Page 3: Technical Description
10dB higher sound pressure level than similar microphone types powered through conventional P48 systems (4012: 168dB SPL peak and 4011: 155dB SPL peak). Both the 4011 and the 4012 together with the HMA4000 are transformerless. The 4011 is powered via a standard P48 system and is equipped with standard 3-pin XLR-connector (see Fig. - Page 4 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.
