Couple of questions about XMC-1

[sharok]

Hello Everybody,

are the XLR outputs (7.1) on XMC-1 true balance? My Anthem P5 amplifier has a 6db attenuator button. Should I use those buttons (to attenuate the signal) when I connect XLRs from XMC-1 to my P5 or I don't need to use those?

If I use audio USB (USB DAC) as the audio input, do I have to have assign a video input also or is it optional?

How about video out when using USB DAC? Do I have to assign a video output while using the USB DAC or is it optional?

Thanks

OK - it's CLARIFYING time.


ALL of the balanced outputs and inputs on ALL of our equipment that has them are REAL BALANCED CONNECTIONS.
(In a balanced connection, the two signal leads carry equal but out of phase signals, which allow any noise picked up by the cable to be cancelled out.)
All of our outputs are real balanced outputs, with active signals on both lines, and all of our balanced inputs difference the two signals to cancel noise.

The LF and RF outputs on the XMC-1 are generated by fully differential balanced DACs, and follow a balanced signal path ON THE WAY TO their balanced outputs.
While the other channels are generated by high quality DACs operating in single-ended mode.
And the fully differential balanced front channels have slightly better audio performance overall......
But all the balanced OUTPUTS on both are fully balanced, and will give you all the benefits of a BALANCED CONNECTION.

(And, to be honest, with a SUBWOOFER output, where the frequency response is quite limited, but you might be running a long cable, the balanced CONNECTION is the important part.

I have just a quick question about the XLR port on the MC-700 (And btw I'm planning to buy it regardless of the answer)

Is it fully balanced? IE like the L/R on the XMC-1 or faux balanced like C/SR/SL/BR/BL/LFE on the XMC-1?

My current plan is to order the A-700 first and later get the MC-700 since my current amp is only 2ch so I'm not even able to fully use my current pro/pre.


Thanks and have a nice day.

Many thanks for clarification.

I got half of my questions answered.

For any input that does not have a video signal (like the usb or balanced analog in, etc.), you do have have to and in fact can't assign a video input. However, if you want to play video while listen to such an input, the xmc will pass the last video signal that was being used prior to switching inputs. So, if you were watching a bluray via the xmc and leave the bluray player running while switching to the audio only input, you will see the video from the bluray as you listen to the usb input.
