ACP54 Digital Audio Control System | 28 V, NVIS Green B Faceplate

Product Description

Canyon’s Digital Audio Control System (DACS) is a flexible solution designed to fit the needs of mid- to large-size helicopters and a range of fixed-wing aircraft, performing a broad range of missions. It is software-configurable to the exact audio distribution, control and warnings needed to meet each aircraft’s unique mission. Removable legends permit operators to quickly and inexpensively adapt radio updates over an aircraft’s lifetime.

DACS is a fully-digital audio processing and control system that provides the most crisp and clear audio quality in our industry. When compared to traditional analog system installations, DACS provides a dramatically simplified installation with reduced wiring and maintenance costs. DACS also provides improved performance with more features, reduced crosstalk, and higher immunity to noise.

This DACS (EDMO# ACP54-001) is compatible with 28-Volt lighting only and has an NVIS Green B faceplate.
