Audio Wave CR 401 Dual Mono Class AB Amplifier

A true dual-mono design like the CR-401 features two entirely independent amplifier circuits, each with its own power supply, within one chassis. This eliminates "crosstalk" (signal bleeding between channels), resulting in superior stereo separation and a much more precise, holographic soundstage.

Magnetic distortion is a hidden enemy in high-fidelity audio. Takman OFC resistors are non-magnetic, ensuring that the signal path is not influenced by stray magnetic fields. This results in a cleaner, more natural mid-range and treble response compared to standard industrial-grade resistors.

Yes. The Direct Input bypasses the internal Op-Amp stage, sending the signal straight to the power amp section. This provides the shortest possible signal path, raising the Signal-to-Noise ratio to a staggering 120dB for the purest possible audio reproduction when using high-voltage sources.

The CR-401 utilizes machined copper nickel-plated heatsink rods and an aircraft-grade aluminum chassis. Copper is significantly more efficient at thermal transfer than aluminum alone, allowing this high-bias Class AB beast to maintain optimal operating temperatures even during extended listening sessions.

Standard PCBs use 1-ounce copper. By using 3-ounce gold-plated boards, Audio Wave reduces internal resistance and increases current capacity. This allows for instantaneous power delivery to your speakers, resulting in tighter, more controlled bass and lightning-fast transients.

While the CR-401 is primarily designed as a world-class stereo amplifier for mids and highs, it is bridgeable to 800W RMS at 4 Ohms. Its high-current design makes it more than capable of driving ultra-high-end subwoofers with incredible musicality.

At full tilt into 2 Ohms, the CR-401 can pull upwards of 120 Amps. For a product of this caliber, we recommend a high-output alternator and dedicated lithium or high-quality AGM batteries to ensure the rails never sag, preserving the amplifier's massive dynamic headroom.

Alps Blue Velvet potentiometers are legendary in the high-end home audio world for their exceptional channel tracking and longevity. They ensure that both the left and right channels stay perfectly balanced at all volume levels, preventing the "tilting" of the soundstage common in cheaper amplifiers.
