![]() Thanks to our modifications, the CS Binaural mic set has a dynamic range of over 90 dB. This is comfortably below the noise level of the Sony DAT and MD recorders' microphone pre-amplifiers and the ambient noise level at concerts. Their noise level is typical of 1/4-inch electret condenser microphones, approximately 30 dBA. The microphones are nominally omnidirectional but their pickup pattern is modified by the absorption and reflection characteristics of your head and outer ears. Sensitivity of the modified cartridges is approximately -66 dB (0 dB = 1 Volt per microbar). We match the pair to within one dB of each other. After modification, the modified cartridges sound better than that, typically within 1 dB from 20 to 20,000 Hertz. Typically they are within 1 dB up to 20 kiloHertz and down less than 5 dB at 30 Hertz. The modifications add more than 20 dB to the microphones' undistorted dynamic range, flatten and extend their low frequency response, and all but eliminate recorder overload distortion.īefore Core Sound's modifications, the Matsushita cartridge's frequency response is specified flat within 1 dB from less than 40 Hertz to more than 15 kiloHertz. They are electrically and mechanically modified to provide a more linear sound-to-voltage transfer function and to eliminate mechanical resonances in their bass response. The CSB microphone sets are based on a pair of Matsushita (Panasonic) miniature omnidirectional electret condenser cartridges. Another user clips the microphones to the shoulders of his jacket. This fellow clips his microphones to the light grid over his club's stage. One user says that this configuration provides excellent stereo imaging. ![]() The microphones can also be used as a classic stereo (not binaural) "spaced array" with each microphone placed eighteen inches to two feet from the other. ![]() This copies the human ear, ensures a true binaural pickup pattern, and accurately captures sonic information coming from all directions. 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.įor binaural recordings the cartridges are aimed outward (not forward) much as your ears are. If necessary, the cable can be easily split for its entire length, so that the microphones can be separated as much as 12-feet apart. (October 4, 2002: A high quality right angle plug is now available as an option.) The cable runs for six feet and terminates in a high reliability, 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 straight 1/8" (3.5mm) phone plug - other connectors can be supplied on request. The cables from the two microphones join into a single cable roughly twelve inches from the microphones. You can use velcro strips, double sided foam tape or whatever you can dream up!Ī very flexible shielded cable exits the base of each tube toward the rear of your head. They have no alligator clips so you have to be creative about how you plan to mount them. This allows you to easily insert the microphones into a set of elastic eyeglass holders ("Croakies"), sew them in a bandana or mount them in a hat. The removable clip sits on a black nylon disk that snaps into and out of the microphone shell.įor the bottom cable option, the cable enters the shell from the bottom of the shell, on the surface opposite the microphone face. The fixed clip is permanently fastened to the microphone shell. The alligator clips are finished in black and their handles are covered with a pliable black plastic. The clip can be used to attach the microphones to any convenient mounting surface, including your eyeglasses, lapels, collar, shoulder, hats, headband, lighting grids and many others. We now offer three mounting options: two for the side cable entry and one for the bottom cable entry.įor the side cable option, the shell can have either a fixed (included in our standard mic set) or a removable miniature alligator clip (optional) attached to its base. The microphone cable can enter the shell in one of two locations: the side or the bottom. Removable black light-duty foam and heavy duty windscreens are optional. The black finish is heat-fused plastic and is much more durable than paint. ![]() Being all metal, the microphone mounts are very durable. 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. The two microphone cartridges are each mounted in their own satin-black metal shell. Binaural Microphone Description & Mounting Options
