MA2275 2-Channel Integrated Amplifier

MA2275 combines classic McIntosh 75 watt per stereo channel power amplifier with for the first time a low noise tube preamplifier on one convenient polished stainless steel chassis. Twin McIntosh Blue wattmeter mounted on classis glass faceplate, with both rotary function and wireless handheld remote control options, duplicates that of separate components. Six inputs sources and one tape loop allow flexible source connection options. Preamplifier outputs allow use with additional amplifiers or signal processors.
