Dear Player,
Thank you very much for purchasing your new Laney product and becoming part of the worldwide Laney family. Each and every Laney unit
is designed and built with the utmost attention to care and detail, so I trust yours will give you many years of enjoyment.
Laney products have a heritage which stretches back to 1967 when I first began building valve amplifiers in my parent’s garage. Since then
we have moved on from strength to strength developing an extensive range of guitar, bass, public address and keyboard amplification
products along with a list of Laney endorsees that includes some of the world’s most famous and respected musicians. At the same time
we believe we have not lost sight of the reason Laney was founded in the first place - a dedication to building great sounding amplification
for working musicians.
Warm Regards,
Lyndon Laney CEO

INTRODUCTION
The GS412IA & GS412IS are a pair 4 x 12” cabinets optimised for use with GH50L, GH100L, VH100R - or indeed any amplifier in the
Laney range.
Rated at 320 watts (16 ohms) these cabinets can be used in isolation or together to form an 8 x 12 stack. Construction features a robust
plywood cabinet, with large side bar handles, castor cups on top of the straight cabinet to allow stacking, stainless steel corner protection
and a set of roadworthy casters mounted to each model for ease of mobility.
Every Laney product is extensively play tested by experienced guitarists to ensure it has the tone and durability to perform at the very
highest level, before being shipped to our customers.
We hope you enjoy using your new extension cabinet as much as we enjoyed designing and making it. It should give you years of trouble-
free service, however please take time to read this manual, as it will allow you to get the best from your GS412IA or GS412IS.

1). Read & Retain these Instructions carefully before installing or operating this product.
2). Comply with Warnings: All warnings and instructions for these products should be adhered to.
3). Unpacking: On unpacking your product please check carefully for any signs of damage that may have occured whilst in transit from the
Laney factory to your dealer. In the unlikely event that there has been damage, please repack your unit in it original carton and consult your
dealer. We strongly advise you to keep your original transit carton, since in the unlikly event that your unit should develop a fault, you will be
able to return it to you dealer for rectification securely packed.
4). Amplifier Connection: In order to avoid damage , it is advisable to establish and follow a pattern for turning on and off your system.
With all system parts connected, turn on source equipment, tape decks, cd players, mixers, effects processors etc, BEFORE turing on your
guitar amplifier. Many products have large transient surges at turn on and off which can cause damage to your speakers.
By turning on your guitar amplifier LAST and making sure its level control is set to a minimum, any transients from other equipment should not
reach your loud speakers. Wait till all system parts have stabillised, usually a couple of seconds. Similarly when turning off your system always
turn down the level controls on your guitar amplifier and then turn off its power before turning off other equipment
5). Cables: Never use shielded or microphone cable for any speaker connections as this will not be stubstantial enough to handle the amplifier
load and could cause damage to your complete system.
6). Caution: These professional loudspeaker systems are capable of generating very high
sound pressure levels. Use care with placement and operation to avoid excessive levels that
can cause permament hearing damage.
7). 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 permissible noise level exposure in the chart oposite.
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 oposite. 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.
8). Servicing: The user should not attempt to service these products. Refer all servicing to qualified service personnel
