Art SLA-2 [12/16] Operation

GROUND LIFT SWITCH

This switch is used to disconnect the internal ground signal from the

chassis (case) ground. This may be used to reduce 50/60Hz noise

(hum or buzz). Normally you would ground the chassis, for best

shielding. When the SLA-2 is mounted in a grounded rack of

equipment, the ground to the case may be lifted to prevent multiple

ground paths, which may cause a ground loop to occur.

OPERATION

The main application of the SLA-2 is as a studio linear power amplifier

for powering monitors. Connect source material directly into the inputs

and set the output controls to provide an appropriate level into the next

stage of your system (and an excellent choice for this are the ART

SLM-1 Studio Linear Monitors).

NORMAL OPERATION

For a typical stereo setup, connect the source (mixer, eq, etc.) outputs

into channels one and two of the amplifier. Connect your speakers to

the outputs on the rear of the amplifier. Be sure that your front gain

controls are turned down to their lowest level (full counter-clockwise).

Turn the amp on, then slowly turn the input level up. Use the front gain

controls to regulate the output volume. Be sure not to raise the volume

past the clip level; however, an intermittent clip signal is acceptable.
