Speakers

The TVA50 will remain stable when driving a 4 ohm load. If only one pair of speakers is being driven, 4, 6 or 8 ohm speakers systems can be used. If switching two pairs, 8 ohm speakers must be used.

Fixed/Variable Line Level Outputs

To control the TV volume through the speakers, the variable output on the TV must be connected to the TVA50 Line IN.

Using Volume Controls

Depending on your installation in-wall volume controls may be used to control the speaker level. Connect the in-wall volume control to the TVA50 speaker output. This requires use of the fixed output on the TV. In this application, volume for all sources is controlled with the in-wall volume control.
