WARNING! THIS APPLIANCE MUST BE GROUNDED.

The amplifier must always be connected to a 3-wire grounded AC outlet. The rack framework must also be connected to the same grounding circuit. The unit must NOT be operated unless the power cables' ground wire is properly terminated - this is important for personal safety as well as for proper control over the system grounding.

The wires in the power lead are color coded as follows:

 

 

Green and Yellow

Ground

Blue

Neutral

Brown

Live/Hot

IMPORTANT: The PULSE 2x1100 is designed to use 50/60Hz AC power. Acceptable AC input supply voltage ranges from 180V to 265V

The application of voltages above those specified may cause permanent damage that is not covered by your warranty. Lower voltages may cause erratic operation.

Note that although the amplifier will operate correctly down to the voltages indicated, the quoted output power will only be achieved with the stated nominal voltages.

IMPORTANT : The AC power fuse carrier on the rear of the unit must be fitted with the correct type and rating of fuse, in this case T10A.

In the unlikely event of the AC fuse failing without good reason, disconnect the unit from the power supply, and always replace with the appropriately rated fuse (as specified above) for continued protection against damage and fire.
