GT-series Amplifiers: The Boston Acoustics GT-2200 amplifier
is part of the GT-series of amplifiers, which feature high efficiency and output
stages that deliver increased power into lower impedances, and maximum dynamics
and transient response. The advanced fan cooling system allows you to mount the
GT-series amps in varied positions. The low profile design and adjustable mounting
feet make installation in tight locations much easier.
1-Ohm Stable: The GT-2200 can be connected to loads with
impedances as low as 1 Ohm stereo or 2 Ohms mono. The lower the impedance, the
higher the output power:
- 200 watts x 2 @ 4 ohm stereo
- 350 watts x 2 @ 2 ohm stereo
- 450 watts x 2 @ 1 ohm stereo
- 700 watts x 1 @ 4 ohm mono
- 900 watts x 1 @ 2 ohm mono
Top-mounted AFS Fuse: The amp is equipped with a 70-amp AFS-type
fuse, located on the top panel under the removable cover. The fuse is held in place
by 2 Phillips-head screws.
Adjustable Mounting Feet: The mounting feet on the GT-2200
can slide along the front and rear edges, allowing you to adjust the mounting
points of the amplifier. The feet can adjust between 3/4" and 16-1/8".
Top-mounted Controls: The amplifier has controls conveniently
mounted on the top panel under a removable cover. The controls include:
- Signal: This 2-way switch allows you
to choose the type of input signal: "Stereo" or
"Mono" (if "Mono" is selected, the left
channel input only is used)
- GT-RSL: This 2-way switch allows you
to turn on or off the optional Remote Subwoofer Level
Controller (item # 065GTRSL--see below).
- Low-pass Filter: The amp has a rotary
control to select the cutoff frequency between 50 Hz and
350 Hz. In addition, a 3-way switch lets you select a slope
of 12 dB/octave stereo, 12 dB/octave mono, or 24 dB/octave
mono. A second 2-way switch lets you turn the low-pass
filter "On" or "Off".
- High-pass Filter: Using the rotary
control, you can select a cutoff frequency between 20 Hz
and 350 Hz. A 2-way switch allows you to turn the high-pass
filter On or Off.
- Q-Tune: Once the high-pass crossover
point has been determined, you can use the rotary Q-Tune
control to increase the bass information centered around
the crossover point.
- Input Sensitivity: You can adjust the
level of the input signal with this rotary control. Range
is 0.2 Volts to 8.0 Volts.
Remote Subwoofer Level (GT-RSL): The GT-2200 has a front-mounted
port for connecting the optional GT-RSL Remote Subwoofer Level Controller for GT
sold separately). When the GT-RSL is connected and switched on, you can control
the level of the subwoofer independent of the main sound system volume control. The
GT-RSL has a 4-meter cable and a dash-mountable rotary control knob.
Front-mounted Terminals: The GT-2200 has all of the cable
connections on the front of the amplifier for a clean installation. The terminals
- Input: Left and right RCA jacks for
the input signal from the head unit.
- Remote: A 0.25" male quick slide
for connecting the remote turn-on lead from the head unit.
A 0.25" female quick slide is included for terminating
your remote lead.
- GT-RSL: A multi-pin port, covered by
a removable plate, for connecting an optional GT-RSL Remote
Subwoofer Level Controller (065GTRSL).
- Speaker Outputs: Two pairs of set-screw
terminals are provided for connecting a pair of speakers.
The terminals can accept up to 12-gauge wire. The set screws
can be tightened/loosened with the supplied 2mm Hex wrench.
Note: You must first remove the top cover
in order to access the set screws for the speaker and power
- Power Input: Two set-screw terminals
are provided for connecting the power and ground cables.
The terminals can accept up to 4-gauge wire, and 4-gauge
wire is recommended. The set screws can be tightened/loosened
with the supplied 3mm Hex wrench.
