Congratulations on the purchase of
your Hughes & Kettner ATS
The
ATS 120 has been developed to combine optimum sound quality and flexibility with
simple, user-friendly operation.

manual is intended to give you an overview of all the possibilities and features of the
amplifier.
Enjoy your ATS 120!
Front panel control elements
(1) INPUTS:
sockets for connecting your instrument cable.
Nowadays, many different electric guitars are available, ranging from the classic Strat
with its "single coil" pickups to modern designs incorporating very high power active
humbucking units. To ensure that all types of pickups can be ideally matched to the
preamp of the ATS 120, two inputs are provided with different sensitivity ratings.
LO:
Input for guitars fitted with high output / active pickup systems.
HI:
Input for guitars fitted with traditional passive pickup systems.
The ATS 120's three channels
The Hughes & Kettner ATS 120 offers three separate channels, each of which has it's
own distinctive sound characteristics. The individual channels offer a wide variety of
different sounds thanks to their independent GAIN / VOLUME controls and
equalisation sections.
Selecting a channel
Above the individual VOLUME or GAIN control of each channel (Clean - Volume,
Crunch - Gain and Lead - Gain) there is a pushbutton which is used to activate it.
The active channel is indicated by an arrow-shaped LED. When using the CRUNCH
and LEAD channels, different coloured LED arrows are used to indicate which GAIN
and MASTER controls are operational.

  • Page 9 Care of your amplifier and guarantee conditions A WORD ABOUT VALVES: Valves need to reach a certain operating temperature. They need a few seconds after the power has been switched on to warm up before they will work. Valves are sensitive to shock. Once you have switched the amplifier off, give it a few minutes to cool down before transporting it.
