My understanding (and I'm not doing this, it is simply my understanding) is that SL is not AES/EBU but the difference is more about the application of the standard than a significant difference and there's been several folks advocating wiring plans to convert SL to AES/EBU and I've not seen anyone come back and say it doesn't work. The DSP5200s do have clipping warning lights if you do end up feeding them too high a signal.

If you're concerned about it speak to Robert who makes and sells the reviver, that's certainly the cheapest off the shelf option and clearly works well (I have 3 of them). OR look out for an AC12. But those solutions do SPDIF to SL not AES/EBU.
