Toughest Built Electronics In the Industry. 
KDM models have lasted 20 plus years in the field. They are built tough for the installation environment to provide years of service. We use solid metal plates and anodized markings that never wear off. The volume controls use conductive plastic and are sealed from outside elements. They will never oxidize and cause issues with sound quality.

Technology without custom software / programming!
The product never expires. KDM does not use any software or require product specific installation / operational training classes. When you buy KDM products you actually own it, not the installer or manufacturer.

Easy to install.
Provide up to 3 line level balanced signals in and receive 1 balanced signal out. 0 gain. Easy to install using 2 RU tabs (hardware to mount is included). Each input signal has it’s own independent mute circuit for custom options.

Install them anywhere and add on at anytime.
The Octasound RAVC1 can be placed anywhere in a facility and fits into a standard single gang electrical box.
