DM58 Preamplified Digital Microphone
Features

Compliant with ED-112A specifications

Both the L3 DM58’s Cockpit Area Microphone (CAM) and preamplifier are ED-112A compliant, providing versatility when used with either current CVRs or digital next-generation voice recorders. The ED-112A CAM includes Micro-Electro-Mechanical Systems (MEMS) technology, improved vibration immunity for helicopter and turboprop installations, and improved cell phone/GSM signal immunity. The ED-112 Preamplifier features both analog and digital output options and features Digital Signal Processing for precise performance.

Versatile mounting options and formats

The DM58’s mounting capability is compatible with legacy CAM models. Additionally, the ED-112 Preamplifier features both analog and digital output options and features Digital Signal Processing for precise performance. The integrated microphone and preamplifier also supports modern glass cockpits where a traditional CVR control unit/preamplifier is not desired. TSO approval simplifies certification for aircraft manufacturers, installers and end users.
