7.1Small Sound Reinforcement System
In the setup shown here, the DLM-821 is used to mix typical sound sources that might be found in a small club, school theater or similar environment. INPUT channels 1 & 2 are used for microphones for live vocal or instru- mental pickup. INPUT channels 3-8 are used for the output of electronic music devices such as keyboards, MIDI sound modules, drum machines, etc. The power amplifier (or any additional graphic equalizers or electronic cross- overs which may be used) is fed from the MAIN OUTPUT connectors.

7.2Church, School Or Meeting Room Sound System:
Here the DLM-821 is used to mix sources typically found in a church, classroom, or meeting room. The channel 2-4 inputs are used for microphones for live vocal or instrumental pickup. Channel 1 is fed by an alarm signal which will have priority and fully attenuate all other inputs if it is receiving an input signal. Channels 1 through 4 will have their Stereo/Mono switch pushed in. The remaining INPUT channels are used for audio outputs from video/DVD players, cassette deck, CD player, computer sound card, etc. One input channel is reserved as a spare. The power amplifier (or any additional equalizer or electronic crossover which may be used) is fed from the MAIN OUTPUT connectors. The Mono output is connected into the wall mic jack to feed the mix into the building's main PA system.
Here the Mono Output selector switch should be pushed in for a mic-level signal.
