Earthworks P30/CMP-B Periscope #4911/4912 (Used) – No Longer Available

Matched pair of P30/C's in wood box - black finish

Product Description

The Earthworks P30/C is a directional prepolarized condenser High Definition Microphone™ with a first-order cardioid pickup pattern directly coupled to a dedicated wideband, low output impedance transformerless preamplifier.

The P30/C requires a standard 48V Phantom Power supply. It features a flat frequency response from 30Hz to 30kHz (Fig. 2), fast impulse response (Fig. 3), very low handling noise, uniform polar pattern, and high SPL handling capabilities. It provides excellent uncolored rejection of sounds arriving off-axis.

Each microphone is delivered with its own calibration chart providing the individually measured frequency response curve. A mounting clip is included with the microphone.

Earthworks P30/C is easy to operate. Connect the microphone to a microphone preamplifier supplying 48V phantom power using a standard XLR microphone cable. Please allow up to one minute for the microphone to settle. Plugging in the microphone “hot” (phantom power already present at the input) will not damage the microphone, and is actually preferred for faster settling. It is normal for any phantom powered mic to “pop” when plugged in or powered up. Make sure to mute the signal to speakers or headphones when phantom power is first applied.

The excellent performance characteristics of the P30/C give it a very wide range of application possibilities. With its 4-inch flexible neck and small microphone head, this highquality microphone could be placed where other microphones could not, such as under the strings of an acoustic bass. The P30/C is an ideal choice for recording or live sound applications using percussion, acoustic or amplified instruments, or choir when using microphone stands. It is superior for choir because it doesn’t spotlight; rather, it picks up an entire section with no hot spots.

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
