Audio Sources; Speakers And Recording Unit; Connector Configuration; Connection To The Mains - Omnitronic COMBO-150BT User Manual

Switch off the PA system and the units to be connected before making or changing the connections.

Audio Sources

As signal source, microphones, music instruments and audio units with line level can be connected.
1
Combo inputs CH 1 to 4 connect both microphones and units with mono line level output (e.g.
instrument preamplifiers) via XLR or 6.3 mm plugs, balanced and unbalanced.
2
Connect units with stereo output (e.g. keyboard, CD player or laptop) to the 6.3 mm jacks or RCA inputs
of the channels 5 and 6.

Speakers and Recording Unit

1
Connect the left speaker output and the right speaker output SPK (6.3 mm jacks) to the speaker
systems with the speaker cables supplied. The minimum acceptable impedance for each output is 4 Ω.
2
The RCA output REC OUT allows connection of a recording unit. The recording level is independent of
the position of the master level control.

Connector Configuration

Connection to the Mains

Connect the supplied power supply cable to the corresponding input and the mains plug to an outlet (AC 230
V, 50 Hz). The mixer can also be operated with AC 115 V, 60 Hz ~. For this purpose, set the voltage selector
switch to the 115 V position. The occupation of the connection cables is as follows:
Cable Pin
Brown Live
Blue Neutral
Yellow/Green Earth
The earth has to be connected! If the device will be directly connected with the local power supply network, a
disconnection switch with a minimum opening of 3 mm at every pole has to be included in the permanent electrical
installation. The device must only be connected with an electric installation carried out in compliance with the IEC
standards. The electric installation must be equipped with a Residual Current Device (RCD) with a maximum fault current
of 30 mA.
