Q66II - the versatile workhorse of the new Q series amplifiers delivers 2 x 600W @4Ohms / 2 x 900W @2Ohms and provides flexible drive capability for a huge variety of speaker systems, including Sx300, ZX4, SB122 etc. Switchable LPN(Low-Pass Notch) filter circuitry provides extra tonal fundamental and kick, with protective Low-Cut for using smaller passive 12" or 15" cabinets without additional subwoofers.
