    Sennheiser MZA900P reviews

    MZA 900 P - In-Line Preamplifier is rated 4.6 out of 5 by 22.
    Rated 4 out of 5 by from Works With Countryman I purchased the MZA-900 convert my Evolution-wired Countryman B3 microphones for hardwire use. The MZA-900 works a treat. All you need is Phantom power, 12V or 48V... If you're using a mixer like a Sound Devices 302 the B3 (& the supplied Sennheiser ME2 microphone for that matter) will happily run on Phantom 12V; as apposed to 48V. I find that the mixer batteries are put under less pressure & last longer when running mics at 12V instead of 48V. The MZA-900 is a tad expensive for what it is but far cheaper than purchasing an additional standalone hard-wired microphone. It also makes much more sense to have a dual-capability microphone (hardwire & wireless) as apposed to two separate mics. A worthwhile purchase.

    Rated 5 out of 5 by from Adds versatility to my mics I use this for everything from a Sanken COS-11 to a Tram TR-50. If our Sennheiser G3 systems are getting too much interference (90% of the time), we yank 'em and use this to hard wire the mics. Very simple to use.

    Rated 5 out of 5 by from Piece of Mind Love having this in my audio kit. Enables me to build my inventory of quality wireless lav mics and have the flexibility of using them as wired mics when needed. Using the same lav mic for wired or wireless scenarios provides a consistent sound quality to a project. It also saves space in my cases as I don't have to carry multiple wired lav systems.

    Rated 5 out of 5 by from Won't be without one....or two I've owned one of these since I first got my Sennheiser G2 wireless kit. There are times when I don't want to deal with wireless glitches and I want the simplicity of a wired connection. I now own two of these and wouldn't go on a job without them.

    Rated 4 out of 5 by from Great, but overpriced I love how well this works. It sounds great. It's solidly built. But the price? Come on, Sennheiser.
    Date published: 2018-07-07
    Rated 4 out of 5 by from valuable problem-solver I bought this to convert a Sennheiser ME3 headset microphone to wired, phantom-powered use. It's a kind of expensive solution for that but it's the solution most likely to be plug-and-play and dependable. Plus its usefulness as a test tool for phantom-powered mic cables gives it the added value which (to me) made it a worthwhile investment. As a mic interface the MZA900P works as advertised, and seems to be at least up to the sound quality level of the Sennheiser ME3 mic. There is a tiny bit of noise in the mic signal but I suspect that is due to the small-diaphragm mic element of the ME3, not due to the MZA900P circuitry. I do not have any other compatible and comparable mics handy to directly plug in and compare for noise levels. Physically the adapter is compact and lighter than I expected. It is NOT heavy and clunky like a Shure inline mic transformer. So it clips nicely onto the performer's belt or clothing and seems willing to stay put. The spring-metal clip seems durable. A compatible Sennheiser mic will attach securely to it with the threaded collar built into the mic's plug. Depending on the performance situation that secure attachment feature could be critically important and valuable. I left one star off my rating due to its relatively high purchase price. Other than that it seems to be a 5-star product.
    Date published: 2010-03-25
    Rated 5 out of 5 by from Works as Advertised I shoot weddings with two two Sennheiser wireless G3 kits. I needed a way to do simple non-wedding interviews using the Sennheiser mikes. The MZA 900P is the perfect solution to adapt my camcorder's phantom power for these mikes. It is so small I leave it connected to my XLR cord and cary it with me in my camera bag. If I ever encounter radio interference I can't avoid by switching frequencies, I'll have a backup solution for weddings too.
    Date published: 2013-03-18
    Rated 4 out of 5 by from Works Great! This item gets the job done. It lets me go wired when I don't want to (or can't) go wireless. I like the size of this item. Small enough to fit into the mic case, but not so small as to make handling difficult. Easy to use, and (so far) trouble-free. The only downside is the price. The price seems rather high for what it does. But ... as there seem to be very few alternatives on the market, that's how it goes. Recommended
