Portable AudioPressBox case bundle, 1 Line Input, 32 Line/MIC Outputs (4x 8 Line/MIC Outputs)


A professional portable active press box bundle consisting of a AudioPressBox drive unit and AudioPressBox portable expanders.
It features 1 Line Input and 32 Line/Mic Outputs. 
Each Output is independet transformer balanced and isolated.
The drive unit has 2 buffered expander Outputs and can power up to 48 Line/MIC Outputs. 
You can connect any of our expanders to the drive unit not only the ones in the case. 
All of this is placed in a waterproof, heavy duty nanuk case.
The biggest advantage of this bundle is that you can daisy chain the portable expanders in 2 directions. The total length of the cable in each direction can go up to 500m so you can easily cover any type or shapre of a conference room.

Professional portable AudioPressBox bundle includes:

1x APB-D100 drive unit:

  • 1 balanced LINE Input 
  • Switchable High-Pass filter 
  • Switchable Compressor and Limiter for Input channel 
  • 2 separately buffered Outputs

Pack includes 4 AudioPressBox expanders with 8-outputs each. 

4x APB-008 SB-EX expanders:

  • 1 balanced Input for APB drive unit with link Output for another unit
  • 8 High quality balanced Outputs, independent transformer isolated and switchable LINE or MIC Output level.

1x Professional waterproof, special heavy duty case



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.
