ADK S-51 Mk 5.2 Cardioid Condensor Microphone

I have been pleasantly surprised with this microphone on drum sources. I have used it on overheads for a couple months now and have found it to be less shimmery than other under $200 microphones I have tried. While I found it to be thinner in the mids than an Audio Technica 2035, those mics are know to sound more "in your face" in the mid-range. As compared to the 2035 I found the high-end nice and crisp without being harsh. I have also compared it with the Rode NT4 (stereo X-Y) and the ADK was the clear winner. The ADK captures the transients nicely on the cymbals and the attack of the toms are also tight. When trying out the NT4, I had several intances of "phasy" attacks that I just couldn't correct with mic placement. I have found the ADK S-51 was much quicker in finding the sweet spot.

Regarding the mic hardware, you get a roll-off switch and 10db pad. I leave the pad engaged for overheads and actually choose to leave the roll-off disengaged. I find the low end is not muddy at all and has very little need for roll-off. The only drawback I found was the lathing on the threads and the included clamp were a little off and required a bit of force to get setup... but I haven't had a problem after that first incident.

The case included is extremely nice wood and velvet, particularly at $173 that I paid for these mics. Not a bad touch at all ADK... your making me feel like a king! Overall, I have been very satisfied and would highly recommend the S-51 to anyone interested in drum, bass guitar, or other microphone needs where high SPL is required.

Here goes the product marketing material:
