The mixer is powered via an oversized 19" power supply unit having no difficulty in handling the voltage
changes and voltage peaks typical for live applications.
Every channel features an individually switchable phantom power and 80 Hz low cut. The 4-band EQ is a
bell-filter at 50 Hz and 8 kHz and two semi-parametric mids. Via the bypass switch, you can directly compare
the tone control with or without equalizer.
Via 6 rotary controls, 6 auxiliaries can easily be controlled.
Users who would like to record on several tracks besides the FOH mix have the possibility to use the direct
outs of every channel. In this way, a multi-track recorder can be supplied with constant levels - independently
from the fader position.
Another feature for live-gigs: all channels can be muted via the mute switch so that background music can
be played without annoying stage noise.
Application: mixing console for PA rentals, clubs, youth centers, bands, places of worship.

when using a PA system in public or industrial areas, a series of safety instructions have to be
followed that this manual can only give in part. The operator must therefore inform himself on the current
safety instructions and consider them.
Install the mixer on a solid, plane, anti-slip, vibration-free, oscillation-free and fire-resistant surface.
Switch off the mixer prior to connecting any units or to changing any existing connections.

PSSO MIXER SERIES
This power supply unit (PSU) is built for 19" racks (483 mm) but can also be operated free-standing. In order
