of external C, R. Uses either oscillator at the time of stereo
operation. Capable of also resetting manually.
Capable of constant-current driving low-order 7 dots (green
LED). Constant-current value variable with an external
resistor
Lower current drain available by connecting green LEDs in
series
Built-in input amplifier
Requires no other light-up level adjustment than adjustment
for 0 dB. D1 error: within ±3 dB of 20 dB
Supply voltage range : 10 to 16 V
