Mains power connection

Connect the low voltage plug from the power supply to the 2x48V= socket of the amplifier before
connecting the power supply to the mains.

To switch on from standby or to standby

The switch on the left hand side of the front panel turns the unit on or back into standby. The blue LED above
the stand-by switch shows that the unit is switched on.

After switching on, the tubes need a short time to reach the correct operating temperature. During
warm up the blue LED above the stand-by switch is blinking.
We recommend to set the pre amplifies volume control to 0, prior to switching on.
