Sennheiser MZA900P Reviews

A necessity

By Phillip
Rated 5 out of 5
Date: 2021-01-04

This is absolutely needed to connect to the Sennheiser mics as well as the SENAL UEM-155-35H-BK Omni Earset Mic. I like 3.5mm connection. Very secure.

Must have tool at a price

Yes, they’re expensive but needed if you’re a professional seeking clean audio when wireless interferences are wreaking havoc. They work perfectly but knocking 1 star off for bending me over.

question

How is this product different than the Rode VXLR+ ? Voltage ? Impedance ?
Asked by: Don
The Rode VXLR Plus does not provide the same voltage that the Sennheiser provides. The Rode does 3-5v. For example: the Sennheiser ME 2 requires 7.5v. The Rode VXLR Plus would not supply that voltage.

I have a Zoom H6 recorder and want to use it with the Senheisser MKE-2 lav mic (which needs 7.5V). Would I need to turn the Phantom power on in the recorder to 48V?
Asked by: Peter
I’m using this exact setup. Yes, turn on phantom power, and it will work perfectly!

I have a MKE 2 EW Gold microphone I would like to convert to XLR. Description says this device works however specs says that it deliver 1.6V of phantom power. The MKE 2 EW Gold requires 7.5 V of power. Does this actually work?
Asked by: David
This adapter will convert a 3.5mm mic with plug-in power, such as the Sennheiser MKE2 to XLR, and allow it to work with 48 V phantom power.

Will this power a Sennheiser MKH 416 to connect to a rode wireless go II?
Asked by: Ben
No, the Sennheiser MZA 900 P In-Line Preamplifier and Power Supply for EW Series Microphones will not work to connect a Sennheiser MKH 416 Shotgun Microphone to the Rode Wireless GO II Transmitter. To connect a microphone that requires 48V phantom power to a wireless transmitter, it would be suggested to use a portable phantom power supply such as the Denecke PS-1A Portable Single Channel 48V Phantom Power Supply (BH #DEPS1A) along with an appropriate adapter cable on the supply's XLR output connection: https://bhpho.to/3vYUjr9

question

Do this devise will work with Sanken COS-11D XLR conector wired.To connect to Sennheiser G3 wireless system?.I will like to use my wired Sanken for wireless too, do this is possible?
Asked by: Ryszard S.
Hi!I do not know the Sanken COS-11D XLR, but from the specs of the Sanken COS-11D XLR it is clear that the Sennheiser MZA 900 P is not what you are looking for. The Sennheiser MZA 900 P is doing the opposite of what you need.
