You can adjust the brightness of the Front Panel Display. The following selections are available:

Normal (default) – The Front Panel Display will operate at full brightness.

Dim – The Front Panel Display brightness will be dimmed.

You can also quickly adjust the Screen Dimmer setting by pressing the DIMMER button on the remote control. Each
press of the button moves to the next Screen Dimmer selection.

Mute Operation

When using the HA-1 as both a headphone amplifier and a pre-amplifier, it may be desirable to mute the Pre-amplifier
Output while listening to headphones. For example, if the HA-1 is connected to a pair of active speakers, it may be
easier to mute the Pre-Amplifier Output than to turn off both speakers when you want to listen with headphones. The
Mute Operation setting is designed for this type of usage. It controls how the MUTE button on the remote control
functions. The following selections are available:

Mute All (default) – Both the Headphone Jack and Pre-amplifier Output are muted when the MUTE button
is pressed. This condition is indicated by a Mute icon on the Front Panel Display. Mute is cancelled if the
MUTE button is pressed again, or if the Volume Knob is turned.

Mute Pre Out – Only the Pre-amplifier Output is muted when the MUTE button is pressed. This is indicated
by the word "MUTE" displayed next to the volume level on the Front Panel Display. Mute is cancelled if the
MUTE button is pressed again. Adjusting the Volume Knob does not cancel mute so that headphone
volume can still be adjusted while the Pre-amplifier Output is muted. Please note that when mute is
cancelled, the Pre-amplifier Output level is determined by the current Volume Knob position. Use caution if
you listen to the headphones and speakers at significantly different volume levels.
