Operating Manual - DLM-821 Stereo Ducking Line/Microphone Mixer

5.CONTROLS

5.1Ducking Enable

Pressing this switch enables a signal present on inputs 1 or 2 to duck (attenuate) the signals on inputs 3 through 8. See sections 5.14 through 5.17 for internally selecting different ducking configurations.

5.2Channel Level and Pan

The inner knob is the individual channel volume control which feeds a channel to the main mix. The "5" position corresponds to unity gain. The outer knob is the Pan control and adjusts the position of the channel in the stereo mix.

5.3Mute 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.

5.4Mic/Line Switch

This recessed switch on the first four inputs in- creases the channel input sensitivity by 30 dB to allow the use of low impedance microphones. The adjacent yellow LED on indicates the switch is depressed and 30dB of gain is added for that channel's mic input.

5.5Output 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 all input channels, making it possible for these indicators to illuminate even with the stereo output level turned off.

5.6Stereo Output Level and Pan

This is the main master gain which sets the oper- ating level for the entire mixer. The "5" position corre- sponds to unity gain. This control does not effect the mono output level.

5.7Stereo 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 DLM-821 is used as

asub-mixer.

5.8Mono and Headphone Level

The inner knob is the master gain control for the mono output, which is the combined signal of the left and right outputs. It has no effect on the stereo output. Note: The mono output level can be selected between mic or line level. (see sec. 5.10) The outer knob is the level control for the front panel headphone jack.
