Aux 1 and Aux 2 AUX SEND 1 and 2 The 1/4" TRS aux sends on the rear panel allow you to send balanced or unbalanced line-level outputs to external effects devices or stage monitors, independent of the main mix. Aux send 1 and aux send 2 are independent of each other, so you can set up two separate aux mixes. The aux 1 send output signal is the sum of all the channels whose aux 1 send control is set to more than minimum. The aux 2 send is the sum of all the channels whose aux 2 send control is set to more than minimum. The overall aux output level can be adjusted with the aux send master controls. AUX SEND 1-2 and FIREWIRE The aux sends are always available as FireWire signals 13 and 14 to send to a computer. For example, you can use your computer with audio production software and effects plugins, as an effects host. This substitutes wonderfully for an outboard hardware effects processor. AUX RETURN 1 and 2 These 1/4" TRS stereo input connectors allow you to add the stereo processed output from external effects processors or other devices to the main mix. Adjust the level of the incoming signals with the aux return master controls. Alternatively, you can use these inputs to add any stereo line-level signals to your main mix, so it could be another line-level source, not just an effects processor. If you are connecting a mono source, use the left (mono) aux return input, and the mono signals will appear on both sides of the main mix. RETURN to AUX 1 The signals going into aux return 2 can also be added to aux send 1 by engaging the return to aux 1 switch. For example, you could add the effects returned from an external effects processor fed by aux send 2, to your stage monitors fed by aux 1. See page 16 for an example of setting up a software effects processor using the aux sends and FireWire. Performance will vary based on system hardware. Aux Sends PRE or POST The aux sends can either be pre channel fader or post channel fader, depending on the position of the pre/post switches in the aux master section. For stage monitor work, use PRE, so the stage monitors do not increase in volume when the channel fader is adjusted. This allows you to set up the monitor mix and levels just right, and not have it change every time a channel level is adjusted. Stage monitors can either be passive speakers powered by an external amplifier, or powered speakers with their own amplifier. For external processors, use POST. In this way, the feed to external processors will vary in level if the channel fader is adjusted. For example, the level of any returned effect (like an echo) will also change if the channel level is changed, keeping them in the same ratio (wet/dry). Aux 1 Aux 2 Modification: Pre-EQ Aux Sends The pre-fader aux sends are post-EQ, so they are affected by the channel EQ controls. The circuit boards can be modified so the pre-fader aux sends are pre-EQ instead of post-EQ. For example, your stage monitors will not be affected by any channel EQ adjustments. This modification can be done by an authorized service center.
