Modular 4 channel audio system


Actually we are developing a modular 4 channel audio system.

We have 4 analog signals which go into an ADC (like AD1974). From there we want to send the digital data (sample rate 48 kHz) as one multiplexed serial signal to another box with a DSP (ADAU1466). The distance between these two boxes should be between 2 m and 10 m (not finally defined yet). It is important for us to have a serial signal that we can send the data over only one wire.
I was thinking about using the TDM mode of the ADC. Is it possible to send a TDM signal over a few meters? I could not find any information about this but I suspect that the idea is too simple. 
Thanks for your support in advance.
Best regards
