DESCRIPTION
The TEA6430switches 5 stereoinputson 4 stereo
outputs, providing the customer with high quality
sound (low noise, low distortion). The 4 stereo
outputs can be set separately in high impedance
state, to enable parallel connection of several devices(up to4). All functionsare controlledthrough
