We can now manage booth voicing with GarageBand using the left iMac upstairs, and the blue mixer beside it.
1) Make sure that the booth mics are plugged into the two top, left XLR ports on the mixer.
2) Two pairs of red and white cables at top, right corner of the mixer should be connected to the back of the iMac.
3) Monitor recording and playback audio with headphones plugged into the ‘PHONES” port on the mixer. This may require an adapter, depending upon the headphones you use.
4) Make sure that mixer settings match the photo below.
Set EQ controls as pictures, with “HI” and “MID” controls at “12 o’clock” and both “LO” controls at about 3 o’clock.
Two black “GAIN” controls should be dialed back just slightly to the last marker, at about “5 o’clock.”
Both “EFF/AUX” buttons should be in the DOWN position to avoid unwanted effects, like reverb.
Both “PAN” controls should point straight up to “12 o’clock.”
Level 1 and Level 2 should be pointed to about “3 o’clock” but you can adjust for each speaker.
The TWO MIDDLE COLUMNS can be used to mix in telephone inputs or portable recorders, but the best setting will depend on the source.
In the RIGHT COLUMN:
Dial “PROGRAM” to “00”
Keep the left button “DOWN” and both controls above it dialed back to “7 o’clock.”
USE MAIN MIX AS YOUR PRIMARY CONTROL TO SET RECORDING LEVELS.
(Perhaps at around 2 or 3 “o’clock.”)
USE THE BOTTOM, RIGHT CONTROL FOR HEADPHONE AUDIO VOLUME. You can TOGGLE monitoring of incoming audio with the button just above.
