3 The Basics IMPOR T ANT SAFETY INSTRUCTIONS Read Instructions — All safety and operating instructions should be read before the appliance is operated. Retain Instructions — The safety and operating instructions should be retained for future reference.
4 The Basics try reversing the plug. If the plug still doesn ’t fit, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the polarized plug.
5 The Basics * When the power -supply cord or plug is damaged. * If liquid has been spilled or objects have fallen into the appliance. * If the appliance has been exposed to rain or water . * If the appliance does not operate normally by following the operating instructions.
6 The Basics connections A sudden high output from the mixer could damage your hearing or damage the audio devices connected to your mixer . Before connecting to AC power , turn off your mixer and all audio devices connected to your mixer .
7 The Basics connecting inputs LINE 1, 2, 3, 4, 5, 6 — connect up to six audio sources to your mixer . Do not connect audio sources with line-level outputs to the PHONO 1 , PHONO 2, or AUX MIC jacks. PHONO 1/2 — connect up to two low-level audio sources to your mixer .
8 The Basics connecting a lamp, headphones and mic listening safely Do not listen at extremely high volume levels. Extended, high-volume listening can lead to permanent hearing loss.
9 The Basics using your mixer 1. Set your output device’s volume to minimum and turn it on. 2. Press POWER to turn on the mixer . 3. T urn on the audio input sources you want to mix. 4. Preset the input signal levels (see “presetting input signal levels”).
10 The Basics presetting audio inputs Before mixing your audio sources (devices connected to LINE 1, PHONO 1, PHONO 2, LINE 2 , LINE 3, LINE 4, LINE 5, LINE 6) , you must set their input signal level to each channel input ( CH1 , CH2 , CH3, etc . ). Y ou do not have to mix every connected input source.
11 The Basics 5. Slowly slide up the channel volume control ( CH ) until you get a reading of up to 0 dB on both LED meters. 6. Stop playback of the selected input source. 7. Repeat steps 1-7 for each audio input you plan to mix. Notes : • W rite down the CH setting for each audio source.
12 The Basics 2. While talking, adjust DJ MIC LEVEL or AUX LEVEL until you get a reading of less than 0 dB on both LED meters. See “using an XLR microphone” on P age 16. Notes: • W rite down the DJ MIC LEVEL or AUX LEVEL setting . Then, when you want to mix with the microphone, you can adjust it to this setting.
13 Beyond the Basics mixing inputs Y ou can select any two of your connected audio sources and mix them so one or both play through your sound system. Mixing consists of three parts: playing an input source, monitoring a second input source, and switching to a second input source.
14 Beyond the Basics monitoring a second input source Monitoring a second input source requires listening to an input source, finding the desired audio section you want to mix, and adjusting it ’s sound level to match the volume of the first input source (the one designated ASSIGN A ).
15 Beyond the Basics using a micr ophone using an XLR micr ophone T o mix the XLR microphone with other audio input sources, adjust DJ MIC LEVEL to increase or decrease microphone volume. Set DJ MIC LEVEL to 0 when you are not using the DJ microphone.
16 Beyond the Basics using the special contr ols tone Y our mixer has a set of tone controls for each microphone and channels 1– 4. Y ou can tailor the high, middle, and low frequency sounds for each. F or normal sound, leave BASS , MID , and HIGH set to 0 .
17 Beyond the Basics setting the sound balance BAL ANCE lets you adjust the sound balance between the left and right speakers. If your speakers are properly positioned and your listening area is centered between the speakers, the center setting of the control is usually the best.
18 Beyond the Basics using echo The mixer plays echo effects, and lets you adjust echo delay , number of echo repeats, and the echo’s volume. The echo is applied to the sound before all the inputs are mixed. 1. Set ECHO to MIC to apply the echo effect to the microphones and AUX LINE input.
19 Beyond the Basics playing input signals thr ough the sound effect device Y ou can play inputs selected by the channel selectors ( DJ MIC or AUX) through other sound effect devices connected to the mixer , and control playback through the mixer . T o play selected inputs through the sound effect device, set SEND ASSIGN to the selected input.
20 Beyond the Basics frequently ask ed questions Q - I set up my mixer using the instructions. Why doesn ’t it work? A - Make sure you are connected to a “live” AC outlet. - V erify that all sources are securely connected. - Check the fuse and replace it if needed.
21 Beyond the Basics replacing the fuse The mixer uses a fuse for protection against surges and short circuits. If the mixer suddenly turns off and will not turn on, check the fuse. If necessary , replace it with a 0.5-amp, 250- volt, fast-acting , 1 1 / 4 x 1 / 4 inch fuse (not supplied).
22 Beyond the Basics Specifications Input Sensitivity/Impedance DJ MIC (XLR jack) .............. 1.5mV , 600 ohms, balanced/unbalanced AUX MIC (Phone jack) ........................ 1.5mV , 600 ohms, unbalanced Phono ..................................
