That is, the volume of this signal is controlled by the external processor or preamp and not by this amplifier.
- Page 7 5. 7 Correct phase for the loudspeakers The terminals on your amplifier and your loudspeaker are colour coded or marked with a plus (+) and minus (-). Connect the red (+) output terminal of your amplifier with the red (+) input terminal of your loudspeaker.
- Page 8 IMPORTANT! Switching on: Always switch on the power amplifier last, i.e. after the other devices in your system (preamplifier, CD player, etc). IMPORTANT! Switching off: Always switch off the power amplifier first and then switch off the other devices from the mains power. IMPORTANT! After switching the unit off please wait 30 seconds before switching it on again.

- Page 10 By holding down the right rotary control, the countdown counter counts from 8 to 0, whereby the volume is continuously increased until the switch is made from "U0" to "U1". If you release the rotary knob within the count down cycle, the unity gain setting is canceled. If the display shows "U1", the volume control for the previously selected input is bridged.
