Buffalo II

On the Legato manual there are the current requirements, but these are for the Legato 1.

How much current should I give to the legato 2.0 ?
Does it change anything the fact that I am running double current ?
What's the contribution of the balliste ?

Additionally it looks my buffalo drain only 65 mA. Am I doing something wrong ? The manual says 290mA.

Thanks,

Hi,

Are you measuring the correct current? - If you are using the Placid for the Buffalo supply, 65mA looks like the shunt current. If you are using the Pladid check that you are measuring the voltage drop across the correct resistor. I have Tridents installed so I can't comment directly on the standard install but 290mA would seem about right given that after adding the Trident shunts the draw is around 500mA.

The HiFace puts out almost 5V and can be connected to D1 and ground instead of SPdIF and ground. Turn off the SPDIF switch if using this connection.

Anyone know what the output of the EVO is?

If I remember the Evo have 0,5V at output

I just put a 0.5 ohm resistor and measured the drop. I have a linear regulator now.

Sorry, I did mistake. Actually I have connected DCK & GND to S\PDIF
output from Hiface. SPDIF switch is on. When S\PDIF from Hiface is
connected to D1 & GND and SPDIF switch is off (or on), there is not sound.
I will do more tests. Sorry for wrong information.

Did you have the AVCC module installed?

[Nikon1975]

I guess I messed up something while measuring. The real reading is 240mA for each Buffalo and 200 mA for the legato with the balliste installed.

Does it make more sense ?

Yep that sounds about right.

Out of curiosity: what is the rationale behind, and benefit of, two Buffalo's for one Legato?
I thought that the current swing of the Buffalo was rather high and might actually have considered the opposite configuration (two Legatos for one Buffalo).
