PUNCH-IN or INSERT Recording"Punching in" or "insert recording" is when you record over a smallsection of a previously recorded track in order to fix a mistake orimprove a performance, while keeping the rest of the track as before.The mixer settings should be exactly the same as they were duringthe original recording.The 488 can manually punch-in with the RECORD (•) key, the RECORDFUNCTION switches, or the optional RC-30P footswitch.REHEARSE functionThis function is activated by pressing the RHSL switch. Its LED willstart blinking. During a rehearsal, what you hear in the monitor mixand read on the TRACK level meters will be the same as duringrecording, but signal won't be recorded on tape. The playback issimply muted while RECORD is on.You can rehearse your punch-in as many times as you need withoutaffecting the existing recording at all. When you are sure of yourperformance and ready to actually record the insert, turn off the RHSLLED by pressing the switch again.Punch-in/out procedurePreliminaryThe 488 offers 3 ways to initiate the punch-in. The first is with thetransport RECORD key, the second with the track RECORD FUNCTIONswitch, and the third with the remote foot switch.In the following, we'll use track 2 as the punch-in track as an example.1. As the punch-in track is track 2 in our example, your input needsto be assigned to GROUP 2. To do so, turn the PAN control in thechannel which your source instrument is plugged into, all the wayto the right (EVEN), and press the channel's 1/L-2/R ASSIGNswitch.Keep all the other channels' ASSIGN switches off.2. To hear the tape, the CUE signal path is used. So, turn each TAPEcontrol to the right of center (CUE side) and press the CUE switchin the MONITOR switch rack.3. To hear the instrument press the MONITOR GROUP 2 switch.4. Press PLAY to play the tape, then adjust the CUE MASTER controluntil the MONITOR level meters peak at about 0 to +3, and adjustthe PHONES control for the desired listening level of theheadphones.5. Play the instrument. You'll hear it together with the tape signals inthe headphones. Stopping the tape will allow you to hear onlythe instrument.28
