User manual JBSYSTEMS MM 14D V1.0

[. . . ] If a foreign object enters the unit, immediately disconnect the mains power. No naked flame sources, such as lighted candles, should be placed on the appliance. Don't cover any ventilation openings as this may result in overheating. Always unplug the unit when it is not used for a longer time or before you start servicing. [. . . ] It is absolutely necessary for the user to strictly follow the safety instructions and warnings in this user manual. The dealer will not accept responsibility for any resulting defects or problems caused by disregarding this user manual. To protect the environment, please try to recycle the packing material as much as possible. Check the contents: Check that the carton contains the following items: User manual MM-14D unit Power Supply When installed in a booth or flight case, please make sure to have good ventilation to improve heat evacuation of the unit. To avoid condensation to be formed inside, allow the unit to adapt to the surrounding temperatures when bringing it into a warm room after transport. Condense sometimes prevents the unit from working at full performance. CLEANING THE APPLIANCE: Clean by wiping with a polished cloth slightly dipped with water. Do not use volatile liquids such as benzene or thinner which will damage the unit. For more information on connections, please refer to the next chapter. Be sure to turn off the mixer before you make changes to the different connections. INSERT Allows you to insert an external effect (like compressor, noise gate, equaliser, etc) that you will only use for this channel. LOW CUT FILTER Switch When this button is lit, the frequencies below 75Hz for this channel will be filtered. This can be usefull for example to avoid `popping' of microphones or stage rumble. CLIP LED This warning will illuminate 4dB before clipping and will remain on for a short period. For optimal input channel running level, adjust Gain Control until Clip indicator illuminates while signal peaks are present. GAIN CONTROL Allows maximum input signal control and will accommodate most microphones of both low or high impedance to 600 Ohm as well as Phantom Power (48 Volt) types. The line input can be anything from keyboard through to line level feeds from other equipment. When the AUX1/FX send (11) is used, the internal effect unit is switched off. The AUX1 send level changes with the position of the channel fader (17). AUX SEND 2 (Pre-Fade or Post-Fade) This knob is used to send the audio signal of this channel to the AUX 2 SEND output. pRE-FADE / POST-FADE SWITCH for AUX SEND 2 Button is lit: AUX2 for this channel is switched PREFADE. The level is only influenced by the Gain control (7) and not by the channel fader (17). [. . . ] DSP MUTE When this button is lit, the internal effect unit is switched off. FOOT SWITCH connector Here you can connect a foot switch to switch the internal effects on/off. We strongly advise to set the master output faders (9) of the mixer and the gain controls of your amplifier to zero before you switch the mixer on or off. PHANTOM POWER SWITCH This +48Vdc voltage should be used when condenser microphones are connected to the microphone inputs. [. . . ]
