The Shure In-Line Hi-Pass Filter rolls off low-audio frequencies to reduce 60 Hz electrical hum and low-frequency-wind-, air-conditioner-, stand-, and floor-transmitted low-frequency vibrations.

When loaded with a low-impedance microphone input (800 ohms or more), the roll-off is 12 dB per octave below 100 Hz. When loaded with 150 ohms, the roll-off is 3 dB at 100 Hz. The output is flat above the roll-off point (with a maximum loss of 0.5 dB at 1 kHz).

Provides low-end roll-off of 12 dB per octave below 100 Hz

Reduces unwanted low end rumble in microphone signals.

Slender, in-line XLR (F) to XLR (M) configuration

Requires use of balanced signals

Q: 1. How long is the flexible gooseneck ?

A: The Flexible gooseneck is about 3.3 inches in height.

Q: 2. Will this also fit the DJI RS2 ?

A: The Tilta Power Pass-Through Plate with V-Mount Battery Plate is not compatible with any of the DJI RS2 models.

Q: 3. What is the difference between Fethead Regular and Fethead filter?

A: On some microphones, a subject close up to the mic may have exaggerated bass frequencies. Although this can be desirable for some recordings, it may not always be what you want. The Fethead filter mic has a high pass (low cut) filter built in, which will cut frequencies below 220 Hz by 6 db/octave. The standard Fethead model (B&H # TRFETHEAD) will boost all frequencies evenly.

Q: 4. I'm running 50' of cable between our IEM Combiner and the Shure PA805SWB antenna. Will this amplifier work for this application?

A: The Shure UA834WB In-Line Antenna Amplifier would not be recommended for use with an IEM transmitter, as it is intended for use only with wireless microphone receivers. However, as long as your run is under 100' and you are using high-quality cable, there is no real need for an amplifier in this particular case.

Q: 5. What is the appropriate connector to go from this to the 3.5mm mic input of my Cannon vixia g50?

A: To connect the output from the Shure A15LA Line Adapter to the mic input on a Canon Vixia HF G50 Camcorder, you will need a cable with XLR 3-pin female and 3.5mm TRS male connectors like the Kopul XRSM 3-Pin XLR Female to 3.5mm RA Stereo Mini-Plug Cable - 1.5' (B&H # KOXRSM015B) or any similar cable with these connectors in the length you prefer.

Q: 6. Does this XLR barrel adapter block Phantom power (48v)? I tried a different brand and it only worked on mics that did not need phantom power.

A: No, the Shure A15HP does not block phantom power and it does allow phantom power to pass through so it can be used with condenser microphones as well as dynamic microphones.

Q: 7. What UV energy range (nm) does it pass?

A: The Rosco Double Coated UV Pass Permacolor Glass Filter - 2x2 transmits light between 360 nm ti 420 nm.

Q: 8. Are these sold as pairs? 2 antennas per RF kit, so want to be sure before ordering.

A: These are sold as single units.Simply connect the band-pass filter in-line with your wireless microphone remote antenna connections for 40 dB of side rejection. Note: (2) required for diversity wireless microphone systems.

Q: 9. Is there a version for RS4 Pro coming?

A: Tilta states that there should be an RS4 Pro compatible version of the Tilta Power Pass-Through Plate with V-Mount Battery Plate released soon.

Q: 10. Can this also be used for line level signal? ex: to a powered speaker

A: Yes, the Shure A15HP In-Line High Pass Filter can be used for line level signal. Even though its main use is for microphones, the A15HP can also be used for other audio applications to reduce low frequencies below 100 Hz.
