(I hope it''m not that sure at the moment, I''ve got a Focusrite Saffire Pro 40 with a Behringer ADA8000 hooked up to it via ADAT which gives me 16 mic inputs - this is more than adequate for regular recording but for live work where the whole band is mic''t ideal and it would be simpler and quicker to use a mic splitter.

Somebody did mention to me that I could use the line-outs of the devices.....I''t there be latency?), but I''s just for recording my own band).

I guess the question is; On a scale of Maplin to Jensen, what would be the cheapest transformer that I could get away with in order to achieve a decent enough sound quality?

I think in your position I''d look at something like a couple of ART T8s. It would almost certainly be more cost effective than building your own box and buying all the XLRs and transformers... and ART stuff is generally of adequate quality for most applications.

When I was looking into getting rack splitters myself I discovered that John at Orchid Electronics has an '' unit which seemed very cost-effective and is very willing to configure a unit to individual spec. Might be worth giving him a call... very helpful and pleasant man...

Couldn''sniffer''t break the insert path?

You need a TRS plug for the insert end, which has been wired internally with the tip contact linked directly to the ring contact. That maintains the channel''t know of any ready-made cables wired this way, but they might exist. It''re best off getting your feed from splitters , as early in the chain as possible.

Close, but not quite.

The console''d probably ground the signal and mute it for both the recorder and mixer! And if you plugged into a balanced recorder you''s very unlikely, but unusually low impedance recording inputs may cause unwelcome loading effects on the desk, affecting signal levels and tone.

5. you remove the option for outboard plugins (compressors, gates, etc) at the desk

6. You are at the mercy of the live sound engineer as far as recording levels (and possibly EQ) are concerned.

So for all these reasons its important to rig and test an installation using sniffer leads beforehand, and make sure everyone is happy with the outcome! (and no one fiddles with it of changes anything -- especially the channel input gains -- once up and running).

...and the Gnome got there before me! ;)

And I agree with him that passive transformer splits at the stage is the safest way to go, albeit a much more expensive solution.

If I''m working the FoH desk then I''m in control of gains...

If I''s FoH desk - being worked by A N Other - then I''ll have a go at making some '' then.

I will pretty much only be recording my own band - we tend to do the sound ourselves and this usually consists of sound-checking the mix while one of us tweaks the desk and then it''t want to wreck SOS!
