIOs)
Each UAPG2 is equipped with 8 logic outputs (common rail contact). Each of those hardware outputs can be associated to virtually any software buttons or LEDs the system designer requires. The logic outputs can be used to enable the UAPG2 to control external equipment.
RS-232 serial interfacing for third party control
The UAPG2 can be controlled from third party equipment like Vity, AMX or AMX, Creston or Vity room controller via its RS232 serial port via its RS232 serial port, or IP network.
Ethernet port
The UAPG2 can be programmed, controlled and also monitored via IP network using its RJ45 connector.
Junction Box
Easy chain-connection of UAPG2 peripherals (URC and PPM WJB-V3), using standard CAT5 cables. Junction box is included with the PPMWJB-V3.
UAPG2 Digital Link
If more inputs or outputs are required, it is possible to digitally link up to 12 UAPG2 (maximum distance between two UAPG2 is 10 meters). Through this link, you can share up to 16 channels at 48 kHz or 5 channels at 96 kHz sampling rate to the next device.
