MXL 770 vs MXL 990: Let’s end this debate

Design and build quality

To get on with the proceedings, let’s peep into the physical aspects of both the microphones and see which one of them woos us with its looks!

The MXL 770 has a black color body with a matte-like finish and the front and lining are golden, giving it quite a classy look.

Inclining towards a more dampened lustrous end, the MXL 990 has a silver or champagne exterior body coloring with the lining and fonts in black.

Dimension wise, both the MXL 770 and the MXL 990 are fairly similar with minor differences. The MXL 770 is the longer of the two, while the MXL 990 is more broad and weighs a bit more as well.

The build quality of the MXL 770 and the MXL 990 is quite similar as both of them have a full metal body construction featuring a metal grille.

They showcase an almost weightless body type in-spite of being incredibly durable although they contain a majority of plastic materials. A proper use with the necessary accessories can eliminate the possibility of any potential damage.

The light-weighted design further broadens the scope for its versatile usage irrespective of whether you chose to hold the microphone or place it on a stand.


Any instrument that comes with a handful of features is always a matter of delight for the user and that’s exactly what the MXL 770 and the MXL 990 has to offer!

One of the most significant feature of MXL 770 and the MXL 990 is that both the microphones are based on a transformerless output system.

Couple of features work together significantly in achieving a wider dynamic range and eliminate any kind of buzzing noise and feedback.

The difference begins when we look at the polar pattern of both the microphones.

On one hand, we have the MXL 770 sticking to the conventional cardioid polar pattern picking up the signal from the front and cuts off any sound coming from the sides and specifically from the rear.

Thus, it is less likely that the MXL 770 will pick up much of any ambient noises.

While on the other hand, the MXL 990 showcases a 90 degree X/Y stereo polar pattern, which means it can be really useful in re-creating a more realistic sound imaging.

However, this trait can make the MXL 990 a bit too sensitive as a result of which it is very much prone to pick up ambient noises.

That being said, both the MXL 770 and MXL 990 are likely to capture the subtle details in sound and hence, both the microphones are recommended to be used in acoustically treated environments for the best possible output.

Moving on, with the MXL 770 you get a switchable high pass filter which attenuates at 150 Hz by 6 dB per octave and also a -10 dB pad switch.

These characteristics of the MXL 770 contribute massively towards reducing the low-frequency noises, especially caused by breathing and wind vibrations.

In addition to that, it also boosts the mid range and treble which increases the presence in the vocals or acoustic instruments.

There is no high pass filter switch in the MXL 990, but you can get a three-way positionable pad switch, where you can select between Hi (0 dB), Medium (-5 dB) and Lo (-10 dB).

Other complimentary features include a shock mount and a carrying case.

Lastly, both the MXL 770 and the MXL 990 are powered through a 48 volt Phantom power and XLR cables are used to connect them with mixer boards or interfaces.

Sound and Performance

Though both the MXL 770 and MXL 990 house a 6 micron gold-splutter low distortion diaphragm and have a similar frequency response range, the MXL 990 tends to sound a bit more flat and neutral with minimal coloration to its audio reproduction.

In simpler words, it doesn’t mess with the originality of the sound and doesn’t alter the tone. It has smooth high ends as well as the lows and mids sound solid and tight.

Meanwhile, the MXL 770 adds a little extra warmth to the sound and delivers an enhanced clarity to its high-end sound. With the high pass filter switch on, the midrange becomes more prominent while minimizing the low noise.

Keep in mind that both these condenser microphones are meant for professional use and they specialize in picking up the most intricate details of sound.

While the MXL 990 has an incredibly well-balanced and rich soundstage with a highly noticeable bass undertone, the MXL 770 excels in wider range of performance and offers immaculate clarity.

Adding to the list of differences, the MXL 770 is capable of handling louder sounds better than the MXL 990, thanks to its increased maximum sound pressure level handling capacity.

Pros and cons

  • Nice fullness and warmth to vocals
  • Crispy and clear highs, punchy, and tight lows

To sum it up,

Let’s just take a moment and appreciate the performance put up by the MXL 770 and the MXL 990 before we pen down the verdict because they both deserve it!

Now, the difficult part after such a close competition, is our verdict. It has to be the MXL 770 and there’s a couple of reasons to it.

Firstly, the high pass filter comes really handy in improving the sound quality. Secondly, it has a warm sound and it doesn’t get distorted while handling loud sounds. And thirdly, the price factor.

The MXL 770 is cheaper than the MXL 990 and since it has so much to offer at a lower price, it’s definitely a go from our side! The MXL 990 is a fabulous microphone overall but it’s not as good as the MXL 770!
