patch the ROTOSPHERE into a loop, as these feed a

substantially higher signal level to the effect.

Noise: The TUBE ROTOSPHERE is an analog Leslie

emulator. We designed it to deliver a sound as true as

possible to the original Leslie

tube is primarily responsible for the highly desirable

tube tone. But we aware that the way these

components are configured and the nature of the

rotary effect add an audible noise level to the signal.

If you set the Drive control (in other words, they input

sensitivity) to a suitable level for the input signal, you

will find that peripheral noise remains at a minimum

level.

Tube: When you switch the ROTOSPHERE on (when

you plug in the power pack), the Tube Sat LED will

illuminate until the tube has heated up to operating

temperature. If the tube is already warm, this delay

will naturally be shorter. If the LED does not illuminate,

double-check the power pack to make sure it is

plugged in all the way. If the LED continues to

illuminate for longer than the standard warm-up

period, then the tube is defective and needs to be

replaced. If you find that the effect generates dis-

harmonic distortion or sounds muddy, in all likelihood

the tube is worn out and needs to be replaced.

The tube should be replaced by qualified service

technicians only.

Tip: In mono mode, the left channel will deliver a

more intense effect signal than the right (right

channel input, left channel output; do not access the

right channel output).

Symptoms and solutions:

• Distortion is too brittle and edgy (with a keyboard):

Check the Mode switch to see if it is set to Guitar

Mode, and adjust your mixing console input gain.

• The output level of the ROTOSPHERE seems un-

usually low (in mono mode): Check if you are

accessing the correct mono input.

• The effect signal is too loud in comparison to the

original signal (in mono mode): Check if you are

accessing the correct output (R, Mono).

• Distortion in Bypass mode: The input signal level is

too high. It may not exceed + 12 dB. Reduce the

output level of your keyboard, or reduce the Drive

control, or both.

• The LEDs do not illuminate: Double-check that the

power supply is correctly plugged in, or check the

circuit breakers in your AC current.

• The LEDs illuminate, but you are not getting a signal:

Check the cables and/or the connected

instrument.

• The external footswitch does not work: Pull the

stereo 1/4" plug out and set the Bypass and Slow-

Fast to Off (the LEDs located above the switches do

not illuminate). Now reinsert the plug. The foot-

switch should operate as intended.
