CONNECTORS, CONTROLS AND FUNCTIONS

1. [MIC/LINE] combo input: This input accepts balanced XLR connectors for microphones as well as unbalanced Jack connectors for LINE signals
2. [LINE R] jack input: when you want to use this channel for a stereo line signal, you can plug the jack of the left channel in the combo input (1) and plug the jack of the right channel in this LINE R input, located just below the combo input.
3. PHANTOM Power switch: This switch toggles the phantom power on or off. Set this switch on when using one or more condenser microphones that need to receive external power from the mixer.
   When this switch is on, the mixer supplies DC +48V power to pins 2 and 3 of the XLR-type MIC INPUTS. All the mono channels have an individual phantom power switch, except for channels 7/8 and 9/10 where the switch activates the phantom power on the combo inputs of both channels.
   • Be sure to leave this switch off if you do not need phantom power
   • When tuning the switch on , be sure that only condenser MICs are connected to the XLR input
   WARNING: Devices other than condenser MICs may be damaged if connected to the phantom power supply. However, the switch may be left on without problem when connecting balanced dynamic microphones.
   To avoid damage to speakers, be sure to turn off the amplifiers (or powered speakers) before turning this switch on or off. We also recommend that you turn all out controls (MAIN master fader, AUX send, etc.) to minimum settings before operating the switch, to avoid risk of loud noises that could cause hearing loss or device damage.
4. [LOW CUT] filter button: this button can be used to cut frequencies below 80Hz. This can be useful to decrease popping of microphones or to avoid low feedback from acoustic instruments. If you use subwoofers, activating this filter removes the input source from the subwoofers. It helps to create a cleaner mix.
5. [GAIN] control knob: According to the level of the input signal, use this knob to adjust the input signal to an appropriate level. The level status can be checked by using the PFL button and the VU-meters:
   • Switch off the pfl buttons (16) on all channels
   • Now only switch ON the PFL button (16) of the channel you want to check
   • Play the music or instrument at the level you will always do during the performance.
   • Check the level on the VU-meter and adjust the gain knob (5) till you reach the desired input level.
   This setting is very important: if the level is too low, you might not be able to reach a sound level that is high enough on your outputs and you will generate extra unwanted noise. If the level is too high you will generate distortion that will result in a very bad sound, it can even destroy your speakers !
   That’s why we have also added some [PEAK] LED’s (13). The LED’s can flash from time to time, what means the level is OK. If you see the LED is ON for longer periods, it means you have to turn down the GAIN level for this channel !
6. [HIGH]: This knob adjusts the channel’s high frequency band. Setting the knob to the “0” position produces a flat frequency response .Turning the knob to the right boosts the corresponding frequency band ,while turning to the left cuts the band.
7. [MID]: This knob adjusts the level of the channel’s medium frequency band. Setting the knob to the “0” position produces a flat frequency response .Turning the knob to the right boosts the corresponding frequency band ,while turning to the left cuts the band.
8. [LOW]: This knob adjusts the channel’s low frequency band. Setting the knob to the “0” position produces a flat frequency response .Turning the knob to the right boosts the corresponding frequency band ,while turning to the left cuts the band.
9. [AUX1] knob: This knob controls the level of your channel signal that is sent to the AUX3 output (25). This signal is Pre-Fader, what means the level is not influenced by the position of the channel fader. It is mainly used to send an audio signal to stage monitors
10. [AUX2] knob: This knob controls the level of your channel signal that is sent to the AUX3 output (25). This signal is Pre-Fader, what means the level is not influenced by the position of the channel fader. It is mainly used to send an audio signal to stage monitors
11. [AUX3/FX SEND] knob: This knob controls the level of your channel signal that is sent to the internal effect module and/or to the AUX3 output (26), for example to run an external effect engine. This signal is Post-Fader, what means the level is influenced by the position of the channel fader.
12. [PAN] knob: This control pans the channel signal across the MAIN L/R and the G1/2 group busses, thus determining the perceived position of the sound from that channel in the output stereo sound field. If a PAN control is set all the way to the left, for example, the sound from that channel will be heard from the left speaker system only. If it is set all the way to the right, the sound will be heard from the right speaker system only. Intermediate settings will cause the sound to appear at corresponding locations in the stereo sound field
13. [PEAK] LED indicator: This LED indicator shows the level of the signal input of the channel. The peak indicator lights up when the input signal reaches 5dB below the channel’s clipping point. This indicator shows the level of the Post-EQ/ pre-fader signal. If the PEAK indicator lights more than briefly on high- level transients, you should use the red GAIN control knob to decrease the input sensitivity of the channel. If this does not work, reduce the output level of the connected source.
14. [MUTE] knob: With this knob you can quickly mute the channel output without that you have the modify the position of the channel fader.
15. [PFL] knob: Press this knob to activate the PFL mode for this channel (pré-fader-listening). The sound of only this or these channels that have the mode switched on will be sent to the headphones output (22), so you can listen to a specific channel or instrument of your mix. The knob can also be used to set precisely the level of the input GAIN (5). (Check the description of the [GAIN] button 5. above for more information)
16. [MAIN] knob: Select this function if you want to send the audio signal of this channel to the [MAIN] busses.
17. [G1/G2] knob: Select this function if you want to send the audio signal of this channel to the [G1/G2] group busses. They can be used to send the audio signal to a separate sound system, subwoofers, or can be used as a real subgroup so you have control over a specific group of channels. The level of this group will be controlled by the [G1/G2] fader (43). The signal can then be reinjected to the [MAIN] output. Subgroups make it easier to mix complex setups. You can for example make a mix of all the  backing vocals. Send this mix to the [G1/G2] busses, then reinject the group into the [MAIN] output by using the [TO MAIN] switch (41). You can now control the level of your backing vocals with the [G1/G2] fader (43) without that you have to move every separate backing vocal fader (and keep the correct balance)
18. Channel Fader: This is the channel’s main level control. It determines the level of the signal that is sent from the channel to the master mixing and post fader effect busses (AUX3 and internal effect module). It is the settings of the input channel faders that determine the mix, or the balance of sound levels between the instruments or other sources connected to the inputs. When a channel is not being used, its fader should be set at the minimum position to prevent the addition of unwanted noise to the main  program signal. You can also mute the channel with the [MUTE] knob (15)
19. [CH9/10 or USB] switch: with this switch you can select the audio source for channels 9/10
    • = signal from the input connectors (1 & 2) of channel 9/10
    • = signal from the internal player (29): USB Stick (30) / computer (30) / Bluetooth receiver
20. [TAPE] input: extra unbalanced line input. The level can be set with the [CD/TAPE] button (39).
21. [REC] output: unbalanced line output that can be used for analogue recordings.
22. [PHONES] output: connect your headphones here. The output level can be controlled with the [PHONES] knob (38)
23. [MAIN OUT]: Use the balanced XLR-connectors to connect this mixer to any amplifier or active speakers.
24. [RETURN] input: When you use an external effect generator or other gear, you can send the signal to that unit by using the [AUX3] (26) output. The processed signal can be reinjected in the mixer via this [RETURN] input. If this function is not used, you can also use this input to send an extra audio source into the mix. Its level can be controlled via the RETURN knob (40)
25. [AUX1, AUX2] output: these outputs are mainly used to run stage monitors. The signal is pre-fader, meaning it is not influenced by the position of the channel faders. The general level for this output can be controlled by the individual AUX buttons (37)
26. [AUX3] output: this output is mainly used to run an external effect processor. The signal is post-fader, meaning it is also influenced by the position of the channel faders. The general level for this output can be controlled by the individual AUX3 button (37)
27. [G1 & G2] outputs: when the G1/G2 switches are activated on some channels, the audio signal of these channels will be sent to these G1 and G2 outputs. The position of the [PAN] button (12) of each channel has an influence on these individual audio signals: When a [PAN] button is set totally to the left, the audio signal will only be sent to G1. When it’s set totally to the right, it will only be sent to G2. When the [PAN] button is set in the middle position, the audio signal will be sent to G1 and G2
28. DISPLAY: shows you all the information about the status of the internal player and the effect program that has been selected.
