OPERATORS MANUAL MP 24x DJ MIXER QUICK START Don't! Quick-starting an MP 24x is like trying to quick-start a 747. It's just not something you do. Trust us, you don’t want to make mistakes with this sucker. So just this once—please—we highly recommend you read this entire manual: front-to-back, every single page, every single word. It will familiarize you with the many intricacies of the MP 24x, not to mention all the nooks and crannies.
FRONT PANEL DESCRIPTION 1. POWER “ON” indicator: This yellow LED illuminates anytime the MP 24x is connected to an appropriate power source (see #28, Rear Panel). 2. SOURCE CONTROL selectors: These four position rotary switches provide Input selection between the various Phono and Line Inputs for their respective mixing Channels. 3. Input channel faders: These faders control the relative Levels of each of the four Input mixing Channels. 4.
12. Microphone equalization controls: These three rotary controls adjust the frequency contour of both Microphone Inputs. They have no effect on any other program material. 13. LOOP ENGAGE switch: This pushbutton controls the Switchable Effects Loop; pressing it to its down and locked position routes the main signal through the processor attached to the SWITCHABLE LOOP connectors on the rear.(See #12 & #13, Rear Panel.) 14.
REAR PANEL DESCRIPTION 1. BALANCED MAIN OUTPUT connectors: These three-pin connectors provide a fully balanced Main Output signal, pin 2 is (+), pin 3 is (–) and pin 1 is signal ground. Pin 3 must never be grounded for unbalanced operation. Use only pin 2 as hot and pin 1 as return for any unbalanced operation. 2. UNBALANCED MAIN OUTPUT connectors: These ¼" unbalanced connectors provide MAIN OUTPUT signals. 3.
12. SWITCHABLE LOOP SEND jacks: Use these ¼" unbalanced Left and Right Outputs for driving the inputs of a processor activated by the front panel LOOP button. 13. SWITCHABLE LOOP RETURN jacks: Use these ¼" unbalanced Inputs for receiving the outputs of the above device. 14. MAIN EFFECTS LOOP SEND jacks: These ¼" unbalanced connectors provide drive to the inputs of a signal processor which is not to be switched from the front of the mixer.
MP 24x CONNECTION Even though the system variations are limitless in most applications where the MP 24x is used, an installer must follow some basic interconnect guidelines. Unfortunately, even though the system and the primary components such as mixers, processors and amplifiers are of commercial grade, most of the source components, i.e. turntables, disc players, tape decks and so on are consumer grade, with consumer interconnect limitations.
OPERATING INSTRUCTIONS INITIAL OPERATION Operation of the MP 24x is fairly straightforward, deviating only slightly from other products of its type. Assuming at least one turntable is connected and assigned to PHONO 1, operation consists of the following: Make sure all faders are set to zero, the MIC, LOOP, EQ, and ACTIVE CROSSFADER are all disengaged, (switches out) and that all rotary LEVEL controls are either fully CCW or in their center detents, whichever applies. Select PHONO l on Input Channel 1.
MICROPHONE OPERATION To use the mic, connect it to the appropriate connector, and set the PHANTOM POWER switch to the desired mode (it’s a good idea to have the Phantom Power in the on position for condenser mics, off for dynamics). Leave the MASTER LEVEL fader in roughly the same location as it was for the music that’s been playing, press the MIC ENGAGE switch and slowly adjust the MAIN MIC (or AUX MIC) LEVEL.
