Skrzynka Dziennikarska AudioPressBox APB-416 C


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 16 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 8 Line/MIC outputs and bus B with 8 Line/MIC outputs.
The APB-416 C also includes a rechargable AccuPack so it can run on its own up to 10 hours.
All of this placed in a waterproof, heavy duty Nanuk case.



  • 4 MIC (phantom power) / LINE Inputs – balanced with gain control and 26dB PAD
  • Each Input is routable to A/(A+B)/B Outputs Group
  • 16 High quality independent transformer balanced and isolated outputs
  • Each Outputs is switchable between MIC or LINE level
  • 2 internal Output Groups: 8x Output A and 8x Output B
  • Switchable High-Pass filter for each Input channels
  • Switchable Compressor and Limiter for each Input channel
  • PFL/AFL for each Input/Output channels
  • Constant level Test signal oscillator with no mistake switch operation
  • Headphones control Output for PFL/AFL
  • Li-Ion AccuPack with microprocessor controlled battery management
  • 10 hour full load capacity. Note: AccuPack is placed inside the unit
