2. Description of the control elements and sockets
microphone
A dynamic or a condensor microphone with XLR plug can be connected to
this XLR socket.
(Pin assignment: 1 = ground, 2 = hot (+), 3 = cold (-)
ATTENTION!
If a phantom-powered condensor microphone is used, the jumper J4 on PCB
80402.1 must be plugged to Phantom ON.
volume 1
This is the volume control of the microphone input. Here the desired volume of the
connected microphone can be adjusted.
bass 1
The low frequencies of the microphone signal can be boosted or cut with this
bass control.
treble 1
The high frequencies of the microphone signal can be boosted or cut with this
treble control.
tape/cd/dat
A stereo cinch cable from a tape deck, CD player, tuner etc. can be connected to this pair
of cinch (RCA) sockets. The sensitivity is 775 mV. (Standard configuration)
The inputs left and right are summed to mono. Mono signal sources must be plugged to
socket left!
volume 2
This is the volume control of the line input. Here the volume of the connected
AF source can be adjusted.
bass 2
The low frequencies of the AF source can be boosted or cut with this bass control.
treble 2
The high frequencies of the AF source can be boosted or cut with this treble control.
mute/damping/mix
The 3 positions of this mode switch mean:
mute -
the module UV 300 is muted, the AF output signal is disconnected
from the PA system.
damping -
in this switch position the microphone signal affects the volume
of the AF signal of the cinch input, dependent on the position of
the damping control.
mix -
in this switch position the microphone and the line input are entitled
to the same priority and are mixed together, affected only by the
volume and tone controls. The damping control has no effect.
damping control
With the mode switch in position “damping”, the position of this control determines,
how much the line signal is attenuated, when someone speaks into the microphone
(control range: -6dB ... -20dB).
on LED
This green LED lights up, when the system is switched on and the module is powered.
