Terminals marked

with are HAZARDOUS LIVE. External wiring to these terminals/ connectors requires installation by trained personnel, or pre- manufactured cables

1.3-Pin Euroblock Input Connectors – These connectors are used for all input signals.

2.Input Switches – The HPF switch sets the High Pass Filter for each pair of channels channel to 80Hz or Off. The Gain switch sets the amplifier gain to +36dB or +26dB sensitivity. The Mode switch selects the amplifier’s operating mode (Bridge or Stereo).

3.Screw Terminal Output Connectors – These connectors provide the amplifiers output signal. In Bridge Mode, the even channel (+) connector becomes the Bridged Channel (-).

4.Standby Connector – This 2-Pin Euroblock connector provides for remote standby switching. The Power switch must be in the On position for the Standby connector to be active. This feature includes a 0.5 second turn-on delay.

5.Delay Switches – These switches provide additional turn-on delay when the Standby connector is used. The switches are additive, providing as much as 7.5 seconds of delay to the 0.5 second Standby delay.

6.Mains Connector - Connection to the mains is via this 3-Prong IEC connector

WARNING: Do not remove the mains connector ground. It is illegal and dangerous.
