1. The Microphone
The
SOLIDTUBE
was developed because of the great demand for
the so-called “tube sound” in a price range suitable for many people,
to which it goes without saying that our special know-how in the pro-
duction of large-diaphragm microphones has had its influence.
It should be stressed at this point that the vacuum tube used with its
inbuilt heater element is significantly more sensitive to mechanical
shocks than is transistor technology. Therefore, the user of this
microphone should always exercise the greatest care and attention.
Even shocks caused by falls from low levels can lead to the breaking
of the hot heating element and, consequently, to the total failure of
the microphone. It is advisable, therefore, to buy and keep in reserve
a spare tube which you can get in any good music shop which sells,
for example, guitar amplifiers, or in the next AKG Service Center.
The microphone incorporates an ECC 83 (12AX7) vacuum tu-
be. Be sure to use replacement tubes of the same type only.
IMPORTANT SAFETY INSTRUCTIONS
Please read, follow and keep these instructions for later con-
sultations. Please heed all warnings for your own safety!
Do not block any ventilation openings on the power supply
unit and do not install the unit near any heat sources such as
radiators, heat registers, stoves, or other apparatus (includ-
ing amplifiers) that produce heat!
Do not use this device near water!
Clean the power supply unit from time to time with a damp
cloth only!
Do not defeat the safety purpose of the grounding type plug on
the power cord! A grounding type plug has two blades and a
third grounding prong. This third prong is provided for safety.
When the provided plug does not fit into your power outlet,
consult an electrician for replacement of the obsolete outlet.
Should another type of power plug be usual in a country in
which the unit is to be operated then you should buy and use
in that country a complete power cord which complies with
the international safety regulations and which has a plug with
device grounding!
Protect the power cord from being walked on or pinched par-
ticularly at plugs and convenience receptacles.
Use only attachment/accessories specified by the manufac-
turer!
Unplug this apparatus during lighting storms or when unused
for long periods of time!
Refer all servicing to qualified service personnel. Servicing is
required when the apparatus has been damaged in any way,
such as power-supply cord or plug is damaged, liquid has
been spilled or objects have fallen into the apparatus, the ap-
paratus has been exposed to rain or moisture, does not op-
erate normally, or has been dropped.
CAUTION:
RISK OF FIRE!
Should the fuse in the power supply unit ever be damaged,
replace with the same Type "T 0.125A, 250V" fuse!
