The powerful AP4020/AP4040 weigh a comfortable but solid 40/43 lbs. and occupy only two rack spaces. They deliver 1200 Watts per channel (AP4020 @ 2 Ohms, AP4040 @ 4 Ohms). The AP4020/4040 power amplifiers also incorporate a ‘soft turn-on’ circuit which eliminates nuisance breaker-tripping on power-up.
