Balance and Bass &Treble volume : lndication"0"
Loudness : OFF
Standard volume position
Test instruments required for adjustment
Be sure to attach the heat sink and rear bracket onto the power amplifier IC and regulator IC respectively, before supply the
power.
If voltage is applied without attaching these parts, the power amplifier IC and regulator IC will be destroyed by heat.
How to connect the extension cable for adjusting
Power supply voltage DC14.4V(10.5 to 16V)
Load impedance 20K ohm (2 Speakers connection)
Output Level Line out 2.5V (Vol. MAX)
Standard measuring conditions
Exclusive dummy load should be used for AM,and FM. For FM
dummy load,there is a loss of 6dB between SSG output and
antenna input.The loss of 6dB need not be considered since
direct reading of figures are applied in this working standard.
