Are you guys connecting the XLR d-tabs to star ground? Or are you leaving that open on the connectors? I have seen pictures and replies about people doing it both ways. What yields better results?

Also, whatsup with there being two holes for Mains Safety Earth? I connected only one to star ground. I don't know what to do with the other one. I saw some pics where it looks like there was a screw in the 2nd one, but I can't tell what's going on there...

Sorry I'm new to this. Help?

Hi Paul, thank you so much for your advice. That is what I was actually trying to remember to search for, couldn't remember the title of it and had seen some folks suggest reading it on here... Very helpful thank you kindly.

One more question: Are you guys terminating the output at 600ohms or are you leaving it at stock? What's the difference in the sound? I'm plugging it into an interface, UA Apollo to be specific. Should I be terminating to 600 or leaving SW1 open?

The instructions say solder those pads together, so I just do that. You can experiment and let us know what you think.

Thanks!

Thanks Paul. I wish there was some more info than that for those of us less experienced, but thanks for your input!

Best,

Phew! I just finished casing up two of these units. I am very proud of the way they turned out. Cases from Dan at Collective Cases and the knobs I bought from CAPI-Gear.

EDIT: Scratch that! I don't know what was wrong when I tried it yesterday, must've been plugging something in wrong. The line gain is working perfectly on both units.

Everything works! I am incredibly stoked. Beautiful sounding units. I love running a 2-mix through them on the stereo bus! I used these to record a live piano concert last night. They sounded incredible.

Thanks AML!

I want to share some recordings I made of my sax through one of these puppies. I love the sound of these preamps! So warm and lovely.

First, flat EQ with no extra input drive: https://soundcloud.com/mattmarantz/ez1073-tryout-flat-eq

Some brighter EQ added from the ez1073: https://soundcloud.com/mattmarantz/zz1073-tryout-brighter-eq

Lastly, no EQ added, but some input transformer drive was used and the trim was backed off a bit: https://soundcloud.com/mattmarantz/ez1073-tryout-little-bit-of-input-drive

So cool that you can get so many sounds out of this box. This is the 1U rackmount version for anyone interested. Love it!

I just finished a pair of ez1073s,

One is working good, but there is a level drop when i flip the phase switch...?

The second one I have a very low output from the mic channel, and a lot of buzzing when i touch the mic gain knob... 

I have already gone over looking for bad joints and trying to clean up but no luck so far.

Any tips are appreciated!   

Did you manage the solve the issue with the second unit?

[EarthTone]

Yes! Found a bad solder joint. Everything's finished & working awesomely now. Thanks,

Matt
