Owner's Manual 71. AFL Solo Switch Rear Panel The AFL switch allows you to hear the Group signal through your headphones or monitor outputs. This comes after the Group Fader and before the MUTE switch, so you can hear the relative signal level on each Group even when they are muted. When you engage the AFL switch on two consecutive odd/even Groups (i.e., 1 and 2, 3 and 4), the soloed signal appears in stereo in the headphones and monitor outputs. This is useful when you are using a pair of Group Sends in stereo to feed an in-ear monitoring system. Remember, PFL solo mode always overrides AFL solo mode. If you engage a PFL solo switch on a mono or stereo channel, the AFL solo is disconnected from the headphones and monitor outputs and replaced with the PFL signal. The Rude Solo LEDS below the SOLO meters indicate which solo mode is active. 72. MAIN MIX Fader This is the master fader that control the levels at the MAIN OUTS. When MAIN TO MON [51] is selected in the PHONES/ MONITOR Section, the MAIN MIX fader also controls the main mix level in the PHONES and MONITOR outputs [46/78]. When the fader is fully down, the MAIN MIX is off. The "U" marking indicates unity gain, and fully up provides 10 dB of additional gain. Typically, this fader is set near the "U" label and left alone, but it can be used for song fade-outs or quick system-wide mutes. This is where all the connections are made to the Onyx 4•Bus (except the headphones and lamps). 73. MIC Input This is a female XLR connector, which accepts a balanced microphone input from almost any type of microphone. The microphone preamps feature our new Onyx design, with higher fidelity and headroom rivaling any standalone mic preamp on the market today. The XLR inputs are wired as follows: Pin 1 = Shield or ground Pin 2 = Positive (+ or hot) Pin 3 = Negative (- or cold) The MIC inputs can accept a balanced line-level input when the PAD [1] switch on the channel strip is pushed in (the input impedance is lower than the LINE input). 74. LINE Input This is a 1/4" TRS connector, which accepts a balanced or unbalanced line-level input signal from almost any source. When connecting a balanced signal to the LINE inputs, wire them as follows: Tip = Positive (+ or hot) Ring = Negative (- or cold) Sleeve = Shield or ground When connecting an unbalanced signal, wire them as follows: Tip = Positive (+ or hot) Sleeve = Shield or ground 14 13 INSERT 12 INSERT 11 INSERT 10 INSERT 9 INSERT 8 INSERT 7 INSERT 6 INSERT 5 INSERT 4 INSERT 3 INSERT 2 INSERT 1 INSERT LINE LINE LINE LINE LINE BAL/UNBAL MIC ONYX MIC PRE BAL/UNBAL MIC ONYX MIC PRE BAL/UNBAL MIC ONYX MIC PRE BAL/UNBAL MIC ONYX MIC PRE BAL/UNBAL MIC ONYX MIC PRE LINE LINE LINE LINE LINE LINE LINE LINE BAL/UNBAL MIC ONYX MIC PRE BAL/UNBAL MIC ONYX MIC PRE BAL/UNBAL MIC ONYX MIC PRE BAL/UNBAL MIC ONYX MIC PRE BAL/UNBAL MIC ONYX MIC PRE BAL/UNBAL MIC ONYX MIC PRE BAL/UNBAL MIC ONYX MIC PRE BAL/UNBAL MIC ONYX MIC PRE 1-8 ALANCED) CAUTION Owner's Manual 21
