Dynaco SCA-80Q


The Dynaco SCA-80Q is an all silicon solid state stereo control amplifier of exceptionally high quality.

It functions as the control centre for all mono or stereo signal sources, such as a record player, radio tuner, tape recorder, television sound, etc., and provides output connections from two 30 watt power amplifiers for either two or four loudspeakers, as well as a front panel jack for stereo head phones.

Thoughtful planning has provided exceptional flexibility with remarkable ease of operation.

The SCA-80Q incorporates special circuitry which enables Dynaquad 4-dimensional playback for increased realism from a four speaker system without any additional electronics.

Alternatively it may be used as a conventional two channel stereo amplifier with provision for optional connection of a second pair of speakers in a remote location.
