Description of Controls
Front Panel Rotary Controls
The Reference 5 has two microprocessor-driven
rotary controls.
The rotary control on the left adjusts Volume (output
level) up or down for both L and R channels.
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
both a bar graph with marker and 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.
The rotary control (on the right) selects any of six
input sources connected to the preamp: CD,
Tuner, Phono, Video,Aux 1 and Aux 2. Each of
these sources may also be selected via direct
access buttons on the remote control. The
selected source is indicated in the display window.
Front Panel and Remote Control
Buttons
POWER ON/OFF: 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. This also
occurs in the event of power interruption. Upon
completing the cycle, ‘Mute’ will cease flashing.
The preamp will remain muted until normal
operation is selected by pressing the ‘Mute’ button.
MUTE: 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. When deactivated, ‘Mute’ disappears from
the display window allowing normal operation.
Function also on remote control.
The Reference 5 also has automatic muting to help
protects system components during A.C. power
interruptions or low line voltage. When sensing
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.
PROCESSOR (PROC): May be selected by button on
front panel or on remote control. Selects external
A-V (home theater) processor as input source and
controller of volume level for R and L channels.
Reference 5 SE provides Unity Gain when this input
is selected.
When engaged, ‘PROC’ will appear in the display,
and the numerical volume setting will read ‘NA’ (for
‘Not Applicable’) because gain is fixed and not
adjustable. The preamp will also mute the input
after ‘PROC’ is engaged.
WARNING:
Before unmuting the ‘PROC’ input, be
sure to turn the volume down on the
home theater processor. Never
connect a source with a fixed level
output (DVD player, tuner, CD, etc.) to the ‘PROC’
input or the amplifier(s) and speaker system could
be damaged when the Reference 5 SE is unmuted.
VOLUME UP/DOWN : Using rotary control on front
pane lor VOL UP/VOL DN buttons on remote,
increases/decreases overall volume level of both
channels equally for whichever input has been
selected. Caution: do not turn up volume beyond
normal listening levels when “Mute” is engaged to
avoid unexpected or possibly damaging sound
levels. It is a good idea to reduce volume
whenever changing program sources, even when
muted.
BAL/SE: Select as appropriate for each input. For
source components having balanced (XLR)
connections to the Reference 5, select BAL. For
single-ended (RCA) sources, select SE. Once
selected for an input source, the setting is
memorized.
INVERT: Inverts absolute phase of the output signal.
MONO: Sums L and R input for mono output from
any source selected.
Remote Control only Functions
DISPLAY DOWN/DISPLAY UP (DSP DN/DSP UP):
Decreases/increases display intensity, offering 6
levels of bright-ness and display ‘off’. If display “off”
is selected, a small egment of pixels remains
illuminated in the center of the display window as a
reminder the unit is turned on. In display ‘off’ mode
the display will illuminate for 10 seconds when any
button (except Power on/off) is selected, allowing
for control function navigation.
BALANCE (BAL L/BAL R): Adjusts balance left or right
adjustment appears in display window as movable
marker on bar graph. Useful for compensating for
