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 operate, easy to install.
No operating manual is required. Simply turn the volume up and down and adjust the source volume! Zone control, TV’s, Projectors wireless microphones and more can have a mounted volume control in a convenient location.
Zone control is ideal where distributed audio (70V) power requirements exceed industry 70V Volume control power specifications. Installation requires a screwdriver and wire strippers.

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. It’s unique daisy chain ability allows the RAMX2™ and the RABX2™ to be wired together with a single CAT5 wire.

Hearing assist Ready
An additional constant level output provides a means to supply the RAVC1 audio to a separate Zone or Hearing assist system. When the RAVC1™ volume is adjusted it will not adjust the other zone / hearing assist system.
