User manual DYNACORD MP7

[. . . ] 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. Do not block any of the ventilation openings. install in accordance with the manufacturers instructions. Servicing is required when the apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped. [. . . ] Once a PFL button is pressed, the master display automatically enters PFL/PGM mode (yellow LED below the display lights). The right LED-chain indicates the level of the master audio signal (PGM), while the left LED-chain indicates the PFL bus signal level. 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. On the other hand, if the PEAK LED lights constantly, the corresponding channel is likely to enter clipping and you have to reduce amplification using the gain control. The "signal present" LED lights at levels 30dB below clipping while the peak LED lights at a level of 8dB below the occurrence of overdrive. To prevent the mixer's input channels from clipping, which for instance may be caused by increasing volumes, keeping an eye on these indicators during operation is a good idea, too. Of course, engaging a channel's PFL-button allows monitoring that channel's level via the display in the master section. Be sure to only engage the PFL-key of the channel that you are about to adjust. The channel's level is displayed in the master display's left LED-chain. Here as well, make sure that the red LED (+12dB) lights only briefly during dynamic peaks. Different from the fader function of the MIC input channels, here, the audio signal is not amplified when a channel fader is set to its maximum position. To be sure to use the mixer's entire dynamic capacity, set the CHANNEL FADER during playback to its maximum position. Each unit provides 99 program presets, which are selected by the use of the UP/DOWN buttons. The 99 presets are divided into groups according to their different effect structure, as shown on a printed listing. The programs within each preset group are sorted in ascending order, where higher numbers provide the same FX type with increased intensity. Presets 1 - 20 offer high quality reverberation effect programs that are equally suitable for live performance, recording studio or home recording applications. Program numbers 21 - 40 provide mixed effect types of echo/reverb and chorus/reverb while the numbers 41 - 60 offer different delay effects. The last group from 61 - 99 provides different flanger, chorus, and doubling effects presets as well as special delay and reverb programs. During the initialization of the FX units (when switching on the power of the PowerMate), preset 05 (Large Hall 3 Bright) is selected for the FX1 while the FX2 unit is set to preset 55 (Delay Mono 250ms). These two effects are similarly suitable for live performances and recording applications. This is the factory-preset configuration that can be changed any time. [. . . ] 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. Employing high-quality, high-performance PA-speaker systems, like the CP12-1 and CP12-2, allows sound reproduction at extreme high sound pressure levels, which bares the risk of resulting hearing damage. the same is true for the headphones output.
