Las Vegas – Boston
Acoustics is introducing six GTA series that boost output up to 25 percent over
their predecessors without boosting prices.
The amps, shipping in
April, consist of two-, one-, and five-channel models price from a suggested
$299 to $499. They are the:
$199, a 2×60-watt AB amplifier;
$249, a 2×80-watt AB amplifier;
$249, a 4×70-watt AB amplifier;
$299, a 1×500-watt Class D amplifier;
$499, a 1×1,000-watt Class D amplifier; and
$499, a five-channel 4×70-watt plus 1×400-watt hybrid AB-Class D amplifier.
All models feature
adjustable 12dB/octave high-pass and 12dB/octave low-pass crossovers. The
crossovers can be combined in the Class D models for band-pass operation, using
the high-pass crossover as a subsonic filer, Boston said.
The company has also
incorporated Q-Tune bass enhancement in all models, and, in the Class D models,
user-adjustable “Q” for each amplifier’s high-pass crossover filter.
Other features include
its Symmetrical Signal Topology (SST) system, said to use balanced asymmetrical
inputs for noise cancellation; an extruded aluminum chassis; and the Integral
Mounting System (IMS), which allows for direct mounting without the need for
extended mounting feet or tabs.
The company is also showing
the $19.95-suggested GTA-RSL, an optional remote level control that delivers independent
level adjustment of the subwoofer’s output level.
