Owner's Manual 45. AFL Solo Switch 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, etc.), 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. Metering, Matrix, and Power LEDs 47. POWER Indicators These four LEDs indicate the status of the internal power supply voltages. The +15V and -15V supplies power the audio circuits, the +48V is the phantom power applied to the XLR MIC inputs (when the 48V switch is pushed in on the channel strips), and the -12V supply powers some internal relay circuits and the lamp connectors. Remember, PFL solo mode always overides 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. 46. GROUP/AUX FLIP Switch This switch "flips" the controls for the Aux Sends and the Group Sends, so that the Group Faders control the Aux Send levels, and the Aux Send GAIN controls adjust the Group levels. The Group signals still appear at the GROUP SEND outputs and the Aux Send signals still appear at the AUX SEND outputs. This allows you to use the long-throw (100 mm) Group Fader to make more precise settings for the Aux Sends, if required. The following chart shows what happens to each control in the Aux Send and Group sections when the GROUP/AUX FLIP Switch is pushed in: When all four LEDs are lit, you know that the internal power supply (or the external redundant power supply, if connected) is operating correctly. 48. SOLO Meters POWER The Onyx SOLO +15V -15V +48V +12V meters are made up of two columns of twelve LEDs, with three colors to indicate different ranges of signal level, traffic light style. They range from 20 CLIP 20 10 10 7 7 4 4 2 2 0 0dB=0dBu 0 2 2 4 4 -30 at the bottom, to 0 7 7 in the middle, to +20 10 10 (CLIP) at the top. 20 20 30 30 If there are no channels in SOLO, the meters won't do any- SOLO PFL AFL RUDE SOLO LR thing.
