MK:43x Variants
Two variants of the microphone system are available, with each meeting the type 1
requirements of IEC60651. The particular variant required is determined by the
instrument to which the microphone is to be connected. These options must be
specified when the microphone is ordered. The variants are designated by the
engraving of the preamplifier body, located at the top of the main body assembly.
Version
For use with
MK:437
CR:703B Sound Level Meter
MK:438
CR:800A Sound Level Meter
The MK:43x Outdoor microphone system is usually supplied with an MK:224 ½” Type 1
pre-polarized electret capsule, or may be specified without a capsule, allowing the
microphone of an existing sound level meter to be used.
The MK:43x is supplied with a windshield to reduce wind noise and to protect the
capsule from adverse weather conditions. The top of the windshield carries the
bird-spikes which prevent birds from landing on top of the unit, thus causing extraneous
noise as well as soiling the windshield. The unit is also supplied with an integral tripod
allowing the unit to be used as supplied.
Be very careful when using the bird-spike as it is at eye height.
