On units with remote control, this knob is spring loaded; moving the control clockwise will
toggle between the “Mute” and “Operate” condition. When muted, a red glow will be
observed in the LED. On occasion the preamplifier may seem not to have responded to a
turn of the “Mute” knob; this is due to “contact bounce” in the switch. Simply turn the knob
again until the desired condition is attained.
The preamplifier must be muted before power is switched on or off. When switching on,
always allow the preamplifier to warm up for a minute before you unmute the unit; failure
to wait can cause a transient to be sent through your power amplifier that might cause
damage to your loudspeakers.
STANDARD PREAMPLIFIERS WITH REMOTE CONTROL
The optional remote control allows for wireless adjustment of “Mute” and “Volume”.
The remote wand is powered by two “AAA” batteries. These should be of the alkaline type.
You will need to install them in the wand before using the remote. Since batteries can leak,
they should be removed from the wand if it is not going to be used for an extended period
of time.
Volume Up/Down: These buttons cause a motor to turn the volume control. Motorized
controls offer superior sound, as well as direct visual indication of volume setting. The front
panel control may also be used directly in the conventional way.
Mute: Pressing either side of the “Mute” button will toggle between the “Mute” and
“Operate” condition. When muted, a red glow will be observed in the LED indicator. Mute
is automatically engaged when switching on units equipped with the remote control option.
Always mute the preamplifier before switching power off or on. When turning on, allow the
unit to warm up for one minute before unmuting.
OBTAINING THE BEST PERFORMANCE
Precautions: Before removing cover, mute the preamplifier, turn power switch to “off”
position, disconnect the AC power cord from the wall, remove all interconnects, and wait
15 minutes. FOLLOWING THESE STEPS IS IMPORTANT TO PROTECT YOUR
SAFETY. To prevent loss, place cover screws in a small receptacle. To avoid the risk of
shock or other injury, reinstall cover before reconnecting the system or turning the unit on.
