-Stop adjust trimmer-
• Stop (recessed trimmer on the control panel) this control adjusts the position of the rotor when
the stop button is pushed. It is initially set to face the drum forward after the drum coasts to a
complete stop. (The control pedal stop button LED is on).
• Age Over time, as the belt and ball bearings ware, this may need adjustment. CAUTION!
This is a small trim pot that requires a tiny screwdriver to adjust. The trim pot can be broken
with an improper tool or rough adjustment technique.
• Adjustment Observe the rotary drum either by removing the front grill or using a flashlight
shinning through the grill cloth. Make small, careful adjustments to the “stop” trimmer.
1. Run the rotor fast for a few minutes and then push stop. The rotor spins counter clockwise (left
to right). Push the pedal stop button and observe the rotor position when completely stopped.
If the rotor stops within +15 to –15 degrees of front center, that is normal.
2. If the rotor stops to the right of center, turn the “stop” control counter clockwise a small
amount, run on slow for 30 seconds and test again. Repeat if needed.
3. If the rotor stops to the left of center, turn the “stop” control clockwise a small amount, run on
slow for 30 seconds and test again. Repeat if needed.
-Footswitch control-
• Cord length The SRV-112 is shipped with a two button push on/push off LED speed control
pedal. The removable cord is a 15 foot TRS type. Longer cords or extensions can be used up to
about 50 feet. A heavier gage wire can be used for even longer runs.
• Speed Button When the LED is off, slow speed is selected. (See control panel). When the
speed button is pushed again, the LED illuminates and fast speed is added to the slow.
• Stop Button When stop is pushed, LED illuminated, slow and fast are disabled and the rotor
will ramp down to a complete stop with the rotor facing forward. When stop is pushed again,
the LED goes off and the rotor will ramp to the current speed selected.
-Rear Panel Connections-
• 8 Ohm input Connect your amplifier’s output here with a good speaker cord. The connector
and speakers are isolated from ground.
• Microphones The SRV-112 has two built in dynamic microphones for convenient connection
to a PA system or recording console. The XLR’s are labeled left and right, the outputs are low
impedance balanced.
• AC power inlet module Connect to specified and grounded power only. The fuse is located in
the power inlet module just above the inlet. Use specified value only.
-Speakers-
• Stock speaker The SRV-112 is shipped with one Eminence™ Screamin’ Eagle 8 ohm
speaker. It can handle of 50 watts RMS of power.
• Considerations The Screamin’ Eagle is a good match for the SRV-112’s cabinet which has
different speaker requirements since the speaker is sounding through a rotary chute.
• Remove/replace The speaker is mounted with machine screws into steel inserts so you can
change them easily. Remove the top and bottom rear panels to gain access. Caution! If you
change speakers be sure resulting Ohms load matches your amplifier. If you are not sure,
contact the amplifier’s manufacturer.
