"And you can tell everyone at Parasound that we are super impressed by the 4 DAX as it transforms a commercial setup combined with several Sonos connects and a Parasound ZoneMaster 450, 650 or 1250. The sound is obviously much more clear, dynamic and involving in these challenging environments..."

"It not only addressed the DAC & organization challenges but gave me the capability to send 12v triggers to each amplifier zone..."
"Installation was pain free and straight forward with the 4DAX. The digital audio light helped troubleshoot a bad digital coax cable..."
"...I was truly impressed with how the audio sounded and felt at ease with the discretionary spend around the 4DAX while giving my wife the ease of use of a Sonos deployment."
