BOOST MODE
TUBES
POWER SELECTOR
The BOOST MODE allows for instant
increase of volume level during a
performance. The potentiometer and a
foot-switch BOOST are designed to control
the BOOST MODE. The BOOST function
performs two features at the same time: it
boosts a signal at the input of the preamp,
giving extra compression and raising the
volume.
Desired volume level
may be
adjusted by tweaking the potentiometer. By
then pressing the BOOST switch located on
the top of the amp, two different volume
levels previously set will be obtained. The
BOOST MODE is quite beneficial as it
heightens the guitar solo during a live
performances.
The amplifier automatically adjusts its
operating parameters and can serve
4, 8 and 16 Ohm cabinets.
The amp can also be used without a
speaker cabinet. If so, the power amp is
automatically locked (LINE OUT is active only).
The amplifier is equipped with a 4-way power
output selector. It allows you to use speaker
cabinets of any size, power and impedance.
The following power options are available:
12W, 20W, 40W and 90Wat.
Optimal operating parameters of tubes 12AX7 are set during amp's manufacturing
process. The characteristics of each tube in the amplifier is individually tuned at MTD
system (Master Tube Design), to achieve the best performance possible. It is not
recommended to replace the tubes. Replacing working tubes with some other brand
will not improve the sound. The 12Ax7 are already tuned to perform at maximum
capability. Only broken tubes should be replaced.The tubes in MTD technology
works in perfectly designed environment which allows them to have very long life
span. If not mechanically damaged there is no reason to change them for years
