| DPA d:dicate™ 4004 Reference Microphone, 130
V |
|
Product Code:
4004
|
• measurement
microphone
• unbeatable dynamic range
• close miking recording situations regardless of the sound
source
• specially designed to handle extremely high sound pressure
levels
The 4004 is an omnidirectional hi-voltage (130 V) close miking
specialist with an extended on-axis frequency response from 10 Hz
to 40 kHz (±2 dB).
An ideal measurement mic, the 4004 is a reference condenser
microphone specially designed to handle extremely high sound
pressure levels - up to 168 dB SPL before clipping occurs.
It has an unbeatable dynamic range of 124 dB from the noise floor
to 1% THD and an extended headroom of 20 dB up to clipping level
due to the special hi-voltage powering system.
The 4004 is acoustically identical with the reference microphone
Type 4007, but differs in the powering system and the fact that the
4004 has a transformerless output.
4004 is totally transparent and is the perfect choice in all close
miking recording situations regardless of the sound source.
