24. AUX 1 (Monitor) Control This control allows the user to send the corresponding signal to the AUX 1 output, which can be used in conjunction with an amplifier and studio or stage monitors, or simply as an auxiliary output for any means required. The control is pre-fader, therefore any changes made to the corresponding channel level control do not affect the AUX 1 send signal. 25. AUX 2 (Effects) Control This control alters the signal level that is sent to the AUX 2 (or EFX) send output, which can be used in conjunction with external signal processors (this signal of which can be returned to mixer via the AUX return input, or any stereo input channel), or simply as an auxiliary output for any means required. This control is postfader, therefore any changes made to the corresponding channel level control are also applied to the EFX signal. The EFX send signal is also sent to the built-in effect processor for providing effects to the main output and AUX 1 send, as required. 26. Pan / Balance Controls This alternates the degree or level of audio that the left and right side of the main mix should receive. On mono channels, this control will adjust the level that the left and right should receive (pan), where as on a stereo channel, adjusting the BAL control will attenuate the left or right audio signals accordingly (balance). 27. Mute / ALT 3-4 This handy little button is basically a typical mute button � effectively stopping any signal received by the channel from being sent to the Main L/R or AUX 2 send mixing buses � however it does so much more. Pushing this button routes the

29. Level Control This rotary control will alter the signal level that is sent from the corresponding channel to the Main or Alt. 3- mixing bus. 30. +4 / -10 Switch This button, located on both stereo input channels, is used

adjust the input sensitivity of the corresponding channels, which will adapt the mixer to external devices which may

use different operating levels. If the input source is -10 dBV (consumer audio

level), it is best to engage the switch, allowing the signal to be heard. The +4 dBu level is suitable for Professional Audio signals, which are considerably higher than the consumer level. However, if you are unsure of the source�s operating level, we suggest leaving the switch disengaged until you test the source�s signal. You can then engage if necessary (if the level of the input signal is obviously too low).

channel�s signal away from the Main L/R and to its own �Alternate� stereo output (Alt 3-), where the signal can be used at will. If you wish to use it to connect an amplifier and speakers, or simply patch it through to an unused input channel, you can easily do so. 28. Peak Indicator This LED indicator will illuminate when the device hits high peaks, 6 dB before overload occurs. It is best to adjust the gain of the channel so that the PEAK indicator lights up on intervals only. This will ensure a greater dynamic range of audio. This LED will light up while the Mute button is pushed in. HELIX BOARD 12 FIREWIRE MKII

31. Digital Effect Display This 2-digital numeric display shows the program number that is currently applied to your EFX audio signal. When you rotate the Program control, you can scroll through different program numbers; however the display will revert back to the original program if a new program is not selected within a few seconds. For a list of available effects, please observe the Digital Effect Table. 32. Sig and Clip Indicators Located within the Digital Effect Display are Clip and Sig LEDs. The Sig LED will light up when any signal is received by the effect processor, and the Clip LED will light up shortly before excessive signals are dynamically clipped. If the Clip LED lights up too often, it may be advisable to turn down the AUX 2/EFX control on one or all input channels to ensure the signal level is not excessive. 9
