8Mute Button

Toggles between normal output level and the user-programmable mute function, reducing the level by -10 to -73.2 decibels (de- pending on the user’s programming). The factory default setting gives a 20 decibel reduction in output.

If the volume is adjusted while mute is engaged, the volume will begin changing from the muted level, and mute will be automati- cally disengaged. This approach avoids the problem of turning the volume up, only to then “unmute” the system without thinking and suddenly find it dangerously loud.

9Balance Button

Duplicates the function of the balance button on the front panel of the Nº383 Controller, allowing you to then fine-tune the rela- tive balance of the Left and Right channels from your listening po- sition using the volume buttons, in 0.1 dB increments.

10Polarity Button

Inverts the polarity (sometimes inaccurately called “absolute

phase”) of the outputs of the Nº383, indicated by the LED on the

 

front panel. A second press of this button will restore the outputs

 

to their original, non-inverting polarity.

11Battery Compartment (on bottom of remote control)

Using a #3 (small) Philips screwdriver, remove the bottom plate to access the battery compartment when it becomes necessary to re- place batteries. The Nº383 remote control uses two alkaline AAA batteries.
