The AP2020 weighs a comfortable but solid 35 pounds, fits into two rack spaces, and has the best distortion and noise specifications you will find anywhere. Unique 2 or 4 Ohm optimum load operation gives the AP2020 amp flexible output power as required. A simple user definable configuration allows it to deliver 600 Watts per channel continuous average into either 2 or 4 Ohms.

AudioPro amplifiers feature advanced protection schemes including DC current, load, thermal and breaker protection as well as a user-defeatable peak limiter that is transparent below clipping levels. A 'soft turn-on' circuit eliminates damage to attached components and prevents nuisance breaker-tripping. The computer-optimized (Silentfan) front-to-back heat dissipation system incorporates ultra-quiet, variable-speed internal fans and are designed to ensure that excessive thermal stress will not occur. For ease of maintenance and to ensure efficient cooling, the amplifiers are supplied with long-life, faceplate-mounted, user serviceable, air intake filters. Front panel Power, Protect, Activity and Clip LED's are bright and easy to see and all knobs and handles are recessed for safe, easy transportation.

The internal signal path has been optimized and a toroidal transformer is used - both of which serve to reduce hum and noise while keeping weight to a minimum. The two-tier power conversion of the AudioPro AP-Series amplifiers approaches efficiency levels normally associated with switching power supply technology; yet provide the superior transient response and low distortion of the best analog designs. Inside an AP4020 AudioPro amplifier designs, while unique, are conservative with regard to the power handling capabilities of the output devices. To further assure trouble-free operation, all AudioPro amplifiers undergo a thorough computer-monitored, temperature-cycled, burn-in period to test for any deviation from design parameters.

The back panel features Speakon and binding post outputs as well as balanced XLR & 1/4" TRS inputs. The peak limiter, subsonic filter, mono/stereo/bridge mode and ground lift switches are also mounted on the back panel. The unique Yorkville Impedance Mode switch (AP1020 & AP2020), also located on the back panel, allows the user to select full output power into two or four ohms for maximum application flexibility
