Soundstream Technologies SA.244 - Manual (Page 7)

INSTALLATION STEP 2
In most car audio installations, there is a tendency for a boom.”
Because of their interior dimensions, most cars will resonate or ring at these
frequencies. If we design the system so there is less musical
information in this region, the final response is very smooth and natural
sounding.

The 244,
incorporate a staggered
electronic crossover. The high
and low pass portions of the
crossover can be
set
independent of one another.
Below is a chart of S.I.P. values
which can be used for changing
the factory preset crossover
points (low pass only on SA-245).

Your multi-channel Soundstream amplifiir can be driven
either one or two pairs of stereo inputs (three with the If your source unit
has front and rear outputs, you can take advantage of its fading capability by
driving the multi-channel amplifiers with two pairs of input In addition, if you have
another amplifier, you can drive it with the outputs of the
or 244. When
operating a pair of amplifier channels in mono, only one input is necessary.
On amplifiers, pairs of channels may be bridged for mono
operation. To do so, simply put the stereo switch into the ‘mono” position and
follow the mono wiring (Right Positive goes to speaker’s positive; Left Negative
goes to speaker negative).
Stereo for normal operation.
in order to drive stereo and mono simultaneously; works well for
center channels. It can be used anytime you need a summed mono channel. It
also makes for a cost-effective means of driving an entire system with only 2
channels of amplification.
for dedicated single channel operation; ideal for driving
subwoofers. It is also used when large amounts of power are necessary for
single speakers.
