Ok--wait, what? Let's clarify your cabling:
Your mixer has 1/4" and XLR ins, balanced or unbalanced 1/4" outs. For
source input purposes:
>From multitrack: should be 1/4" TRS (if the multitrack has balanced outs)
to 1/4" TRS. Use regular 1/4" TS if the multitrack has only unbalanced
outs.
>From the CD players: you've probably got RCA outs from the CD player, so
either, use the RCA to 1/4" TS adaptors I think you're talking about, or go
invest $15 in a pair a good RCA to 1/4" cables.
>From the DJ mixer: again, probably RCA outs. Use the above cable
>solution.
If by chance the mixer has 1/4" outs, they will definitely not be balanced,
so use regular 1/4" TS cables.
For outputs:
To the amp: your mixer provides balanced outs, so if your amp does, use
1/4" TRS, else stick with basic 1/4" TS.
To the speakers: use the thickest gauge you can fit into your speakers'
binding posts (or whatever connector they might have--banana, 1/4",
whatever...)
To the tape player: I'd use the same 1/4" TS to RCA cables mentioned above
to run the CR out to the tape deck (or CD burner, or DAT, or whatever your
stereo mixdown destination is).
I agree with Hans: avoid the adapters.

Wow, Excellent Lindsay. Thank you.
I will do some thorough testing now with this info. It's a very helpful at
approach to use to resolve the muddy mono monitor sound problem (thought it
doesn't affect recording or headphones).
I am using phono to RCA adapters on the control room outs which are plugged
into the TRS balanced phono outs. Aha? could be poorly wired +/- adapters.
In considering the best cable for main outs or control outs, I wonder what
type of cables to use if cabling from the balanced TRS phono outs to a
non-balanced input such as a tape deck.
non balanced cables or TRS phono balanced to non-balanced?
