want to design an audio switching system

[hanif]

Hello,

i got an assignment to replace an old audio channel switching system by a new one . there are 7 audio sources as inputs and they required to be routed to operators so that one operator can listen any one audio at a time. the selection of audio channel is to be made remotely by operator using serial link. moreover there should a touch screen panel also for manual selection of audio.

the old system is consists of PC104 cpu with I/O board and one audio switching matrix card.

i want to design this using National Instruments hardware and Labview but unable to identify the hardware for this. i would be highly obliged if someone guide me to the right hardware.

do you want to use hardware already available or do you want to design a new one ? I'm asking because the hardware available from NI is quite expensive.
