VP88 Stereo Condenser Microphone

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

Single-point, stereo condenser microphone for use in professional studio recording, field production, electronic news gathering, and studio broadcasting.

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

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).
