Boundary Microphone
Q400
The Q400 is a directional electret boundary layermicrophone. It is designed to be
connected to unbalanced microphone inputs with bias powering such as those
found on theAmpetronicand ILD100 & CLD1 induction loop amplifiers. The unitis
directional when properlymounted, so it can reduce unwanted sound pickup from
sourcesthatare not
in
front
of
the microphone.
Restrictions
on
usage
The Q400 should not be directly connected to balanced or line level inputs. It
should only be connected to inputs intended forunbalanced electret microphones
with DC bias power.
1.
Mounting
Boundary layer microphones are intended for mounting on
a surface. The surface forms a part
of
the pickup pattern
of
the microphone. The surface should not be subject to
strong vibration as this can be picked up by the
microphone.
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 not pick up unwanted
sounds when choosing where to put the unit.
2.
Output connection.
The Q400 is terminated
in
a 3.5mm mono jack plug. This should be plugged into
the microphone input
of
the
or
ILD100
or
CLD1
To
connectthe Q400to 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. Using an Ampetronic MAT1,
output cable length can be extended using balanced cables.
