CONGRATULATlONS
You now own the Soundstream Granite Amplifier, the result of a unique design and
engineering philosophy.
To maximize the performance of your system, we recommend that you thoroughly
acquaint yourself with its capabilities and features. Please retain this manual and
your sales and installation receipts for future reference.
Soundstream amplifiers are the result of American craftsmanship and the highest
quality control standards, and if properly installed, should provide you with many
years of listening pleasure. Should your amplifier ever need service or replacement
due to theft, please record the following information, which will help protect your
investment.

CAUTION!
Prolonged listening at high levels may result in hearing loss. Even though your new
Soundstream amplifier sounds better than anything you’ve ever heard, exercise
caution to prevent hearing damage.
DESlGN FEATURES
Handcrafted in the U.S.A. with mil-spec glass epoxy circuit boards, low-loss con-
nections, gold plated input connectors, and metal film resistors.
Darlington High Current Discrete Output Topology - Soundstream’s “overbuild
ing” of the output section incorporates Darlington output devices sandwiched
between the circuit board and the heat sink 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 - The Granite amplifiers are designed to drive loads all the
way down to 2 Ohms stereo and 4 Ohms bridged.
Built-in Staggered Asymmetrical Crossovers (Granite 120.4, Granite 180.6) -
Built-in electronic crossovers are designed to compensate for the acoustics of
the automobile environment. A high pass crossover (at 150 Hz @ 12 dB/octave)
and low pass crossover (at 75 Hz @ 12 dB/octave) allow you to drive a com-
plete subwoofer and satellite system without the use of passive crossovers.

l Internal Signal Routing (Granite 120.4, Granite 180.6) - Permits one pair of
signal cables to drive all 4 channels (Granite 120.4) or two pairs of signal cables
to drive all 6 channels (Granite 180.6).
l Drive Delay Muted Tunum/off Circuit - a unique circuit which completely elimi-
nates any amplifier-related turn-on/off noises.
l Flexible Input Sensitivity - accepts input voltages from 100 mV to 2.5 V, 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.
Your Granite amplifier comes with a limited warranty. Refer to the enclosed
warranty card for length of warranty and conditions.

SWITCH SETTINGS (bottom of amp)
For each pair of’channels, there are two switches (one on 60.2) accessible from
the bottom of the amplifier.
Mono/Stereo Switch: Set to “Mono” to bridge one pair of channels into a
single channel. Only Right channel input is active. When in “Stereo,” a mono
channel can be driven using Left - & Right + speaker outputs.
Crossover Switch (Granite 120.4, Granite 180.6): Defeatable high or low
pass crossover. Frequencies are set at 150 Hz, 12 dB/octave on the high
pass and 75 Hz, 12 dB/octave on the low pass.

bridged Granite amplifiers.
