Depth, presence and master controls are common to the three channels.
Depth controls the reactivity and consistence of low frequencies; presence controls the
width and freshness of mid-highs. Master controls the level at the input of final stage, after
pre section and effects loops. Thanks to this pot and to the final stage transparency, it's
possible to put under pressure the preamp stage also at low volume: despite of high output
power, X100M has been projected keeping in mind a very diffused needs, that is to have a
fully satisfying sound also at low levels.
Use, maintenance and periodic checks.
X100M use requires normal attention as in any other tube power amplifier. Top and rear
grids must be free for air circulation and correct cooling of internal parts.
Wait for at least two minutes after switch on before go in active mode, in order to allow
tube heaters reach the steady state.
Cabinet can be cleaned with a soft, cotton cloth wet with normal water. Avoid use of
aggressive solvents.
As for all the other amplifiers, if X100M is used often on stage and it is transported
frequently, with deep vibrations and shock, periodically check the tube insertion, screws
lock of frame and internal parts, bias and power supply voltages.
Warning: controls on the internal parts must be done only by qualified personnel.
For any doubt and before any service, please refer to MGD for information.
Tube replacement and bias set.
X100M is equipped by factory with selected tubes. The seven ECC83/12AX7 last a lot of
months and their replacement does not require any re-tuning.
