Superlux ORTF Stereo Recording Condenser Microphone S502

Superlux ORTF Stereo Recording Condenser Microphone S502

The Superlux S502 ORTF Stereo Recording Condenser Microphone is a professional stereo microphone designed to capture natural, detailed and spacious audio for studio, live and location recording. It uses a fixed ORTF stereo capsule arrangement with two cardioid capsules positioned at a 110° angle and 17 cm apart to create a realistic stereo image with depth and width. This makes the S502 an excellent choice for classical music, acoustic instruments, ensembles, concerts, ambience and other applications where accurate stereo imaging is important.

Natural Stereo Recording

The ORTF configuration is designed to reproduce a wide and balanced stereo field that closely reflects the spatial characteristics of the original sound source. The two cardioid capsules provide directional pickup while the carefully positioned arrangement helps create natural separation between the left and right channels. This makes the microphone particularly useful for capturing live performances, orchestras, choirs, room ambience and acoustic instruments.

The 1/2-inch gold-evaporated diaphragms are designed to provide detailed and natural audio reproduction with good sensitivity. With a sensitivity of -36 dBV/Pa (15.8 mV), the microphone can capture subtle musical details while maintaining clarity across a wide range of recording situations.

Wide Dynamic Range and High SPL Handling

The Superlux S502 offers a 117 dB dynamic range and can handle sound pressure levels of up to 135 dB SPL. This allows it to capture both delicate passages and louder performances with useful headroom. Its 76 dB signal-to-noise ratio and low 18 dB equivalent output noise contribute to clean recordings, particularly when capturing detailed acoustic performances and quieter sources.

Professional Phantom Power and Balanced Output

The microphone operates on 48V DC phantom power with a power consumption of approximately 4.5 mA. Its 200 Ω output impedance and minimum recommended load impedance of 1,000 Ω make it suitable for compatible professional mixers, microphone preamps, audio interfaces and recorders. The balanced output helps minimise unwanted interference and supports reliable signal transmission in professional recording environments.

Durable Design for Studio and Location Use

Featuring a sturdy metal body with a professional black finish, the S502 is designed for regular studio and location recording. Its fixed stereo configuration provides a convenient solution for users who want consistent ORTF positioning without manually matching and positioning two separate microphones.

Ideal Applications

The Superlux S502 stereo microphone is suitable for classical music recording, orchestras, acoustic instruments, live performances, location recording, studio sessions, ensembles, room ambience and drum recording. Its combination of ORTF stereo imaging, high SPL capability and wide dynamic range makes it versatile for both professional and enthusiast recording setups.
