1: IEC POWER INLET: Before the initial power up, ensure the Supply Voltage Rating (located above the power socket) is
compliant with your local mains supply.
Disconnect the power connector when the amplifier is not in use!
The unit must be earthed under all circumstances!
2: RESET: A protection device for the amplifier output stage. It is activated if the amplifier is driven into a short circuit or any
prolonged over-current situation, such as driving into impedances too low, at too high power for too long.
Normal operation will resume once the fault has been removed and the Reset button pressed.
3: SAFETY INFORMATION.
4: OUTPUT SECTION: Two SpeakON output connectors and 4mm binding post terminals corresponding to the two channels
of the amplifier. Connect loudspeakers to either the SpeakON Outputs or the Terminal Posts.
The 4mm binding posts are located behind a safety cover. To access, first remove the screw securing the plastic cover.
Please DO NOT use instrument or microphone cables to connect your amplifier and speaker cabinet!
The amplifier will drive a minimum speaker impedance of 4Ω in Stereo or Parallel mode and 8Ω in Bridge mode.
5: COOLING FANS: Two variable speed fans to cool the unit. DO NOT OBSTRUCT!
6: INPUT SECTION: Two XLR Input connectors accepting single ended and balanced inputs - Pin 2 hot. Balanced signals are
recommended for improved signal to noise ratio.
LINK OUTPUTS: Internally routed from the Input XLR's, the Link Outputs (Pin 2 hot) can be used to daisy-chain an additional
device.
SENSITIVITY CONTROL: Two options available: 0.775V and 1.4V. The setting used will depend on the level of the source
device.
MODE SWITCH: Provides three operating modes:
STEREO:
Channel 1 Input
Channel 2 Input
PARALLEL:
Channel 1 Input
Channel 1 Input
BRIDGE:
Channel 1 Input
Channel 2 Input, Gain Control and output is disabled.
