32-3008.fm Page 6 Thursday, April 6, 2000 4:03 PM ˆ Preparation PRESETTING THE CONTROLS CONNECTING INPUTS Warning: A sudden high output from the mixer could damage your hearing, especially if you use headphones, and might also damage the audio devices connected to the mixer's output. Before using the mixer, make sure you set your receiver/amplifier's volume control to its minimum volume level setting. Before you connect the power cord, make sure you set POWER to off.
32-3008.fm Page 7 Thursday, April 6, 2000 4:03 PM Connecting Microphones You can connect two microphones (not supplied) to the mixer. Connect a microphone with an XLR plug to DJ MIC on the top panel’s upper left corner. Connect a microphone with a 1/4-inch (6.35 mm) plug to AUX MIC on the back panel’s lower right corner.
32-3008.fm Page 8 Thursday, April 6, 2000 4:03 PM 6. After you finish mixing, turn down the volume on the output audio devices, turn off the input and output audio devices (amplifiers, tape decks, and so on), then press POWER so it pops up to turn off the mixer. The POWER indicator turns off. Notes: • If you did not connect an input source to every jack or do not want to mix every input source connected to the mixer's input jacks, you do not need to preset every channel input.
32-3008.fm Page 9 Thursday, April 6, 2000 4:03 PM Notes: Notes: • If it was necessary to set the channel volume level slide control to 10 to get a reading of up to 0 on the VU meter, then slide it down to about 8 and adjust the GAIN control to get a reading of up to 0 on the VU meters. (See “Using Gain” on Page 11.
32-3008.fm Page 10 Thursday, April 6, 2000 4:03 PM Important: Note the AUX LEVEL setting, so each time you want to mix that source you can set the control to the correct setting. Notes: To avoid sudden and inaudible sound outputs from any audio devices that you connect to the mixer, be sure to set their power controls to off and any tone controls to flat.
32-3008.fm Page 11 Thursday, April 6, 2000 4:03 PM 4. Set the desired channel volume level slide control to the preset position. • To mix any two inputs selected by the ASSIGN switches, set each ASSIGN switch to the desired channel. Then use CROSS FADER to mix the two. 5. Adjust CUE LEVEL to a comfortable listening level. • Do not slide CROSS FADER to the center if you want to monitor one channel while the other is playing.
32-3008.fm Page 12 Thursday, April 6, 2000 4:03 PM Note: We recommend you not adjust the GAIN controls after you have preset the inputs as some sound imbalance could occur. Setting the Sound Balance BALANCE 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.
32-3008.fm Page 13 Thursday, April 6, 2000 4:03 PM The echo is applied to the sound before all the inputs are mixed. Playing Input Signals through the Sound Effect Device Set ECHO to MIC to turn on the echo effect for the microphones and the AUX LINE input. You can play inputs selected by the channel selectors, DJ MIC, or AUX through other sound effect devices connected to the mixer, such as an echo reverb or a digital sampler processor, and control playback through the mixer.
32-3008.fm Page 14 Thursday, April 6, 2000 4:03 PM ˆ Care REPLACING THE FUSE To enjoy your mixer for a long time: • Keep the mixer dry. If it gets wet, wipe it dry immediately. Your mixer requires a 250-volt, 0.5-amp fuse to protect it from power surges and short circuits. If the mixer suddenly turns off or will not turn on, the fuse could be blown. Replace the fuse with a 0.5-amp, 250volt, fast-acting, 11/4 x 1/4 inch fuse (not supplied).
32-3008.fm Page 15 Thursday, April 6, 2000 4:03 PM Problem Possible Solution You are getting a hum from other input source Make sure there are no low-level inputs connected to the LINE input jacks. You are getting feedback noise. Move the microphone further away from the output speakers or use a unidirectional microphone. ˆ Specifications Input Sensitivity/Impedance DJ MIC (XLR jack) ............................................................. 1.
