Owner’s Manual
Introduction
The Ultimate Comp is a 100% analog compressor pedal, representing a warm, studio-like optical compression sound that you can hardly find on other types of compressor pedals.
Precautions
READ CAREFULLY BEFORE PROCEEDING Please keep this manual in a convenient place
for future reference.
Power Supply
Always use a DC 9V center negative AC adapter. Use of an adapter other than
that specified could damage the unit or cause malfunction and pose a safety
hazard. Always connect the AC adapter to an AC outlet that supplies the rated
voltage required by the adapter. Disconnect the AC adapter from the AC outlet
when during lightning storms or not use the unit for an extended period.
Connections
Always turn off the power before connecting or disconnecting. Make sure to
disconnect all cables and AC adapter before moving the unit. This will help
prevent malfunction and damage.
Environment Considerations
Avoid using the unit in any of the following conditions that could cause
malfunction:
- Extremely hot or cold places
- Under direct sunlight
- Magnetic fields
- Near heaters and other heat sources
- Sandy or dusty places
- Places that are extremely humid or exposed to splashing water
- Places with lots of vibrations
Electrical Interference
Devices that are very susceptible to interference or that emit powerful
electromagnetic waves (e.g. radios and TVs) should not be placed near this
unit, as interference could occur. Electromagnetic interference could cause
malfunction and could corrupt or destroy data. Always operate this unit at a
suitable distance from these devices.
Handling
Do not apply excessive force to the switches and other controls, exposing the
unit to strong impacts, which could cause it to break. Do not put foreign
objects or liquids into the unit. Never open the case or attempt to modify the
product in any way since this can result in damage to the unit. Clean only
with a soft, dry cloth.
