Manufacturer:SANKEN Description:VOX output The VOX detection signal is output from this pin. This pin should be connected through a resistor (100-200kΩ) to the power supply. VOX detection control This pin should be connected through a resistor (10 to 470kΩ) and a capacitor in parallel to the ground. The resistance determines the sensitivity of VOX detection. Internal reference supply voltage output This pin should be grounded through a 100µF capacitor. Equalizer amplifier output Amplified play signals from the head are output from this pin. A resistor and capacitors connected between this pin and Pin14 determine the equalizer characteristics. Equalizer amplifier inverse input This pin connects through a resistor to Pin13 to determine the equalizer characteristics. The expect- ed input impedance is typically 10kΩ. To the REC/PLAY head A REC/PLAY head must be connected between this pin and the ground. Switching of REC and PLAY modes is done by Pin9. A load resistor should be connected between this pin and the ground because the input impedance becomes high (several hundred kilohms) in the PLAY mode. REC gain control A resistance connected between this pin and the ground determines the head bias current in the REC mode. The lower the resistance, the higher the current. A serial combination of a resistance and a capacitance, connected in parallel with the resistance, determines the REC gain. VOX amplifier input The preamplifier output at Pin18 must be connected through a resistor and a capacitor to this pin. The impedance between Pin18 and this pin determines the gain, and a resistance betweeen Pin11 and the ground determines the frequency characteristics of the VOX amplifier. Preamplifier output Amplified MIC/line preamplifier outputs are output from this pin depending on the the statuses of Pin7 (preamplifier mute) and Pin8 (MIC/line switching). Preamplifier inverse input Resistors and a capacitor connected between this pin and Pin18 and 12 determine the preamplifier gain. The input impedance at this pin is several hundred kilohms. ALC detection control A 240kΩ resistor and a 4.7µF capacitor connected in parallel between this pin and the ground control ALC detection sensitivity. |
