Selecting Input Modes - Soundstream SA 164 Owner's Manual And Installation Manual

SELECTING INPUT MODES

The SA*164 can be driven with either one or two pairs of stereo inputs. 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. When
operating your Soundstream amplifier in mono, only one input is necessary.
On Soundstream 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.

subwoofers. It is also used when large amounts of power are necessary for single
speakers. In bridged mono, on/y the right channel input (per pair of
channels) is active.

POWER AND GROUND
To assure maximum output from your amplifier, use high quality, low-loss power
and ground cables. Soundstream SA amplifiers incorporate gold-plated barrier
strips for maximum power transfer and protection from corrosion. The screw
terminals back out for use with spade & ring terminals, as well as bare wire.
Determine from the chart below the minimum gauge power and ground wire for
your application.
CIRCUIT BREAKERS/FUSES
EXTERNAL
Like all audio components, the Soundstream amplifiers must be fused near the
battery. A fuse or circuit breaker must be located within 18" of the battery. This
will prevent a fire in the event of a shorted cable. See the chart below to
determine the value of your battery fuselcircuit breaker.
