503BG
Gooseneck Microphone
|
Developed for computer voice
recognition applications, the 503BG gooseneck microphone offers
excellent voice fidelity while reducing background noise. Also use
the 503BG microphone in other close-talking applications such as
paging and talkback. |
|
| Features |
The 503BG gooseneck microphone
features a low-impedance, moving coil type transducer with an
integral humbucking coil and an attached two-conductor shielded
cable with a built-in strain relief. It produces a frequency
response with an essentially constant output voltage over the voice
spectrum when used close to the sound source.
The 503BG's case is aluminum with a black enamel finish. It mounts
to a gooseneck (not included), a fixed pipe or a microphone stand
using a standard 5/8"-27 thread.
- Optimized performance in voice
processing and computer voice recognition
applications
- Smooth frequency response with
excellent fidelity in the voice range
- Cardioid pickup pattern and
close-talking operation keep unwanted signals and background noise
at low levels
- Constant output over voice
spectrum when close talked
- Humbucking coil minimizes
undesirable hum effects such as CRT interference
- Low-impedance design permits
long cable runs in extreme hum fields
- Small unobtrusive design does
not interfere with CRT visibility
- Frequency response: 100 to 7,000
Hz

- Acoustic Considerations
The 503BG maximizes performance in close-talking applications
through its tailored frequency response, directionality and
distance discrimination. It optimizes and controls sounds within
the 100 to 7000 Hz frequency range and reduces sounds outside that
range. The 503BG rejects noise through its inherent directional
properties and discriminates against distant sounds in favor of
close-range sounds.
