05)
Carefully install the front glass and top rails (see detailed directions in the next section of this
manual). Take care not to chip or scratch the glass.
06)
Set the top switch to Balanced (for use with balanced sources on
XLR connector) or Single-ended (via RCA connector) as desired.
07)
Set the front panel SELECT switch fully
counterclockwise for full volume input, or clockwise
if you wish to attenuate volume using the front panel
VOLUME control.
08)
Install the input cable in the back panel jack that corresponds to the switch settings selected
above.
09)
Connect the speaker cables; the black lead goes to “-“ or “Ground”. The red lead goes to
“+” or “Positive”. Follow the label on the back of the amplifier for the impedance that best
matches your loudspeakers.
10)
Connect 12 volt trigger input cables into the appropriate sockets on the back panel if
desired; either will slave the off/on function to the external connection.
11)
Provide adequate ventilation - allow at least 3 inches above and to each side.
12)
Do not place in a completely enclosed cabinet. Do not stack other equipment on top of the
VAC unit.
13)
Do not operate on carpet or any other surface that might block air flow.
14)
The chassis and glass will become hot in normal use.
15)
The power supply may produce a small mechanical hum; therefore avoid placing the system
on any surface that could act as a sounding board, or at any location in the room that
corresponds to a resonance at your local power frequency (50 Hz. or 60 Hz.).
16)
Do not allow the chassis to touch any metal parts, such as the frame of an equipment rack.
This might create a parallel ground path that could degrade the sound of your system.
