Continuously Adjustable Audio Delay Lines series: GADL-47 Application: @ Continuously variable delay for audio analog signals. @ Variable speech control of playback. @ Voice control of tape recorders. @ Voice scrambling systems. g Telephone time compression. m Chorus effect, tremolo, vibrato. @ Stage echo effect. m= Sound effect. Features: a Unit completely designed. (no external components required). = Up to 100MS continuous delay adjustment. w Clean output signal. w Covers full audio range. (100 MS) Specifications: DELAY VARIATION: Delay can vary between 250us to 100 Ms. Delay change is given by the formula TD = 1024/FCK. The minimum clock frequency (FCK) shall be 10 times the highest analog frequency to pass through the delay line. ANALOG SIGNAL: @ Frequency response: 0 to 500 Khz. (see table). @ Input voltage: 2mV to 1V p-p Max. @ Gain: 5 typical. @ Input impedance: 40K 0 typical. m Output impedance: 75 0 typical. @ Signal-to-Noise ratio: 70 db dynamic range typical. m Distortion: 1% or lower. CLOCK FREQUENCY: (FCK): @ Range: up to 6 Mhz. m CMOS compatible circuits POWER REQUIREMENTS: @ +15 Vdc; 50 ma. typical. @ 15 Vdc; 20 ma. typical. TEMPERATURE RANGE: w@ Operating: 0 to 70C.
