5.CONTROLS

5.1Channel Level

This is the individual channel volume control which feeds a channel to the main mix.

5.2 Channel Pan

This control adjusts the position of the channel in the stereo mix.

5.3 Mic/Line Switch

This switch on the first two inputs increases the channel input sensitivity by 30 dB to allow the use of low impedance dynamic microphones.

5.4 On/Off Switch

This switch on each channel will turn the chan- nel completely off allowing the channel level to remain at its desired setting when the input is not needed.

5.5 Output Meters

Apair of peak detecting 6-segment LED meters are used to indicate output level. Green LED's are used below 0 VU, yellow above 0 VU, and red LED's indicate clipping. This meter pair monitors the main stereo out- put (0 VU = +4dBu). The red clipping LED's also moni-

tor the summing amplifiers, making it possible for these indicators to illuminate even with the stereo output level turned off.

5.6 Stereo Output Level

This is the main master gain which sets the oper- ating level for the entire mixer. This control does not effect the mono output level.

5.7 Stereo Output Mute

This switch entirely mutes the main stereo out- put. The headphone and mono output are not affected. This is particularly useful when the LX-308 is used as a sub-mixer.

5.8 Mono Level

This is the master gain control for the mono out- put, which is the combined signal of the left and right outputs. It has no effect on the stereo output.

5.9 Stereo Headphones Level

This adjusts the volume level of the front panel headphone jack.

5.10 Power Switch

This switches the AC power to the LX-308B. When it is pressed in the adjacent LED will become lit.
