Brief Description
The C 562 CM is a boundary microphone designed to be installed in a sound
reflecting surface such that the diaphragm will be flush with the surface and
face the sound source. This prevents comb filter effects or other interference
that may arise when a microphone is placed close to a reflecting surface.
You can install the C 562 CM in a desk top, table top, wall, or ceiling. (In
order for the microphone to function properly, the microphone body should not
make contact with any grounded metal parts.)
The polar pattern of the microphone is approximately hemispherical. When
installed in a reflective surface, the C 562 CM’s sensitivity is 6 dB higher
than that of a convention al omnidirectional microphone. Using an
omnidirectional pressure transducer, the C 562 CM is much less susceptible to
mechanical and wind noise than a cardioid.
Fig. 1: C 562 CM and phantom power adapter.
Refer to fig. 1.
The C 562 CM comprises the flush mount microphone (a) with a 20-in. (50-cm) fixed cable terminated in a TS mini jack plug (b) and a separate phantom power adapter (c) with 20-in. (50-cm) fixed cable and female TS mini jack plug (d). The phantom power adapter features a low-impedance, electronically balanced output and can be connected to balanced or unbalanced inputs.
Powering
The C 562 CM provides low self-noise yet high headroom. The microphone requires a phantom power source providing 9 to 52 V as per IEC 61938.
- Do not connect the microphone to any power supply other than a phantom power source (input with phantom power or external IEC standard phantom power supply) with a floating connector, using a balanced cable with studio grade connectors to IEC 268-12 only. This is the only way to ensure safe and reliable operation.
IMPORTANT
Installation
You can install the microphone in a panel with a maximum thickness of 6/8″ (19 mm).
Fig. 2: Installing the microphone
in a boundary.
- To ensure proper functioning, make sure that the microphone body will not make contact with any grounded metal parts.
Refer to fig. 2.
- Drill a hole ½” (12.5 mm) in diameter in the boundary (a).
- Thread the cable (b) though the hole from the front and push the microphone (c) all the way in.
- Press the microphone (c) against the boundary (a).
- Slip the knurled nut (d) over the jack plug and cable and onto the microphone shaft (e).
- Tighten the knurled nut (d) to the point that the microphone (c) is firmly held in place.
The C 562 CM is small, easy to install, inconspicuous, and provides
outstanding recording quality. It is therefore an excellent choice for close-
miking people shying away from microphones and applications where no
microphone must be visible for visual or esthetic reasons.
Example 1: Theater stage miking
Fig. 3: Installation in stage decoration parts.
Refer to fig. 3.
- Install the microphone in a reflective wall (covered with no wallpaper of sound absorbing material) near the sound source. The wall should be as even and reflective as possible.
Example 2: Lectern or pulpit
Fig. 4: Installation in a lectern or pulpit.
- Install the microphone directly in the lectern or pulpit. Due to the wide pickup angle of the microphone, the talker is free to move without causing wide variations in signal level. Also, the microphone will be practically invisible.
Example 3: Conference room
Fig. 5: Installation in a conference table and ceiling.
Refer to fig. 5.
- In a conference room, you can install either a single microphone in a conference table or one or more microphones in a reflective ceiling panel.
More hints
Fig. 6: Minimizing sound pickup from unwanted sources.
- The hemispherical polar pattern may cause unwanted sounds from unexpected directions to be picked up. Unless the boundary is too large or permanently installed, simply turn the panel with the microphone away from the unwanted source.
Alternatively, you can place suitably sized (4x4ft. / 1×1 m) plexiglass panels or thick-pile carpet between the microphone and the unwanted sound source(s).
Fig. 7: Reducing mechanical noise.
- You can reduce mechanical noise to a minimum by placing a layer of sound absorbing material (e.g., soft foam) beneath the reflective panel.
