Ok here goes another damn bible sized chunk...scuse me While I rant
8 busses should be WAY more than you need. VERY few consoles have busses that you'd actually want to run audio through. Avoid using the busses if you can. Lots of companies make passive and active summing modules for cheap that are MUCH better suited for this task.
Busses are mostly for the LAZY or the beginner. I know that consoles are sold and explained that you should just hook your 8 ( or however many ) group or buss outs to their corresponding tape recorder tracks, but dont...
Proper signal chain techniques are to keep the signal path as short as possible. EVERY active device in a signal chain is an amplifier...it is also a distrotion box, and a compressor and an EQ. Sounds like a jest but its not...EVERY active device you go thru will have a serious impact on the fidelity of the original sound.
Most active devices in modern consoles are IC's and class AB ( at best). The best of these devices would instead be DISCRETE and Class A.
Simply put ( dont flame me) Discrete just means that individual semiconductors are used for the amplifying stage, instead of an IC containing zillions of circuits
Class A devices are usually considered to be best. They work by passing both the positive and negative excursions of the waveform
Class AB devices use one amplifying stage to handle the positive side and one to handle the negative side. In a class AB setup, there is a situation called " crossover distortion ". The point where the positive and negative waveforms meet WILL be slightly shifted in time a certain amount causing artefacts, filtering and distortion.
So, how do you hook up the console to the tape recorders then ? And how do you record more than 8 tracks with only 8 busses?
FORGET the part of the manual where they tell you to hook up a buss per track ...
There will usually be in any decent console a " direct out " jack. Hook these up to your tape recorder inputs. Hopefully these will be PRE fader, so that you can still use your faders to adjust your monitor mix. Some of these still pass thru a gawdawful number of amplifiers tho, so....
Maybe your console has channel inserts ? These will usually be even CLEANER than the direct outs, some are switchable pre/post EQ even Use these to your tape if you can.
Anything you arent using on the channel, bypass it or null it out. Especially EQ...try to use the mic itself as your primary EQ. Most console EQ's are so phasey that it can easily cancel a kick out of the overheads.
So heres a small reccomended setup for you:
get a couple patchbays
patchbay 1 : top row tape recorder output
half normalled to
bottom row: console tape return ( or maybe line input)
patchbay 2 : top row insert send
half normalled to
bottom row: insert return
patchbay 3: top row direct out
half normalled to
bottom row tape recorder inputs
patchaby 4: facilites like group outs, aux sends, and some outboard summing modules like a Whirlwind Combiner or some such
