High-Resolution Audio for uncompromised sound
Experience digital music to the fullest with High-Resolution Audio. By capturing music at a higher rate than CD, increasing both audio samples per second and the bit-rate accuracy of each sample, High-Resolution Audio offers an uncompromised rendition of an artist’s music. Savour every breath and subtle movement for a truly emotional experience.
Ultra-wide frequency response for full-range sound
The XM-GS4's wideband frequency range—ranging from 10Hz to 100kHz—is designed for today's broad variety of music styles. The lower end of the frequency range offers more than enough latitude for even the deepest sub-bass notes. At the high-end, you'll be able to feel subtle sub-harmonies, giving your music more life and realism.
4 channels create a versatile sound stage
With a 70 W x 4 RMS power output, this 4-channel stereo amplifier gives you a broader range of options as to how you set up your in-car sound. Using bi-amplification, you can separate bass frequencies from highs or ultra-highs, eliminating distortion that occurs when they play through the same channel. You can also independently adjust the volume of different frequencies to find the perfect balance for each song.
Schottky-barrier diodes for smooth, stable sound
Conventional diodes have a voltage drop of between 0.6 and 1.7 v, whilst Schottky-barrier diodes tend to have a maximum drop of 0.45 v. This means that they can deliver faster switching and high-efficiency operation, so you'll enjoy consistently stable power without noise from internal interference.
MOS FET transistor for efficient power delivery
The metal-oxide-semiconductor field-effect transistor (MOS FET) is engineered to deliver a high output from a low-current input. This allows it to provide power to the amplifier's circuits quickly and efficiently, for more responsive operation.
Dedicated control section for fine-tuned audio
The amplifier's control section, located just under the external cover, provides users with the ability to manually adjust aspects of their in-car sound—including resistance and the level of power flowing through each individual component. The XM-GS4's carefully selected components are highly reliable and noise-resistant, minimizing unwanted distortion. The twisted wire structures help to further cancel in-car noise, providing a cleaner overall sound.
Aluminum case absorbs external vibrations
The heavy duty, heat sink integrated aluminum body of this amplifier is designed to prevent external vibrations, for jitter-free sound that stays true to the source.
