CONNECTIONS
Inputs
The connection of the inputs depends on the operating mode selected. Therefore, prior to making any
connections, select the operating mode according to your desired application. Then connect the output of
line signal sources (e.g. preamplifier or mixer) to the balanced XLR inputs CH-1-CH4.
Feed-through Output
For parallel connection of further PA amplifiers, the feed-through outputs can be used via the balanced XLR
jacks LINK 1-4. Connect the outputs to the inputs of the PA amplifiers.
XLR connection
Speaker Outputs
In stereo and parallel mode, the amplifier can operate four speakers or four speaker groups. To double the
output power, channels 1, 2 and/or 3, 4 can be bridged to drive one speaker or speaker group each. For
connecting speakers, Speakon jacks are provided. Turn each plug to the right until it locks into place. For
unlocking, pull the unlock button and turn the plug to the left. When interconnecting several speakers, it is
especially important to consider that the minimum total impedance is 2
Ω
for stereo and parallel operation
and 4
Ω
for bridge operation.

ACHTUNG!
All connections have to be made or changed only if the amplifier is switched off!
