I run 6 with no problem. I never have all 6 running and only run a pair in sync mode when entertaining.
How many Logitech Duets on one system
I'm looking at using the Logitech Duet to run my whole house audio. I'm planning on zoning the house and yard with 6-10 separate units allowing each bedroom and seperate zone to control their own area. Will this work or will there be problems? So far I'm running four zones without trouble.
