User's Manual
Technical Description
connector (see Fig. 3). The 0dB/20dB attenuation allows the 4011 to be used
for close-miking high SPL sound sources without the output of the micro-
phone overloading the console input amplifier. Types 4012 and 4011 use state
of the art low-noise preamplifier technology and are driven with unity gain.
All microphones come with an individual calibration chart of the self noise,
sensitivity and the individual frequency response.
The Passive Connection Converter
The PCC4000 Passive Connection Converter is an optional accessory, that
makes it possible to run High-Voltage Microphones on standard 48V phantom
power with reduced microphone specifications. The maximum reduction of
the microphone SPL handling capability will be 13dB and it is possible to
drive up to 100m of cable with the PCC4000 with the same specifications.
Like the High-Voltage Microphones the PCC4000 is transformerless. The input
connector is a modified 4-pin female XLR for connection directly to the micro-
phone. The output is a standard 3-pin male XLR-connector for connection to
standard cables.
Important: The microphones will only live up to their specifications if
powered correctly.
