7.USB PLAY/USB RECORDING This USB player can play the music in your USB memory disc as you like. Supported formats includwe WNA、WAV、MP3. The signal of the stereo's output will mix to the MAIN via the USB player channel. The recording of the live show will be store to the REC file of your USB.
4.PHONES This 1/4" TRS stereo jack will drive any standard headphone to very loud levels.Walkperson-type phones can also be used with an appropriate adapter. If you’re wiring your own cable for the PHONES output,follow standard conventions:
PLAY/PAUSE The button is for play or pause the tracks in your USB. NEXT/PLUS The button is for choosing the previous track and next track. REPEAT The button is for repeat. EQ The EQ model built-in the USB player. REC Press this button can record the signal of the MAIN MIX. If need to transform the play model can press this button fot choosing.

12.MON SEND Stage monitors allow the talented musicians to hear themselves clearly on stage,and this can often be a good thing.The monitor mix may be carefully adjusted in level using the aux mon controls [25]. These tap a portion of each channel’s signal to provide a 1/4"TRS output here to feed external stage monitors.These could either be passive stage monitors powered by an external amplifier,or powered stage monitors with their own amplifier built in. 13.STEREO RETURNS
14.FX FOOTSWITCH This 1/4"TRS connector is where to connect a footswitch.This will allow you to easily mute or un-mute the internal effects,while stamping your foot and looking like you were mad about something. Any latching one-button on/off footswitch will work. If the internal effects have already been muted with the internal FX mute switch [50],then the footswitch has no effect,but you can still stamp your foot and pout if that helps any.Cultivate that bad-boy image.

Channel Strip Description Mono Channels The mono channel controls affect both the mono mic input and the mono line-level input. The gain knob adjust both mic and line input.
16.GAIN 15 16
Each mono channel has an insert jack and low cut switch. Channel 1 has a hi-z switch to connect a guitar directly. The 3-band EQ has shelving high,shelving low,and peaking mid EQ.
“U”LIKE UNITY GAIN Theye mixers have a “U” symbol on almost every level control.This “U” stands for “unity gain,” meaning no change in signal level(0 dB gain).Once you have adjusted the input signal with the gain control,set every control at “U” and the signals will travel through the mixer at optimal levels.What’s more,all the labels on our levels cotrols are measured in decibels(dB),so you’ll know what you’re doing levels-wise if you choose to change a control’s setting.

17.HI EQ
19.LOW EQ
This control gives you up to 15 dB boost or cut above 12kHz, and it is flat (no boost or cut) at the detent,Use it to add sizzle to cymbals,and an overall sense of transparency,or edge to keyboards,vocals,guitar and bacon frying.Turn it down a little to reduce sibilance,or to hide tape hiss.
This control gives you up to 15 dB boost or cut below 80 Hz.The circuit is flat at the center detent position.This frequency represents the punch in bass drums,bass guitar,fat synth patches,and some really serious male singers.
18.MID EQ Short for “midrange,” this knob provides 15 dB of boost or cut, centered at 2.5 kHz,also flat at the center detent. Midrange EQ is often thought of as the frequencies that define any particular sound are almost always found in this range.You can create many interesting and useful EQ changes by turning this knob down as well as up.

Used in conjunction with the low cut switch,you can boost the low EQ without injecting a ton of subsonic debris into the mix.
20.AUX MON These knobs tap a portion of each channel’s signal to set up a nice monitor mix feeding stage monitors, independent of the main mix.Adjust these controls on each channel until the band is happy with the stage monitor mix.The aux mon is pre-fader.
21.AUX FX These knobs tap a portion of each channel’s signal to set up a nice FX mix feeding the internal FX processor,and to feed external processors via the FX output.
LOW CUT
The controls are off when turned full down,deliver unity gain at the center detent,and can provide up to 15 dB of gain turned fully up. The channel fader [25],mute [24] and other channel controls affect the FX output,but pan [22] does not, (The aux FX is post-fader.)
22.PAN These knobs adjust the amout of channel signal sent to the left versus the right outputs.On mono channels these controls act as pan pots.On hybrid and stereo channels,they work like the balance control on a home stereo.They do not affect the aux mon or FX mixes.
23.MUTE Press this switch in to mute the channel in the main mix.The aux mon output of the channel is not muted.

24.OL LED This LED will light if the channel signal is too high, and this may cause distortion due to overloading. The OL LED comes before the channel fader [25] in the signal path,so the fader has no effect in your efforts to turn off the OL LED. Overloading may occur if the gain [16] is set too high,Turn down the gain if it is. Overloading may also occur if the channel EQ [17-19] is set too high.Check that the EQ settings are moderate.Use the low cut switches [15] if the overloading is due to lower unwanted bass thumps and bangs.
22
23 24
25.CHANNEL FADER These faders control the channel’s level from off, to unity gain,on up to 10 dB of additional gain.The mono channels have mono faders,and the hybrid and stereo channels use stereo faders.
25
With the gain control [16] set correctly,the faders should be set around unity gain (U).

These meters have 2 columns of 12 LEDs each, with dB markings from -30 to +15,and OL (overload at +20 dBu).They indicate the stereo signal strength of the main mix after the main fader [34]. Typically,these meters should be bouncing between the “0" abd the “+3" LEDs.It is okay if the OL LEDs light occasionally,but if they light frequently or continuously,turn down the main fader until they blink occasionally or not at all. Remember,audio meters are just tools to help assure that the levels are “in the ballpark.” You don’t have to stare at them (unless you want to).

29.PHONES LEVEL This controls the volume of the headphones output from off to maximum gain. Warning:The headphone amplifier is designed to drive any standard headphones to a very loud level.It can cause permanent hearing damage.Even intermediate levels may be painfully loud with some headphones.Be careful!Always start with the phones level control turned all the way down before connecting headphones or making any connections. Keep it down until you’ve put on the headphones,and turn it down first whenever you play a new source or instrument.
30.STEREO GRAPHIC EQ 26.PHANTOM POWER SWITCH If the microphones need phantom power,press in this switch to add phantom power to all the XLR microphone inputs of the mixer.This lets the mixer send low-current DC voltage to the mic’s electronics through the same wires that carry audio.The LED will turn on as a reminder that phantom power is engaged.
27.POWER LED This LRD comes on when the mixer is plugged into the AC mains supply,and the rear panel power switch [8] is on. If the LED does not turn on,make sure the AC power is live,both ends of the power cord are correctly inserted,the electricity bill has been paid and the lights in town are on. 11
This 7-band graphic equalizer adjusts the main mix output.It affects the line-level outputs.It may also be quickly bypassed using the EQ in/bypass switch [31]. Each slider adjusts the level of its frequency band, with up to 15 dB of boost or cut,and no change in level at the center (0 dB) position.The frequency bands are: 63,125,400,1K,2K,4K,and 12KHz. The EQ section comes before the main fader [34] and meters [28].As with the channel EQ,just take it easy. There is a large amount of adjustment,and if you are not careful,you can upset the delicate balance of nature. Although it may not seem cool to actually turn down controls,with EQ it is often your best option. Turn down the offending frequency range,rather than boost the wanted range.Use it to reduce the level of some frequency bands where feedback occurs.

31.EQ IN/BYPASS Use this switch to quickly engage or disengage the stereo graphic EQ.This may be used for quick checks of EQ settings or to shorten the signal path if not using the EQ.
32.TAPE/USB
This fader controls the level of the main mix and affects the meters [28] and main line-level outputs [10,11]. The level adjustment occurs after the stereo graphic EQ [30] in the signal path. This gives you ultimate control over the audience. Adjust it carefully,with a good eye on the meters to check against overloading and a good ear on the levels to make sure the audience is happy. The main mix signals are off with the fader fully down,the “U” marking is unity gain and fully up provides 10 dB of additional gain.This additional gain will know it’s there.The level control is stereo, as it affects both the left and right of the main mix equally.This is the control to turn down at the end of the song when you want “The Great Fade-Out.”
35.FX RETURN FADER Use this fader to gently adjust the level of the stereo output from the internal FX processor being added to the main mix.The range is off to +10 dB with unity at “U”.
36.INTERNAL FX MUTE and 37.LED When engaged,the internal effects processor is muted.Its output will not appear in the main mix or monitors,and the adjacent LED will come on.The footswitch connection [15] becomes disabled and the footswitch cannot be used to mute or un-mute the effects. If this switch is not engaged,then the internal effects may be muted or un-muted with a footswitch.
38.PRESET DISPLAY This display shows the number of the currently selected effects preset,as shown in the list of presets silkscreened to the left of the display.
This determines if the 2-track return gets it’s signal form the RCA input or USB.
33.TAPE LEVEL This knob controls the input level of signals entering the tape inputs.The audio is added to the main mix.

41.MONITOR This controls the overall level of the monitor send signal sent out to the stage monitors. Adjust it carefully and check that the band is happy with the leves.The fader does not affect the main mix level. The monitor send signals are off with the fader fully down,the “U” marking is unity gain,and fully up provides 10 dB of additional gain.
42.FREQ and FILTER If you select SUB BASS,you can then use the FREQUENCY adjustment knob to adjust the cutoff frequency.The adjustment range is 25 Hz to 150 Hz.
