Shure VP88 User Manual

GENERAL DESCRIPTION
The Shure Model VP88 is a single-point, stereo condens-
er microphone for use in professional studio recording, field
production, electronic news gathering (ENG), and studio
broadcasting applications. It combines two condenser car-
tridges 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 pro-
duction environments.
The VP88 uses a mid-side (M-S) configuration. One mi-
crophone cartridge (Mid) faces forward to capture on-axis
sound using a cardioid pickup pattern. The other micro-
phone 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 exter-
nal matrix is used or if stereo imaging is done in post-pro-
duction. Switches on the top of the microphone control out-
put mode, stereo imaging, low-frequency rolloff settings,
and battery on/off.
The VP88 can operate on phantom power or an internal
6V battery. The VP88 is supplied with a multi-connector "Y-
splitter" cable, foam windscreen, swivel stand adapter,
6-volt battery, and zippered carrying/storage bag. Optional
accessories include an isolation mount, a 7.6 m (25 ft) mi-
crophone extension cable, a phantom power supply, and a
4.3 m (14 ft) microphone stand.

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 Shockmount
The optional A88SM Shock Mount provides optimum iso-
lation from stand-transmitted shock and vibration. The
A88SM is ideal for critical studio applications contains a
standard mounting foot for use with most electronic news
gathering (ENG) video cameras.
POWER
Phantom Power
The VP88 can be phantom powered by any microphone
mixer or console providing 9 to 52 Vdc phantom power, or
by a phantom power supply such as the Shure PS1A. Each
balanced audio cable pair (pins 2 and 3: Mid/Left; pins 4 and
5: Side/Right) carries the supply current to the microphone,
and the cable shield (pin 1) is the ground return.
The Mid or Side output can be used individually with ei-
ther phantom or battery power. When operating in the Ste-
reo mode without battery, both Mid/Left and Side/Right out-
puts must be phantom powered.
