IMPORTANT SAFETY INSTRUCTIONS

WARNING: When using electric products, basic cautions should always be followed, including the following:

1. Read all safety and operating instructions before using this product.

2. All safety and operating instructions should be retained for future reference.

3. Obey all cautions in the operating instructions and on the back of the unit.

4. All operating instructions should be followed.

5. This product should not be used near water, i.e., a bathtub, sink, swimming pool, w e t basement, etc.

6. This product should be located so that its position does not interfere with its proper ventilation. It should not be placed flat
against a wall or placed in a built-in enclosure that will impede the flow of cooling air.

7. This product should not be placed near a source of heat such as a stove, radiator, or another heat producing amplifier.

8. Connect only to a power supply of the type marked on the unit adjacent to the power supply cord.

9. Never break off the ground pin on the power supply cord.

10. Power supply cords should always be handled carefully. Never walk or place equipment on power supply cords.
Periodically check cords for cuts or signs of stress, especially at the plug and the point where the cord exits the unit.

11. The power supply cord should be unplugged when the unit is to be unused for long periods of time.

12. If this product is to be mounted in an equipment rack, rear support should be provided.
13 Metal parts can be cleaned with a damp rag. The vinyl covering used on some units can be cleaned with a damp rag or
ammonia based household cleaner if necessary. Disconnect unit from power supply before cleaning.

14. Care should be taken so that objects do not fall and liquids are not spilled into the unit through the ventilation holes or any
other openings.

15. This unit should be checked by a qualified service technician if:
a. The power supply cord or plug has been damaged.
b. Anything has fallen or been spilled into the unit.

c. The unit does not operate correctly.
d. The unit has been dropped or the enclosure damaged.

16. The user should not attempt to service this equipment. All service work should be done by a qualified service technician.

17. Exposure to extremely high noise levels may cause a permanent hearing loss. Individuals vary considerably in susceptibility
to noise induced hearing loss, but nearly everyone will lose some hearing if exposed to sufficiently intense noise for a sufficient
time. The U.S. Government’s Occupational Safety and Health Administration (OSHA) has specified the following permissible
noise level exposures.

Duration Per Day In Hours Sound Level dBA, Slow Response

8 90
6 92
4 95
3 97
2 100

I l/2 102

1 105
l/2 110
l/4 or less 115

According to OSHA, any exposure in excess of the above permissible limits could result in some hearing loss.
Earplugs or protectors in the ear canals or over the ears must be worn when operating this amplification system in order to
prevent a permanent hearing loss if exposure is in excess of the limits as set forth above. To ensure against potentially
dangerous exposure to high sound pressure levels, it is recommended that all persons exposed to equipment capable of
producing high sound pressure levels such as this amplification system be protected by hearing protectors while this unit is in
operation.

RETURN LEVEL: Adjusts the gain (sensitivity) of the RETURN jack.
SEND/RETURN: (

Effects loop) Connect SEND to the input of an effects device

and the output of the effects device to the RETURN.

INPUT 2: Plug in connection for high-output/pre amplified instruments. Provides

6dB less gain (sensitivity) than INPUT 1.

Multiple CD Amps – Connect PRE-OUT on the primary unit to the PA-IN of the
auxiliary unit. The primary unit is used to control all auxiliary units except the
PRESENCE which remains active on each unit.

This symbol warns the user of dangerous voltage levels localized within the
enclosure.

VOICING: Provides a low-frequency boost for the Drive channel
BRIGHT: Provides a high-frequency boost for both the Clean and Drive

channels.

This symbol advises the user to read all accompanying literature for safe
operation of the unit.

MID BOOST: Provides a mid-frequency boost for both the Clean and Drive

channels.

•Read, retain, and follow all instructions. Heed all warnings.

•Only connect the power supply cord to an earth grounded AC receptacle in accordance with
