HS Series – HS1400/800 Operating Instructions
Operating Your Amplifier: Rear Panel Sockets and Switches
1: Fan outlets: The variable speed fans suck air in through the front vents and out through
the back of the amplifier. Please see maintenance on page 15 for recommendations on how
to clean these and the front foam sections.
2: Link out XLR sockets: These are passively connected directly to their respective inputs to
allow for parallel input connections to other amplifiers. As such, they will function even if the
amplifier is turned off.
3: Input XLR sockets: Connect signal inputs to these sockets, wired pin 2 hot, 3 cold, 1
ground. For sensitivity and impedance of these inputs, please see the specifications on page
16. When running in bridged (mono) mode, only input A is used.
4: Bridged (Mono) switch: Depress this switch to run the amplifier in bridged mode. Note
that the output must be taken from channel B and channel A’s binding posts as marked on
the rear panel.
5: Channel A output binding posts: Connect speaker with either bare wires or 4mm banana
plugs. (Note that in bridged mode, the negative terminal only is used for the “cold" side of the
load. No connection is made to the positive terminal in bridged mode.)
6: Channel B output binding posts: Connect speaker with either bare wires or 4mm banana
plugs. (Note that in bridged mode, the positive terminal only is used for the “hot" side of the
load. No connection is made to the negative terminal in bridged mode.)
7: Mains inlet: Connect a suitably rated 3 core IEC mains cable.
