Laney CX12-A User Manual Download Page 4

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

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

When you first receive your Laney CX / CX-A cabinet, follow these simple procedures:

 (i) Ensure that the amplifier is the  correct voltage for the country it is to be used in.
(ii) Make all connections with a high quality shielded cable. You have probably spent considerable money on your PA system  
- don’t use cheap cable, it won’t do your gear justice .

This manual has been written for easy access of information.  The  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.

Later in the manual are some connection diagrams for a number of different set ups to show how to get the best from 
your PA system.

Best Wishes
