3. GETTING STARTED
Turn the BIAS-selector switch clockwise to position V1 = BIAS setting for the tube V1. The LED next
to the tube will illuminate, and one of the three BIAS LEDs will illuminate, normally first the Minus
LED, than the OK-LED.
The LED display:
Ecomode LED
Indicating the status of the Ecomode (see chapter 6.4)
Yellow "-" LED
BIAS setting of the selected output tube is too low
Green “OK” LED
BIAS setting of the selected output tube is correct
Yellow "+" LED
BIAS setting of the selected output tube is too high
Red "off" LED
Indicates that the electronic protection has switched off the
amplifier (see chapter 6.2)
After an additional 5 to 10 minutes, respectively the warm up period, the BIAS control LEDs will
change from yellow to green in case the BIAS Measurement Electronic is switched to tube 1 for
example. This indicates the correct BIAS. Check all four tubes and switch OFF the BIAS electronic
during listening. This is the ECO Off position.
If you notice any irregularity (“+” = High BIAS) in the display please refer to chapter 7.3.
