Got a few questions to the ML/MCL Converter On the technical page of Beoworld it says: "It provided a power output of 30W per channel and could drive 4 MCL rooms fitted with passive speakers. " In the specs on same page it says: "Long-term max. output power IEC 2 x 60 watts / 8 ohms"   Q1: what is the power output at what ohm ? Q2: how can it drive 4 mcl rooms ? Q3: is it safe to use with a pair of 4 ohm speakers ?   Thanks R.
