Audio Press Box APB-224-C Active Press Box, 2 MIC/LINE In, 24 LINE/MIC Out, Built In battery

Designed for quick, easy distribution of high-quality audio feeds for indoor and outdoor press conferences, the APB-224-C is a 2-input 24-output distribution amplifier with a built-in Li-Ion battery in a custom Nanuk road case.

A pair of balanced switchable Mic/Line inputs feed 24 balanced transformer-isolated Mic/Line outputs giving you the field flexibility you need to interface with a wide variety of press pool gear. The ouputs are arranged in groups of 12 with the option to route each input to group A, A+B, or B. The inputs also feature switchable phantom power allowing the use of condenser microphones. A 26dB pad with integrated compression and limiting on each input helps ensure an even undistorted signal is sent to all outputs, no matter the input source. A front panel headphone output with independent level control allows you to monitor and verify the output signal at both the A and B output bus.

The APB-224-C is portable and comes in a custom waterproof Nanuk road case with a built-in Li-Ion AccuPack Battery. The 10-hour runtime 2200mAh rechargeable battery features microprocessor-controlled battery management with a front panel status meter to avoid unpleasant in-the-field surprises. A 24V DC external power supply is also included.
