HDMI ARC Input: Brings TV sound directly to your audio system with the convenience of using your TV’s remote to control volume and power.

High-Resolution Audio from Your PC: USB Connectivity

For those who prefer to stream high-resolution audio directly from their computer, the QUAD 3 features a dedicated USB-B input that supports hi-res playback up to 768kHz PCM and DSD512 formats. This makes it an ideal solution for audiophiles who rely on their PC or laptop as a primary source for digital music. With plug-and-play functionality, the QUAD 3 effortlessly transforms your computer into a high-end digital audio source, delivering pristine sound quality and unlocking the full potential of high-resolution music files. Whether you’re using streaming platforms, local files, or advanced playback software, the QUAD 3 ensures every detail is captured and reproduced with breathtaking clarity.

Upsampling

Upsampling can be applied to the audio from both SPDIF and USB audio sources. The digital audio is upsampled to either 352.8kHz or 384kHz.

Power and Precision at Your Fingertips

Despite its modest footprint, the QUAD 3 is a compact powerhouse. The Class AB Amplification stage is equipped with a custom engineered power supply.

A robust 235VA toroidal transformer feeds the amplifier, supported by a 30,000uF reservoir to ensure dynamic headroom and low distortion. Rated at 65W per channel (8 ohms) and peaking at 100W (4 ohms), the QUAD 3 effortlessly drives demanding loudspeakers with control and authority- in proper QUAD form!

Signature QUAD Touches

The QUAD 22 influences can be seen in the subtle accents of the facia, and neat row of digital encoders. These tactile rotary controllers provide volume control, source selection, bass control, QUAD ‘tilt’ control and balance adjustment. The bass adjust allows +/-3dB adjustment of the low-end frequencies, adding richness and depth or removing rumble according to your components, system or room. But the ‘Tilt’ control differs by adjusting both ends of the frequency spectrum together, either attenuating the bass and lifting the treble or lifting the bass and attenuating the treble in 1dB steps. ‘Tilting’ the audible frequency range on a 700Hz axis, thereby adjusting the overall sound balance to make it either 'warmer' or 'cooler' to suit the recording and/or the room acoustics.
