6-Channel stereo preamplifiers

The PRE1xx series are simple but versatile preamplifiers, offering a multifunctional solution

for installations where multiple voice and music sources need to be mixed to one or two

(only PRE126) output zones. The stereo design with six inputs allows connecting any type

of audio source such as microphones, portable devices with Bluetooth and various balanced

or unbalanced line level audio sources.

Channels one and two are balanced inputs, allowing connection of microphone and line level

audio sources. They feature 3-band tone control, phantom power and talk over for priority

announcements. The other inputs are one balanced and three unbalanced stereo line inputs

allowing connection of any line level audio sources.

An integrated Bluetooth receiver and a front panel 3.5mm jack offers convenient wired

or wireless connection possibilities for mobile and portable devices including laptops,

smartphones and tablets.

A master volume control for the output(s) including 2-band tone control and LED VU bar is

located on the front panel, also accommodating each inputs mixing dial. On the back of the

preamplifier is a priority mute contact that suppresses all (non-priority) music sources in

case of contact closure, allowing linking autonomous alarm systems.
