S Series – S1400/800 Operating Instructions
Page 11
Connecting To Your Amplifier: Speaker Outputs
The speaker outputs are via Neutrik Speakon connectors. 2 pole (NL2FC) or 4 pole (NL4FC)
connectors can be used.
Pin 1+: Hot
Pin 1-: Cold
Additionally Channel A Speakon connector carries Channel B output on Pins +2 & -2 to allow
easy bi-amping or bridged operation using a single NL4 connector.
Pin 2+: Hot Ch. B
Pin 2-: Cold Ch. B
There must be no shared connections between channels.
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:
S800, 12A into 4 Ohm speaker loads
S1400, 16A 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.
Connecting To Your Amplifier: Bridged (Mono) Operation
Supply signal to Channel A input only and push in the rear panel switch marked “Bridged
Mono”.
Use Channel A Output Speakon connector and connect as follows:
Pin 2+: Hot
Pin 1-: Cold
When operating in bridged mode, the minimum impedances are doubled.
The minimum load in bridged mode is 4 ohms.
