GENERAL DESCRIPTION MAC 1700 The MAC 1700 is a stereo receiver. There are three easy to use top notch stereo components in one small convenient package. A solid state preamplifier, a solid state power amplifier, and an FM MPX stereo tuner are combined to give you the best performance possible. The result is a compact, easy to use stereo instrument. A stereo instrument that brings you the best in all types of stereo listening. A loudness control allows you to listen to music at low listening levels and still hear the full rich sound of music. There is a filter which lets you minimize noise and rumble from program sources. A tape monitor switch lets you monitor recordings in progress. But the prime function of a preamplifier is to reproduce records and tapes with full accuracy and sonic realism. Your MAC 1700 does recreate music from records and tapes with a degree of accuracy thought impossible a few short years ago. Records and tapes are made with the bass frequencies cut and the highs boosted. This allows more musical information to be put on the record or tape. The MAC 1700 reintroduces the bass and the highs following accurate and definite standards. Your records and tapes sound alive and thrilling when you hear them through your MAC 1700. Sixteen silicon planar transistors are used in the preamplifier. Silicon planar transistors are used because of their high thermal stability, low noise, and superior high fre- quency response. POWER AMPLIFIER Your MAC 1700 delivers 40 watts of power with both channels operating. This is 40 watts of steady state power. Your MAC 1700 delivers 40 watts of power hours on end. Distortion at 40 watts is less than ¼ of 1 % at any frequency from 30 to 20,000 cps. These measurements are made by testing sine wave power. A sine wave signal is fed into the amplifier at a voltage sufficient to drive the amplifier at rated power output. Then distortion is measured at full rated power with both channels operating into an impedance of 8 ohms. Distortion must be less than ¼ of 1 % from 30 to 20,000 cps. Only then is your MAC 1700 ready for you. At less than full power distortion becomes so small it can be measured by only the most sophisticated laboratory instruments. Only Mclntosh gives you this kind of performance. The MAC 1700 gives you a 2.5 microvolt FM stereo tuner. This sensitive tuner brings you clear, noise-free reception from distant stations. The tuner section is a superb product of pride of craftsmanship. In a tuner 1

INSTALLATION CONNECTIONS TO YOUR MAC 17OO CONNECTING THE PHONO 1 POSITION for your main record player Connect the "left" channel to the "L" input of PH 1. Connect the "right" channel to the llR" input of PH 1. If your record player has a ground wire connect the ground wire to GND. CONNECTING THE PHONO 2 POSITION Phono 2 position can be used if two record players are used in a system. Connect the "left" channel to the "L" input of PH 2. Connect the "right" channel to the "R" input of PH 2. CONNECTING TAPE PLAYER (no preamplifier in tape player) Use this position only for a tape deck with no electronics. Con- nect the "left" channel to the "L" input of TAPE HD. Connect the "right" channel to the "R" input of TAPE HD. CONNECTING A TAPE RECORDER or TAPE PLAYER with BUILT-IN ELECTRONICS Connect the "left" channel of the tape player or tape recorder to the "L" channel TAPE MONITOR input. Connect the "right" channel of the tape player or tape recorder to the "R" channel TAPE MONITOR input. CONNECTING A TAPE RECORDER WITH THREE HEADS Connect the tape outputs of the MAC 1700 to the high level inputs on the tape recorder. This will make it possible for you to record from the MAC 1 700. Connect the tape recorder outputs to the TAPE MON inputs on the MAC 1 700. Use TAPE MON . . . In for listening to pre-recorded tapes as well as to monitor. CONNECTING A TAPE RECORDER TO RECORD FROM THE MAC 1700 Connect the TAPE OUTPUTS of the MAC 1700 to the high level inputs on the tape recorder. 7

CONNECTING LOUDSPEAKERS TO THE MAC 1700 The "Left" loudspeaker wires are connected to the two center screws on the barrier strip marked "LEFT OUTPUT". The "Right" loudspeaker wires are connected to the two center screws on the barrier strip marked "RIGHT OUTPUT". The MAC 1700 auto- matically matches the impedance. ANTENNA CONNECTIONS A convenient flexible indoor FM dipole (300 ohm) antenna is supplied with the MAC 1 700. This antenna is easy to install. It is suitable for good FM reception in high signal areas. Connect the two leads of the dipole antenna to the two terminals marked "300" on the back panel of the MAC 1 700. The flexibility of the thick flat wire lets you easily locate the dipole behind the equipment. Open the dipole into a "T." Extend the arms as straight as possible. The dipole antenna is somewhat directional. It should be positioned for best reception of the desired stations. IMPORTANT OUTDOOR FM ANTENNA An outdoor FM antenna is recommended. It will give you the best reception under all conditions. In fringe areas, a highly directional antenna used with a rotator will give the finest possible FM reception. Rotate the antenna until it points in the direction of the station or until it receives the best possible signal. 75 OHM ANTENNA An unbalanced 75 ohm FM antenna can be used with the MAC 1700. Use the two terminals marked 75. 8 Keep the dipole away from large metal objects or surfaces. They interfere with the efficiency of the antenna. MUTING (on the rear panel) This control determines the strength of signal necessary for a station to be heard with the tuner in the muting position. The muting threshold is carefully adjusted to optimum at the factory using precision test instrument. Casual adjustment of the muting threshold is not recommended. AC OUTLETS There are two BLACK AC outlets and one RED AC outlet. The power to the black AC outlets is controlled by the front panel switch. Use these outlets for accessories such as a tape re- corder. The red receptacle is on at all times and is used for a turntable or record changer. The turntable is pro- tected by this arrangement. It is nec- essary to turn off the turntable or rec- ord changer by its own AC switch. Connect the AC cord from your record player to the RED outlet.
