AudioPressBoxAPB-400 R-RPS

Rack design input module with 4 routable Inputs (A, A+B, B), 4 buffered outputs for APB expanders, Redundant Power Supply

A professional active press box drive unit (Audio Splitter) serving as a drive unit for AudioPressBox expanders.
It features 4 MIC/Line Inputs (A,A+B,B) 
What is more, it can also be used for bilingual conferences as it features 2 separate channels A and B.
Each input can be routed to channel A or channel B or both at the same time.
It  serves as a drive unit because it has 4 buffered expander Outputs (2x A and 2x B) and can power additional 96 Line/MIC Outputs. 
So with this unit you can route route 4 individual inputs to up to 96 Line/MIC Outputs! 
You can connect any of our expanders to it. 

The RPS unit does also have a Redundant Power Supply.

Drive unit for : APB-008 SB-EX, APB-008 IW-EX, APB-008 OW-EX, APB-008 FB-EX, APB-024 R-EX, APB-P008 OW-EX, APB-P008 IW-EX

+48V +48V If you are about to use condenser microphone, turn Phantom power switch ON to feed your microphone with 24/48V. If you use dynamic microphone or microphone with his own power, you can switch this OFF.
PAD PAD If you are using microphone as an input, this button should be set to “Off” position. If you are using input from the mixing console or CD player, please set this switch to “On” position.
BUS Routing switch Each microphone could be routed to 2 separated groups or to both groups at the same time. This is useful, if you have two (or four) lecterns and you want to route signal from each microphone (or group of 2 microphones) to separated tracks. Reporters can edit the recording easily, if they have both lecterns on separated tracks. You can label the outputs in the output extender with names of the lecterns or groups and reporters easily decide which group output they want to use.
AFL AFL For better check your levels, you can isolate output from each group to your headphones. You can check the output levels of each group by hearing. Just push the button and you will hear output from particular group.
PFL PFL To check your levels only for one input, push this button and you can see the level of output for corresponding input. You can easily see if all microphones have the good output levels and identify, if some of the microphones are too loud or too silent in the output.
COMP COMP (Compressor/Limiter operation button) To provide perfect output signal without clipping or distortion, you can switch the Comp button ON. If you switch this OFF, signal in output could contain signal clipping or distortion.
HPF HPF (High Pass Filter) This button helps to avoid distributing low-end rumble like a microphone handling noise or pops. You have 2 options – full range or 160Hz low-cut frequency. The one you choose depends on the sound, you want to filter out.
OSC OSC (Oscillator operation switch) To test signal level, which is coming to the outputs, you can switch this Test 1kHz sine signal oscillator on. After recipients set the levels in their recording devices, you should switch this function OFF. When compressor switch is set to ON, output signal level won’t exceed this maximum output level.
