What We Think

Looking for a single-point LDC Large Diaphragm Stereo Mic for under $1K? Well, there's only one worth looking at. This impressive mic smokes all other LDC Stereo mics that we tested in this price range, and even gave a couple $3K stereo mics a run for their money. Incredibly simple to setup and begin getting a great stereo recording right away, the LSD2 is a great value, and a useful microphone to own. That being said, there is definitely some benefit to owning two separate individual mics that you can use separately or in stereo configuration- if you aren't necessarily after the single-point mic, then a pair of the Studio Projects C3's are an incredible deal. Two of those C3's are quite a bit less money, especially given their recent price reduction, and sound extremely similar to the LSD2. The advantage to the stereo mic is that you never have to worry about the difficulty of getting accurate stereo alignment in XY, M-S or Blumlein (figure-8's). That being said, the one drawback to the stereo mic, which would be the advantage of two multipattern condensers (like the C3), is that you are unable to achieve A-B stereo miking (spaced omni technique) with the single microphone, and also true ORTF (representing the small distance spacing of the human head). Either way, both configurations, whether you want a single point stereo mic, or simply a stereo pair, represent incredible values compared to what else is available on the market in a similar price range. Due to the slightly smaller diaphrgam on the LSD2 as compared to the C3, the LSD2 does seem to be a bit more detailed, and slightly better at capturing fast transients, and certain high frequency detail.

Manufacturer's Description from Studio Projects

The LSD-2 is comprised of two separate dual-membrane solid state microphones contained within a single housing. Its capsules are mounted in close proximity on a vertical axis - the upper capsule assembly having the ability to rotate 270 degrees horizontally, relative to the lower capsule. Two C&K three-way switches control the polar response, high pass filtering and -10dB pad for each capsule (The switches on the front of the body correspond to the lower fixed capsule, while the switches 180-degree opposite on the back of the mic control the rotating upper capsule). It is the combination of capsule articulation and independent pattern switching which allows a user of the LSD2 to achieve all manner of coincident pair stereophonic recording techniques. Due to the close proximity of the capsules, there is no phase cancellation resulting from time delay between the two signals. This translates into excellent mono compatibility.

The inner workings of the LSD-2 are essentially that of two Studio Projects Model C3 microphones. The capsules are 1.06" (27mm) diameter, dual membrane, Braunmuhl-Weber design. These are independently coupled through low-noise amplifiers based on FET driven discrete balanced output stages. The outer housing is plated brass with a single layer brass wire mesh grill surrounding the capsules.

Included with the LSD-2 microphone is a dedicated 7-pin XLR to dual 3-pin XLR "Y" cable, magnum-sized foam windscreen, standard shockmount and carrying case.

About Manufacturer

Many microphone manufacturers on today's market bring microphones in from Asia with their brand name on it. It's a very common thing, and they are all pretty good. Some buy all their parts from Asia and assemble them from down under somewhere. Other's go so far as to deceive you by making you think they actually make their own mics right here in the USA or other Country of origin. We won't mention names, but during our travels to many different manufacturers in Asia, we saw plenty of brands come off the assembly lines. Now not all brands do this, but many do. You need to know this. Not that the product is bad, but no one wants to be tricked! Studio Projects partner company, 797 Audio, has a long history (more than 40 years) in the production of professional microphones. The photos to the left and below are from their early 1950's models when their first vacuum tube microphones hit the market The company has a strong contingent of engineers engaged in electro-acoustic products and structural design. With a complete set of B&K electro-acoustic measuring instruments, a first class anechoic chamber, and a high level testing facility, Studio Projects microphones are manufactured at the highest standards available. You wont find real cool new ?buzz? words on this site, or stories of how long it took to create our mics from the latest and greatest materials known to both humans and little green men from outer space. We won't go into how passionate we are for our microphones by showing you our esteemed leader holding his microphone with a look of love in his eyes, as we think that is a bit kinky, and quite frankly, what has that got to do with microphones! After all, we are talking microphones here, and with so many on the market, why should you buy ours, especially since we are a new company? Well, that is a good question so let's address it. We think it's quite simple. Our mics are every bit as good or better at a fraction of the cost you would pay for a world class German microphone. No, we are not a German mic, but we sure do sound like those $3,000.00 models. We use an outstanding capsule based on a 1950's German design, but we have made it sonically better due to advanced manufacturing techniques. We know as much as about mics as any microphone company out there with the exception of what we charge for them. After all, PMI Audio Group knows good sound and by bringing Studio Projects in directly without the added middleman stepping all over the product, we can make them very affordable. If you're not convinced just yet, you will be soon enough. We have plenty of time to wait it out. So keep the Studio Projects name in the back of your mind as you have nothing to lose, and everything to gain. You see, we may be priced like the other low cost brands, but the quality and sound you get will compare with the expensive German models.
