The high-voltage powering system enables the microphone preamplifier
to handle approximately 10 dB higher sound pressure level than similar
microphone types powered through conventional P48 systems (4012
and 4016: 168 dB SPL peak, 401 1-TL and 4015-TL: 158 dB SPL peak).
The 4011-TL, 4012, 4015-TL and 4016 together with the HMA5000
are transformerless. All 4 microphones use state-of-the-art low-
noise preamplifier technology and are driven with unity gain.
All microphones come with an individual calibration chart stating 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
48 V phantom power with reduced microphone specifications. The
maximum reduction of the microphone SPL handling capability will be
13 dB and it is possible to drive up to 100 m of cable with the
PCC4000 with the same specifications. Like the high-voltage micro-
phones the PCC4000 is transformerless. The input connector is a
modified 4-pin female XLR for connection directly to the microphone.
The output is a standard 3-pin male XLR-connector for connection
to standard cables.
Important: The microphone will only operate within its
specifications if powered correctly.
