McIntosh engineers could not be content with another preamplifier New concepts, new technology has produced a preamplifier that gives you flexibility. Look at the great number of ways you can enjoy the C 29 C 29 DIVERSIFIED FLEXIBILITY 1. YOU CHOOSE FROM EIGHT DIFFERENT PROGRAM SOURCES The input switch selects from six different sources or you can choose to listen to either of two tape recorders at the push of a button. 2. PRECISION STEP ATTENUATOR VOLUME CONTROL Ideal volume tracking accuracy and noise free performance are two of the considerable benefits of the McIntosh Precision Step At- tenuator. It is a thirty-two step, 70 dB range con- trol with unheard of tracking accuracy within 1 dB. The extreme accuracy is obtained through special electronically controlled resistance ele- ment trimming. The accuracy and quiet operation are maintained because the switch commutator touches only the switch contact pad and not the precision resistor elements. 3. AUTO TURN ON/TURN OFF Power to the entire stereo system can be controll- ed from either the front panel power switch or the turntable's power switch. A current sensing connected to the turntable AC power outlets is controlled by the turntable power switch. The relay, in turn, controls the AC power to the mainder of the system. 4. STEPPED TONE CONTROLS INDEPENDENT IN EACH CHANNEL Settings are precise and repeatable in each chan- nel, independently. Each tone control is a separate eleven position switch concentrically mounted. Each step is connected to carefully selected resistors and capacitors to give the precise frequency curve shape. Because the tone circuit component parts are not in contact with the switch surfaces, as in ordinary continuously variable rotary controls, they never change, never get noisy and provide exact, repeatability set- tings. 5. YOU ALWAYS GET THE IDEAL STEREO IMAGE The McIntosh seven position mode has facilities to permit the correct of a

stereo system to maximize stereo imaging. 6. YOU CAN LISTEN AT LOW VOLUMES WITH EQUAL PLEASURE A continuously loudness control lets you enjoy full frequency response and warmth of music regardless of the room volume you choose. As volume is reduced, the frequency response is adjusted to complement the human ear response characteristics, the Fletcher effect. 7. TAPE RECORDING AND PLAYBACK MADE EASY Tape input, tape output and switching facilitiesare provided for two three-head tape recorders. Simply push a button to listen to either one - - or record from any selected source on either or both - - or - - copy from one tape recorder to another while listening to an entirely different program. You can instantaneously monitor either tape recorder. 8. STEREO MICROPHONE INPUT MAKES RECORDING EASY Microphones in stereo may be used with the C 29. By tuning the input selector to MIC the microphone set-up will be connected to either one or both of the two tape recorders connected to your system. 9. THE CONSTANT LOUDNESS BALANCE CONTROL The McIntosh balance control adjusts each chan- nel independently for stereo imaging without changing overall stereo volume in the room. While natural balance is at the center of the control; ad- to either right or left compensates for program variations or room acoustic differences. 10. LISTEN TO YOUR QUIET RECORDS, QUIETLY Any unwanted noise (hiss, rumble, fry, etc.) can be reduced with the filter switch. It allows the reduc- tion of low frequency noise and high frequency noises (below 50 Hz and above 7 kHz). 11. CONTROL REMOTE LOUDSPEAKERS FROM YOUR PREAMPLIFIER Through a unique McIntosh design, you haveON/OFF control of two separate sets of stereospeakers when used with an accessory switching relay (the McIntosh SCR 2).
