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
- See
also VP64A/VP64AL microphones

| 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).
