Audio-Technica AT875R — Compact Shotgun Microphone for Video and Broadcast

The Audio-Technica AT875R is a compact shotgun microphone tailored for video production and broadcast (ENG/EFP) audio. At 175 mm long and weighing just 80 g, it mounts easily on a DV camcorder or compact digital camera and keeps your setup agile. The line + gradient configuration yields a narrow acceptance angle for capturing distant sound and excels at rejecting off-axis noise.

What Stands Out in This Microphone

Featuring a fixed-charge back plate and a permanently polarized condenser element, this mic achieves excellent on-axis directionality with its line + gradient polar pattern. A tailored frequency response, along with a gentle high-frequency boost, brings clarity to spoken word. Using only phantom power and lacking on-mic controls, it delivers a no-fuss workflow.

Frequency Response and Sensitivity

This model is optimized for voice, rolling off low-end rumble but retaining vocal detail.

• Frequency Response: 90 Hz – 20 kHz — helps reduce traffic rumble and wind noise
• Less preamp gain is needed due to high output from the Open Circuit Sensitivity: –30 dB (31.6 mV) re 1V at 1 Pa.
• Signal-to-Noise Ratio: 74 dB (1 kHz at 1 Pa) — delivers clean capture for quiet interviews

Power Requirements and Build

With wide phantom-power compatibility, the AT875R integrates smoothly with handheld recorders, field recorders, or built-in camera preamps.

• Phantom Power Requirements: 11–52 V DC, 2 mA typical — works with virtually any camera or recorder
• Maximum SPL: 127 dB SPL (1 kHz at 1% THD) — handles loud sources without distortion
• The Dynamic Range: 107 dB (1 kHz at Max SPL) ensures you can record everything from hushed dialogue to loud sound effects without loss of detail.

Physical Specs and Connectivity

Compact dimensions and a standard XLR output mean this microphone fits seamlessly into professional video workflows.

• Length: 175 mm — conveniently fits on camera or in confined indoor spaces
• Diameter: 21 mm — compatible with standard shotgun windscreens
• Weighing just 80 g, it won’t burden a boompole or tip a camera rig.
• Output Connector: Integral 3-pin XLRM-type — balanced output for long cable runs
