AFL Switch/Signal-AFL LED, Group Fader, 28 BAL

Front Panel

25AFL Switch/Signal-AFL LED

This switch connects the Group’s post-fader signal to the PFL/AFL mix. When the AFL button is in, the Group’s signal can be monitored through the headphones and/or on the PFL/AFL display. A yellow LED in the Master section will blink to indicate that the signal on the Master LED display and the Headphone Output is the PFL/AFL mix. When the AFL button is out, the yellow group LED will blink as an indication of signal presence (-30 dBu).

26Group Fader

This control varies the signal level from -∞ to +10 dB and sends the signal from the Group to the Left and/or Right buses and to the Group Output jacks (53). The optimum setting is the ø (unity gain) position.

27TO AUX 1 & TO AUX 2 Controls

These controls determine the level of the respective Effects Return signal that is sent to the respective AUX bus, allowing musicians/singers to hear internal and/or external effects in their monitors.

NOTE: Due to the creation of an electronic feedback loop, do not use AUX Sends 1 or 2 as the path to external equipment that is to be sent back to the corresponding AUX mix (1 or 2).

28BAL

This control determines the placement of the Effects Return signal's position with respect to the as- signed L/R and Group 1-4 buses. Rotating the control counterclockwise (L) sends more signal to the LEFT output and odd-numbered GROUPS; rotating clockwise (R) sends more signal to the RIGHT output and even-numbered GROUPS. The C position sends equal amounts to each.

29EFX LEVEL Control

This control determines the level of the Effects Return signal being sent to its assigned buses. It func- tions similarly to the Channel Faders (13).

301/2, 3/4, L/R Bus Assign Switches

Like the channel assign switches, these buttons determine the bus assignment of the Effects Return signal. They determine where the signal is being sent.

31Mute Switch/Mute-Clip LED

This switch mutes its respective Effects Return from being sent to the buses. This switch is equipped with a red LED that will illuminate when the Effects is muted. When the Mute button is out, the LED func- tions as a Clip indicator that will illuminate at 2 dB below clipping.

32AFL Switch/Signal-AFL LED

This switch connects the Effects Return post-fader signal to the PFL/AFL mix. When the AFL button is in, the Effects Return signal can be monitored through the headphones and/or on the PFL/AFL display. A yellow LED in the Master section will blink to indicate that the signal on the Master LED display and the Headphone Output is the PFL/AFL mix. When the AFL button is out, the yellow Effects Return LED will blink as an indication of signal presence (-30 dBu).

33Effects 2 Patch Switch

This switch determines whether the Effects 2 processor will be used in the Return 2 or will be patched to an Input Channel or Group insert point. This switch can also be used to perform the bypass function. When the effects processor is assigned to the EFX 2 Return, the I/O jack (56) is bypassed. Similarly, when the effects processor is being patched externally, only the external Stereo Return jacks (57) are used to return a signal.
