Application 2 - Using The PL 2404 As A Main Live Mixer

Here, the PL 2404’s Main output is connected to the input of a power amplifier, and, from there, to PA speakers. Microphones are connected to channels 1 and 3, while line level signals are connected to other channel inputs (stereo signals are routed to “matched” consecutive odd- and even-numbered inputs). A two-track tape deck is connected to stereo Aux return 1, while a signal processor is connected to Aux return 2, with signal being sent to that signal processor from Aux send 2. Another signal processor is connected to channel insert 1 so as to affect the signal coming from the mic connected to channel 1.

When only the odd-numbered left input is connected, the Balance knob functions as a constant level Pan control, allowing you to continuously place the incoming signal anywhere in the left-right stereo field.

If you have a microphone connected to channel 1 or channel 3, the procedure for setting optimum microphone levels is as follows sing or speak into the mic at the level you expect to use in performance while slowly raising the Level control for that channel to its 2 o’clock “0” position. Again, slowly raise the power ampli- fier volume until you reach the level you want to hear. Then raise the rear panel Trim control for that channel to a point at which you get a strong, clear signal that doesn’t distort even at the highest singing or speaking levels. For best signal-to- noise ratio, always keep the Trim control as high as possible short of distortionGrounding Techniques If you’re using the PL 2404 in a fixed location such as a recording studio, you may want to invest the time and money into creating a star ground network. This is by far the best technique for avoiding grounding problems. It involves using a formidable ground source such as a cold water pipe or a copper spike driven into the earth. A thick grounding cable is connected to that source and then brought to a central distribution point from there, individual cables are connected to each piece of equipment. This setup also requires that you lift the ground plug of all three-prong AC connectors, so there is the possibility of danger if it is done incor- rectly. We strongly recommend that you contract with a qualified professional to carry out this or any kind of electrical work Grounding TechniquesBusing, Submixing and Channel Muting Using the Balance Control L R BALANCEUsing Equalization HIGH 15 +15 MID 15 +15 LOW 15 +15Using Aux Sends and Returns Using Channel Inserts INSERTMAIN Using PFL/AFLSOLO Applications Application 1 - Using The PL 2404 As A Recording MixerSAMSON Application 2 - Using The PL 2404 As A Main Live MixerApplications SAMSON Application 3 - Using The PL 2404 As A Keyboard SubmixerApplications SECONDARY MIXER ApplicationsSECONDARY MIXER MASTER MIXERAppendix A Block Diagram AUX 3LWeight SpecificationsDimensions 3.
