44.LOW EQ:
A shelving type of active tone control that varies the bass frequency levels +/-15 dB at 70 Hz. It will add depth to thin signals or clean up muddy ones.
45.MON 1:
Adjusts the level of the channel signal (pre-EQ) that is added to the Monitor 1 mix. This is a mono mix of the left and right signals in the stereo channels. The center detent is the unity gain position.
46.MON 2:
Adjusts the level of the channel signal (pre-EQ) that is added to the Monitor 2 mix. This is a mono mix of the left and right signals in the stereo channels. The center detent is the unity gain position.
47.EFFECTS 1:
Adjusts the level of the channel signal that is added to the Effects 1 mix. It is post-fader, designed for use as an effects send, that can also be used for another monitor send. This is a mono mix of the left and right signals. The center detent is the unity gain position.
48.EFFECTS 2:
Adjusts the level of the channel signal that is added to the Effects 2 mix. It is post-fader, designed for use as an effects send, that can also be used for another monitor send. This is a mono mix of the left and right signals. The center detent is the unity gain position.
49.PAN:
Sets the channel's position in the L-R stereo field.
50.MUTE:
Mutes all channel bus sends (Mon1, Mon2, EFX 1,EFX 2, Left and Right) when depressed. The PFL signal is independent of this switch, and can be used to check the channel and adjust its input gain even when muted. The Mute/Peak LED will glow red continuously when the corresponding channel is muted.
51.MUTE/PEAK LED (red):
Normally indicates that the channel signal level is nearing the overload point. This circuit monitors the input gain, equalization, and post-fader stages for overload. It illuminates at +19 dBu and warns that gain or EQ boost should be reduced. There is roughly 2 dB of headroom remaining when it lights. If the Mute switch (50) is depressed, it lights continuously to indicate that this channel has been muted.
52.SIGNAL/PFL LED (yellow):
Normally indicates that a signal is present in the channel of –20 dBu or greater. If the PFL switch (53) is depressed, it lights continuously to indicate that this channel has been assigned to the PFL mix.
53.PFL:
Connects the channel’s pre-fader signal to the PFL mix and switches the headphone source from the L-R mix to the PFL mix. It also connects the PFL signal to the L-R meters to aid in the setting of the input gain (40). The Signal/PFL LED will illuminate when this switch is pressed to identify the PFL source.
