You’ll need this kind for:

Main balanced outputs

Mic inputs

Nomenclature clarification:

FIELD= entire patching area

BAY= a unit of 48 jack sockets arranged as 24 outs over 24 ins

If you really want to make the most of your home studio, invest in a patchfield. 

We know that you will often put off doing a complex patch if there is no patchfield:

because it’s so much bother and

1) 

in case you inadvertently damage or pull out a lead.

2) 

Most decent jackbays offer two rows of 24 normalized jacks in a 1 U of rack space. 

Lucky you’ve got a 24/48 channel desk, eh? The term normalized refers to the fact 

that the top row (outputs) are internally connected to the bottom row (inputs), 

unless you plug something into an input socket. Plugging into the output socket 

of a normalized insert pair does not break the internal connection, but it does 

provide an alternative direct output. Where normalizing is not wanted on a 

patchbay (there are a few cases!) it is possible to remove it by cutting certain 

PCB tracks. Refer to the patchbay instructions for how to do this.

If you want to do the only decent thing and construct a patchfield for your 

studio, here’s how to do it. Note that we have laid it out in order that a minimum 

number of cables are likely to be needed. We have also completely left out the 

microphone inputs. Unlike everything else, these operate at a level several orders 

of magnitude lower than line (+4 dBu or -10 dBV). It is best to plug microphones 

directly into the EURODESK SX4882, or via special XLR-type wall boxes connected 

to the EURODESK microphone inputs by a good quality balanced (2-core + screen) 

multicore. (See also section 12 “(Un)balanced lines”.)

*

 Break the normalizing on this bay.

**

 Tie lines: usually, in a MIDI setup, racks and keyboards etc. are scattered around 

the control room. Plugging these directly into the front of the patchbay would 

result in Spaghetti Junction. Instead, it is better to connect TIE LINE jacks to wall 

boxes strategically positioned near to where MIDI hardware congregates.

***

 It’s always good to have a few 4-way links around for splitting signals up to 

3 ways (one in, three out). E.g. one tape track has four different instruments on 

it. Patch the DIRECT out of its CHANNEL into a 4-way split, returning to a further 

3 channels via LINE INPUT. Set up each of the paralleled 4 channels for one 

instrument, and use mutes (preferably MIDI controlled) to mute the 3 unwanted 

channels at any one time).

****

Break NORMALIZING LINKS here. If you’ve got more than 5 or 6 stereo 

dynamics/EQ processors, you might spill over onto another dedicated bay, 

or alternatively have to find some suitable extra space somewhere else in the 

patchfield. Remember, most dynamics processors also have sidechain/KEY inputs, 

and therefore require 3 holes per channel.

For unbalanced use, pin 1 and pin 3 have to be bridged

1 = ground/shield
2 = hot (+ve)
3 = cold (-ve)
