Audio Press Box APB-124-SB Active Press Box, 1 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-124-SB is a 1-input 24-output portable distribution amplifier with a built-in Li-Ion battery in an rugged metal housing.

A single balanced switchable Mic/Line input feeds 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 input also features switchable phantom power allowing the use of condenser microphones. Integrated switchable compression and limiting on the input helps ensure an even undistorted signal is sent to all outputs, no matter the input source.

There's also a 160Hz high-pass filter to eliminate annoying low end rumble. A front panel headphone output with independent level control allows you to monitor and verify the output signal.

The APB-124-SB is portable and comes in a custom metal housing 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. The APB-124-SB is equipped with a Link output for daisy chain connection to additional 124-SBs (sold separately).
