What if your amplifier requires a voltage to activate instead of a ground? No problem! Here is what you do: Connect ONE side (either center or shield of RCA jack on RBI-1) to YOUR supplied keying voltage, then use the other side (either center or shield of RCA jack on RBI-1) to send the switched voltage to your amplifier. Remember, the RCA jack on the output of the RBI-1 is then being used as a switch to connect whatever you put on the shield (for example) that gets connected to the center (for example) when you key your radio.See our eBay store listings for our complete line of Amplifier Relay Buffer Interfaces. In other listings we have models with 2 radios and a bypass switch, 2 or more amplifiers or other device (like noise reduction unit keying, mute, etc) When connecting your Radio and Amplifier, there may be switching voltage, polarity, and current incompatibility that can cause damage to your radio or amplifier if connected without a switching interface between them. Even if your internal radio switching looks like it might be usable, it is wise to have an extra degree of isolation between your amplifier and radio with our relay buffer interface. 73, Dan W7RF ( Radiodan ) WE SHIP 5-6 DAYS A WEEK!
