connecting your SPM 1400E
SPM 6000
You need to connect the outputs from your pre-amplifier to your power amplifiers
and then connect your power amplifiers to your loudspeakers. There are two pairs of
inputs. You can connect to either the XLR or RCA outputs, but not to both types at
the same time. All connections should be made with the power turned off.
The inputs can be connected as either inverting or non-inverting modes. Connect the
output from your Chord pre-amplifier to the right input to give an inverted output,
as is normal with other Chord amplifiers.
Connect the output from your pre-amplifier to the left input to give a non-inverting
output, when using other makes of amplifier.
As these amplifiers are of mono block construction you should only connect one
input. When using a pair of units you need to ensure that all inputs used are
non-inverting or both are inverting otherwise the loudspeakers will be out of phase.
connecting to your power amplifier using XLR style inputs
Use XLR style connectors to connect the output of your pre-amplifier to the Right
balanced inverting input.
connecting to your power amplifier using unbalanced RCA style inputs
Use RCA style connectors to connect the output of your pre-amplifier to the Right
inverting input phono socket.
connecting your loudspeakers
Connect your loudspeaker to the black and red binding posts.
To bi-wire using two mono power amplifiers see Figure D on page 22.
