Cable Solutions Digital Audio Switch

7x1+1 Automatic Electronic Switcher for Coaxial and Optical TOSLink Digital Audio Sources

Cable Solutions Digital Audio Switch

Cable Solutions DAS-001 Automatic 7x2 Digital Audio Switch.  In this photo, the coaxial and TOSLink outputs connectors can be seen, as well as the USB/power connector and the manual input selection override button.

Our DAS-001 Digital Audio Switch offers a unique combination of performance and features.  It's great for applications like expanding the input capabilities of sound bars, A/V receivers, preamplifiers, or just about anywhere that more inputs and automatic switching are needed.

Automatic Input Detection / Switching Logic

All inputs are assigned priorities, with optical 1 having the highest priority, followed by RCA 1, then optical 2, and so on. If a signal is detected  on an input with higher priority, the switch will jump to that input immediately. If there are active signals on multiple inputs, the switch will stay on the current input, as long as there is a valid signal.  If the signal becomes invalid, the switcher will then check the next active input. If the signal there is valid, then that input will be automatically selected.  If the signal there is also invalid, then the switcher will continue to check inputs in sequence.  This latest version also includes a push-button switch for anal override.

A power supply is not included, although the device is USB-powered, so it can be powered by USB bus power, say for example, from a TV, or alternately, just about any USB power brick. It also runs fine on a cell phone charger.  The DAS-001 Digital Audio Switch comes with a standard one year limited warranty from Cable Solutions.
