The McIntosh C32 preamplifier provides the most comprehensive range of functions and control options. The C32 is a dual stereo preamplifier with a built-in monitor power amplifier. There are two totally independent left and right stereo program lines running through the preamplifier. One program line is the listen program line. the other is the record program line. Each program line can select its own program source from any connected input signal i.e. phono, tuner, aux or tapes 1, 2 or 3 without interference with the other program line.
