MASTER AUX SENDS 1-6 These knobs provide overall control over the aux send levels, just before they are delivered to the aux send outputs [19]. These knobs go from off to +15 db when turned all the way up. The aux sends can either be pre or post fader, depending on the position of the aux pre/post switches [56]. This is usually the knob you turn up when the lead singer glares at you, points at his stage monitor, and sticks his thumb up in the air. (It would follow that if the singer stuck his thumb down, you'd turn the knob down, but that never happens.) The aux sends can also be sent to FireWire outputs 9-14 for recording [58]. The levels to FireWire are affected by these send controls and the pre/post switch. 56. PRE/POST 5 +15 6 +15 SOLO SOLO PRE POST 63 CR/PHONES ONLY PRE POST 62 SUBS 1-2 3-4 POWER 64 Aux Master This section includes the aux sends and the aux returns. Aux sends tap signals off the channels, via the aux knobs [35], mix these signals from each channel together, then sends them out the aux send jacks [19] and FireWire outputs 9-14. The aux sends can be prefader or post-fader (both are post-EQ, but see page 46). Post-fader aux sends can be fed to the inputs of an external processor like a reverb or digital delay. From there, the outputs of this external processor are fed back to the mixer's aux return jacks [18]. Then these signals are sent through the aux return level controls [59], and finally delivered to the main mix. So, the original unprocessed "dry" signals go from the channels to the main mix, and the processed "wet" signals go from the aux returns to the main mix, and once mixed together, the dry and wet signals combine to create a glorious sound! The pre/post switches determine whether the aux send signal is tapped from the channels before the channel level controls (pre-fader) or after (post-fader). Having a separate pre/post switch for each aux is a super-useful feature as it allows the use of one effects processor and one stage monitor chain, at the same time. For stage monitor work, use pre, so the stage monitors do not increase in volume when the channel level is adjusted. For external processors, use post. In this way, the feed to external processors will vary with the channel level, keeping them in the same ratio, so that the "wet" signal level follows the "dry" signal level. 57. AUX SENDS SOLO This button allows you to solo an individual aux send. If you are using the aux sends to feed your stage monitors, you may use these buttons to check your monitor mix. Beside each switch is an indicating LED to let you easily spot a soloed aux send. The aux send solo is not affected by the solo mode switch (PFL/AFL) [52], except that in PFL mode only the right meter indicates the signal. The aux send's PFL/AFL status is determined by the pre/post switches [56] next to the aux send masters [55]. Pre-fader aux sends are typically used to provide another mix for stage monitors. In this case, the aux returns aren't used to return the signal. Instead, they can be used as additional stereo inputs, or not used at all. 22 Onyx 1640i
