FAQ

Can I still purchase a Companion unit?

Companion units are discontinued and are not produced anymore, and will only be available for sale until the remaining stock lasts. In order to upgrade from stereo to dual-mono, you will simply need to purchase a second unit and get a digital cable separately.
