2.  Control Elements 

2.1. 

Microphone channels 

(1) These are the balanced XLR connectors for dynamic microphones. 

 

(2) Using the 3-band microphone equalizer ( and ), you can change the sound 

of your voice and optimally adjust it (+/-15 dB). 

HIGH,MID LOW 

 

(3) The control adjusts the volume of the MIC AUX send signal laid out at the rear panel MIC 

AUX SEND connector (see (38) )

(4) Use the 

VOL 

control to adjust the microphone signal volume. 

Your PRO MIXER features a talk over function. It works very simply: as soon as you talk into 

your mike while a track is playing, the track s volume is lowered.When talking to the audience, this 

function is useful because it makes your voice come through over the music. 

 

(5) Use the 

TALK 

key to activate the talk over function (its LED is lit). 

 

(6) The control changes the sensitivity of the talk over function. The lower it is set, the louder 

does the mike signal need to be in order to suppress the music signal.

(7) Use the 

DPT 

control to determine the extent to which the music signal is lowered. 

 

(8) Use the switch to activate the microphone channel. If its LED is lit, the channel is 

active. 

2.2. 

Stereo channels 

(9) Select the input signal for the stereo channels using the key. Phono is intended 

for connecting a turntable. Line and CD have to be selected for all other signal sources 

(e. g. CD or MD players). Unlike the first three channels, channels 4 and 5 each feature 

two line inputs. On the rear panel, a special feature lets you change the input sensitivity 

of the phono inputs of channels 1 through 3 to line level, so that you get more flexibility 

(see 36 ). 

 

Never connect equipment with line level signals to the highly sensitive phono inputs! The 

output signal level of turntables is on the order of magnitude of milivolts, while CD players 

and tape decks have signal levels measuring in volts. Simply put, line signals are up to 

100 times stronger than those intended for phono inputs. If you re using phono inputs that
