The A23+ builds on the phenomenal performance of the A23.

Features include circuitry designed by legendary John Curl, upgraded power output, transformer, filter capacitance, internal connections, speaker terminals and cosmetics. High bias Class A/AB operation. Direct Coupled. DC Servo and relay protection circuits. 2 x XLR inputs. 2 x RCA inputs (with loop output). Independent gain controls for each channel. Ground lift controls. Input selector controls (XLR/RCA). Bridged/Stereo switch. Audio sensing on/off (withsensitivity controls). 12V trigger input & output. Power output (Stereo): 160 watts RMS x 2 at 8 Ω. 240 watts RMS x 2 at 4 Ω. Bridged Mode: 400-500 watts at 8 Ω. Heavyduty 24k gold-plated 5-way speaker binding posts. Gold-plated RCA input/output jacks. 2U Chassis, carry handles, rack mountable with HRA2 (sold separately).
