General Description

The VP82 is a professional shotgun microphone for use in sound capture and
reinforcement. Compact and lightweight, with wide aperture and excellent
off-axis rejection, the VP82 is the affordable and reliable choice for camera-
mounted A/V media production applications.
Features
• Premier production microphone crafted with Shure quality, ruggedness,
and reliability
• Highly directional, uniform polar pattern optimized for distant pickup
• Low self-noise and high output level
• Lightweight, compact design accommodates prolonged operation,
minimizing operator fatigue attributed to many shotgun microphones
• Class A, discrete, transformerless preamplifier provides transparent,
extremely fast transient response with no crossover distortion and minimal
harmonic and intermodulation distortion
• Aircraft-grade aluminum alloy construction resists wear and abuse
• Operates over a wide range of temperatures and humidity
Rycote Custom Accessories
Shure offers custom Rycote suspension mounting and wind-protection solu-
®
tions designed for Shure VP shotgun microphones.
Wind-Protection
Use the supplied foam windscreen to reduce wind-noise. For increased pro-
tection, Shure offers two premium Rycote
• Softie Windshield: Attenuates up to 25 dB of wind-noise.
• Suspension Windshield Kit: Attenuates up to 38 dB of wind-noise while
preserving critical high frequencies. Included Lyre suspension mounts
provide up to 25 dB of isolation.
Suspension Mounts
Shure offers four Rycote Softie Lyre Mounts to reduce handling noise and
®
low-frequency vibrations by up to 15 dB:
• InVision Video: Secures directly onto standard camera shoe.
• Camera Clamp Adapter (CCA): Fits into a standard camera clamp.
• Pistol Grip: Adjustable handheld mount.
Note: All Softie Lyre Mounts (except InVision Video) are equipped with 3/8"
and 5/8" female threaded adapters for additional mounting options.
XLR Connector Gasket
This microphone is supplied with a small corrugated rubber ring in the XLR
connector to absorb the mechanical slack between the microphone and
cable. Many high-end cables are made with a rubber shoulder on the XLR-F
for the same purpose. When connecting this microphone to a cable with a
rubber shoulder XLR-F connector, remove the corrugated rubber ring from
the microphone to ensure a proper fit.

Load Impedance
Maximum SPL capability, output clipping level, and dynamic range vary with
the input load impedance of the preamplifier to which the microphone is con-
nected. Shure recommends a minimum input load impedance of 1000 Ohms.
Most modern microphone preamplifiers meet this requirement. Higher imped-
ance results in better performance for these specifications.

Power Requirements

This microphone requires phantom power and performs best with a 48 V DC
supply (IEC-61938), but it can operate with supplies as low as 11 V DC. Most
modern mixers provide phantom power and require the use of a balanced
microphone cable: XLR-to-XLR or XLR-to-TRS.
