We know you're dealing with limited space so this intercom is the smallest 4-place, voice activated panel mount on the intercom market. The whole thing fits in the palm of your hand.
You get 3-position transmit, auxiliary input, selectable auto muting, pilot isolate, plus high sound clarity and easy volume adjustment. Includes a built-in failsafe mode.
Simple to use and sized to fit anywhere in the panel - vertical or horizontal mounting. Selectable auto mute can be configured so radio mutes intercom conversation, music, or both. Your choice.
