Owner's Manual Use these jacks for convenient playback of mixes. You'll be able to review a mix, and then ­rewind and try another pass without ­r­ epatching or disturbing the mixer levels. You can also use these jacks with a CD player to feed m­ usic to a PA system b­ etween sets. WARNING: Pushing tape to main mix [41] in the output section can create a feedback path between tape input and tape output. Make sure your tape deck is not in record, record-pause or input monitor mode when you engage this switch, or make sure the tape in level knob is fully counterclockwise (off). 13. Main Insert These 1/4" jacks are for connecting serial ­effects such as compressors, equalizers, de-essers, or filters. The insert point is a­ fter the mix amps, but before the main mix [37] fader. Insert cables must be wired thusly: Tip = send (output to effects device) Ring = return (input from effects device) Sleeve = common ground 14. Main Outs These 1/4" jacks are usually patched to the ­inputs of your 2-track mixdown deck (unless you've chosen to use the tape output [11] RCA jacks), or to the house amplifier during live sound s­ essions. To learn how signals are routed to these outputs see main mix [37] fader details on page 19. To use these outputs to drive balanced inputs, connect 1/4" TRS (Tip-Ring-Sleeve) phone plugs like this: Tip = Positive (+ or hot) Ring = Negative (- or cold) Sleeve = Shield or ground To use these outputs to drive unbalanced ­inputs, connect 1/4" TS (Tip-Sleeve) phone plugs like this: Tip = Positive (+ or hot) Sleeve = Shield or ground 15. Mono Out It happens to everybody sooner or later: The forces that govern your world will demand a monaural output from your painstakingly-c­ reated stereo panorama. The last thing you want to do is start twirling all your carefully-placed pan settings to one side. What to do? Stick a cord in this 1/4" jack, hand the other end to Mr. Mono, and you're done. He's got his mono mix and you've still got your stereo mix. The mono output is nothing more than a mix of the left and right main mix. 16. Mono Level So, Mr. Mono comes running back, screaming about the mono mix being so loud that his camcorder is melting. Just reach for this knob and turn it down a bit. Just the thing for sending mono signals to mic inputs like camcorders, telephone interface boxes, even answering machines. With the pot all the way up (fully clockwise), you'll have 6 dB of extra gain, with unity gain halfway between the one and two o'clock positions. 17. Voltage Selector Located on the bottom panel, is a voltage selector switch. 17 WARNING: Before you plug the AC power cord into the 1604VLZ4, you must make sure that this slide switch is set to the same voltage as the local AC mains supply. Only slide the voltage switch with the power cord unplugged. Use a flat headed screwdriver to slide the switch if needed. The switch allows you to use the mixer in different countries and voltages, meet interesting people from other cultures, and entertain them. 18. Power Connection Just in case you lose the cord provided with the 1604VLZ4, its power jack accepts a standard 3­ -prong IEC cord like those found on most professional recorders, musical instruments, and computers. WARNING: Before you plug the AC power cord into the 1604VLZ4, you must make sure that the voltage selector [17] slide switch is set to the same voltage as the local AC mains supply. WARNING: Disconnecting the plug's ground pin can be dangerous. Don't do it. Owner's Manual 13
