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 70W 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 1.7v, whilst Schottky-barrier diodes tend to have a maximum drop of 0.45v. 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, minimising unwanted distortion. The twisted wire structures help to further cancel in-car noise, providing a cleaner overall sound.
Aluminium case absorbs external vibrations
The heavy duty, heat sink integrated aluminium body of this amplifier is designed to prevent external vibrations, for jitter-free sound that stays true to the source.
