GL2200 SERVICE MANUAL
Introduction
The information presented in this manual is intended for competent technical personnel to carry out
service and product support for the GL2200 range of consoles. We assume that the reader is familiar
with the related electronic theory and audio terminology, and is able to carry out servicing, faultfinding
and repair of audio equipment of this type. Service personnel should also be familiar with audio
systems, mains earthing and power requirements, as well as handling precautions.
For information on the configuration, operation and application of the GL2200 range, please
refer to GL2200 User Guide (A&H Part no: AP3388).
Whilst we believe the information in this manual to be reliable we do not assume responsibility for
inaccuracies. We also reserve the right to make changes in the interest of further product
development.
Service and Technical Support
Under normal conditions the GL2200 does not require user maintenance or internal calibration. Any
service work required should be carried out by qualified service personnel only.
We are able to offer further product support through our world-wide network of approved dealers and
service agents. You can also access our Web site on the Internet for information on our product
range, assistance with your technical queries or simply to chat about audio matters. To help us
provide the most efficient service please keep a record of the console serial number, the date and
place of purchase to be quoted in any communication regarding this product.
SAFETY WARNING!
Mains electricity is dangerous and can kill. Mains voltage
is present within the console power supply unit.
Do not remove the power supply cover with mains
electricity connected. To ensure your safety, mains earth
is connected to the chassis through the power lead. Do
not remove this mains earth connection.
To avoid the risk of fire, replace the mains fuse only with
the correct value and type as indicated on the power
supply unit.
The internal power supply unit contains no serviceable components
and must be replaced as a complete unit if a failure occurs.
General Precautions
Your GL2200 is ruggedly constructed to give many years of reliable operation. However, you will
extend the life of the console and preserve its cosmetics by applying these simple common sense
precautions.
x
Avoid storing or using the mixing console in conditions of excessive heat or cold, or in positions
where it is likely to be subject to vibration, dust, dirt or moisture.
x
Do not use any liquids to clean the control surface of the console, a soft dry brush or dry lint-free
cloth is ideal.
x
Use only water or ethyl alcohol to clean the trim and scribble strips. Other solvents may cause
damage to paint or plastic parts.
x
The faders, switches and potentiometers are lubricated for life. The use of electrical lubricants on
these parts is not recommended.
x
Avoid using the console close to strong sources of electromagnetic radiation (e.g. video monitors,
high power electric cabling): this may cause degradation of the audio quality due to induced
voltages in connecting leads and chassis. For the same reason, always site any external power
supply away from the unit.

Flightcasing The Console
If the console is to be regularly moved we recommend that it is installed in a foam-lined flightcase.
At all times avoid applying excessive force to any knobs, switches or connectors.
