Description of TURN-ON Sequence

OPERATION

When turning on the system, the amplifier should always be last.

The KSAOn/Off switch is part of a multi-level turn-on circuit that goes

through several steps of protection. Upon turn-on, the amplifier's outputs

are not connected to the speakers. After the protection circuits have

determined that the unit has completely stabilized, the speaker relays will engage. You will hear a click at this point. The LED's in the bias meter will start at the highest bias level upon turn-on and slowly work their way down to no-bias. This process takes approximately 1 minute. The amplifier is ready to use once the bias meters have settled to the no-bias level.

1.Push the black Power button on the amplifier front panel to turn it on. The Power button is the larger of the two buttons at the top of the face plate. The blue LEDlabeled POWERin the center of the bias meter will illuminate when the Power button is depressed. The amplifier will progress through the turn-on sequence described above.

2.With the preamplifier in the Mute position, or volume control fully

attenuated, select a source. Turn the volume control up to your desired listening level.

3.Enjoy.
