Many popular mixers use unbalanced outputs and can be used with the Hafler amplifier. To minimize residual
ground noise, we recommend using twisted pair cable or short cable lengths in this type of configuration.
XLR Unbalanced Input
Connect (–) and GND (shield) terminals at both ends of cable to
prevent unstable amplifier operation

INPUT
The input jacks located on the back of the amplifier are dual function connectors which accept 1/4" Phone (Tip
Ring Sleeve) or XLR plugs. The 1/4" Phone jack is connected according to conventional usage. The XLR jack is
connected according to the IEC and AES standard.
OUTPUT CONNECTIONS
The speaker output connectors are dual binding posts. These binding posts will directly accept 12 AWG wire
or banana plugs and are spaced on 3/4" centers to accept dual banana plugs.
MONOPHONIC USE
For systems with high power requirements, the amplifiers can be configured for single channel bridged mono
operation. To bridge the amplifier, set the front panel Normal/Bridged Mono switch to the Bridged Mono
position. Only the Channel 1 input and level control is used. The speaker is connected to the RED output binding
posts.
