Setting up your PL 2404 is a simple procedure which takes only a few minutes:

1.Remove all packing materials (save them in case of need for future service) and decide where the unit is to be physically placed—it can be mounted in any standard 19" rack, requiring four rack spaces, or used on a tabletop.

2.Before even plugging the unit into an AC socket, begin by connecting the PL 2404 Main or Control Room outputs into a power amp and the amp into loudspeakers (you’ll usually connect the Main output to a power amp in live performance environments and the Control Room output to a power amp when using the PL 2404 for recording). It is never a good idea to power up any amplifier that is not connected to loudspeakers.

3.Next, make the signal input connections to the mic or line inputs of the various channels. WARNING: When using channel 1 or 3, do not connect its microphone input and line input simultaneously; these channels are designed to accept only one source or the other.

4.Turn all channel Level controls fully counterclockwise (to their “∞” setting), bring all four bus faders completely down (to their “∞” setting), and set the Main and Control Room Level controls fully counterclockwise (to their “∞” setting.

If you are using the channel 1 or 3 mic inputs, set their Trim controls fully counterclockwise (to their “+4” setting). Then connect the EEC main power cord and plug the PL 2404 into any grounded AC socket.

5.Turn on the rear panel Power switch—the “Power” LED in the main section will light up.

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.
