About the Delta Mono
The Classé Audio Delta Mono is a high-output, solid-state monaural power amplifier designed to drive demanding loudspeakers. It uses a Class A/AB output stage, operating in pure Class A for the first 35 W into 8 ohms and transitioning to Class AB for higher power. Each amplifier is a separate monoblock with balanced and single-ended inputs, substantial power-supply capacity, and compatibility with speaker loads down to 2 ohms. The manufacturer’s product page and owner’s manual provide the technical specifications listed below.
