The black I2 Bass and Cello Microphone Kit with 3.5mm Locking Connector for Sony ZTX-B01 and ZTX-B02RC Wireless Transmitters from Countryman is a mic that has been built from the ground up for smooth frequency response, low noise, and precise polar patterns with deep nulls and natural on- and off-axis response. It can be used to capture natural audio for this instrument.

The I2 microphone is suitable for distance miking that is invisible in front of audiences and on camera. This version features increased sensitivity for distance miking and captures detail for quieter instruments. Flexible close miking techniques are aided by the bass and cello mount, which sits securely behind the bridge with a positioning arm for placement. In addition, the 5' cable is hardwired to the mic and terminates with a 3.5mm locking connector for direct connection to Sony ZTX-B01 and ZTX-B02RC wireless bodypack transmitters.

Hypercardioid Polar Pattern    For Instruments and Sound Reinforcement    Hardwired Connector    Natural On & Off-Axis Frequency Response    For Uncolored Recordings    Reduced Feedback Issues

The I2 maintains excellent pattern control and frequency response at all angles. It offers uncolored recordings and reduced feedback issues.

Flexible close miking techniques are aided by the instrument mounts, which position securely and gently on the instrument for capturing audio.

Small size and sonic precision makes this microphone suitable for X-Y, M-S, and other techniques that rely on accurate, coincident positioning and consistent patterns.

The hypercardioid polar pattern has a narrower pickup pattern in its front than the cardioid polar pattern. It offers better rejection of ambient noise and the working distance is about twice that of the omni polar pattern. The hypercardioid has a small "pickup lobe" directly behind the microphone and exhibits maximum rejection areas behind and to the sides (about 60 degrees away from the rear of the microphone on either side) of the mic. The hypercardioid pattern works best when the loudest unwanted sounds—like speakers—can be positioned in these nulls.

Q: 7. I got this to go with the sony zv1 camera (shown in sony's own advertising as working). When attaching to the hot shoe I get this error... This accessory is not supported by the device and cannot be used. Is it compatible with the zv1?

A: Yes, the ECM-W2BT is compatible for use with the ZV1 camera. Since the ZV1 has a standard MI shoe (without a digital audio interface) set the switch on the mic to "analog" and make sure the receiver is pushed in all the way on the MI shoe to be certain that it is fully connected. Keep the power for both the camera and the mic off and wait until the receiver is connected before powering them on.
