The Audac PRE126 is a two zone, 6 channel stereo pre-amplifier providing a variety of input possibilities for microphone and line level audio signals.

It features two balanced mono inputs with phantom power each with three band tone control allowing connection of microphones or line level signal sources.

The switchable talkover function suppresses background music if a priority signal is present, making it suitable for paging or voice file announcements.

The four stereo line level inputs consist of one balanced input fitted with XLR connectors and three unbalanced RCA inputs for maximum flexibility. 

An integrated Bluetooth receiver (mixed with Ch 3) and 3.5 mm jack connection on its front panel (mixed with Ch 4) offer convenient wired or wireless connection possibilities for portable and handheld devices including laptops, smartphones and tablets.

A priority mute contact suppresses all (non-priority) music sources in case of contact closure, allowing to link autonomous alarm systems.

Input volume control is done using the corresponding rotary dials on the front panel, while routing settings are made through zone selection buttons.The output section features a 6-segment LED VU bar, a master volume control and 2-band tone control.

Gain adjustment and mono/stereo switching is accessed via the controls on the rear.
