Get all the clean gain you could ever need for the quietest mic sources with the AEA Ribbon Mics TRP3, a two-channel microphone preamp made in the USA by the same company known for its premium ribbon mics. This compact half-rack unit offers balanced XLR mic inputs and high-impedance, and low-noise circuitry, so it can yield optimal results with ribbon, condenser, or dynamic microphones.

Between the 12-position mic-pre gain and the continuously variable output level, up to 85 dB of JFET gain is available for each channel. Three LEDs are provided per channel for a clear indication of levels at -20, 0, and +24 dBu. Tame bass buildup and proximity effect at the push of a button with the low-cut filter, which cuts 3 dB at either 115 or 230 Hz, depending on your setting. The TRP3 includes an external universal switching power supply to allow operation in any country.

Q: 1. The rode NTG-2 has can power itself with a AA battery. Will that battery power transfer also the this Fethead or must the Fethead power come from the recorder? I would like to plug NTG-2/Fethead combo directly into mirrorless camera.

A: No, the battery power for the NTG-2 will not also power the TRITON AUDIO FetHead Phantom In-Line Microphone Preamp.

Q: 2. If I do not need phantom power, can I still use it without the battery?

A: The Saramonic SR-PAX1 Two-Channel Audio Mixer, Preamp, Microphone Adapter requires power from a 9V battery in all use cases for proper operation. Using the SR-PAX1 with the phantom power feature disengaged still requires power from the internal 9V battery source.

Q: 3. Is there any advantage to using this fethead when I already have my ntg3 connected to the nice preamps of a mixpre-d?

A: You will be able to use significantly less gain.

Q: 4. Most of these AD2022's are silver...any difference with this black one?

A: There is no difference between the black and silver versions of the Avalon Design AD2022 Microphone Preamp.

Q: 5. Works whit beta 87?

A: This would work with a Shure Beta87a.

Q: 6. Has anyone used this with 2-3 Sennheiser ew 112-p G3 lav mic's?

A: Haven't used it like that, but I've had it setup with 2 inputs for the about year and a half, plugged in and powered on 24-7

Q: 7. I plan to use this with an h4n zoom or h5 zoom or a tascam 60d , which fethead should I get, there is an in line and fathead regular or fethead phantom? please kindly clarify before I order. thanks!

A: It depends on the mic you are using. if your mic needs phantom power (condenser) then get the fethead phantom. If the mic does not need phantom power (dynamic) get the regular.

Q: 8. Is this adapter compatible with the Sony HXR-MC2500 camcorder?

A: Yes, the Saramonic SR-PAX1 can be used with any camera that has a 3.5mm mic input.

Q: 9. Is this the correct Fethead for the Deity S-Mic 2S? Or should I be getting the regular Fethead? (The S-Mic 2S is a phantom powered mic, but even still this isn't clear).

A: This is the correct model.

Q: 10. I know there doesn't seem to be any way to turn off the phantom pass through. Can you use this on dynamic mics like the Shure SM7b without any problem? Thanks.

A: The FetHead Phantom is only designed for condenser mics. The standard FetHead is designed specifically for dynamics such as the SM7B and ribbon mics as well.
