The PRE220 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.
Inputs one up to eight are balanced, 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 3.5mm jack offers 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.

How to use ARJ12P with PRE series
For this application, we used a PRE series stereo preamplifier with a WP2xx series universal wall panel and connected them using an ARJ12P junction box. By connecting any WP2xx universal wall panel, we extended the functionality of the PRE series with a peripheral input with mixing functionality, Bluetooth functionality, or both. As a result, a simple PRE series application gains local input flexibility with such an elegant solution, with the addition of ARJ12p and a 24V power supply (PSD241 in this example).
