POWER SWITCH
To apply power to the unit, flip the switch to the "On" position. The green LED will illuminate, indicating power is
being supplied.
CAUTION: The on/off switch in this unit does not break both sides of the primary mains.
Hazardous energy can be present inside the chassis even when the on/off switch is in the
OFF position.
AC POWER INLET:
15
This is the receptacle for an IEC line cord, which provides AC power to the unit. Connect the line cord to this
connector to provide power to the unit. Damage to the equipment may result if improper line voltage is used. (See
line voltage marking on unit).
Never break off the ground pin on any equipment. It is provided for your safety. If the outlet used does not have
a ground pin, a suitable grounding adapter should be used, and the third wire should be grounded properly.
To prevent the risk of shock or fire hazard, always make sure that the amplifier and all associated equipment is
properly grounded.
NOTE: FOR UK ONLY
As the colors of the wires in the mains lead of this apparatus may not correspond with the colored markings
identifying the terminals in your plug, proceed as follows: (1) The wire that is colored green and yellow must be
connected to the terminal that is marked by the letter E, or by the Earth symbol, or colored green or green and
yellow. (2) The wire that is colored blue must be connected to the terminal that is marked with the letter N, or the
color black. (3) The wire that is colored brown must be connected to the terminal that is marked with the letter L,
or the color red.
16 EXTERNAL SPEAKER OUTPUT
1/4" powered output for powering a passive enclosure.
EFFECTS LOOP
17
The Send Jack provides a pre amp output that may be used to drive slave amplifiers and external effects
processors. The Return Jack provides a power amp input for the last effect in the chain.
NOTE: When using the unit as a slave power amplifier, the Return Jack should be used as the input.
GROUND LIFT
18
This button is provided to prevent a ground loop that may result in "hum" noise. When depressed (IN position),
Ground Lift is engaged.
DIRECT INTERFACE (DI)
19
This is a built-in, balanced Direct Interface used to send a buffered, unprocessed signal to an external mixer.
NOTE: The Direct Interface features failsafe circuitry, which runs on standard 48-volt phantom power from
the mixer. This allows the DI to continue functioning even in the event of a blown circuit breaker or amplifier
shutdown. In the event of a failsafe operation, the mute switch will be bypassed. This circuit is active, even when
the power switch is in the "Off" position.
