7x2 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

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 not valid, then the switcher will continue to check inputs in sequence.

Please be aware that what we are offering here is a fully-functional prototype, and as such, there is no branding or labeling,  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. For example, it runs fine on a cell phone charger.  The DAS-001 Digital Audio Switch is a prototype, but we are confident in the design, so it comes with a standard one year limited warranty from Cable Solutions..
