Introduction
10-Channel stereo preamplifiers
The PRE2xx series preamplifiers are solutions for applications where a large number (up to
8) of microphones (or other mono balanced audio inputs) need to be mixed to two output
zones. The multifunctional stereo design with a total of 10 inputs allows connection for any
type of audio source such as microphones, Bluetooth devices or line level audio sources.
Channels one to eight are balanced inputs, allowing the connection of microphones or line
level audio sources with the ability of enabling 48V phantom power to each input. They
feature 3-band tone control and talk-over for priority announcements. The other two (9
and 10) inputs are unbalanced stereo line inputs allowing connection of any type of line level
audio source.
An integrated Bluetooth receiver and a front panel 3.5 mm jack offer convenient wired
or wireless connection possibilities for mobile and portable devices including laptops,
smartphones and tablets. The front panel includes a master volume control with 2-band
tone control and LED VU bar for each output.
Each input section is accommodated with input mixing dials and output selection switches.
A priority mute for each zone output suppresses all (non-priority) music sources in case of
contact closure, allowing linking autonomous alarm systems.
