Compact audio relay selector for switching audio input and output. Selling due to warehouse reorganization. Removed and stored about a year ago due to a system change, but since I have no plans to use it in the future, I am selling it. It was working normally when removed, but I don't have an environment to test it now, so it is being sold as junk. I'm offering it at a low price, so please understand that it's non-returnable, non-refundable, and non-cancellable (3N).(^^;; - Model Name: Audio Relay Selector - Connection Terminals: Audio Input/Output Terminals - Power Terminals: Ground/Remote/Accessory - Relays: Equipped with 2 relays - Color: Blue - Size: Compact Design Thank you for viewing.
