DESIGN FEATURES

Handcrafted in the U.S.A. with mii-spec glass epoxy circuit boards, low- loss connections, gold-plated input connectors, and metal film resistors.

Darlington High Current Discrete Output Topology - Soundstream’s “overbuilding” of the output section incorporates Darlington output devices sandwiched between the circuit board and the heatsink in a design called ChassisinkTM to ensure cool, efficient amplifier operation.

Mixed Mono Capable so you can simultaneously drive a stereo and mono load (satellites and subwoofer).

2 Ohm Drive Ability - Soundstream amplifiers are designed to drive loads down to 2 Ohms stereo and 4 Ohms bridged.

Built-in Staggered Asymmetrical Crossover - Built in 2-way(l-way on SA-80) electronic crossover is designed to send either high or low pass information to the amplifier.

Drive DelayTM Muted Turn-on/off Circuit - A unique circuit which completely eliminates any amplifier-related turn-on/off noises.

Flexible Input Sensitivity - Accepts input voltages from 100 mV to 2.5 V, which permits maximum output from amplifier with virtually any source unit.

SETTING THE CROSSOVER MODES

The Soundstream SA*80 & 164 incorporate a defeatable electronic crossover for each pair of channels. The SA.164 amplifier can drive a complete system without need of an outboard electronic crossover.

Before installing the amplifier, make certain the switches on the bottom are set to the correct positions.

LOWPASS

The low pass crossover is used for sending only low frequency information to particular speakers. Activate the low pass crossover if you intend to drive subwoofers.

HIGH PASS (SA*I 64)

The high pass crossover is used for sending only midrange and high frequency information to particular speakers. Activate the high pass crossover if you intend to drive satellite or coaxial speakers in the system along with subwoofers driven off channels 1 & 2 in low pass. Even if your system does not include subwoofers, it may be helpful to activate the high pass crossover with smaller speakers to protect them from low frequency information.
