Operating Manual - LX-308B Stereo Line/Microphone Mixer
5. CONTROLS
5.1 Channel 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
A pair 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.
