1 POWER CONNECTOR WITH FUSE HOLDER
Always make certain that the operating voltage of the power amplifier (printed on the rear panel of the power
amplifier) matches the mains voltage in your region. An appropriate mains cord is included in the package.
Always disconnect the power amplifier from the mains power during installation.
IMPORTANT INFORMATION: Always replace the fuse only with a fuse of the same type with the same rating
(printed on the rear panel of the power amplifier). If the fuse blows repeatedly, please contact an authorised
service centre.
2 BALANCED XLR-INPUT CHANNEL A AND B
The XLR input sockets are used to connect to a mixing desk or another signal source.
In bridge mode BTL (bridge tied load), Channel A must be used as the input.
3 BALANCED JACK INPUT / LINK OUPUT
These 6.3 mm TRS sockets can be used as an audio input or to loop through the signals from the XLR
input sockets. Unbalanced instrument cables can also be used, but when looping through the signal with
unbalanced instrument cables, it is important to remember that this automatically makes the input signal of
the power amplifier unbalanced.
4 SPEAKON-COMPATIBLE SPEAKER OUTPUTS CHANNEL A AND B
Connection of speakers or speaker systems with a total impedance of at least 4 ohms per channel.
In bridge mode BTL (bridge tied load), the Channel A output socket must be used, whereby it must be ensu-
red that pin 2+ and 2- of the Speakon-compatible sockets are used.
IMPORTANT: In bridge mode, the total impedance of the connected speaker system must not be less than 8
ohms.
