How to connect your system
Please read this page carefully and see page 5 and page 6.
Inputs
For optimal performance, the AW400 should be used in balanced mode.
(ie. the preamplifier should have balanced outputs.)
Input configurations Diagram 3
XLR input: 1 = ground 2 = positive 3 = negative
Outputs
Switch the amplifier off when connecting the speakers.
Output configurations Diagram 3
Speaker: Red = positive White = negative
Please notice:
Both outputs are hot.
Do not under any circumstances short these to ground or chassis.
Input level adjustment
Located on the rear side.
Factory setting of the level adjustment is max volume.
Use it to match levels between amplifiers in bi-amping system.
Link
This output can be used to link more amplifiers together.
The output level on the link output is independent of the input level set on the
amplifier.
Do not short these outputs to ground or together.
How to power up your system
You should always power up your system the following way:
Signal sources (CD player, tuner etc.) first. Then turn on the preamplifier. Allow
30 seconds of preheating before you turn on the power amplifier. After switching
on the power amplifier, there will be a 5 seconds delay before the speakers are
connected. This will prevent large turn on/off transients to reach the speakers.
When turning your system off, you should start by switching off your power
amplifier, then the preamplifier, and finally the signal source devices.
