- Independent variable 0-10 dB 40Hz bass boost provides additional bass response at lower frequencies for both front and rear channels.
Footnotes
- CEA-2006 Compliant — Standardized “Voluntary” Testing & Measurement Methods for Mobile Audio Amplifiers. This standard advocates a uniform method for determining an amplifier’s RMS power and signal-to-noise ratio. Using 14.4 volts, RMS watts are measured into a 4-ohm impedance load at 1 percent Total Harmonic Distortion (THD) plus noise, at a frequency range (for general purpose amplifiers) of 20 Hz to 20,000 Hz.
