Description of Controls

Front Panel Controls

The Reference 10 has one microprocessor-driven
rotary control and two buttons (Power and Mute).
Rotary control: Adjusts Volume (output level) up or
down for both L and R channels, and adjusts the
balance when the balance function is selected on
the main screen. Volume control is also selectable
via Vol UP and Vol DN buttons on the remote control.
Volume adjustment is indicated in the display window
by numeric digits on 0–103 scale.
Do not turn volume up beyond normal listening
levels when 'mute' is engaged to avoid unexpected
or possibly damaging sound levels. Reduce volume
level whenever changing input sources, even when
muted.
POWER ON/OFF: (left button beneath rotary control)
Supplies power from A.C. wall outlet to preamp;
indicated by active display window. Function also
on remote control.
For approximately 40 seconds after start up, 'Mute'
appears in the display window and flashes until the
automatic muting cycle is completed.
occurs in the event of power interruption.
completing the cycle, 'Mute' will cease flashing. The
preamp will remain muted until normal operation is
selected by pressing the 'Mute' button.
MUTE: (right button beneath rotary control) When
activated, electrically mutes all output of the
preamplifier; indicated by 'Mute' in display window.
This control should be activated before switching
inputs, changing connections or shutting down your
audio system to help protect your amplifier and
speakers from unexpected signal pulses.
deactivated, 'Mute' disappears from the display
window allowing normal operation. Function also
on remote control.
The Reference 10 also has automatic muting to help
protects system components during A.C. power
interruptions or low line voltage.
these conditions, the preamp automatically goes
into 'Mute' and disables all outputs. The 40-second
warm-up timer will restart and 'Mute' will flash in the
display window when normal power conditions have
been restored.
Note that automatic muting is only designed to
protect against power line interruptions or severe
voltage drop. It will not mute in the event of subsonic
transmissions from a faulty input source, amplifier
failure or speaker malfunction.

When engaged, 'Pass Thru' will appear in the display,
and the gain is fixed and not adjustable. The preamp
will also mute the input after 'Pass Thru' is engaged.
