Connect an oscillator to the UN-BALANCED input terminal each of the L-ch and R-ch. Make sure that the frequency is 1kHz, keep

29、the output down and then turn on the oscillator.3. Hold down the SPEAKERS 2 button and UN-BALANCED button at the same time when turning on the unit. (It switches to the Meter Adjustment Mode.)4. Adjust the oscillator output to 1.89 V (rms).5. Adjust the L-ch. The display will indicate the status as

30、shown on the following figure (for one): Press the DISPLAY button once, and the display indicates L on the left once the unit is switched to the adjustment mode. Check the display and adjust the L-ch output level until it indicates 100. The unit has two keys with a variability of plus and minus 50%

31、at a maximum: one varies 5%, the other 1%, at every one push. At first, press the 5% key, adjust the level until the display indicates nearly 100, and then press the 1% key and set the level to 100. When the value is below 100, turn UP (o).
