What We Think

Like the rest of the line, the C1 rivals microphones costing as much as five to ten times its price. Awesome for low-budget studios that demand high quality vocal recordings. It also doubles well on instruments and anywhere else you'd need a high-quality condenser. If you want to step up a bit, try checking out their C3, or possibly even their extremely fine T3!

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.
