Turn On Options Switch

For convenience, there are three ways the Model 275 v.2 can be turned on and off:

•Manually, by pressing the Power button on the front panel.

•Automatically by Audio, when an audio signal is present at the audio Input jacks.

•Automatically by 12V, when a suitable trigger voltage is applied to the 12V input jack.

Note: When either automatic turn on option is selected the front panel Power button is disabled so that power on/off is determined solely by the triggering preamp, receiver or active audio signal. Pushing the Power button will not turn the amp on or off.

Manual Position

When the Turn On Options switch is in its Manual position the Model 275 v.2 must be turned on and off manually by pressing the Power button on its front panel every time you wish to use your audio system.

Audio Position (Automatic on/off)

When the Turn On Options switch is set to one of the two Audio positions, the Model 275 v.2 will be turned on only when an audio signal is present at the L or R Input jacks. After the audio signals cease the Model 275 v.2 will remain on for about 8-10 minutes before shutting off. This prevents unintended turn-off during pauses in your music or movies.

Note: When the Turn On Options switch is set to Audio the Model 275 v.2 will turn itself on immediately when you connect its AC cord, even without any audio signal present. This is normal and another reason why all connections and settings should be made before connecting its AC cord.

Quieter: This is the more sensitive setting and the amp will turn on automatically with a very low level audio signal corresponding to about 1mV. In most cases this will be the preferred setting. If for some reason the amp never turns off you may have some noise in your system that is false triggering the automatic turn on circuit. In this case you should use the Louder setting.

Note: If you need the Model 275 v.2 to turn on at an even lower volume level, simply turn down its L and R Level controls. Try setting the level controls at 12 o’clock and see if the volume level is low enough when the amp turns on.

Louder: This is the less sensitive setting and the amp will turn on automatically with a slightly higher level audio signal corresponding to about 6mV. You should first try the Quieter setting. If for some reason the amp never turns off when set to Quieter then you can use the Louder setting.

Note: If the Model 275 v.2 is driving only passive subwoofer(s), surround or rear channels you will achieve more consistent automatic turn on by using the 12V DC trigger. At the beginning of most films the sub and surround levels are often lower than the minimum level required by the Audio sensing circuit.

12V Position (Automatic on/off)

When the Turn On Options switch is set to its 12V position, the Model 275 v.2 is turned on and off only with an external +9 V to +12 V voltage from your preamp or AV Receiver. When the external voltage ceases the Model 275 v.2 will turn off within a few seconds. The 12V switch position disables the front panel Power button.
