VINTAGER AC108
3. CONTROL ELEMENTS
Connect your guitar to the INST(RUMENT) INPUT jack,
using a standard guitar cable with a 1/4" TS connector.
The GAIN control determines the volume level and the
amount of distortion. Use GAIN to adjust the amount
of distortion and the MASTER control to set the volume
level .
+ If the GAIN switch is not pressed, the GAIN
control is disabled. In this case, the volume can
only be set with the MASTER control .
The GAIN switch provides additional boost on the guitar
channel.
The BASS control allows you to boost or cut the low-
frequency range.
Guitar amps are optimally matched to the sound of guitars
by shifting the point at which middle frequencies are
lowered. Pressing the SHIFT button enacts this function.
The TREBLE control governs the high-frequency range to
give your guitar a more cutting sound.
Use the CD INPUT to connect the output of your CD player,
tape deck, CD or MD walkman, for example, to practice and
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 4.3
in chapter 4. AUDIO CONNECTIONS shows you what
kind of adapter to buy. You can also use a mono cable (fig.
4.4). This will not damage your CD player or guitar amp.
The MASTER control determines the overall volume of your
AC108. Whenever you press the POWER switch or unplug
your guitar, be sure to set the MASTER control to zero first.
Otherwise, a loud crackling noise may be produced, which
could damage your loudspeaker or even your hearing.
The HEADPHONE jack is for headphone. When you plug
in your headphone, 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 AC108 to the line
input (LINE IN) on the console (for example,
BEHRINGER EURORACK UB1222FX-PRO). You can also
use mono cables.
+ Some headphones produce distortion if the volume
level is too high. Please cut back the MASTER control
until the distortion disappears.
Use the POWER switch to switch on your AC108. The
POWER switch should be set to Off before you connect
your guitar 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 guitar
amp: the sound of your guitar 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.
