I just checked the benchmarks manual and it says: " The coaxial inputs use female RCA connectors that are securely mounted directly to the rear panel. The input impedance is 75 Ohms. Maximum word length is 24-bits. All sample rates between 28 and 195 kHz are supported.
The Coax inputs are DC isolated, transformer coupled, current limited, and diode protected. The RCA body is bonded directly to the chassis to prevent currents in the internal ground systems. This direct bonding also maximizes RF shielding. " So, it's weaknesses here imho are 1) RCA instead of BNC and 2) RCA body not isolated. Also, the "Coax inputs are DC isolated" statement is not fully true as ground is not isolated, but the signal is. When you isolate the RCA body from the chassis, it can't see "currents in the internal ground systems" as the result. They have more than one ground system? Also, RF shielding can be done just as well with insulated connector-bodies although it might be a problem with RCA. There are BNC connectors with chassis-insulation built in just for this purpose. But, when you have no ground-loop issue, it doesn't matter, or use toslink. I think the RCA's are too closely grouped to allow replacement with BNC. On another front: I don't see the need for diode protection here... I think it's a misprint because you would rectify the input-signal... cheers, Nick. -- DeVerm ------------------------------------------------------------------------ DeVerm's Profile: http://forums.slimdevices.com/member.php?userid=18104 View this thread: http://forums.slimdevices.com/showthread.php?t=52817 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
