Connecting To Your Amplifier: Speaker Outputs
The speaker outputs are via Neutrik SpeakON TM connectors. 2 pole (NL2FC) or 4 pole (NL4FC)
connectors can be used.
Pin 1+: Hot
Pin 1-: Cold
Additionally the Channel A SpeakON
TM connector carries Channel B output on Pins +2 & -2 to
allow easy bi-amping or bridged operation using a single NL4 connector. Similarly, Channel
C’s SpeakON
TM connector also carries Channel D output.
Output Connector A
Pin 2+: Hot Ch. B
Pin 2-: Cold Ch. B
Output Connector C
Pin 2+: Hot Ch. D
Pin 2-: Cold Ch. D
For bi-amped operation, connect as above.
There must be no shared connections between channels.
Negative output terminals must not be joined together as they are not both at
ground potential. Connecting them together will damage the amplifier and void
the warranty!
As the currents involved are very high, and to ensure best performance, the speaker cables
should be kept as short as possible and conform to the following minimum requirements:
AQ-10, 20A into 4 Ohm speaker loads
When operating the amplifier into loads of less than 4 Ohms, be aware that the current
capacity of the speaker cables will need to be increased above the values quoted here.
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.
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.
