ABSTRACT:
An active dual channel tuning control particularly useful for television and stereo applications has two independently adjustable channels. For example, each channel for stereo has an input for receiving a decoded signal which represents the left or right channel information. Each channel additionally has a feedback amplifier with an adjustably turned output to permit highly selective tuning and impedance matching to the following amplification stages. Switching networks are provided for reversing the channel outputs as well as for selectively inhibiting either of the channel outputs in either the normal or reversed channel condition.
