VP88 Stereo Condenser Microphone |
|
|
Product Code: 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.
- 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
- Frequency Response : 40
to 20,000 Hz
- 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).
