Eurodesk Input Impedance

[Ed Guidory]

Anyone know what the input impedance is of the Eurodesk 3282a?
I need this information to made a modified cable to properly load my microphone: http://www.recordingmag.com/resource...etail/330.html

Hi Ed,

Please clarify, do you mean a MX3282A? Or a SX3282?

Hmm, I'm going to have to look into that. Not sure which we have, the unit belongs to our drummer. Are the preamps different?

Hi Ed,

The MX series are from ten years ago, while the SX3282 is still in our lineup. The preamps on the SX3282 are a much newer design.

You can see the specs for the MX3282A at:

The specs for the SX3282:

I hope that this is helpful.

Thanks for your help! It is the MX series. However, the PDF you linked to doesn't say the input impedance of the channels. It does say that it uses 4580 opamps, and even looking up the datasheet for that offered no guidance.

Just found out it is the MX series. Nothing in the PDF indicated the input impedance, however.

Hi Ed,

We do not have any additional specs for that mixer. I can try to find out for you, but because of the age of that mixer, i'm not sure if we have that information.

One thing to know is that it is normal to have to turn the GAIN or TRIM up nearly all of the way to get the gain that you need. The gain or trim pots are very non-linear.

Best,
