Manual-1
QUICK START
Whoa, hold on there. Even if you don’t read manuals as a matter of principle, at least read this section to avoid hurting
yourself or your equipment.
Connect the SAC 22 with the power
off
. Balanced XLR cables are recommended, but if you must convert to ¼" connec-
tors, buy or make a cable like the ones on page Manual-11 and keep them as short as possible.
This device uses low imped-
ance balanced line drivers. Do not connect the “+” or “–” output pins to ground, as this may cause the power supply to
shut down. For unbalanced use, leave the unused output pin (“+” or “–”) unterminated.
Consult the speaker manufacturer for the correct crossover
FREQUENCY
setting. As rugged as some drivers are, many
(especially compression drivers) will not accept frequencies outside of their normal range without producing distortion and
possibly self-destruction.
With all equipment turned off and
LEVEL
controls down, begin making connections to the system as shown on page
Manual-4 or 5. When turning on the system, switch on the power amplifiers
last
. Now, feed the SAC 22 some program
material. Start by turning up the
LOW LEVEL
and
HIGH LEVEL
to the
0 dB
marks. Slowly increase the
INPUT
LEVEL
, even if it goes all the way to
10
, so the
+4 dBu
(green) light blinks occasionally and the
OL
(red) light stays out.
This delivers the best signal-to-noise performance.
The
MONO SUB OUTPUT
is a sum of the Left and Right Low Outputs. The
MONO SUB LEVEL
adjusts only this
Output and is not affected by the
LOW LEVEL
control.. When using a single subwoofer along with full-range cabinets
that have internal crossovers, set the
100 Hz FILTER
to
OUT
, allowing the front panel
FREQUENCY
to control the
subwoofer crossover point. When used with biamp cabinets and a subwoofer, set the
100 Hz FILTER
switch to
IN
to allow
only frequencies below 100 Hz at this output jack. This way, the SAC 22 almost does the job of a Stereo 3-Way crossover,
but without removing that awesome bass from the Left and Right Low Outputs.
