Front Panel Controls
The Reference Phono 3 has six buttons:
Power, Menu, Option, Enter, Input, and
Mute.
Power On/Off
Supplies power from the A.C. wall outlet
to preamp; indicated by active display
window. The Reference Phono 3 requires
approximately 2 minutes to warm up; this
time is required to stabilize the circuitry.
See ‘Start-Up Procedure’ on page 11 for
details.
Menu
The menu button enters the setup menu
of the Reference Phono 3 to allow
customizing certain settings of the
preamplifier. See page 15 for further details
about using the setup menu.
Option
The Option button is used in conjunction
with the Menu button to select the various
options in the settings menu.
Enter
The Enter button is used in conjunction with
the Menu button to make changes to the
systems settings of the Reference Phono 3.
Mute
When activated, Mute electrically disables
all outputs of the phono preamplifier;
indicated by ‘MUTE’ in display window,
in the bottom right corner. 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.
Remote Only Functions
In addition to the controls found on the
front panel, the remote control offers
access to the following additional
features of the Reference Phono3:
Hours
Pressing the ‘HOURS’ button will display
the total accumulated hours of operation
for the Reference Phono 3. This is useful
to determine the approximate number
of hours the vacuum tubes have been in
use. After five seconds, the display will
revert to the normal operation screen.
After replacing vacuum tubes, the hours
counter should be reset (see instructions
under ‘Settings Menu’ on page 16).
Note
The installed 6H30 vacuum tubes have
an average life span of approximately
4,000 hours, and the 6550WE has an
average life span of approximately 2,000
hours. After this time, we recommend
replacing them to maintain the best
performance of your preamplifier.
Gain
The ‘LO GAIN’ and ‘HI GAIN’ buttons switch
between the two gain settings of the
Reference Phono 3. When switching from
LOW to HIGH gain position, the phono
preamplifier mutes as a precaution and
reminder to lower the volume level of
your preamplifier, to prevent possible
system overload or damage. The 23dB
gain difference between the LOW and
HIGH gain positions is substantial.
