- When linking the same source
signal to several input channels,
be aware that there is a limit to
the number of channels an
output source can drive,
A typical output source (e.g. a
DSP crossover unit) can drive
up to four amplifier channels
before external line-drivers
might be required to buffer the signal.
7.4.2 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.
7.4.3 SpeakON output connections
Amplifier is equipped with the Speakon output
connectors.
SpeakON inputs – two channel models
