Note: Loads that are not matched properly may harm your amp. If
unequal speaker cabinets loads, i.e. a 4 ohm cabinet and an 8 ohm
cabinet are used together, unequal amounts of power may be
distributed to these cabinets due to a non symmetrical load.
If you aren't sure if your speaker load is correct, contact your RIVERA dealer, or call
RIVERA Customer Service.
Footswitch jack
This 8-pin DIN plug is designed to work specifically with the included FS-7 footswitch.
Your Quiana/Fandango amp 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 1-2
Gain Boost for Channel 1
Gain Boost for Channel 2
Note: If you are using the FS-7 footswitch, all of the Front Panel switching functions
remain intact and can be selected by the respective controls pull-switch function. Also,
the switches and their LEDs are driven by the amplifier's power; there is no battery to
replace inside the FS-7.
The footswitch jack can also be used to connect the optional FS7M MIDI interface. This
allows the amp to be controlled by any MIDI controller including the Rivera Head
Master. The MIDI interface replaces the footswitch, the interface and the pedal cannot
be used at the same time.
Effects Loop
Of course, you can use pedals and rack-mounted effects between your guitar and the
amp. In fact, that's where most wah-wahs and other pedals sound exceptionally good.
However, rack signal processors are often best suited to being placed after the
Preamp's tone-shaping circuitry. Your Quiana/Fandango's Effects Loop is designed to
give you the best match between the amp and the processor by allowing you to set the
level of the signal going to the effect, as well as the one coming back. Therefore, you
can tailor your amp/effects levels for best signal-to-noise ratio and the amount of
distortion you want. Note: The Effects Loop send can be used to route a signal to a
guitar tuner, recording mixer, another guitar amplifiers effects loop return (for Bi-Mono
amping), etc.
The Effects Loop comes after the Preamp section. In addition, its low-impedance
circuitry lets you drive everything from the simplest stomp-box effect to the most
sophisticated pro signal processor with excellent results. It's also fully buffered, meaning
that it can drive long cords and line-level gear and mixing consoles. (Because the signal
is electrically unbalanced, you can use an unbalanced-to-balanced output transformer
to connect to equipment requiring a balanced input.)
