Legacy Series - AP6040

2x 2000w @ 4 Ohms Amplifier

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.
