3. Keyboard stereo:
Connect the right and left stereo outputs of your
keyboard to the corresponding inputs and the right
and left ROTOSPHERE outputs to the corresponding
inputs of your amp or mixing console.
To dial in clean rotor sounds, set the Drive control so
that the Tube Sat LED just starts to illuminate at the
loudest volume you intend to use. You can turn the
Drive control up further to set the level of tube
distortion. Set the ROTOSPHERE Output level control
and the gain controls at the mixing console so that
the mixing console´s input channel is not overloaded.
You do not want the mixing console itself to add
harsh, undesirable distortion to the signal.
4. Guitar mono to the preamp input:
(We recommend this option only when you do not
have any type of loop available in your amp where
you could patch in the signal post-preamp.) Use a
cable equipped with standard 1/4" plugs to connect
your guitar´s output jack to the ROTOSPHERE mono
input. Connect the ROTOSPHERE mono output to your
amp´s input. Please make sure you dial in a high
enough level via the Drive control, as guitar signal
levels are substantially lower than keyboard signal
levels. Set the Mode Switch at first to Guitar Mode.
This will adapt the frequency response for guitar
applications, somewhat similar to the RED BOX
Check out the sound of both modes and choose the
one you prefer. It is not absolutely essential to use
Guitar Mode exclusively.
5. Guitar mono to your amp´s loop through the
ROTOSPHERE:
Use a cable equipped with standard 1/4" plugs to
connect the FX Send jack from your amplifier to the
ROTOSPHERE mono input jack, and the ROTOSPHERE
mono output to the FX Return of your amp. The FX
loop is located between the preamp and power
amp, and has a higher signal level. Subsequently, the
effect will have a better signal-to-noise ratio and will
sound better.
6. Guitar mono to stereo in an amp´s FX loop.
If your amp has an effect loop with a mono send and
stereo returns, use a cable equipped with standard
1/4" plugs to connect the FX. Send jack of your
amplifier to the ROTOSPHERE mono input jack and
the ROTOSPHERE stereo output jacks to the amp´s
stereo FX Returns.
7. Guitar stereo in the loop of an amp/rack
system:
Use two standard 1/4" plug cables to connect the FX
Sends L + R to the corresponding inputs of the ROTO-
SPHERE and the ROTOSPHERE outputs to the amp´s
stereo FX RETURNS L + R.
8. External Footswitch:
The Remote jack lets you connect an external foots-
witch or MIDI switcher. You can switch the effect on
and off (Bypass) and switch back and forth between
Slow and Fast. Please refer to the section "Control
Features" to check the pin assignments of the stereo
1/4" jack. Also be aware of the fact that you can
only switch these functions remotely when the unit
itself is set to Bypass and Fast. With these settings, the
switches are "Off" and LEDs do not illumiate.
TROUBLESHOOTING

WARNING: DO NOT USE ANY POWER SUPPLY OTHER THAN
THE INCLUDED ORIGINAL ROTOSPHERE AC POWER PACK!
The ROTOSPHERE is a tube-driven device and draws a
great deal of current compared with most pedal
devices. A weaker power supply could easily com-
pared with most pedal devices. A weaker power
supply could easily overheat, burn itself out and
destroy the ROTOSPHERE along with it, possibly
causing a fire and leading to further damage and
injury.
Level problems: If you are using a guitar with this
effect, note that electric guitars have low output
signal levels and that you must turn the Drive control
up to a suitable level. We highly recommend that you
