DPA Microphones Launches 4041-T2 and HMA5000Large diaphragm tube mic and two-channel hi-voltage mic amplifier (November 10, 2004)
DPA's 4041-T2 Large Diaphragm Tube Microphone
The 4041-T2, the latest entry into DPAs family of large diaphragm microphones, utilizes an updated 130V microphone preamplifier module based on the proven design of the classic MMP4000-T, incorporating a pentode vacuum tube driven as a cathode follower in a class A unity gain output stage. The ultra-high quality sub-miniature vacuum tube is heated by 6V supplied via the new HMA5000 Hi-Voltage Microphone Amplifier.
The 4041 family of microphones employ the world-renowned DPA model MMC4041 Omni directional 1 capsule. ?When low self-noise and high sensitivity are important, such as in the miking of vocals, strings or other acoustic instruments with large dynamics, the DPA large diaphragm microphones are the perfect choice, states DPA Microphones, Inc. President Bruce Myers. ?The solid state models are chosen when the most transparent and faithful reproduction is demanded, whereas the new tube version add a slight, but wonderful, musical coloration to the recording.
With an extremely low self-noise of typically 10dBA and a THD @0.5 at 120dBSPL peak, the 4041-T2 has an impressive dynamic range of approximately 110dB. The back plate of the capsule is polarized via the HMA5000 with 200V, providing extremely high sensitivity and SPL handling of up to 144dB before the onset of clipping. A flat phase design with a frequency response from 10Hz to 20kHz and a soft boost of 4 to 6 dB at 8kHz, the performance attributes of the 4041-T2 matches the characteristics of the legendary 4040 microphone.
DPA's HMA5000 Two-Channel Hi-Voltage Microphone Amplifier
A microphone amplifier with unsurpassed specifications, the HMA5000 is a comprehensive microphone power supply unit with 130V for the high-voltage microphone preamplifiers, 200V for capsule polarization and 6V for heater voltage in the 4041-T2 tube mic. One of the main advantages of using a high-voltage mic amplifier rather than a 48V phantom powered version is that it increases resolution and detail and provides an extended dynamic headroom of 10dB more.
?Together with one of our high-voltage microphones, the HMA5000 provides the most serious signal path from sound source directly to track, continues Myers. ?With an outstanding frequency range from 10Hz to 200kHz (+0dB/-1dB) and an extremely wide dynamic range of 140dB, the HMA5000 carries the clean and undistorted microphone pickup through the amplification link without any disturbance the finest challenge for a mic amp.
