Operation
Start-Up
• Secure interconnects between the amplifier
and your preamplifier; attach speaker leads
to the appropriate output terminals.
• Attach supplied power cord to rear IEC
inlet of amplifier, and plug other end into
grounded A.C. power receptacle.
• Turn on preamp and all other components;
mute preamp output.
• Press Reference 750 SE front panel control
switch. Green power LED will light.
• The Reference 750 SE has an automatic
mute circuit which lasts approximately 45
seconds to allows the amplifier to stabilize
voltage before becoming active.
• Unmute preamplifier output, initiate
source component signal, and adjust gain
as appropriate.
Shut-Down
• Mute preamplifier output.
• Turn off Reference 750 SE front panel
power switch.
• Turn off preamplifier and then the
associated input source components.
Important!
After the Reference 750 SE is turned off, wait
at least five minutes before turning it on again.
This allows the large bank of storage capacitors
to drain energy. Not allowing enough time for
this process can result in blown fuses or other
damage to your amplifier.
Display Brightness Adjustment
The front panel meter display is illuminated
with ultra low-noise, low voltage LED lighting
which has no impact on sound quality when
turned on. The display brightness has three
settings: high, low, and off. To change the
brightness of the display, locate the front
panel button labeled ‘Light’. Press this button
to toggle through the three available settings.
Fan
Press the fan switch to select low (dim Power
LED) or high (bright Power LED) for fan speed
setting. (Note - this is only applicable when
the optional top cover with ventilation fans
is installed).
Meter
Press meter button to turn on or off the
power level monitoring meter function.
Note
The light, fan, and meter settings at turn off
are retained each time the amplifier is turned
on.
Break-in
All quality stereo equipment benefits from a
break-in period; during this time, the various
components, wiring and solder connections
change as electrical signals pass through
them. While your Reference 750 SE will sound
fantastic out of the box, it will only improve
with continued use.
