AC POWER CONNECTION
Once all audio and system connections have been made, connect the supplied power cord(s) to the
RA2400/RA7300 first and then connect it to an AC power source. Note that the RA7300 uses two
power cords whereas the RA2400 uses one.
IMPORTANT: Make certain that the amplifier is turned off and that any auto on/off
trigger device (if used) is off BEFORE connecting the amplifier’s power cord and plugging
it into an AC outlet. Also make sure all other equipment is powered off.
CAUTION: Do not plug the amplifier directly into the “Switched Accessory” outlet of another device!
These outlets are intended for use with low current draw products having a low current draw, such as
tuners, CD players or cassette decks. These cannot handle the high current draw of a power amplifier.
Using these outlets for a power amplifier is a significant safety hazard and if used in this way will void
warranty.
NOTE: It is not recommended that you connect other power amplifiers or products with a high current
draw, to the same AC power circuit as the amplifier. If this is unavoidable the Ultra-Soft-Start circuitry of
your amp will prevent excessively high in-rush current.
RA2400/RA7300 OPERATION
After all connections have been made you are ready for operation
First, one at a time, turn on the other components and processor in your sound system.
It is always a good idea to turn on the amplifier
LAST
. This avoids the possibility of any power on
“pops” or transients from other equipment being amplified and sent to your speakers where they
may cause damage.
To avoid damage to speakers, always start with a low volume level on your controller or preamp.
Manual Power On
Press the RA2400/RA7300’s front panel power plate (switch is underneath the plate). After a short
pause the blue LEDs should illuminate, indicating power is on, and sound should be supplied to the
speakers. The pause is intentional and protects your speakers from damage as the
RA2400/RA7300 stabilizes. Note that the RA2400/RA7300 rear panel power switch(es) must be in
the on position for the front panel power switch to work.
Manual Power Off
To turn the RA2400/RA7300 off, press the front panel power plate. The blue LEDs should
extinguish and the amplifier should turn off.
