Laney GH100L Operating Instructions Manual Download Page 3

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.

NOTE

                                     

This manual has been written for easy access of information.  The 
front and rear panels 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.
When you first receive your Laney guitar amplifier, follow these 
simple procedures:

(i)

 Ensure that the amplifier is the correct voltage for the country 

it is to be used in.

(ii)

 Connect your instrument with a high quality shielded 

instrument cable.  You have probably spent considerable money on 
your amplifier and guitar - don’t use poor quality cable it won’t do 
your gear justice.
Please retain your original carton and packaging so in the unlikely 
event that some time in the future your amplifier should require 
servicing you will be able to return it to your dealer securely 
packed.
Care of your Laney amplifier will prolong it's life.....and yours!
