Интегральные усилители — McIntosh MAC7200

The MAC7200 is a solid-state two-channel receiver built by McIntosh in Binghamton, New York, that combines a stereo power amplifier, a preamplifier with digital decoding and a built-in AM/FM tuner in one chassis. McIntosh lists it among its integrated amplifiers, next to the MA7200 that shares the same power rating but has no radio section. The tuner receives RDS data and stores 20 presets per band.

Key specs that matter

McIntosh rates the output at 200 W per channel into 2, 4 or 8 ohm, with total harmonic distortion of 0.005%, dynamic headroom of 2 dB and a damping factor above 40. Response is +0, -0.5 dB from 20 Hz to 20 kHz and +0, -3 dB from 10 Hz to 100 kHz. There are 15 inputs in total - one balanced XLR, five unbalanced RCA, separate moving coil and moving magnet phono inputs, two coaxial and two optical digital sockets, a USB port, one MCT socket for a McIntosh SACD/CD transport and one HDMI ARC input for audio only. High-level sensitivity is 0.5 V balanced and 0.25 V unbalanced at 20 kohm, and phono sensitivity is 0.25 mV for MC and 2.5 mV for MM. Signal-to-noise figures are 80 dB for MC, 82 dB for MM, 95 dB for the line stage and 113 dB for the power amp input. The unit measures 44.5 x 19.4 x 47.6 cm and weighs 34.1 kg.

Engineering and use context

Digital sources are handled by the DA2 Digital Audio Module, built around an 8-channel 32-bit/384 kHz DAC in a Quad Balanced arrangement. The USB input accepts PCM from 44.1 to 384 kHz at 32 bits, DSD64 up to DSD512 and DXD at 352.8 and 384 kHz, while the S/PDIF sockets take up to 24-bit/192 kHz. The power stage drives the speakers through output Autoformers, which is why the rating does not change with load, and Power Guard limits clipping. The MC phono input has adjustable loading, the MM input fixed loading. A High Drive headphone amplifier with the Headphone Crossfeed Director, bass and treble controls and a Home Theater PassThru for combining the receiver with a surround processor complete the feature set. The FM section offers 2.2 microvolt usable sensitivity and 38 dB stereo separation. The chassis is a dual-layer build in black painted steel, standby draw is under 0.25 W, and the unit is Roon Tested.

Pairing

With the same power into 2, 4 and 8 ohm, the MAC7200 accepts difficult low-impedance speakers as readily as higher-impedance designs. Both MM and MC turntables connect without an external phono box, television audio arrives over the HDMI ARC socket, and a McIntosh transport uses the MCT link for SACD playback.

Alternatives

The McIntosh MA7200 keeps the same power rating and DA2 module in an integrated amplifier without the tuner.
