Help needed with my pre md7's Condenser Microphones

Help needed with my pre md7's

Hey guys, need some help.. So I got a brand new radial workhorse with summing mixer 2 avedis md7 on slot 1 and 2 going into my burl b2 bomber adc.. All brand new all mogami gold cables... So on the md7's I got the line disengaged and phantom turned on... My input is xlr in and output xlr out into burl adc and via AES Into my ULN8...
So for me to get -12 db gain to show up in the burl and my daw I have to turn my trim pot all the way to the end and my gain pod turned to +56 db on some mics on others I need +52 and well my noise floor goes up of course..

Am I doing something wrong? Or this is an acceptable amount of gain that needs to be set for this kinda loudness?
Tested different mics different cables....
Please chime in..

All of my condenser and Ribon mics are Michael Joly mics..

Thanks in advance

Paul

I'm wondering if any of you are using different 500 chassis with louder results on md7's

The Trim (Red Knob) Should be all the way up and the grey knob should bring up level. The line button is not pressed correct?

Something isn't right and I am thinking something isn't right with the work horse.

Yup... My sentiment exactly.. Di's work great with keys and guitars.. So are the trs inputs... It's the xlr's with mics that are dang too low... What box are you using ur md7's in?

And Fredenstien. So when you go in the xlr input are you going out of the xlr out directly below it on the back of the work horse? Are the "feed" switches turned off? If not make sure your grey knob on the md7 is all the way down just in case you get a loud boost when switched the feed

oh brother.. I have two of md7's yes the line is disengaged and yes I'm going xlr in and xlr out they're right next to each other.. Feed and link is off, clicked it on and off just in case.. Also tried different slots in the radial same results

Ok I think I got it under control.. First off. I had my trs cables installed while I had the xlr input in as well.. Not sure if this was the case but as soon as I took out the trs cables I was able to drive my condensers up to 0 with the trim pod all the way up and gain set to +40
That sounds a lot better than 56!

Then for a good measure I installed my obsidian that showed up today and couldn't stop smiling .
My Shure sm58 still needs to be driven up to 52 to get to 0 does that sound about right?

What's really odd is my Michael Joly MJ LR-44 (ribbon mic) needs to be driven to 60 to get to 0.. Is 20 db difference normal or should I have a chat with mr jolly?

Thx for ur help nu-tra

Oookay so the problem is now rectified, here's the piece of information that I acquired during my search.. So radial workhorse with summing mixer has this built in pad... Because it had triple input if you have more input than one plugged in, your output will be padded.. Just like I had my trs cable accidentally plugged in and after removal of it from the jack my md7's got quite a bit louder but not loud enough (too much gain needed) what I completely didn't think of is that I had a dsub to summing mixer plugged in as well and that is considered as an input as well, after talking to radial they told me that you need to treat summing mixer and 500 series like two completely separate boxes... Unless you have lets say 8 radial preamps installed they automatically get multed onto the summing mixer where you can adjust volume and pan and have a output dsub back into ur I/O, other then that u can not have anything on the dsub input summing or otherwise (radial has two dsub inputs) if you want to have an xlr cable jacked into your preamp... Now that everything is unplugged besides the input cable my gain needs to be driven 32-36db for condencer mic 48-52 for carotid and Ribon mics... Depending on the mic it's a bit louder a lot quieter but this is the new norm.. Also loaned a Rupert neve designes r6 rack and my md7's have exactly the same gain specs as on radial (love RND rack it has a power button and tells u how much juice ur modules use) and triple connection as well!

Am I now in the norm?
