Patch Bay

Postby Hyderboy » Wed Oct 02, 2013 1:43 pm

I am looking at the Mixbay with interest, and working out a wiring diagram. I am torn between running my live room snake into my mic pre's first, then outs to bay normal'd to my converters inputs. OR, mic lines to mixbay first. Being able to change pre's from my controll room would be nice, but, shorter chain the other way, and I usually know what pre I'm going to use so?

Torn

Thanks

Having the most flexibility in your studio is always key. Even if you "think" you are going to be using X mic-pre 99% of the time, you might want to experiment with other down the road, or plug in some other way. This Mixbay offers you complete flexibility and even though it would be a little longer cable run, it's worth it over the long term.

Yea, I agree. So, bringing the mic. lines up on the mixbay, would you normal the mic outs to pre ins, or have the pre's setup with out's over in's, just like typical outboard.

I have my mic lines on the top row (outputs) normalled to my mic-pre inputs. Then I have my preamp outputs normalled to my A/D/A inputs.

I am a big fan of having my entire Mixbay fully normalled. This way I can setup the routing schemes I use most and alleviate the use of patch cables, but still retain the ultimate flexibility to route anything to anywhere at anytime.

That being said, if you want to do any multing you'll need to setup those points to be half-normalled.

The great thing about the Mixbay is that you can change both the normal and ground configurations per port pair (that means 96 different configurations are possible as there are 192 points on the bay). You also don't need to unplug any gear in order to change these switches. So, you can start off one way and try something else the next without any hassle.

What about phantom power issues using ribbons. What grounding for the mic lines?

Ribbon mics are fine on the Mixbay. You want the pair fully normalled with the grounds vertically bussed. All port pairs on the Mixbay are independent points that will never stripe across the bay, but setting up your mic lines in this manner ensures that you have an extra level of protection.

I encourage you to visit the product page where there is an Excel spreadsheet for laying everything out, and a very detailed PDF manual available that addresses these types of concerns.

Cool, that's the unit for me. Now, what about outboard (comps, eq's ), what is the best configuration for normal's and grounds?

The standard grounds bussed configuration (as the Mixbay ships) should be fine for most all applications other the mic lines. As I mentioned earlier, I like to set everything up to be fully normalled so I can insert a TT cable on the front and break the normal whenever I need, however if you want to mult (duplicate signals) you will need to set that port pair to half-normal. The Mixbay comes set to half-normal/grounds bussed across all port pairs. Modifying each port pair is as simple as sliding a switch on the rear of the bay.

Okay, so I have always had my mic lines ( live room snake) go streight into me pre ins( XLR). I am good with a solder iron, I make a lot of my own cables and diy projects, but I have not wired up DB25 connector before.

My main snake is 16 channels, so I would like to remove the XLR's and wire DB25 for connection to Mixbay. Can you recommend a DB25 connector that is good for custom work?

Then I'll be ready to roll.
Thanks

Any good quality DB25 connector should work just fine. Remember that all of the Mixbay DSUBs are in Tascam wiring format so make sure your pin configurations are correct.

Okay, I found it. If you were me, would you remove the XLR's and solder up DB25 OR, use a short DB25 to XLR and connect the XLR's to each other?

It all depends on what you want to accomplish. Personally I would rather have DSUB->DSUB cables for the cleanest install, including wall plates, and then use DB25->XLR (or whatever) breakout snakes to connect my gear and mics. For example:

Control Room to Live Room Wall Plates = DB25
Converters to Mixbay = DB25
Mixbay to gear = DB25->XLR (or whatever the gear requires)
Live Room Wall Plates to Microphones and Headphone Systems = DB25->XLR

The most important thing is to get the Mixbay into your studio and start figuring out what wiring schemes work best for your environment.
