Shure VP88

The Shure Model VP88 is a single-point, stereo condenser microphone for use in professional studio recording, field production, electronic news gathering (ENG), and studio broadcasting applications. It combines two condenser cartridges in a single housing to create a stereo audio image of the sound source.

It is unique in its ability to capture the realism of a live event and yet withstand rigorous field production environments.

The VP88 uses a mid-side (M-S) configuration. One microphone cartridge (Mid) faces forward to capture on-axis sound using a cardioid pickup pattern. The other microphone cartridge (Side) is bi-directional, capturing sound from either side.

The VP88 contains an internal M-S matrix with three settings for different degrees of stereo image seperation. The internal matrix can be bypassed if an external matrix is used or if stereo imaging is done in post-production. Switches on the top of the microphone control output mode, stereo imaging, low-frequency rolloff settings, and battery on/off.

The VP88 can operate on phantom power or an internal 6 V battery. The VP88 is supplied with a multi-connector “Y-splitter” cable.
