Technical Specifications - Hughes & Kettner TUBE ROTOSPHERE MK II Manual De Instrucciones

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).
NOTE: THE ROTATION SPEED AND INITIAL ACCELERATION
OF THE ROTSPHERE ARE FIXED PRESETS BASED ON THE
ORIGINAL ROTARY CABINET SPECIFICATIONS. THESE
CANNOT BE MANIPULATED, NOT EVEN BY AN
EXPERIENCED TECHNICIAN.

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.
