APB-312 C-USB BLUE - Overview

The AudioPressBox APB-312 C-USB is a Professional portable, active, pressbox with 2 Analog Line/Mic inputs, 1 Digital USB-C input and output and 8 Analog Line/Mic and 4 Digital USB-C outputs. It is suitable for both indoor and outdoor press conferences due to the heavy duty Nanuk case. The USB-C port also allows a video conference in and out connection for a hybrid press conference.

It features two analog inputs with an input PAD - Mic/ Line switch, one digital input and output, USB interface, and eight analog audio outputs with individual output level switches for Mic/Line and four digital USB audio outputs. Analog inputs also feature a built-in fixed High Pass Filter set to 120Hz and a fixed Compressor with Limiter to ensure high quality output signal without pops common to microphones.

The Mic/Line Switch is an input PAD (-26dB) for selecting the input sensitivity, microphone or line level inputs. With the switch set to Mic you can connect input signal levels from -56dBu to -16dBu and at Line position from -30dBu to +10dBu.

When Mic input level sensitivity is set you can also turn ON the Phantom power for the microphone - please use this with condenser microphones only. When the input sensitivity is set to Line, the Phantom power is automatically turned OFF to avoid damage of connected device.

The Digital USB Video-Conf. In/ Out is for video-conference where signals from both analog inputs are mixed and transmitted to connected device and the audio from the video conference (other side) is mixed with analog inputs and sent to all outputs (analog and also USB). So, the video-conference attendants can hear speakers connected to the AudioPressBox and journalists can record speakers from the room and also speakers attending the videoconference. USB outputs carries the same audio signal as analog XLR outputs. These outputs can be used for live streaming on social media or for digital recording on a laptop or smartphone that supports digital USB audio interface. Nominal output level for USB outputs is -18dBFS.

Each analog XLR output is individually transformer balanced and isolated. You can switch the output level for each output separately to Mic or Line level.
