Desktop Microphone
EM195A
The EM195Ais a directional electret microphone. It is designed to be connected
to unbalanced microphone inputs with bias powering such as those found on the
Ampetronic ILD100 & CLD1 induction loop amplifiers. The unit is directional, so it
can reduce unwanted sound pickup from sources that are not
in
front
of
the
microphone.
Restrictions
on
usage
The EM195Ashould not be directly connected to balanced
or
line level inputs. It
should onlybe connected to inputs intended forunbalanced electretmicrophones
with DC bias power.
1.
Mounting
The microphone should be placed so that it points towards the wanted sound
source (e.g. the receptionist at a counter) and is reasonably close to that source.
Take care to ensurethatthe microphonedoes picknotup unwanted sounds when
choosing whereto putthe unit.

2. Outputconnection.
The EM195A is terminated
in
a 3.5mm mono jack plug. This should be plugged
into the microphone input
of
the ILD100
or
CLD1.
To
connect the EM195A to a
balanced microphone input, the Ampetronic
MAT1
adapter should be used with
phantom poweron the amplifier.
Any extension up to 3 metres total cable length should be made using a
screened cable and good quality connectors. Underno circumstances should
the output cable be extended beyond a total length
of
3m as the extended
connection would be susceptible to interference. The output via the
MAT1
can
be extended using balanced cables with XLR connectors without length limits
