The IA-1250 is a twelve channel audio distribution amp that can be configured for up to six stereo 4Ω/8Ω zones; six stereo 70/100V zones or three high powered bridged zones…in any combination of stereo 4Ω/8Ω, 8Ω bridged and 70/100V zones at the same time! That’s pretty good in itself…but there’s a whole lot more…
Each zone can be controlled via IR or RS232 for ON/OFF, source select, volume/mute, treble/bass and left/right balance. The IA-1250 can be configured to automatically send RS232 zone status updates or respond to queries to confirm zone status and settings. Commands for volume, treble/bass and balance can be specific values or step commands depending upon the control application.
Note: before start operating check and set the AC voltage selector in the right position
