DACT

Wiring examples of how to build active and passive multi-channel  linear preamplifier using DACT components like the CT101 line stage module, CT2 stepped audio attenuators and our Dual Connect solid gold signal wires. The application note covers both 6-channel and 8-channel passive and active preamplifiers for Home Theater and A/V Audio. The designs feature master volume control and volume controls for individual channel adjustment.
