„ Dummy load

DC14.4V(11 to 16V)

20K Ω (2 Speakers connection)

Line out 2.5V (Vol. MAX)

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.

„ How to connect the extension cable for adjusting

Caution:

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.
