OPERATION OF THE RP-9 PREAMPLIFIER
Powering up the System:
After all your connections have been made, you are now ready to turn the
preamplifier on. A primary power switch is located on the rear of the unit and is
shown in figure 1. You can leave this switch on all the time and it will keep the
solid state portions of the RP-9 energized even though the unit is powered down.
Very little power is used in standby and the RP-9 will sound its best shortly after
turn on. The power button located on the front panel is shown in figure 2 and is
used to power the RP-9 on and off between listening sessions. Your preamplifier
features soft-starting to prolong tube life as well as to suppress turn-on transients.
A countdown timer on the display shows the time remaining before the RP-9 is
ready to use. A ten second software lockout prevents turning the unit on and off in
quick succession. After turning on the preamplifier, turn on the power amplifier
and source material and you are ready for listening. The first time that your
preamp is turned on (and anytime it has been unplugged from the power outlet) it
is best to let the solid state components charge up for a few moments before
turning on the preamp. To do this, simply plug the RP-9 in and turn on the rear
power switch. Wait a minute or so and then power on at the front panel. This only
needs to be done when the RP-9 has been disconnected from the wall or the rear
switch has been turned off.
NOTE – The RP-9 will not play music for approximately 45 seconds
after power on while the preamp goes through its sequential start-up.
