I wanted to confirm the Mercury current consumption. Russ posted the below in the diyaudio forum, but it wasn't clear to me from the back and forth.

To confirm, total current consumption is 200ma? 100ma for L and 100 ma for R? And if you were to run a dual-mono configuration with separate power supplies for each rail (4 total supplies), current consumption would be 50ma + for L / 50ma - for L and 50ma + for R and 50ma - for R?

I couldn't tell from Russ's comment ("200ma total per rail for both") whether that meant 200ma total or 200ma per rail, so 400ma total.

Thanks.


about 100ma per channel (each has it own supply input)

So combined ~ 200ma - I power mine with a single Placid HD-BP right now.
Just to confirm, 100ma + & 100ma -, correct? AND at +-15V?

Yes - both rails will be very near those values at +/- 15V per channel (so 200ma total per rail for both).

Bump. Brian's post here also confused me, suggesting to plan for 5-600ma per rail.


Depending on the DAC output level, and gain used, it is safe to plan for 500-600mA per rail (+/-) to allow for ample headroom.
