Connection between Monic and Mojo

[cw]

Hai fish

how long could be the connection between Monica and Mojo. I would like to put both in two separate housings. The power supply in the third housing.

hi carsten

monica only has cs8412 driving the output so it doesn't have much drive. better put it as close as possible.
monica2 has the reclocker chip driving the output. this could drive a bit of current.

monica3 or usb monica only has the receiver dir9001 driving the output. again, not enough. better put it as close as possible.

hope this helps.

Hi yeo,

thanks for your reply and your explanation. Ok, then i put both in one housing and close to each other.

Sorry, message temporarily deleted for further investigations...

hi martin

you are right. usb-eiaj and black crow have the same problem, which is my mistake. i made a mistake in the i2s-eiaj circuitry, thus the channels are reversed.

sorry about that.

Hey Yeo,

wow, this was one FAST reply!

I deleted my message because I realized that the balance setting of the winamp player is of course BEFORE the analouge part, therefore I wanted to take some more time to confirm my findings.

But since you confirmed this by yourself, let me summarize the facts:

1. Reagardless of wiring after the analouge part, any software media player would show a reversed balance because the error is in the dac part, not the analouge part, right?

2. Also regardless of this, one has to swap output channels on mojo, so "R" is actually "L", and "L" is "R", right?

For reference, here is my previous post:

"Hi Yeo!

Regarding Mojo (not Mojo 2), I discovered a strange thing today. A few days ago I listened via a notebook soundcard to a certain track from Björk's album "Homogenic", where a drum part at the beginning of the track is only recorded on one channel. With the soundcard it was on the right channel.
Then I switched back to Monica USB & Mojo, and there the drums where on the left channel! (Or the other way round, can't recall exactly, but interchanged nevertheless.)
I checked my wiring twice, and then I enabled the volume and balance control on the winamp player, and with balance set to the right channel I hear the left speaker and vice versa. As said, no errors in soldering or wireing (Monica-Mojo still sits "naked" on a peace of wood, so I could check everything easily).

I checked with two different amplifiers, same result!

Could it be that the prints on the analouge otput marked "R/G/G/L" are labled the wrong way??

I mean, for the USB-section there might be no possibility of reversed channels, I guess.

Thank you!
Martin"

hi martin

yes, regardless of analog wiring, because the error is in the digital domain.

for spdif monica, the labeling on mojo is correct. for usb monica and i2s monica, got to swap L and R.

OMG!

I've been listening to my newly purchased Monica USB & Mojo for almost 2 weeks now, and all the time with reversed channels!

No wonder I wasn't completely satisfied with the result....

Now I swapped left and right on the interconnects and everything works properly. Even the balance control in Winamp now shows correct results.

I just checked with my girlfriends Enhanced USB Monica module and there is no such problem.

Yeo, I can only hope that all the other buyers of the affected modules know about that, as I didn't!

That is interesting    I have never cared one hoot about which channel is left or right. My left ear and right ear never complained to me which channel they get to hear either  What happens when one is facing away from the speakers, the channels get crossed over again...oh well. Am I the only one who doesn't care? The only downside is if one speaker stopped making music, I would have no idea which amp channel had failed

hi martin

the enhanced usb monica module uses the same i2s-eiaj circuitry. i'm sure the channel is swapped unless your amp's channel is swapped as well.

hi ian

yeah, same here. i don't care much whether it's L or R but i acknowledge that some listeners may not feel this way.

lol me too

i know my channels are swapped and i dun even bother to swap back. but since its mentioned here. i might try to swap to the right one
