C 400 BL
Uses: Conference tables, lecterns, theaters, …
Features: Hypercardioid polar pattern, speech optimized frequency
range, extremely small, easy to place. Supplied with mounting plate
and special adhesive tape.
Benefits: Extremely cost-efficient unidirectional boundary micro-
phone for various applications. Its frequency response has been
designed for optimum intelligibility of speech. The design is incon-
spicuous and the housing can be painted easily in the color of your
wish. This makes it literally invisible.
C 680 BL
Uses: Conference tables, lecterns, places of worship.
Features: Cardioid polar pattern, shock mounted transducer, inte-
grated phantom power adapter. Supplied with special adhesive tape.
Benefits: Cost-efficient table microphone for inconspicuous place-
ment. The transducer shock mount effectively reduces impact noise
pickup. The supplied strip of special adhesive tape allows you to fix
the microphone temporarily on a table without staining the table or
leaving any residue after removal.
C 547 BL (T)
Uses: Theaters, places of worship, conferencing.
Features: Hypercardioid polar pattern, rugged construction,
switchable bass-cut filter for reducing footfall noise, studio-quality audio.
Benefits: The C 547 BL features a rugged, “non-crush” case
designed primarily for tough on-stage assignments. Other benefits
include optimum acoustic properties, high directivity, and neutral sound.
T-version without windscreen for table top use.

DISCREET ACOUSTICS MODULAR-SERIES
The Discreet Acoustics Modular-Series is a new modular back
electret microphone system. It comprises five capsule modules and
six installation modules (five gooseneck and one hanging module)
which can be used in any combination. The modules screw together
for extremely stable and reliable connections.
Applications include speech reinforcement and recording in
places of worship, conference centers, at panel discussions, etc.
STANDARD ACCESSORIES: WINDSCREENS
The CK 47 and CK 80 include the unchanged W 70 or W 80
windscreen, respectively. The CK 31, 32, and 33 capsule modules
come with a new, two-layer windscreen called the W 30. Two differ-
ent materials provide optimum rejection of wind noise. The dark
gray outer layer swirls the impinging air stream. The colored inside
layer is more permeable to air and acoustically neutral. It steadies
the air stream before it hits the diaphragm. This two-stage process
cuts wind noise extremely efficiently. W 30 and W 70 are also avail-
able in off-white.
INSTALLATION MODULES
All installation modules except LM 3 feature a status LED ring
normally powered off the phantom supply voltage. When the micro-
phone has been correctly connected and the system and phantom
power switched on, the LED ring will glow at medium brightness.
Thus, the sound system operator will know at a glance which micro-
phones have been installed correctly. Note that in this configuration
the LED ring only indicates the system is ready to operate (NOT that
the microphone is open!). However, all installation modules except
for the E versions allow the LED ring to be powered from an external
supply for “open mic” indication. In this mode, the LED ring will light
much more brightly to alert the talker that their mic is open. Where
neither of these functions is desired, the user may deactivate the LED
ring altogether. This allows you for the first time to select status indi-
cator modes without having to buy a new microphone.
