USER MANUAL

Intended to alert the user to the presence of uninstalled "dangerous voltage" within the product's enclosure
that may be of sufficient magnitude to constitute a risk of electric shock to persons.

Intended to alert the user of the presence of important operating and maintenance (servicing) instructions in
the literature accompanying the product.

Caution: Risk of electrical shock - DO NOT OPEN!
Caution: To reduce the risk of electrical shock, do not remove cover. No user servicable parts inside. Refer servicing to

qualified service personnel.

WARNING: To prevernt electrical shock or fire hazard, do not expose this appliance to rain or moisture. Before using this
appliance, read the operating guide for further warnings.

This apparatus must be earthed.

EMC warning

It is inherent in the design of a loudspeaker and in the design of guitar pickups that they should emit or be affected by electro magnetic fields. Loudspeaker enclosures should not
be used less than two meters away from equipment, which is likely to be affected by electro magnetic interference.
Likewise, guitar fitted with electro magnetic pickups should not be used less than two meters away from any source of emissions such as loudspeakers. Emissions from
loudspeakers are dependent on the frequency characteristics of the drive unit. Levels were measured direct from the driver of 30 dBuV. These levels are reduced to a safe level at
a distance of 1,27 meters from the drivers.

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, wet 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 up enclosure that will impede the flow of cooling air.

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

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

9. Never break off the ground pin on a 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 chord 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 cloth. The vinyl covering used on some units can be cleaned with a damp
cloth or ammonia based household cleaner if necessary. Disconnect the unit from the power supply before cleaning.

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

15. A qualified service technician should check the unit if:

The power cord has been damaged
Anything has fallen or spilled into the unit
The unit does not appear to operate correctly
The unit has been dropped or the enclosure damaged.

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

17. Exposure to extremely high noise levels may cause a permanent hearing gloss. Individuals very 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 exposure.

Duration Per Day In Hours Sound Level dBA, slow response

8 90
6 92
4 95
3 97
2 100
1 ½ 102
1 105
½ 110
¼ or less 115

According to OSHA, any exposure in excess of the above permissible limits could result in some hearing loss. Ear plugs 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 exceeds the limits 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.

INTRODUCTION

Congratulations on your decision to purchase a Laney amplifier.

Laney products are designed with ease of operation as a primary objective, however to ensure you
derive the best from your new amplifier, it is important you take time to read this user manual and to
familiarise yourself with the control functions and facilities available

BEFORE
SWITCHING ON

After unpacking your amplifier check that it is factory fitted with a three pin 'grounded' (or earthed) plug.
Before plugging into the power supply ensure you are connecting to a grounded earth outlet.

If you should wish to change the factory fitted plug yourself, ensure that the wiring convention applicable to
the country where the amplifier is to be used is strictly conformed to. As an example in the United Kingdom
the cable colour code for connections are as follows.

EARTH OR GROUND - GREEN/YELLOW
NEUTRAL - BLUE
LIVE - BROWN

1

This manual has been written for easy access of information. The front and rear panels of each unit
are graphically illustrated, with each control and feature numbered. For a description of the function of
each control feature, simply check the number with the explanations adjacent to each panel.

Your Laney amplifier has undergone a thorough two stage, pre-delivery inspection, involving actual
play testing, as well as burn in.

When you first receive your Laney amp, follow these simple procedures:

(I) Ensure that the amplifier is set at the correct voltage for the country it is to be used in.

(ii) Connect your instrument with a high quality instrument cable. Use of cheap cables will compromise
the sound of your instrument and your amplifier.
