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.
