Hertz ML Power 4, four-channel power amplifier
 
Hertz Mille Power is redefining Class D amplification. With new hyper-efficient chassis design, the compact case size belies the brutish power available inside. Balanced high -level inputs ensure noise is kept to a minimum. This four-channel specimen can be run in four, three or two channel mode and is 2 Ohm stable. Bypass, Hi Pass and Lo Pass filters are all included.
