The most powerful Yorkville amplifier ever built. The three rack space AP6020 and AP6040 solve the problem of not having cost effective and practically configured power for subwoofers. With better than 2000W per channel (AP6020 @ 2 Ohms, AP6040 @ 4 Ohms), the AP6020 & AP6040 put plenty of clean power just where you need it. The incorporated ?soft turn-on? circuit eliminates nuisance breaker-tripping on power-up while internal protection protects against DC output, thermal overload and inappropriate loads. The user defeatable limiter also prevents audible clipping.

Features:

Designed for rock solid performance right down to and below their lowest impedance ratings
Will easily drive reactive phase shifted loads
Advanced protection schemes including DC current, load, thermal and breaker protection
User-defeatable peak limiter that is transparent below clipping levels
'Soft turn-on' circuit eliminates damage to attached components and prevents nuisance breaker-tripping
Computer-optimized Silentfantm front-to-back heat dissipation system
Long-life, faceplate-mounted, user serviceable, air intake filters
Front panel Power, Protect, Activity and Clip LED's
Speakontm and binding post outputs
Balanced XLR & 1/4" TRS inputs
Impedance Mode switch (AP800 & AP2020)
Sturdy all-steel construction
Baked-on, black finish
