Wait until the tube test counter is displayed as 000sec (approx 160 seconds later). Then, please proceed to the

11、Tube calibration test. EMX-1/ESX-1 Tube Calibration Connect the stereo plug of the cable (see fig.) to PHONES and the monaural plug to INPUT. 2. While pressing ERACE and STEP EDIT, turn the power on. “Valv Wup” is indicated as stand-by for pre-heating, and also the waiting time is indicated. Set up

12、the volume knob and switches as follows: MASTER VOLUME : MAX TUBE GAIN : MIN AUDIO IN LEVEL : MAX MIC/LINE : MIC 3. “Ajst (L)” and a 4 digits figure are indicated in the LCD. If the value is leas than 0010, the test is O.K. Press the 16 knob at the right bottom. If the value is over it, it is requir

13、ed to adjust the valve. Adjust the variable resistors which correspond to the channels referring to the photo below. 4. As well asAjst(L)”, “Ajst (R)” and a 4 digits figure are indicated in the LCD. If the value is leas than 0010, the test is O.K. Press the 16 knob at the right bottom. If the value

14、is over it, it is required to adjust the valve. Adjust the variable resistors which correspond to the channels referring to the photo above. 5. Once the balance of L/R is automatically adjusted, “ValvGMax GainMx” is indicated in the LCD. Turn the TUBE GAIN knob to MAX, and press the 16 knob. 6. Chec
