STEREO LIVE SOUND SYSTEM In a live sound reinforcement or a public address system (P.A. System), the input signals to the mixer will come from the microphones and instruments on the stage. Each microphone or instrument to be amplified by the P.A. system must be connected to one of the mixing console inputs. It is preferred to have as many of the stage instruments as possible plugged into the mixer. This allows for the best overall sound control of the instruments as they are mixed together and then amplified by the P.A. system. The mixer can be operated on the stage or from a remote location in front of the stage using a snake cable to bring the signals from the stage to the mixer. The advantage of the remote operation allows the performance to be monitored and mixed from the audience's perspective. THE SOUND CHECK The sound check takes some skill, but mostly patience from the performers and especially you the system operator. If you get frustrated during the sound check, the performers can lose confidence and the sound may suffer due to things missed in the sound check. The basic sound check follows this format: First test all microphones and other input devices(direct boxes, etc.) before the performers are included in the sound check. A good thing to also check here is feedback in the monitors from the microphones. Good positioning of the monitors and the use of a graphic equalizer solves most major monitor feedback problems. Now for a sound check with the performers. First set the level of each performer individually and in cases where a performer has multiple microphones, such as with drummers, set each drum mic individually then the drum set as a whole. This is also a good time to make some channel tone control adjustments to tailor the sound of the individual performers and instruments. After setting each individual, have the performers run through a song. Don't hesitate to stop the performers if something needs to be adjusted or a performer or microphone needs to be heard solo again. Remember the sound check is not a rehearsal, but a system check. It is always a good idea for the mixer operator to have a microphone to inform the performers of what is needed during the sound check. If a monitor system is being used, the mixer operator's microphone should only be heard through the monitors when addressing the on stage performers, especially if something needs to be checked during the show.

Plug the TAPE OUT on the mixer into the tape deck's inputs and the mixer's TAPE IN's to the tape deck's outputs. With an external effects processor, plug a 1/4" cable from one of the EFF SEND outputs on the mixer into the input jack on the effects processor. Then from the outputs of the effects processor, plug one or two (for stereo) cables into one of the L/R EFFECTS RETURN. OUT IN TWO-TRACK TAPE RECORDER DSP EFFECTS Select from Reverb, Flange, Chorus, and Echo. Écho includes delay times of 50,100, 150, 250, 350, and 500 milliseconds with background reverb.
