Skrzynka Dziennikarska AudioPressBox APB-448 SB

 

A professional portable active press box (Audio Splitter) suitable for both indoor and outdoor press conferences.
It features 4 MIC/Line Inputs (A,A+B,B) and 48 Line/Mic Outputs.
Each Output is independet transformer balanced and isolated.
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.
There is a bus A with 24 Line/MIC outputs and bus B with 24 Line/MIC outputs.
The APB-448 SB also includes a rechargable AccuPack so it can run on its own up to 8 hours.
It also serves as a drive unit because it has 4 buffered expander Outputs and can power additional 96 Line/MIC Outputs.
You can connect any of our expanders to it.
So with this unit you can route route 4 individual inputs to up to 144 Line/MIC Outputs! 

 

 

  • 4 MIC (phantom power) / LINE Inputs – balanced with gain control and 26dB PAD
  • Each Input is routable to A/(A+B)/B Outputs Group
  • 48 High quality independent transformer balanced and isolated outputs
  • Each Output is switchable between MIC or LINE level
  • 2 internal Output Groups: 24x Output A and 24x Output B
  • 2 separate buffered A and B Outputs for driving up to 48 channels of passive
    extenders: APB-024 R-EX, APB-008 IW/OW, APB 008FB, APB P008 IW/OW or
