[. . . ] C 504 BEST COMPACT PREAMPLIFIER! When you need a reliable, tow noise flexible preamplifier in a compact size, you need the Mclntosh C 504. SUPERIOR PERFORMANCE The Mclntosh C 504 is a high technology preamplifier in a compact new case size. [. . . ] FET ANALOG INPUT SWITCHING All critical input switching is done electronically using field effect transistor analog switches. The front panel selector simply switches small amounts of control DC voltage which turn the FET analog switches on or off. Since the FET analog switches are located near the input jacks, the length of interconnecting leads is much shorter. TRI-FREQUENCY PROGRAM EQUALIZER Three separate controls allow the balance and response of musical information to be adjusted with far more flexibilty than with conventional tone controls. Use of the program equalizer controls does not affect in the slightest, the low noise, low distortion performance of the preamplifier. When the equalizer controls are in their center or flat detent position, their action is neutral and response of the preamplifier is absolutely flat. HEADPHONE/OUTPUT AMPLIFIER The main output amplifier section of the preamplifier is a push-pull complementary class AB circuit. Because of the extremely low distortion and power capability of this circuit it is used for both main and headphone outputs. INTEGRATED CIRCUIT OPERATIONAL AMPLIFIERS Both the magnetic phono and the equalizer amplifier stages utilize new high technology integrated circuit operational amplifiers. Noise factors are incrediably low, and distortion levels are at or below the limits of present day test equipment. shown in optional walnut veneer cabinet C 504 Performance Limits PERFORMANCE GUARANTEE Performance limits are the maximum deviation from perfection permitted for a Mclntosh instrument.
