Its preamp section uses two 12AX7A and two 12AT7 tubes, while the output stage delivers 200 Wpc into 8 ohms or 320 Wpc into 4 ohms, giving the MA352 the power to drive a wide range of loudspeakers.\u003c\/p\u003e\n\u003cp\u003eSix analog inputs include two balanced, three unbalanced, and one Moving Magnet phono input with adjustable loading. A stereo preamp output allows the MA352 to feed an external power amplifier or connect one or two powered subwoofers, while Home Theater PassThru makes it easier to incorporate the amplifier into a multichannel system.\u003c\/p\u003e\n\u003cp\u003eA five-band analog equalizer provides ±12 dB of adjustment at each frequency band, with tone bypass available when no correction is required. McIntosh High Drive headphone circuitry with Headphone Crossfeed Director is also included for private listening.\u003c\/p\u003e\n\u003cp\u003eThe MA352 incorporates McIntosh Power Guard to monitor the output signal and help prevent clipping, along with Sentry Monitor protection and Monogrammed Heatsinks connected to the high-current output transistors. Dual-scale blue watt meters provide power-output indication for both 4- and 8-ohm loudspeaker loads.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003ch4\u003eHybrid Drive Design\u003c\/h4\u003e\n\u003cp\u003eThe MA352 pairs a vacuum tube preamplifier with a solid-state power amplifier.
