Model VP88 User Guide
GENERAL DESCRIPTION
The Shure Model VP88 is a stereo microphone equally effective
in studio broadcasting applications as in the field for electronic
news gathering (ENG).
This stereo microphone combines two condenser cartridges in a
single housing, in a mid-side (M-S) microphone cartridge configu-
ration. One cartridge (Mid) faces forward to capture on-axis sound
in a cardioid pattern. The other cartridge (Side) is bi-directional,
capturing sound from either side.
Containing three settings for different degrees of stereo image
separation, the VP88 contains an internal M-S matrix that can be
bypassed if an external matrix is used, or if stereo imaging is done
in post-production. External switches control output mode, stereo
imaging, low-frequency roll off settings, and battery on/off.
When the VP88 is set for stereo mode operation (H, M, or L), the
left and right signals should remain fully separated and kept at
equal levels to maintain a balanced stereo effect.
MOUNTING
The VP88 can be mounted on a standard microphone floor
stand, fishpole or boom. Make sure the front of the grille faces the
sound source and the top of the microphone faces up, so that the
the resulting stereo image matches the left and right components
of the sound source.

A88SM External Shock Mount
The optional A88SM Shock Mount provides optimum isolation
from stand-transmitted shock and vibration. The A88SM is ideal for
critical studio applications and contains a standard mounting foot
for use with most electronic news gathering (ENG) video cameras.
