Frequently Asked Questions
-
This amplifier delivers 100 watts times 4 channels plus 250 watts times 2 channels at 2 ohms with less than or equal to 1% total harmonic distortion plus noise (THD+N). It also supports bridged modes with 200 watts times 2 plus 500 watts times 1 at 4 ohms under the same distortion specifications.
-
It features a Class D amplifier circuit, which is known for higher efficiency, lower heat generation, and compact design, providing powerful audio output suitable for high-resolution audio playback.
-
The amplifier has a very low total harmonic distortion plus noise (THD+N) of less than or equal to 0.03% at 10 watts into 4 ohms and a signal-to-noise ratio greater than 85 decibels, ensuring clear and distortion-free audio performance.
-
The frequency response spans from 10 Hz to 45 kHz (0/-3 dB), supporting a wide audio spectrum including high-resolution audio signals, ensuring detailed and dynamic sound reproduction.
-
The damping factor is greater than 500, which helps maintain tight control over speaker cones, reducing distortion and improving bass response for enhanced audio fidelity.
