5. 1 Description of function

The two red LEDs (10 and 11) signal that the output relay of the output stage channel is open and that means that

the transmission of a music signal to the connected loudspeaker is interrupted.

The blue LED 12 in the middle signals that the unit is switched on (operational status).

To connect the unit to the mains socket, please press the mains power switch 13 on the front of the unit. To start

your listing music please check, if the MUTE switch 9 on the rear isn't activated.

After switching on the mains switch 13 all three LEDs will turn on. After approx. 5 seconds the two red ones will

extinguish, while the blue LED stays on showing that the unit is running.

5. 2 Operating instructions

▪ Switching on: Always switch-on the power amplifier last, i.e. after the other devices in your system

(preamplifier, CD player, etc).

▪ Switching off: Always switch-off the power amplifier first and then switch-off the other devices from the

mains power.

▪ When you switch off the unit from the front panel the auxiliary transformer remains connected to the mains

power. The power consumption is minimal. However, for longer periods of absence always disconnect the

power amplifier from the mains power by pulling the mains plug from the socket.

▪ During a thunderstorm please completely disconnect the unit from the mains power by pulling out all three

plugs.

▪ Avoid unnecessarily frequent switching the power amplifier on and off. The high amount of switch-on current is

a heavy burden for the electrical components and so the life of the unit will be shortened by this action.
