Delivers Innovative Features, High Performance, and Great Value
Boston Acoustics, a longtime leader in premium sound components for aftermarket mobile audio systems, introduces the GTA Series, an entirely new line of high-performance mobile audio amplifiers comprising six models ranging from 50Wx2 all the way up to an 800W monoblock.
“The new GTA amplifiers offer a tremendous value while staying true to the standard of performance and innovation excellence Boston is known for,” said Dave Jaques, Aftermarket Mobile Audio Product and Marketing Manager for Boston Acoustics. “With the addition of this line, there is now a Boston amplifier perfectly matched to power any Boston speaker model and to meet every customer’s needs. The GTA models offer a small footprint with stunning looks and an aggressive feature set. We’re confident they will redefine high-performance amplifier value.”
Performance Features
Boston GTA amplifiers employ a host of performance-enhancing features not commonly found in amplifiers at their price points. GTA amplifiers are available in both Class AB and Class D designs, as well as a hybrid model. The high-efficiency Class AB models are specifically designed for better sound quality in full-range applications. The Class D models provide optimum power delivery for subwoofer applications, while the hybrid 5-channel amplifier offers the best of both worlds. All models feature adjustable 12dB/octave highpass and 12dB/octave lowpass crossovers. These can be combined in the Class D models for bandpass operation, using the highpass crossover as a subsonic filer. To offer further system “tweaking” power, Boston has incorporated Q-Tune™ bass enhancement in all models, and, in the Class D models, user-adjustable “Q” for each amplifier’s highpass crossover filter to allow the user to optimize the bass from the subwoofer system without overloading.
Because today’s vehicles are full of noisy electronic components that sometimes cause noise interference, Boston’s SST™ (Symmetrical Signal Topology) system uses balanced asymmetrical inputs for noise cancellation to ensure that any noise introduced will be removed from the audio path, not amplified by it.
Installation Features
Boston engineers developed the GTA amplifiers with very specific design goals to ensure that they would fit into as many spaces as possible. Using an extruded aluminum chassis, GTA amps pack a ton of features and power into a compact footprint. Further reducing the overall footprint, Boston’s IMS™ (Integral Mounting System) allows for direct mounting through the amplifier without the need for extended mounting feet or tabs, saving more precious space.
Dedicated High- (speaker level) and Low- (RCA) level inputs with wide-ranging input sensitivity (200mV to 5V for Low, and 400mV to 10V for High) mean that compatibility is extended to the widest possible range of head units, factory adapters, and system preamps. All input/output connections are located on one side of the amplifier, with optimal angled speaker and power blocks for easy wire connections. The recessed control panel permits clean installation with wires concealed. All GTA installation features provide increased flexibility and ease of installation while retaining full use of interior space, which is so critical in today’s smaller vehicles.
Lastly, the GTA-RSL is an optional remote level control that gives the user independent level adjustment, from the comfort of the driver’s seat, of the subwoofer’s output level, beyond the standard system volume control.
