PRODUCT INFORMATION CK 930 / CK 950
Thank you for selecting the CK 930 / CK 950 microphone. Please
take some time to read carefully through this product information
before using the microphone.
Safety Information
• Protect the microphone from moisture and sudden impacts to
prevent damage. You could either injure yourself or others.
Application
Due to the cardioid or supercardioid polar pattern both
microphones, the CK 930 and CK 950 provide a high gain before
feedback and excellent intelligibility of speech. Therefore, they are
suitable for miking speech when used with podiums or pulpits as
well as miking instruments such as violins or acoustic guitars.
Depending on the applied accessory (partly optional available), the
CK 930 / CK 950 can be placed on a table or pulpit, mounted on
a microphone stand with 3/8" thread or it can be used for a
hanging installation from a ceiling.
Powering
For powering these microphones need a phantom power between
11 and 52 V. The CK 930 / CK 950 is powered via the CV 900
power supply.
Connect one end of the MVK 900 cable to the 4-pin male mini XLR
connector of the microphone and the other end (5-pin female mini
XLR) to the CV 900 power supply. The CV 900 is connected to a
mixing console or amplifier with phantom power via a 3-pin male
XLR connector.
Pre-attenuation
Inside the microphone capsule the CK 930 / CK 950 provides a
switchable pre-attenuation. The microphone is delivered with the
pre-attenuation switched off (switch to 0 dB).
The switchable pre-attenuation pad allows increasing the maximum
SPL capability by 15 dB for distortion-free close-in recordings.
When the distance to very loud sound sources (e.g. acoustic
instrument amplifiers) is small, the pre-attenuation pad should be
switched to the -15 dB position.
Unscrew the microphone capsule by turning it anti-clockwise. The
pre-attenuation pad is on the underside of the circuit board. Please
refer also to the pictures 1 and 2.
Use the tip of a Biro
®
, tweezers or paper clip to switch the pre-
attenuation on (switch to -15 dB).

Switchable low-cut filter of the CV 900
The CV 900 power supply provides a switchable low-cut
filter.
If the microphone connected to the CV 900 is used for recordings
from a short distance, the result is a boost of the bass frequencies,
which is also referred to as proximity effect.
The low-cut filter (at 250 Hz with 6 dB/octave) compensates the
proximity effect which can occur with directional microphones
(if the distance is less than 4 inches (10 cm)).
