The Delta PRE is the foundation of your perfect system. Designed to connect to a range of sources, the PRE will exact the highest performance from every recording, whether analog or digital. Classé Delta PRE is a one-box stereo pre-amplifier/DAC featuring USB A/B inputs, Ethernet, AES/EBU, Coax, Optical, Balanced and Single-ended analogue, plus a built-in MM/MC Phono stage.It also features subwoofer output(s) w/gain and phase control, a 5-band parametric EQ per channel, and Tone Controls with Tilt and adj. Freq.

There's also a 4 x 1 HDMI switching module available to accommodate systems with AV sources.

The Delta PRE uses touchscreen control that enables a high degree of customization which according to the company, remains intuitive and straightforward for everyday use. Control apps for iOS and Android devices and IP control also provide ease and flexibility of operation from the listening chair.
