Functions and Parameter Descriptions
To access the ROTARY SPEAKER function you must first select “ROTARY
SELECTED” in the CONFIG SELECT Parameter (see “SELECTING A CONFIGURA-
TION” section on page 66 for instructions on how to make this change). The CONFIG
SELECT function is the last function you can access with the FUNCTION SELECT
control.
After ROTARY SPEAKER has been selected and stored for that preset the
ROTARY SPEAKER function which will appear after the REVERB effect in the effect
chain.
The Rotary Speaker effect simulates the classic rotating speaker popular with
guitarists and keyboard players. It is designed to mimic the characteristics of the
classic mechanical rotating speaker with added versatility afforded by DSP.
The PARAMETER SELECT control will allow you to access each of the following
Rotary Speaker parameters
The PARAMETER ADJUST control allows you to adjust the selected parameter:
ROTARY
SPEAKER
Function
The ROTR SPK I/O parameter determines whether the simulated
speaker is rotating or not. Select IN to engage the Rotary circuit.
Select OUT to bypass the circuit.
The ROTATION SPEED parameter determines how fast the speaker is
rotating. With the PARAMETER ADJUST control you can select a
SLOW or FAST speed setting..
The ROTARY SPEAKER SLOW parameter sets the slow rotation
speed. (The horn and rotor will rotate at slightly different speeds.)
The ROTARY SPEAKER FAST parameter sets the fast rotation speed.
The ROTARY SPEAKER ACCELERATION parameter adjusts how
long it takes to reach the FAST SPEED or SLOW SPEED setting of
both the horn and the rotor. (The horn will accelerate faster than the
rotor.)
The BALANCE parameter adjusts the relative level of the rotor (lows)
vs. the horn (highs).

ROT SPK ACCEL
ROT BAL
*For added versatility
when using continuous
control, the SLOW
SPEED and FAST SPEED
parameters cover the
same range (0 to 100).
Therefore, it is possible to
have a SLOW setting
which is faster than the
FAST setting.
**Please note that when
using the Rotary Speaker
function has been
selected, the hi-pass filter
is no longer available.
