Front Panel Controls
The front panel of the audio chassis of the Reference Phono 10 features
two buttons, and an interactive touch screen.
Power On/Off: (left button) Supplies power from A.C. wall outlet to preamp;
indicated by active display window.
The Reference Phono 10 requires approximately 40 seconds to warm up;
this time is required to stabilize the power supply. See ‘Power-Up Procedure’
on the adjacent page for details. The same cycle also occurs in the event
of a power interruption.
Mute: (right button) When activated, electrically mutes all output of the
phono stage; 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 components and speakers from
unexpected signal pulses. When deactivated, ‘Mute’ disappears from the
display window allowing normal operation.
The Reference Phono 10 also has automatic muting to help protect 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 ash 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, component failure or speaker
malfunction.
