PRE240 Four zone - 10 Channel stereo preamplifier

Four zone - 10 Channel stereo preamplifier

The PRE240 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 into four 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 to enable 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 the 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.
