GENERAL INFORMATION
The MA-100 is a vacuum tube design and requires a dedicated power supply and seven-pin cable
set for operation. These items are provided with the microphone, along with a specially designed
shock mount assembly. The capsules are 3-micron, gold-sputtered types, with a interchangeable
cardioid and omnidirectional pick-up patterns. The vacuum tube head-amplifier delivers wide
bandwidth and low noise operation. The MA-100 utilizes a sub-miniature vacuum tube, which
necessitates the need of a dedicated power supply. The vacuum tube is military grade 5840W
"new old stock" and will deliver excellent performance for many years. A specially designed,
high-quality output transformer delivers an isolated, truly balanced output signal, minimizing the
possibility of unwanted noise entering the preamplifier. As with all vacuum tube microphones, a
warm-up period is advised for optimum performance; usually about ten minutes.
SAFETY INSTRUCTIONS
WARNING!
To avoid electrical shock to yourself and damage to the MA-100, use proper circuit protection.
The MA-100 is normally wired for 115V, 60 Hz operation, however, export models are wired for
the voltages of the country to which they are exported to and this information is duly noted on
the outside of the box as well as on the bottom of the power supply. The MA-100 uses a line fuse
for protection. Never replace this fuse with one of a higher current rating. Use only that type
which was supplied with the unit. The power supply cord that is supplied with your MA-100 is a
standard “business machine” type and should be examined regularly for defects in the insulation.
Never use a cord that has damaged or exposed wires.
There are no user serviceable components inside the MA-100 microphone or its power supply.
Always refer service to qualified technician equipped to service this equipment. Never expose
the MA-100 microphone, its power supply, or cable set to water or any environment that may
create an unsafe electrical hazard. In the event of a malfunction, disconnect the MA-100
immediately and determine the nature of the malfunction before attempting to use it again.
To avoid tripping over the microphone cable, make certain that the cable is not in the way of foot
traffic, or suspended in an unsafe manner. Make sure that the microphone stand is secure and not
likely to fall.
If you have any questions or concerns about operation of your MA-100 please contact the
factory.
