Audio Developments AD149
Drama & Location Film Handmade Portable Mixer
The location sound recordist of today demands more facilities and control from a portable mixer. Following years of research the design team that produced some of the most successful portable mixers in the world has created the AD149. It sets a new standard for the twenty-first century by offering a degree of sophistication together with a simplicity of operation never previously encountered in a mixer of its type or size.
Take for granted the functions and qualifies that have made Audio Developments famous world-wide for sound quality and ruggedness.
