APB-416 C

Active, portable, 4x MIC/LINE routable Input (A, A+B, B), 16 LINE/MIC Outputs, internal AccuPack 10 hours

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 rechargeable 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
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
AudioPressBox delivers audio in broadcast quality

Features

+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 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.

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 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 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

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.

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.

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.

Transformer Separately transformer isolated outputs.

Rechargeable batteries Optional Built-in Li-Ion battery pack with microprocessor controlled battery management, 10 hour working time at full load. No self-discharge and memory effect, always ready to use. Short charging time compared to conventional batteries.
