Hi, it's always possible to set MASTER / SLAVE.

Have you read and followed page 28 'Choosing standard settings' of the DSP User Guide ?

What model of DSP5200 are these (Legacy, SpeakerLink, SE)?

What firmware version are they running (press display when in standby)?

What TYPE number did you set them to?

Which input on your Master speaker are you using?

Note the slave speaker should use / be configured for input D1 / SpeakerLink), even if you're using D2 on the Master.

Regards,
Carl
