AQ-3 Operating Instructions
Output connector C
For bi-amped operation connect as above.
For bridged operation connect as follows:
Channels A & B +ve = channel B +ve
(pin +1 on connector B or +2 on connector A)
-ve = channel A –ve (pin -1 on connector A)
Channels C & D +ve = channel D +ve
(pin +1 on connector D or +2 on connector C)
-ve = channel C –ve (pin -1 on connector C)
Note: Both level controls must be set to the same position.
When operating in bridged mode, the minimum impedances are 8 ohms.
Note: 1. Negative (-ve) output terminals must not be joined together, since they
are not both at 0V.
2. Because the currents involved are very high, the speaker cables should
conform to the following minimum requirements, otherwise the losses
will cause the cables to get hot and audio power will be reduced:
3. Do not connect the inputs/outputs to any other voltage source such as a
battery, mains source or power supply, regardless of whether the
amplifier is turned on or off.
3. Do not run the output of any amplifier channel back into another
channel's input and do not parallel or series-connect an amplifier output
with any other amplifier output.
