BV-120HR RED VOODOO All Tube Guitar Amplifier

The Rear Panel:19. IMPEDANCE SELECTOR: For the
best performance and least strain on your
amplifier, you MUST properly match the
impedance of your amplifier to that of your
speaker cabinet(s). Set the selector switch
to the 8 or 16 ohm position, depending on
the total impedance of your speaker cabi-
net(s). The chart below can help you deter-
mine that impedance based on the follow-
ing combinations of speakers connected in
parallel.
CAB. IMP.# OF CABS. TOTAL IMP.
8 OHMS 1 8 OHMS
16 OHMS 1 16 OHMS
16 OHMS 2 8 OHMS
32 OHMS 2 16 OHMS
32 OHMS 4 8 OHMS
20. MAIN SPEAKER JACK: Use this jack
to connect the amplifier to your primary
speaker cabinet. Always keep the imped-
ance at 8 or 16 ohms, with the impedance
selector switch (#19) at the proper setting.
NOTE: Use the MAIN SPEAKER jack
first. Then, if an extension speaker is
desired, connect it to the EXT.
SPEAKER jack.
21. EXT. SPEAKER JACK: Use this jack to
connect the amplifier to a secondary
speaker cabinet, after a speaker has been
connected to the main speaker jack (#20).
22. LINE OUT JACK: This 1/4” jack sup-
plies a line-level output signal from the
power amp for patching into a mixing
board, recording console or external ampli-
fier. The signal is tapped directly from the
speaker outputs, then attenuated and elec-
tronically compensated to simulate the
sound of a “miked” cabinet.
23. EFFECTS LOOP RETURN:
Connection from an external effects device
is made via this jack. Connect a shielded
instrument patch cord from the output jack
of the effect to the return jack. This jack is
active only when the effects loop is
switched in. The return jack also doubles
as a "power amp in" jack, to feed a line-
level signal directly into the BV-60H/120H's
internal power amp. This is useful when
"slaving" two amplifiers together.
24. EFFECTS LOOPSEND: Connection to
an external effects device is made via this
jack. Connect a shielded instrument patch
cord from the send jack to the input jack of
the effect. This jack is always active. The
send jack also doubles as a "preamp out"
jack, to feed a post-eq, pre-amplified signal
to a mixing board, recording console or
external amplifier.
25. FOOTSWITCH JACK: Connect a
stereo 1/4” (tip/ring/sleeve) here from a
two-button footswitch (such as the Crate
CFP-2) for remote control of channel
switching and the effects loop. The tip of
the jack is for the channel switching; the
ring is for the effects loop. When a
footswitch is connected here, the front
panel channel select and effects loop
switches are disabled.
26. AC LINE IN:Firmly plug the female end
of the supplied power cord into this socket,
pushing it in until it is fully seated. Plug the
male end of the cord into a properly
grounded AC outlet of the correct voltage.
DO NOT DEFEAT THE GROUND PIN OF
THE AC PLUG! Use only the supplied
power cord. If the amplifier is to be used
outside of the United States, see your
authorized Crate dealer for information
about alternate line cords and power con-
verters if needed.
27. FUSE: This fuse protects the amplifier
against damages caused by overload con-
ditions in the unit. If the fuse blows, replace
it only with the same size and type as indi-
cated on the rear panel. If the fuse blows
continually, the line voltage may be incor-
rect, or the amp may need servicing.
