DESIGN FEATURES

SETTING THE CROSSOVER MODES

Handcrafted in the

U.S.A.

with

glass epoxy circuit boards, low-loss

connections, gold plated input connectors, and metal film resistors.

The Soundstream

244, 245 incorporate a replaceable S.I.P.

electronic crossover for each of their pairs of

channel only on

as well as the outputs

&

The

244, 245

amplifiers can drive a complete system without need of an outboard electronic
crossover.

Darlington High Current Discrete Output Topology Soundstream’s
“overbuilding” of the output
section incorporates Darlington output devices
sandwiched between the circuit board and the heat sink in a design called

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 SA Series amplifiers are designed to
drive loads down to 2 Ohms stereo and 4 Ohms bridged.

Built-in Staggered Asymmetrical Crossover Built in

electronic

crossover is designed to send either high or low pass information to the
amplifier. Outputs are included to drive another amplifier with either high or
low pass information

Bass EQ Adjustable bass equalization circuit allows you to boost bass by
as much as

at 45 Hz. A built in subsonic filter protects speakers.

Drive Delay” 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

to 2.5 V

(from 40

to 2.5 V on the

subwoofer channel), which permits

maximum output from amplifier with virtually any source unit.

“Balancing Act” Input Topology for added immunity to ground loops
caused by component and vehicle electrical system interaction.

INSTALLATION STEP 1

Before installing the amplifier, make certain the switches on the bottom are set

to the correct positions and hole plugs are installed on the bottom of the

amplifier.

CHANNELS 3 4

LOW PASS

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

HIGH PASS

The high pass crossover is used for sending only midrange and high frequency
information to particular speakers (or crossover outputs). Activate the high pass
crossover if you intend to drive satellite or coaxial speakers in the system along
with subwoofers. 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.
