audio input and output connections
Balanced input connections
The XLR in pul conncctors are eleetronieally balanced, and wircd according to the IEC 268 standa rd(pin 2 = hot). XLR inp u1
connectors should be wiredas fo llows:
Unbalanced input connections
To connect an input to an unbalanced source, it is possible to connect pins 1 and 3 in the XLR plug at the amplifier end of the cable.
However, a better method is to connect pin 3 to the shield at the source end of the cable, as this usually results in better hum and
noise rejection . Balanced input connections are recommended whenever possible.
SpeakOn output connections
Refer to the instructions in this section if your amplifier is equipped wilh the Speakon output connectors.
Speakon outputs - 4-channel models.
When linking the same source signal to several input channels,
be aware that there is a limit to the number of channels an
outout source can drive. A typical output source (e.g. a DSP
crossover unit) can drive up to two amplifier channels before
external line-drivers might be required to buffer the signal.
!
The four core interface provides two
channel outputs.
