STEREO INPUT CHANNELS

14Mic Gain

This control establishes the nominal operating level for the mic input (XLR) of the channel. The mic gain can be adjusted over a wide range (0 dB – 60 dB) to compensate for soft voices or very loud drums. To maximize the signal-to-noise ratio, the gain should be set to the proper level, with the Channel Fader (13) set to ø. The mic gain can be set by pressing the PFL button (12) and adjusting for ø dB on the output meter. If the clip LED comes on and remains lit, reduce the gain.

15Stereo Gain

This control establishes the nominal operating level for the stereo line inputs (1/4" jacks) of the channel. The Stereo Gain can be adjusted over a sufficient range (-∞ to +20 dB) to accommodate almost any input level. It operates in conjunction with the L/R–CH Switch (16) to route the stereo signal directly to the L/R buses or through the channel strip.

	When the switch is out, the stereo line input signal is routed directly to the L/R
	buses, bypassing the channel strip. In this mode, the mic input (XLR) signal is routed through the
	channel. When the switch is in, the stereo line input signal is routed through the channel and the mic
	input signal is disconnected. The signal level is controlled via the Stereo Gain control (15).

17Input Select Stereo-USB Switch

This switch selects the input signal that will feed the stereo line input of the second stereo channel. When the switch is out, the signal from the stereo line inputs is routed to the Stereo Gain control (15). When the switch is in, the signal from the device connected to either USB port (60-61) is routed to the Stereo Gain control (15).

18Mid EQ

In the Stereo Input channels, this active tone control is a bandpass (peak/notch) type that varies mid-frequency response by ±15 dB at a center frequency of 850 Hz.

MASTER SECTION

19Auxiliary Masters 1-4

This control sets the output level of the AUX 1-4 mixes and is adjustable from -∞ to +10 dB.

20Auxiliary Masters 5-6

This control sets the output level of the various AUX 5-6 mixes and is adjustable from -∞ to +10 dB. These signals are also sent to the EFX1 and EFX2 internal effects processors, respectively.

21AFL Switch/AFL-Clip LED

This switch directs the post-fader (AFL) signal to the Headphone output (37) and activates the PFL/AFL LED display. An adjacent red LED illuminates to signify this selection. If AFL is not selected, the LED functions as a Clip indicator. Selecting AFL allows monitoring of AUX Masters with the full PFL/AFL Level Display as well as allowing the operator to hear the output.
