DESIGN FEATURES
♦
Hand-crafted in the U.S.A. with mil-spec glass epoxy circuit boards, low-
loss connections, gold-plated input connectors, and metal film resistors.
♦
Darlington High Current 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
Chassisink™ 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 - The satellite channels of the USA•305 amplifier are
designed to drive loads down to 2 Ohms stereo (5 channel mode) and 4
Ohms bridged (3 channel mode). The subwoofer channel of the USA•305
is designed to drive loads down to 2 Ohms.
♦
Built-in Staggered Crossover - Built in 2-way electronic crossover is
designed to send either high or low pass information to the amplifier.
♦
Bass EQ - Adjustable bass equalization circuit allows you to boost bass by
as much as +9 dB at 45 Hz. A built-in subsonic filter helps to protect
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 mV to 2.5 V,
which permits maximum output from amplifier with virtually any source
unit.
♦
Differential Balanced Input Topology for added immunity to ground
loops caused by component and vehicle electrical system interaction.
