See our 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 yourRadio and Amplifier, there may be switching voltage, polarity, and current incompatibility that can cause damage to your radio or amplifier if connected without a switchinginterface between them. Even if your internal radio switching looks like itmight be usable, it iswise to have an extra degree of isolation between your amplifier and radio with our relay buffer interface.
