[. . . ] Depressing on the rear panel will lower the level at the XLR connectors by 20 dB. 4. 6 Monitoring Though most of you will want to audition the Main Mix most of the time include the Alt 3-4 bus and 2-Track playback . A single volume control sends the level to the headphones and main monitors there are exceptions. These . If you want to audition external sources very often, you could connect a hi-fi pre-amp (or tape out) to your 2-Track input, allowing you to monitor a variety of extra sources such as vinyl, cassette, CD etc. 4. 7 Alt 3-4 output By depressing the Mute button Mix. a channels output will be routed to the Alt 3-4 output instead of the Main . Use to have the Signal Level to the Alt 3-4 outputs (TRS jacks on the back panel) is adjusted by PFL-ed ( and up). Alt 3-4 is likely to bewilder newcomers. Subgroups are commonly used as a mixing aid both live and in the studio, e. g. to combine the outputs from all drum channels onto just 1 or 2 submaster faders. However, the Alt 3-4 bus offers you a second independent stereo submix with its own submaster stereo fader . Combining the Alt 3-4 outputs with the Main Mix may be effected by activating the Alt 3-4 to Mix switch . E. g. : If you want to generate two mono subgroups in addition to the normal Main Mix stereo bus, patch Alt outs 3 and 4 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 outputs 3 and 4 (left = 3, right = 4). Fig. 4. 1: Subgroup as Master + 12 Subgroups can be mixes of several channels of sound: dont be surprised if, once you have set up the input gain correctly, the submaster faders are set higher than normal channels. MAIN SECTION EURORACK MX1604A 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. 5. SETTING UP 5. 1 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) EQs set flat and switched out, trimpots and channel Aux Sends turned fully counter-clockwise 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 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. 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.
