Each Core Sound microphone cartridge is mounted in its own satin-black metal shell. The shell is approximately the size of a jelly bean: roughly a quarter-inch (.6 cm) in diameter and a half-inch (1.2 cm) long. Being all metal, the microphone mounts are very durable. Removable black foam windscreens are provided.

We offer two mounting options: with a clip or without a clip.

The microphone with a clip has a miniature alligator clip attached to its base; the cable exits from the side of the shell. The clip is used to attach the microphone to any convenient mounting surface, including the soundhole, a bridge pin, the bridge itself, an internal brace, a microphone stand, the back of a chair or anything else that works! The alligator clips are finished in black and their handles are covered with a pliable black plastic.

For the clipless microphone the cable exits the shell from the bottom of the shell, on the surface opposite the microphone face. They have no alligator clips so you have to be creative about how you plan to mount them. You can use velcro strips, double sided foam tape or whatever you can dream up!

Our microphone cable is made especially for us. It's very flexible and durable. It's very well shielded against electromagnetic interference and is a flat black color.

We offer both single microphones and matched microphone pairs.

For single microphones, the cable from the microphone runs for ten feet (other lengths are available) and terminates in a multi-pin locking connector for the connection to the battery box. Also connected to the multi-pin connector (in a "Y") is a two foot cable terminating in a gold-plated mini 1/8" (3.5mm) phone plug. Other plugs (e.g., gold-plated 1/4" phone plug, XLR plugs) can be supplied on request.

For microphone pairs, the cables from the two microphones join into a single cable roughly twelve inches from the microphones. (The distance can be adjusted with a collar on the cable.) The cable runs for ten feet (other lengths are available) and terminates in a multi-pin locking connector for the connection to the battery box. Also connected to the multi-pin connector (in a "Y") is a two foot cable terminating in a gold-plated mini-stereo 1/8" (3.5mm) phone plug. Other plugs can be supplied on request.

If necessary, the cable can be easily split for its entire length, so that the microphones can be separated as much as 20-feet apart. This is especially useful if you use the microphones for interviews: one microphone can be mounted on the interviewer and the other on the interviewee.

The microphones are powered by a battery box. The battery box contains a common nine volt "transistor radio" alkaline battery, associated electronics (top quality metallized polypropylene capacitors hand matched to 1%, and 1% metal film resistors) and a high reliability, locking multi-pin connector. The battery box itself is roughly half the size of a cigarette pack, is made of sturdy die cast aluminum, and is finished in a durable black crinkle finish. The battery lasts approximately 500 hours when powering two mics and should be replaced at least once a year. The battery box can power up to two mics simultaneously.
