Microphone Pads: Any Tips?I don't have the Shure model numbers but can tell you the attenuator is an "H" pad It is five resistors forming the letter "H," with two resistors on each side and one across the middle You can get an XLR barrel adapter (female to male) and put the pad in there Use high quality film resistors (1 4 watt should do with at least 1% tolderance or lower) You would

Microphone Pads: Any Tips?Microphones working into a lower i p Z may exhibit more distortion (especially older models) Especially if they have a transformer or passive lo-cut, the frequency response may change, too Micpre's seeing a different source Z than the nominal 150-200 ohms may exhibit more noise (has to do with the "optimum source impedance" (OSI) of the first active stage) Effects
- inline mic pads, H or U?
H pads allow better control of the output (load side) impedance, but generaly have lower input (mic side) impedance A U pad has higher input impedance and lower output impedance
- Myth busters: In line pads decreasing 48V.
Myth busters: In line pads decreasing 48V There is an impedance issue, which will affect the way the mic loads the transformer of the mic pre, but at -15dB, which should be plenty to help with saturation, you're only going from 200Ω to about 150Ω, on a dynamic mic using the Shure pad You can also build your own pad, and use the appropriate value resistors to ensure 200Ω output, if you feel
- Thoughts about the Neumann KMA lavalier microphone
While doing some research on the net to buy a lavalier microphone, I found this intriguing old model, the Neumann KMA, made from 1969 to 1985 According to Anselm Roessler's book (Neumann, the microphone company), it's a FET microphone with a nickel capsule, an interesting association also found in the KM88 Even if it's probably tailored for speech recording, some users pretend that it can
- Mic Pre impedance matching- What Are The Rules? - ProSoundWeb
When you switch in the resistive pad to such a preamp, then the microphone will see a much more resistive load because the pad resistors interface between the microphone and the input transformer so the mic sees the resistors in the pad as the load Microphone output source impedance is a little bit more difficult concept to initially grasp
- Neumann U67 Reissue: Complete Tear Down and Analysis
That "pads down" the signals coming from the microphone, but not too severely, and it reduces the microphone's self-noise as well as any noise due to interference in the cable, exactly as much as it reduces the wanted signal
