3. CONTROL ELEMENTS
The MIC INPUT connector is a balanced XLR microphone
input.
Connect your instrument to the INSTR(UMENT) INPUT
jack, using a standard instrument cable equipped with 1/4"
TS connectors.
The MIC VOL(UME) control determines the volume level of
the microphone channel.
The INSTR(UMENT) VOL(UME) control determines the
volume level of the instrument channel.
Use the CD INPUT to connect the output of your CD player,
tape deck, CD or MD walkman. This way you can play
along to music or guitar tutorial CDs.
This connector is a 1/4" TRS jack. If your CD player is
equipped with cinch outputs, youll need an adapter cable,
which you can buy at your local music shop. Illustration 4.4
in chapter 4. AUDIO CONNECTIONS shows you what
kind of adapter to buy. You can also use a mono cable
(fig. 4.5). This will not damage your CD player or amp.
The LOW control allows you to boost or cut the low-
frequency range.
With the MID control you can boost/cut the mid-range
frequencies.
The HIGH control adjusts the high-frequency range to give
your instrument a more cutting sound.
The HEADPHONES jack is for headphones. When you
plug in your headphones, the built-in loudspeaker is muted.
+ The headphone signal can also be routed to a mixing
console or sound reinforcement system. Connect
the headphone output on your AT108 to the line
input (LINE IN) on the console (for example,
BEHRINGER EURORACK UB1222FX-PRO). Please use a
mono cable for this application.
+ Some headphones produce distortion if the volume
level is too high. Please cut back the volume control
until the distortion disappears.
Use the POWER switch to switch on your AT108. The
POWER switch should be set to Off before you connect
your amp to the mains.
+ Please note: The POWER switch does not disconnect
the unit from the mains. Unplug the power cord
when you dont want to use the unit for some time.

No matter which way you adjust the controls on your amp: the
sound of your instrument or microphone also has some influence
on the overall sound. We would therefore like to give you a few
tips to get you started.
+ Most guitars sound best when their tone and
volume controls are turned up as much as possible.
Experiment with the controls to find out how you can modify
the sound to your liking. Experienced guitarists write down their
favorite settings or attach stickies underneath the controls.
