Desktop Microphone
EM195A
The EM195A is 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 EM195A should not be directly connected to balanced or line level inputs. It
should only be connected to inputs intended for unbalanced electret microphones
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 ensure that the microphone does pick not up unwanted sounds when
choosing where to put the unit.
There are two options for assembling and mounting the EM195A.
(a)
Desktop base.
This is a weighted base for free-standing use. The microphone
stem fits into a pivot allowing the stem angle to be adjusted.
{b)
Attached to other equipment.
By using the self-adhesive base, the microphone
can be attached to the side of other equipment (e.g. a computer monitor). The
pivot and stem then attach to this allowing adjustment.

2. Output connection.
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 power on the amplifier.
Any extension up to 3 metres total cable length should be made using a
screened cable and good quality connectors.
Under no 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
