[. . . ] MX1604A Users Manual Version 1. 2 January 2001 EURORACK ® www. behringer. com ENGLISH EURORACK MX1604A SAFETY INSTRUCTIONS CAUTION: To reduce the risk of electrical shock, do not remove the cover (or back). No user serviceable parts inside; refer servicing to qualified personnel. WARNING: To reduce the risk of fire or electrical shock, do not expose this appliance to rain or moisture. This symbol, wherever it appears, alerts you to the presence of uninsulated dangerous voltage inside the enclosure - voltage that may be sufficient to constitute a risk of shock. This symbol, wherever it appears, alerts you to important operating and maintenance instructions in the accompanying literature. [. . . ] Many controls have a natural initial setting. For EQ cut and boost this is centre position. However, some settings, such as selecting pre or post for channel Aux Sends, will depend on the operating environment (e. g. studio or live), or on a particular engineers preferred way of working. 5. 2 Selecting inputs 1) Mono channels accept Mic or line inputs. If you are using the Mic input, make sure nothing is connected to the Line input (and vice-versa). + The Mic inputs are more sensitive than the Line inputs. Do not connect mics with Phantom Power switched on. Never use unbalanced mic cables with the Phantom Power switched on ever!!!Shorting 48 V to earth can cause serious damage. 2) Stereo channels accept -10 dBV or +4 dBu Line level signals. Any stereo channel can be run in mono simply by connecting into the left jack socket only. These channels are suitable for a variety of line-level sources including MIDI instruments and Tape Returns from multitrack. 3) Stereo Line inputs are primarily designed for returning effects units, though these too may be given over to multitrack returns or MIDI instrument outputs. 5. 3 Initializing channels for gain setting 1) Set Gain to minimum and all Aux Sends to off (fully counter-clockwise). 2) Set EQ to flat (all knobs at 12 oclock). 3) Where applicable, set Lo Cut switch frequency content. 4) Set channel mode to PFL 5) Depress Solo/PFL . ON for most mics, OFF for signals with desired very low 5. 4 Auditioning a signal and setting up a channel 1) Provide an input signal i. e. There should also be some activity at the main L/R bargraph meters , indicating the PFL level. 2) For Mic/Line inputs: Adjust the Gain control Continuous signals should not exceed 0 dB. until transient peaks are regularly hitting +6 dB. 3) For stereo Line inputs: Adjust the sources output Gain until transients are regularly hitting +6 dB. Continuous signals should not exceed 0 dB. 5) If an insert is used to patch in a compressor, gate, EQ etc. , use the outboard processors bypass or effect off switch to A/B monitor the effect. If it does not have a bypass switch or equivalent, you will have to keep connecting and disconnecting the device until you complete the following procedure: Adjust the processors output level so that effected and bypassed signals are of comparable level, i. e. SETTING UP 13 EURORACK MX1604A 5. 5 Multitrack initialization Set up the multitrack so that any track in record ready condition has its input monitored when the tape is stationary. [. . . ] This also applies to defects caused by normal wear and tear, in particular, of faders, potentiometers, keys/buttons and similar parts.
