SUS Geophone Contact Microphone | 28Hz High-Sensitivity Version 14Hz Classic Version

Geophone Contact Microphone | 28Hz High-Sensitivity Version vs 14Hz Classic Version

To meet the different needs of field recordists and sound designers, we now offer two tuned versions of our Geophone Contact Microphone.

[1] 28Hz High-Sensitivity Version

A redesigned geophone that breaks beyond the frequency limitations of conventional models. By raising the resonance frequency to 28Hz, the effective frequency response extends up to 3500Hz while achieving approximately 2.2× higher sensitivity than a standard 14Hz geophone.

Sound Character

• Significantly more mid and high-frequency detail compared to traditional 14Hz models.
• Less high-frequency roll-off.
• Delivers strong recording levels without requiring excessive gain.

Recommended For

• Capturing material textures and surface details.
• Recording subtle vibrations and delicate resonances.
• Sound design and post-production requiring a wider frequency spectrum.

[2] 14Hz Classic Version

The traditional industry-standard geophone specification, familiar to many field recordists and researchers.

Specifications

• Sensitivity: 80V/m/s
• Frequency Response: 10–1200Hz
• Impedance: 3500Ω

Recommended For

• Pure low-frequency and subsonic recording.
• Seismic and earthquake-like sound effects.
• Heavy machinery, industrial rumble, and deep structural vibrations.

Shared Features

• Omnidirectional sensing element
• Mogami professional audio cable
• Rugged enclosure designed for demanding outdoor use
