This state of the art mixer is backed by a three-year warranty, excluding crossfader and channel slides. We know youre anxious to hook everything up and start mixing beats and cranking up the volume on those hot dance tracks, but we suggest reading this instruction manual first as there are really cool features on this mixer that we wouldnt want you to miss! The EX-26 Mixer features a crossfader which controls a super-quiet photo coupler to give you smooth operation and the cleanest possible sound, along with a hamster switch that is easily accessible on the front of the mixer. This “hamster” switch reverses the direction of the main crossfader. This mixer also features individual “hamster” switches for the separate channel input faders as well. For additional information, refer to the diagrams on pages 1 & 2 for crossfader adjustment and channel slide curve. 2 Stereo Channels State of the Art Cue Section 2 Phono & 2 Line Inputs Channel Slide Curve Control Crossfader with Curve Control Adjustable Input Assign Switches Crossfader Reverse (Hamster) Button Individual Channel Fader Reverse (Hamster) Buttons LED Display Gain, High, Mid and Low tone controls for each channel Balanced and Unbalanced Master Outputs Record outputs 1. All operating instructions should be read before using this equipment. 2. Treat this unit as you would any other piece of electrical equipment and use good common sense! 3. To reduce the risk of electrical shock, do not open the unit. There are NO USER REPLACEABLE PARTS INSIDE. Please refer servicing to a qualified service technician. INTRODUCTIONFEATURES 4. Do not expose this unit to direct sunlight or to a heat source such as a radiator or stove. 5. This unit should be cleaned only with a damp cloth. Avoid solvents or other cleaning detergents. 6. When moving this equipment, it should be placed in its original carton and packaging. This will reduce the risk of damage during transit. 7. Do not expose this unit to rain or moisture. 8. Do not use any spray cleaner or lubricant on any controls or switches. Okay, lets hook everything up! 1. Make sure that the POWER (1) switch is in the “OFF” position. This unit comes supplied with a 15 volt AC adaptor. Plug the adaptor into the rear panel power jack. Then plug the adaptor into your power strip or outlet. 2. The EX-26 mixer is supplied with 3 sets of output jacks. The BALANCED MASTER OUTPUT (2) jacks are used to connect to your main amplifier using standard cables with 1/4” connectors. We recommend using the balanced amp outputs if the cables to your amp are 25 feet or more. BALANCED MASTER OUTPUTS have three separate conductors, two of which are signal (positive and negative) and one shield (ground). The balanced line uses a tip-ring-sleeve connection. Tip = hot or positive (+), ring = cold or negative (-), and sleeve = shield/ground. The MASTER OUTPUT (3) jacks are unbalanced and are also used to connect to your main amplifier. The REC OUTPUT (4) jacks can be used to connect the mixer to the record input of your recorder enabling you to record your mix. CAUTIONSIn the U.S.A., if you have any problems with this unit, call 1-732-738-9003 for customer service. Do not return equipment to your dealer. CONNECTIONSRadioFans.CN 收音机爱 好者资料库 Page 2 3. On the rear panel are 2 stereo LINE (5,6) inputs and 2 stereo PHONO (7,8) inputs. The phono inputs will accept only turntables with a magnetic cartridge. GROUND SCREWS (9) for you to ground your turntables are located on the rear panel. The stereo line inputs will accept any line level input such as a CD player, cassette player, etc. 4. Headphones can be plugged into the front panel mounted PHONES (10) jack. 1. POWER ON: Once you have made all the equipment connections to your mixer, press the POWER (1) switch. 2. CHANNEL 1: The GAIN (11), HIGH (12), MID (13), and LOW (14) controls allow you to fully adjust the volume and EQ of the sound source. The Channel 1 REVERSE SWITCH (15) allows you to reverse the direction of the Channel 1 slide fader. (17) The Channel 1 SLIDE FADER (17) controls the input level of this channel. 3. CHANNEL 2: The GAIN (11), HIGH (12), MID (13), and LOW (14) controls allow you to fully adjust the volume and EQ of the sound source. The Channel 2 REVERSE SWITCH (16) allows you to reverse the direction of the Channel 2 slide fader. (18 ) The Channel 2 SLIDE FADER (18 ) controls the input level of this channel. 4. EQ CONTROLS: There is Low, Mid and High equalization for each channel with an extremely wide range of adjustment. 5. INPUT ASSIGN SWITCHES: You can adjust the position of the INPUT ASSIGN SWITCHES (21, 22) to move left to right, up and down, or at a 45 degree angle. Make these adjustments with the power OFF. 1) Remove the channel slide knobs, crossfader knobs and the 4 screws from the sides of the lower faceplate. Then remove the lower faceplate. 2) Remove the 2 screws in the corners of the assign switch plate. Rotate the switch plate to the desired position, and replace the screws and tighten down. 3) To position the switch at a 45-degree angle, you need to reposition the switch on the assign switch plate. First, remove the 2 screws in the corners of the assign switch plate. Then, lift the switch plate up and remove the 2 smaller screws next to the switch. Rotate the switch plate to the right until the 45-degree holes align with the switch holes, replace the screws and tighten down. Replace the switch plate and tighten down. NOTE: Keep track of where you position the input assign switches. OPERATION6. CHANNEL SLIDE CURVE SWITCHES: Use the 3 position CHANNEL SLIDE CURVE SWITCHES (23,24) to adjust the kind of curve the channel slides have. Move the selected channel slide curve switch to the 6 (top) position to make the increase in level gradual and even. Move the channel slide curve switch to the 20 (center) position to make the increase in level less gradual as you move channel slide up. Move the channel slide curve switch to the 30 (bottom) position to make the increase in level even less gradual, especially at the top of the slide. 7. CROSSFADER SECTION: The CROSSFADER (25) allows the mixing of one source into another. The left side of the CROSSFADER (25) is CHANNEL 1 and the right side is CHANNEL 2. The CROSSFADER CURVE CONTROL (26) allows you to adjust the kind of curve the crossfader has. Move the CROSSFADER CURVE CONTROL (26) to the right to make the curve steep and cutting (perfect for scratching). Move the CROSSFADER CURVE CONTROL(26) to the left to make the curve gradual and gentle. The CROSSFADER REVERSE BUTTON (27) allows you to reverse the crossfader so that CHANNEL 2 is controlled by the left side of the crossfader and CHANNEL 1 is controlled by the right side of the crossfader. When REVERSE is activated the REVERSE LED (28) will light. NOTE: When the CROSSFADER REVERSE BUTTON is activated (depressed), only the crossfader reverses. The Channel Slides, Gain, and EQ controls do not reverse. 8. OUTPUT CONTROL SECTION: The level of the MASTER OUTPUT (2, 3) is controlled by the MASTER CONTROL (20). The BALANCE CONTROL KNOB (19) controls the balance between the output of the left and right channels. NOTE: The RECORD OUT (4) has no level control. The level is set by the channel slides and the gain controls of the selected channel. The EQ of the channels is set by the low, mid and high controls of that same channel. 9. CUE SECTION: By connecting a set of headphones to the PHONES JACK (10), you can monitor the music coming out of each channel separately or both channels together. Move the CUE FADER (29) to the left to hear CHANNEL 1 and to the right to hear CHANNEL 2. Move the CUE FADER (29) to the center to listen to both channels together. The PHONES MUTE BUTTON (30) will instantly mute your cue mix. 10. DISPLAY: The red LED in the center of the display tells you that the power in your EX-26 Mixer is on. The multi-colored LED DISPLAY (31) on either side of the center tells you the output level of your 2 channels. Okay, thats it! NOW youre ready to grab a couple of great CDs or records, crank it up and get the party started!
