[. . . ] 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. [. . . ] However, the Alt 3-4 bus offers you a second independent stereo submix with its own submaster stereo fader . E. g. : If you want to generate two mono subgroups in addition to the normal main mix stereo bus, patch Alt 3-4 outs back into two mono channels, and use these as Subgroup masters (the subgroup return channels must not be routed to the Alt 3-4 bus themselves, as this would constitute a feedback loop). Channel pan now selects between Alt 3-4 outputs (left = 3, right = 4). + Subgroups can be mixes of several channels of sound: don't be surprised if, once you have set up the input gain correctly, the submaster faders are set higher than "normal" channels. Remember that when Alt 3-4 is in use, you do not have a channel mute facility on your desk: you will have to pull down the fader to silence any channel. 12 4. SETTING UP 5. 1 Selecting inputs 1) Mono channels accept microphone or line inputs. If you are using the microphone input, make sure nothing is connected to the line input (and vice-versa). Never use unbalanced mic cables with the phantom power switched on ever!Any stereo channel can be run in mono simply by connecting into the left connector only. These channels are suitable for a variety of line-level sources including MIDI instruments and tape returns from multitrack. Stereo line inputs are primarily designed for returning effects units, though these too may be given over to multitrack returns or MIDI instrument outputs. + 2) 3) 5. 2 Initializing channels for gain setting 1) 2) 3) 4) 5) Set GAIN to minimum and all aux sends to off (fully counter-clockwise). 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. 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. 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. (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.
