Getting Started
The following steps will help you set up your amplifi er, and get the
levels just right.
SETTINGS:
1. Be sure the amplifi er’s POWER switch is off.
2. Turn down both Level controls.
3. On the rear panel, set the SUBSONIC FILTER switch
OFF and the CLIP LIMIT switch ON.
4. Determine which AMP MODE is best for your
application:
STEREO mode is the typical setup for amplifying
stereo signals. INPUT A is routed to CHANNEL
A output, and INPUT B is routed to CHANNEL B
output.
MONO mode is used for sending a mono signal
to both outputs, with separately adjustable level
controls. INPUT A is used in MONO mode (leave
INPUT B disconnected).
BRIDGE mode uses both outputs to double the
power to one speaker (or set of speakers). INPUT A is
used in BRIDGE mode (leave INPUT B disconnected
and the B Level control turned down).
NOTE: 4 ohms is the minimum speaker impedance
you should connect to the amplifi er in BRIDGE
mode. See “Do the Math” in Appendix B for
information on calculating speaker impedances.
5. Set the AMP MODE switch according to your
application.
CONNECTIONS:
1. Using balanced cables, make connections from
your mixer (or other signal source) MAIN OUT to
your amplifi er’s INPUTs.
2. In STEREO mode, connect the cables from your
signal source to the amplifi er’s INPUT jacks, either
XLR or 1/4” TRS.
• The XLR and TRS inputs for each channel are
wired in parallel.
• The balanced XLR inputs are wired as follows:
Pin 1 = shield (ground)
Pin 2 = hot (+)
Pin 3 = cold (–)
• The 1/4” TRS inputs are wired as follows:
Tip = hot (+)
Ring = cold (–)
Sleeve = shield (ground)
3. In MONO mode and BRIDGE mode, connect
one cable from the input source to INPUT A, and
connect nothing to INPUT B.
4. In STEREO and MONO modes, connect Speakon®
connectors to the CHANNEL A and CHANNEL B
speaker outputs.
• The Speakon connectors are wired as follows:
1+ = hot (+ speaker terminal)
1– = cold (– speaker terminal).
5. In BRIDGE mode, use the center Speakon
connector.
• The BRIDGED Speakon connector is wired as
follows:
1+ = hot (+ speaker terminal)
2+ = cold (– speaker terminal).
6. Plug all the sound system components into suitable
AC outlets, properly grounded and capable of
delivering adequate current.
7. Make sure your signal source is powered up and
delivering signal to the amp.
8. Turn the power amplifi er’s switch on. Verify that the
POWER LED lights.
9. Slowly turn up both Level controls on the amplifi er.
You should hear music and see the SIG LEDs
fl ashing. If the OL (Overload) LEDs are fl ashing, turn
down either the Level controls on the amp or the
source signal’s output level controls (i.e., master
faders), until the OL LEDs either blink occasionally
or not at all.
10. For quieter listening, it is preferable to adjust the
amp’s Level controls rather than the source signal’s
output level (unless you have the source’s control
all the way up!).
Things To Remember:
• Never plug amplifi er outputs
into anything except speakers
(unless you have an outboard box
specifi cally designed to handle
speaker-level signals).
• Before making connections to an amp or
reconfi guring an amp’s routing, turn the amp’s
level controls down, turn the power off, make the
changes, turn the power back on, and then turn
the level controls back up.
• If you shut down your equipment, turn off the
amplifi ers fi rst. When powering up, turn on the
amplifi ers last.
• Save the shipping box and packing material! You
may need it someday. If not, it makes a great end
table or hiding place for your cat.
