Pan Pot
Gately Electronics' new four-channel PP-4 unit accepts up to four inputs and permits panning these sources anywhere in the stereo output signal. Automatic level compensation is incorporated so that the signal level appears constant regardless of stereo image location. The unit also has a stereo master gain control. Dimensions are 5 1/4" H x 19" W x 7 1/2" D. Noise is under-75 dBm; maximum output is +30 dBm without clipping. Input impedance is 10k ohms unbalanced bridging, and output impedance is 600/150 ohms balanced or unbalanced.
Auto Cassette Player
Sony/Superscope enters the auto cassette machine market with its new Model 20 stereo automobile cassette player. It features a push-in front-loading operation that permits one-hand insertion of cassettes. The cassette is automatically ejected when the end of the tape has been reached, whereupon power to the unit is shut off. The auto cassette machine also features fast-forward and rewind for program search, and tone and volume controls. Incorporating an 18-watt (IHF) dynamic music power output, the company states that the Model 20 is the most powerful auto tape unit available.
Power requirements are 12 volts ( auto battery, positive or negative ground). . Signal-to-noise ratio is 45 dB; wow and flutter, 0.28% 1 7/8 ips; outputs, two extension speakers (impedance for each channel is 3.2 ohms). Dimensions are 2 7/8" H x 7-3/16" W x 81/4 D. Price is under $119.50, complete with car mounting bracket and hardware, head-cleaning device, and a coupon for purchase of a 3-pack of prerecorded Superscope cassette albums at a special introductory price of $8.85.
New Elac/Miracord Turntable
Benjamin Electronic Sound has introduced the Model 750 automatic turntable, at $139.50. It is said to be identical to the Miracord 50H ($159.50) except that the Model 750 has a special four-pole induction motor instead of a Papst hysteresis synchronous motor, and has different trim. Thus, it retains pushbutton controls, a 12-in. one-piece die-cast turntable platter, and silicone-damped cueing.
