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.

Concept
THANK YOU
We at Laney are extremely pleased that you have decided to select a Concept product for
your sound requirements and we wish to reinforce your judgement by ensuring you get
off to a flying start by including this comprehensive user manual to assist you in getting
to know your equipment.
Before switching on please read this manual carefully since, whilst you may well be an
experienced user, no two brands are the same, and on reading this manual you will
become aware of the subtle advantageous differences that Concept offers over its
competitors.
UNPACKING
On unpacking your Concept mixer amp, please check carefully for any signs of damage
that may have occurred whilst in transit from the Laney factory to your dealer. In the unlikely
event that there has been damage, please re-pack your unit in its original carton and
consult your dealer.
1
We would strongly advise you to store away your original transit carton, since, in the
unlikely event that some time in the future your unit should develop a fault, you will be able
to return it to your dealer for rectification securely packed.
IMPORTANT SAFETY INFORMATION
Your Concept mixer amp should be fitted with a three pin 'grounded' (or 'earthed') plug.
Please make sure that the unit is powered from a 'grounded/earthed' outlet.
If changing or fitting a plug yourself, ensure that the applicable wiring code is adhered to;
for example, in the UK, the cable colour code for connections is as follows:
EARTH OR GROUND
NEUTRAL
LIVE
The Concept product should never be exposed to moisture or wetness under any
circumstances, since this would represent a possible shock or fire hazard, and may cause
expensive damage to your valuable possession.
GREEN/YELLOW
BLUE
BROWN
In the unlikely event that a fuse should blow, it is imperative that you or your engineer, use
a correctly rated replacement.
Details of the fuses required are printed on the back panel of the mixer amp. Please take
special care to use a 'time delay' fuse wherever stated.

TREBLE: Adjusts the high frequency response of the
1
individual channel.
MID: Adjusts the mid range frequency response of the
2
individual channel.
BASS: Adjusts the low frequency response of the
3
individual channel.
MON: Controls the amount of signal sent from the channel
4
to the ‘Monitor’ output socket, giving the user the
versatility of a separate monitor mix.
FX: Controls the amount of signal sent by the individual
5
channel to the onboard DSP section. The overall level of
effects is controlled via the FX return controls for the Main
and Monitor mix. See below.
LEVEL: Adjusts the channel level, enabling the user to
6
balance levels across channels.
PAD: Reduces the input gain of the channel, allowing the
7
user to match the input level of the channel with the output
level of the device to be amplified. This is especially useful
when amplifying instruments, mics., processors, etc. with
a very high output level.
LINE INPUT: Jack input socket, for all line level signals

(Keyboard, Signal Processor, Sampler, Drum Machine,
etc.).

MIC INPUT: XLR input for low impedance microphone
9
