appropriately set to match the given load). If it has to drive speaker loads lower than 2
ohms, its output transformer or other components could be damaged. You can use 8- or
16-ohm extension cabinets, either alone or in pairs (one into each speaker output). A 2-
ohm speaker cabinet alone or a pair of 4-ohm extension speaker cabinets together can
be used, however, it is not an optimum match, and the Impedance Selector Switch must
be set at it's lowest setting, 4 ohms. 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 shortens the life of the amp's output tubes when the amp is operated at high levels..
Just because you cannot hear the amp does not mean it is not working hard. Always
use a heavy-gauge speaker cord. The larger the diameter of the wire, the lesser of
power to be lost. 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 further 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 Output
Your RIVERA Quiana or Fandango 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), and power-amp circuitry is sent from this jack. Use a shielded
cord connected between the amp's Line Out and the input of 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.
Impedance Selector
Set the Impedance Selector to match the impedance load of your internal speakers (8
Ohms), or a different setting when used with external cabinets Here's how:
4-ohm setting = One 4-ohm cabinet or two 8-ohm cabinets (one plugged into each
speaker output, like an internal 8 Ohm and an external 8 Ohm)). Use this setting if a 4 to
2 ohm load is needed to drive.
8-ohm setting = One 8-ohm cabinet or two 16-ohm cabinets (one plugged into each
speaker output, or when using just the internal speakers, 8 Ohms).
16-ohm setting = One 16-ohm cabinet plugged into the Speaker 1 jack
