CA10CD: Amplifier Specifications
The CA10CD is a 6 wire product; it includes the prong plug (2 stereo jacks) which plug directly into a 6-wire console. This is different from the CA10 which has a 4 pin modular plug which plugs into a standard telephone hand receiver port. Because the CA10CD is considered a cordless amplifier, and most consoles have the amplification built in, you should not require an in-line amplifier. If you require more receive volume than what the headset is capable of giving, the volume within the internal console would have to be adjusted by the console technician.
