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.

Mixed-Mono in order to drive stereo and mono simultaneously; works well for center channels. It can be used anytime you need a summed mono channel.

Bridged MOfIO for dedicated single channel operation: ideal for driving 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.

WIRING

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

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.
