[. . . ] MX2004A User's Manual Version 1. 1 March 2001 EURORACK ® www. behringer. com ENGLISH EURORACK MX2004A 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. [. . . ] Set CHANNEL MODE to PFL Depress PFL/SOLO switch . ON for most microphones, OFF for signals with desired 5. 3 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 microphone/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 source's 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 processor's 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 processor's output level so that effected and bypassed signals are of comparable level, i. e. Move onto next channel. 5. 4 Desk normalization All board settings should be set to the normal default condition before or after every session. Usually faders are set to zero (minus infinity) EQ's set flat and switched out, trimpots and channel aux sends turned fully counterclockwise etc. 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 engineer's preferred way of working. 5. SETTING UP 13 EURORACK MX2004A 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. Place all tracks to be recorded into "record ready" status. (Once a recording has been made, these tracks should automatically switch to tape playback. Check that the input levels to each track are optimized before recording commences). 5. 6 Recording levels When recording to digital, it's a good idea to keep the recorder's peak meters below 0 dB. samplers) read 0 dB with some headroom left. This is because, unlike with analog, the onset of digital distortion is as sudden as it is horrible. If you really want to take your recording level to the limit (and fully exploit for instance 16-bit digital's 96 dB dynamic range), you'll have to do some calibrating. Well, you could run a tone at 0 dB from the mixer and use that as your DAT reference. [. . . ] This also applies to defects caused by normal wear and tear, in particular, of faders, potentiometers, keys/buttons and similar parts. Damages/defects caused by the following conditions are not covered by this warranty: s misuse, neglect or failure to operate the unit in compliance with the instructions given in BEHRINGER user or service manuals. s connection or operation of the unit in any way that does not comply with the technical or safety regulations applicable in the country where the product is used. s damages/defects caused by force majeure or any other condition that is beyond the control of BEHRINGER.
