VP88 Stereo Condenser Microphone |
|
|
Product Code: VP88
Stereo Condenser |
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.
- VP88 - Includes
"Y-splitter" cable, foam windscreen, stand adapter, 6V
battery and zippered storage bag. Phantom power or included
battery required

Features |
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.
- Time-coherent, Mid-Side (M-S) design for
optimal stereo imaging
- Built-in stereo matrix for direct control
of the stereo spread; direct M-S outputs available
- Mono compatibility ideal for broadcast
applications
- 40 to 20,000 Hz frequency response
- Low noise and distortion
- Wide dynamic range
- Switch-selectable, low-frequency rolloff
(12 dB/octave below 80 Hz) for reduced pickup of ambient noise & stand
vibration
- Operates on phantom power or a 6V camera
battery
- LED power indicator
- Internal shock mount for reduced stand
vibration and handling noise
- Built-in "pop" screen
- Includes windscreen, swivel adapter, and
Y-cable

Specifications |
- Type : Single-point stereo (MS
configuration) condenser
- Polar Pattern
Mid Cartridge: Cardioid (unidirectional)
Side Cartridge: Bidirectional
- Output Impedance : Rated at 150 (100
ohms actual). Recommended minimum load impedance: 800 ohms (may be used
with loads as low as 150 ohms with reduced clipping level)
- Sensitivity (1 kHz, MS mode) : Open
Circuit Voltage: -66 dB (0.5 mV) Mid. (Side level 1.6 dB higher than Mid
level) (0 dB=1 V/Pa)
- Side Level (Stereo mode; relative to
Mid level) : Low: -6.0 dB; Medium: -1.9 dB; High: +1.6 dB
- Clipping Level (1 kHz)
800 ohm Load (less than 1% THD)
-12 dBV (0.25 V)(Mid output, 1% THD)
-10 dBV (0.30 V)(Side output, 1% THD)
150 ohm Load (less than 3% THD)
-25 dBV (0.06 V)(Mid output)
-19 dBV (0.11 V)(Side output)
- Maximum SPL
800 ohm Load: 129 dB
150 ohm Load: 119 dB
- Hum Pickup : -4 dB equivalent SPL in
1 millioersted field (60 Hz)
- Self Noise (Mid, Side, Left and Right
outputs; equivalent sound pressure levels)
24 dB typical, A-weighted
28 dB typical, weighted per DIN 45405
- Dynamic Range : 105 dB (maximum SPL
to A-weighted noise level)
- Signal-to-Noise Ratio*
70 dB (IEC 651) at 94 dB SPL
*S/N ratio: difference between microphone output at 94 dB SPL and
microphone self-noise A-weighted.
- Overvoltage Protection : Maximum
External Voltage applied to Pins 2 through 5 with respect to Pin 1: +/-
75 Vdc
- Polarity
Positive pressure applied from any direction to the Mid cartridge or
from the left to the Side cartridge in the MS mode, or applied from the
front in the Stereo mode produces positive voltage on pin 2 relative to
pin 3 (Mid/Left) and pin 4 relative to pin 5 (Side/Right).
