*CVA50MX-1: When a signal is applied to input 1, inputs 2-4 will be ducked as per the setting of the "duck" control. The level for each input channel is set with the corresponding control. The master volume control and remote volume set the level of all inputs including input 1.

*CVA50PMX-1: When a signal is applied to input 1, inputs 2-4 will be ducked as per the setting of the "duck" control. The level for each input channel is set with the corresponding control. The master volume control and remote volume set the level of inputs 2-4. The input 1 level control is independent and not affected by the master or remote controls.
