From McIntosh:

The McIntosh C28 is a high quality stereo pre-amplifier.

Each channel of the C28 consists of four parts, a low level amplifier, high level amplifier, active filters and headphone amplifier.

Common regulated power supplies furnish power to both channels.

New records and tapes with greatly increased dynamic range demanded new low noise circuits. McIntosh scientists developed a new DIFFERENTIAL INPUT CIRCUIT that reduced phono input noise levels from approximately 2.4 microvolts in an excellent preamplifier to a new level of only 1.2 microvolts! The differential circuit has only been used in very sensitive professional test equipment and in medico-electronics. The (C-28) preamplifier will not overload or change distortion for any phono input signal from 2 millivolts up to 500 millivolts. This represents a dynamic range of approximately 3000 to 1 on a voltage basis. This fantastic improvement necessitated extreme care in layout and manufacturing. The signal circuits need careful shielding and wiring with coaxial cable to prevent noise and crosstalk in the preamplifier from destroying the low noise advantages of the circuit.
