PM-660U is an elegantly styled, compact desk microphone
for use in public address, paging and radio communication
systems. Ideal applications include restaurants, offices,
warehouses, transportation terminals, dispatch centers and
entertainment facilities. Its smooth, natural response provides
high quality voice reproduction and excellent articulation
to enhance the overall performance of your system. Compact
and lightweight, the PM-660U requires a minimum of desk
or counter space and is easy to handle.
To significantly reduce background noise
and feed-back, the PM-660U features a cardioid pick-up pattern
that is uniform over the entire frequency range. The dynamic
microphone element has a 600 ohm balanced output and the
microphone is supplied with an attached 8.2’ , four-conductor
cable with stripped wire ends. Two conductors are shielded
and are dedicated for the micro-phone signal. The other
two unshielded conductors con- nect to an auxiliary, normally-open
switch contact, used to activate external muting, priority
or relay control cir-cuits. The auxiliary switch contact
is closed by using the push-to-talk bar, which also turns
on the micro-phone by opening a second set of contacts that
nor-mally short the mic element. A locking lever is provided
to keep the push-to-talk bar in the “on” position when the
microphone must be kept open for an extended period.
A wire mesh grille protects the mic element
and incorporates an internal wind screen to reduce popping
noises from speech. Ideal for desktop or shelf mount-ing,
the integral microphone stand/base is fitted with four,
rubber isolated feet to reduce mechanical noise pick-up.
Constructed of high impact ABS resin, the microphone is
finished in a neutral dark gray with a prominent, orange
