cabinet (if the internal speakers are not connected), or a 4-ohm extension speaker
cabinet with the internal speakers can be used sparingly. The only time you may run the
amp without a speaker connected is if you have a proper "dummy" impedance load box
plugged into the speaker output. Using a dummy load protects the output transformer,
but prolonged use at high power levels shortens the life of the amp's output tubes. If you
use your Hundred Duo Twelve to drive an extension cabinet, use a heavy-gauge
speaker cord. A shielded guitar cord can't handle the power that your amp provides, and
therefore won't sound right--plus it may actually harm your amp. Refer to the connection
diagrams for more information.
Note:
Never use a speaker output to connect directly to the input of a
mixer, a tape recorder, a slave amp, or headphones. For further
information, refer to the hook-up diagrams for proper connection with
extension speaker cabinets.
Line Out
Your Rivera amp can drive another Rivera amp, power amp, or other guitar amplifier.
The Line Out is post-power amp, so every bit of tone from your preamp, effects (if
used), reverb, and power-amp circuitry is sent from this jack. Use a shielded cord
connected between the R Series amp's Line Out and the input to a second amplifier
(check that amp's manual--it may recommend a specific input). The Line Out can also
be used to feed a signal to a tape recorder or mixer. Although the recorder or mixer
doesn't receive the tone that comes from the speaker, it does receive all of the signal
from every other stage of the amp, and for live-performance recording it does an
excellent job of isolating your guitar sound.
Note:
Do not connect the Line Out to speakers or headphones. For
further information, refer to the hook-up diagrams for proper connection.
Footswitch jack
This 8-pin DIN plug is designed to work specifically with the included FS-7 footswitch.
Your Hundred Duo Twelve will function perfectly without a footswitch. However, the
footswitch provides a hands-free way to switch channels and select boost functions. Its
three switches control the following:
Channel Select
Gain Boost for Channel 1
Ninja Boost for Channel 2
Note:
If you are using the FS-7 footswitch, make sure that all pull switches on the amp's
front panel are pushed in. If any of the pull switches is pulled out, then the
corresponding footswitch function will not operate. Also, the switches and their LEDs
are driven by the amplifier's power; there is no battery to replace inside the FS-7.
