The SR77 is simply a real and natural sounding mic. It offers no hype, no warmth and no shimmer; instead, it provides total and complete accuracy. To be precise, the SR77 is the most accurate directional microphone I have encountered so far.
The SR77 ($599 each; $1,300 for a matched pair in a cherry box) is a small diaphragm cardioid condenser microphone requiring 48 V phantom power. At 6″ it is virtually flat, with a frequency response of 30 Hz to 30 kHz (+/-1.5 dB). It is approximately 9.25″ long with a 0.86″ diameter and a weight of 1/2 lb. Matched-pair SR77s include a pair of microphone clips and a windscreen.
I found the SR77 to be an amazingly flexible microphone, easily adaptable to a wide range of situations. The most impressive of these is recording piano. A colleague told me the SR77 is a great piano microphone, so the last several times I recorded the instrument I had the assistant engineer put up the pair of SR77s in addition to what the studio usually uses. In every instance the SR77s were the better sounding microphones.
I’ve also found the SR77 to be a fabulous mic for acoustic guitar, drum overheads, percussion, hi-hats and even electric guitar in several instances (the microphone can handle up to 145 dB SPL) .
The user has extreme flexibility to use miking technique to alter the final sound. Low frequency response is flat at approximately 6″. Moving the mic any closer to the sound source than 6″ increases the low frequency level and moving it further away than 6″ decreases it.
The frontal pattern of the Earthworks SR77 is wide and smooth. Where most cardioid mics begin to sound significantly different at 40 to 50 degrees off-axis, the SR77 does not noticeably change tonal balance until nearly 90 degrees. I found that by moving the mic closer or further from the sound source and turning the microphone off-axis, it was far easier to tailor the microphone sound for the specific situation than with other small diaphragm microphones.
The Earthworks SR77 is a great sounding, extremely accurate and reasonably priced small diaphragm cardioid microphone. It is well made and appears to be quite durable. A pair of SR77s includes a beautiful wood box that promises to keep the microphones in pristine condition for years to come.
