ASL SECTION
Preset conditions 1. Set VR601 and VR602 around the center of the adjustable range. 2. Ground pins 3 and 16 of IC601. Step Input Output No. (MIC) (Pin 22) Adj.point 1 By using an oscillator, apply a sine Observe the output at VR602 wave of 7Hz/3.6mV to the MIC Pin 22 on a DC V meter terminal (+) via a 600-ohm resistor. (pointer-type). 2 By using an oscillator, apply a sine Observe the output at VR601 wave of 7Hz/64mV to the MIC Pin 22 on a digital terminal (+) via a 600-ohm resistor. multimeter. 3 Repeat Steps 1 and 2 until doth adjustments satisfy the specifications. 4 By using the jig(CAN-906,CAN-912), Observe the output at VR602 apply a sine wave of 7Hz/100dB-SPL Pin 22 on a digital directly to the MIC. multimeter. 5 End To connect the Amp unit and the DSP unit, use Jig GGD1153.
