McIntosh MC830 1-ch Monoblock Power Amplifier 300W (8 ohms) with Dual Scale Watt Meter & Direct Coupled Output

The McIntosh MC830 is a solid-state single-channel power amplifier delivering 300 watts into 8 ohms and 480 watts into 4 ohms. A push-pull complementary circuit with a direct-coupled output gives a damping factor above 100 wideband, and total harmonic distortion is held to 0.005% with a signal to noise ratio of 120 dB balanced below rated output. The open-chassis industrial design follows the MC275, MA252 and MA352, with a footprint matching the MA252 at 312 mm wide.

A Dual Scale Watt meter reads output into both 4 and 8 ohm loads on the same dial. Both balanced and unbalanced inputs are provided, along with Power Control ports for switching connected McIntosh components and a user-selectable Auto Off that powers the amplifier down after 30 minutes without signal. Power Guard makes real-time adjustments to prevent harsh clipping, Sentry Monitor provides fuseless short-circuit protection with automatic reset, and patented gold-plated Solid Cinch binding posts secure the speaker cables.

Why Consider the McIntosh MC830

The MC830 brings single-channel McIntosh amplification into a chassis small enough for rooms that cannot take a full-width component, and it is styled to sit beside the C8 preamplifier and the MC275. The direct-coupled output gives a damping factor above 100, considerably higher than the Autoformer-based McIntosh amplifiers, which suits loudspeakers that reward tight bass control. A pair covers a stereo system, and additional units extend the same amplification across a home theatre front stage.

Ideal For

• Stereo systems using a pair of single-channel amplifiers
• Rooms where a full-width component will not fit
• Systems built around the McIntosh C8 preamplifier
• Loudspeakers benefiting from a high damping factor
• Home theatre front stages needing matched channels
