OWNER’S MANUAL MP7 ENTERTAINMENT SYSTEM
IMPORTANT SAFETY INSTRUCTIONS The lightning flash with arrowhead symbol, within an equilateral triangle is intended to alert the user to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintance (servicing) instructions in the literature accompanying the appliance.

INPUT/MONO 1. MIC Electronically balanced XLR-type inputs (identical to the ones found on major studio and live sound mixing consoles) for connecting low-impedance microphones. The input stage provides extremely low noise and low hum signal processing at an outstandingly low distortion rate (<0.002% typically) even in the high frequency range. Generally, any type of microphone can be connected as long as its pin assignment is in accordance with the diagram shown aside.
INPUT/MONO Another welcome side effect is, that the power amplifier and the connected loudspeaker systems are not “polluted” by low-frequency interference “closing off” the sound system, which certainly is not in yours or the audience’s interest. Your speaker systems will provide you with a truly clear, natural, and powerful sound performance when using the Lo CUT filter. 4.
INPUT/MONO 6. PAN The setting of the PAN control defines the input signal’s position within the stereo image. When set to its center position, the audio signal is fed with equal levels to the left and right master busses. The PAN section’s design ensures that the overall relative level of an audio signal is maintained, no matter to what position within the stereo image the PAN control is set. 7.
INPUT/MONO 11. VOLUME The channel fader is used to set the volume of a single channel and to establish an accurately proportioned mix of all input signals. The channel faders should be positioned within the range of -5dB to 0dB, leaving you with a sufficient degree of control to allow precise matching of relative big differences in the channel’s level settings. Afterwards the overall volume is set through the use of the master fader.
INPUT/STEREO 13. STEREO INPUT A (CD/MD): Unbalanced stereo inputs for connecting LINE level devices like for example: CD-Players, MD-Players, Tape Decks, PC Soundcards, etc. B (phono): only channels 4/5 - stereo inputs with RIAA equalization for the connection of magnetic turntable pickups. Caution: Make sure to connect magnetic turntable pickup systems only. These inputs are not suitable for connecting high-level audio signal sources like CD-Players, etc.
INPUT/STEREO 16. TONE CONTROL The mixer’s tone control section allows very differentiated and effective shaping of the incoming audio signal within miscellaneous frequency bands. Turning one of the tone controls to the right enhances/amplifies the corresponding frequency range while turning it to the left lowers/attenuates the signal of the specific frequency band. Before altering the sound, all tone controls should be set to their neutral position; i.e. their marker points straight up (detent position).
INPUT/STEREO 21. SIGNAL / PEAK indicator The Signal / Peak indicator provides optical information of a channel’s actual signal level at all times. As already mentioned in the chapter “GAIN”, the “signal present” LED should blink in the rhythm of the incoming signal. If this is not the case, increasing the input level using the gain control is necessary.
EFFECT 1/2 FX1/FX2 The MP7 employs two completely independent 18-bit stereo effect units - FX1 and FX2. The setting of the mono input channels’ individual FX-controls determines the audio signal that is fed to these two units. Identically configured, each unit provides 99 stereo program presets, which can be selected through the use of the UP/DOWN buttons. The 99 preset programs are sorted by algorithm and effect type into different groups, as indicated on a printed label.
EFFECT 1/2 26. PEAK LED These indicators signal if the input stages of the internal FX-units are driven into clipping. To achieve an adequate S/N-ratio, please adjust the FX units’ input level as follows. Note on how to adjust the FX input signal: 1. Establish a “dry” mix - without effect settings - according to the previous descriptions. 2. Set the FX-return control (27) of the corresponding effect channel to its center position. 3. Use the UP/DOWN-buttons to select the desired FX-program preset. 4.
TRANSITIO N / PHONES 28. X/Y LED These LED’s indicate whether an input channel has been assigned to either side of the TRANSITION FADER (29). When these LED’s are dimmed, the transition function has not been activated for either input channel and the TRANSITION FADER is inactive. 29. ASSIGNABLE TRANSITION This assignable fader allows comfortably cross-fading between the audio signals of two selected input channels. Please refer to the paragraph TRANSITION SECTION in the chapter INPUT STEREO. 30.
MASTER 34. MASTER B This control allows setting the output level of the MASTER B, which is a second universal stereo output carrying the stereo-sum audio signal identical to the MASTER A. It is extremely useful in accomplishing sound reinforcement in a neighboring room or monitoring purposes using a second power amplifier. For more details, please refer to the CONFIGURATION EXAMPLES. 35. STEREO/MONO The MASTER B outputs carry a stereo signal if this switch is set to the STEREO position (not engaged).
MASTER 45. STATUS INDICATORS These LED’s provide information about the actual operational status of the MP7’s internal power amplifiers. POWER ON lights whenever the MP7’s power is set to ON. If, after switching the MP7 on, the LED does not light, the first thing to do is to make sure that the mains plug is plugged in correctly. If that is the case and the LED still stays dimmed, please contact your dealer.
MASTER The frequency ranges as well as the characteristics of the EQ-faders are designed to meet your day-in-day-out requirements. In case you intend to have a clear and highly intelligible sound, you might want to increase the level setting of the 8kHz or 16kHz band a bit. If the mid-range sounds a bit nasal, try attenuating the mid-band by some decibels. If you like to provide your sound with more bass, you have to boost the low frequency range, using the 80Hz or the 250Hz controls.
REAR PANEL SPEAKER OUTPUTS RIGHT / LEFT The MP7 provides professional SPEAKON-type high-performance connectors, which offer mechanically and electric secure connection that complies with any safety standards. Additionally, SPEAKON-type connectors allow utilizing highperformance loudspeaker cables with diameters of up to 4 x 2 2.5mm . Single plugs and jacks as well as high-performance speaker cables are available from the DYNACORD accessory assortment.
STANDARD INSTALLATION CABLING The mains cord is supplied with your MP7. The quality of all other cables is left to your responsibility. Carefully chosen high quality cables are the best precaution to prevent problems from occurring during the later operation. In the following we would like to provide you with some recommendations for the trouble-free operation of your setup.
STANDARD INSTALLATION In the following we will explain how to set up a standard PA-system with monitoring facility using the MP7. The equipment list includes: 1 2 2 2 2 2 1 1 MP7 Hi-range speaker system cabinets, e.g. CP 12-2 Bass speaker system cabinets e.g. CP 12-1 Loudspeaker pole-mount stands or 2 intermediate poles Speakon cables, 8m Speakon cables, 2m AM12 active monitor system LF-cable with stereo phone plugs Setting up — Look for the most suitable location to set up the loudspeaker systems.
STANDARD INSTALLATION — Place the needed sound source devices (e.g. CD-Player, turntable) or microphones on a secure even location and, if necessary, establish mains connections — Connect all the gear to the MP7 (Fig. 2). (Fig. 2) — Employ cables with stereo phone-type plugs to connect the AM12 to the MONO OUT of the MP7. Set the LINE IN-control on the AM12 at its center position. This lets you control the AM12’s volume setting from the MONO OUT-control on the MP7.
STANDARD INSTALLATION When operating the MP7 be sure to mind the following notes: 1. A red LED next to the meter instruments that is constantly lit signals that the corresponding channel is on the verge of clipping! Use the Gain-control of the corresponding channel to reduce the audio signal level until the red LED lights only during program peaks. 2. Avoid extreme output levels.
