More 488 stuff
Yes, you certainly can keep your mic plugged into one input and record on any track. I do this all the time. That's what the "Assign" switch and pan knobs will allow you to do. In record mode, "Assign" and pan tell the machine where the signal is to be routed to.
Let's say you want to record a miked signal onto track 8:
1. Plug your mic into the channel 1 input. Press the "Assign" switch for 3-4 (since track 8 is part of Group 4. Remember GRP1 = tracks 1&5, GRP2 = 2&6, GRP 3 = 3&7, GRP 4 = 4&8).
2. Next, turn the channel 1 pan contol to the right because you're sending the signal to an even-numbered track. Again, left pan = tracks 1,3,5,7; right pan = tracks 2,4,6,8.
3. Activate the record ready button on track 8.
4. Turn up the gain control on channel 1 to somewhere between the 12 o'clock - 2 o'clock position.
5. Bring up both the master faders and the channel 1 fader to about 7 (there should be a shaded area on each fader).
6. Now, speak into the mic while looking at the display. You should see a signal for track 8.
As for using an external preamp, you shouldn't have to, but if you happen to have one of those then it's MUCH better to use that than the cheesy built-in preamps on the 488. This is pretty much true for most all multitrack machines - even the digital ones. That's one area where the manufacturers cut costs. Alternatively, if you happen to have a small Mackie mixer like
the 1202VLZ, you'd be much better off using the mic pre's in that. At any rate, the general rule-of-thumb when miking is to get as hot a signal as possible FROM THE SOURCE. If you're miking a guitar amp, for example, turn up the amp or re-position the mic before you go turning up the trim on the 488. The less trim you can get by with, the better. Less trim = less noise.
Finally, don't be afraid to experiment. Pop a fresh tape in, and have a go. That's usually the best way to figure out stuff on these machines. There's really nothing you can damage by doing so. Personally, I think they're pretty fun to use.
Let me know how it goes. Hope this helps.
