Function Buttons and Knobs

1. Ch1-24 input gain control knob The knob Ch1-24 control the gain level of the channel's input. Note: It is very important to properly set the level of the input gain to minimize noise and avoid overload distortion. When the signal> + 18dB, this Clip LED lights green, indicating the relevant channel signal overload. When the signal> -30dB, this Sig LED lights green, indicating the status of the relevant channel input signal.

2. Control Room Knob This knob controls the overall output level for control room.

3. Phones Knob This knob controls the overall output level for headphones.

4. Route to Main Press the input channel button, then press this button, can quickly route the input channel to main (including CH1-24, AUX1-8 and FX1-2).

5. DC48V Phantom Power button Every microphone input equips with an individual phantom power which is controlled by the 48V phantom power button. It will illuminate when phantom power is activated. Note: Please notice that only the condenser microphone needs phantom power. Please do not supply phantom power to any device which don’t need phantom power otherwise the device may be damaged.

23. Solo Press this button will send its channels or buses to the control room outputs. It will illuminate as has been pressed and enabled.

24. Mute Press this button will mute selected channel and all of its assigned outputs. It will illuminate when the button has been pressed and enabled.

25. Select Button There are 12 select buttons as you can see on the panel. Press this button will route its channel to add DSP setting and assign its output. It will illuminate as has been pressed and enabled. Press ”1-12” button, which means CH1-12 correspondingly, press “13-24” button, which means CH13-24 correspondingly, and press ”Levels” button, which means AUX1-8 and FX1-2 correspondingly. In DCA window, you can select group channels by this button.

26. Volume Fader There are 13 faders on the panel which is used for level adjustment of the corresponding channel, including 12 faders for CH1-24 and 1 for Main.

27. S Clear Press this button to clear the solo function for all of the soloed buses or channels.

28. M Clear Press this button to clear the mute function for all of the muted buses or channels.

29. Stereo Link Press this button to select the Pan function, then rotate Parameter Adjust encode to control signal level from left to right for the selected input or output bus. If you have adjusted a channel pan, please just touch 2 times on the screen and make it back to the centre position. The LCD display shows the setting in real time. If two channels have been linked as stereo pair, the LCD display will automatically change to stereo pan.

22. Link button Input channels, aux buses, can be linked as a stereo pair. It will illuminate if the stereo link button has been pressed and enabled. The stereo pairs are predefined and cannot be changed. They are as follows: Channels 1 - 2 / Channels 3 - 4 / Channels 5 - 6 / Channels 7 - 8 / Channels 9 - 10 Channels 11 - 12 / Channels 13 – 14 / Channels 15 - 16 / Channels 17 - 18 / Channels 19 - 20 Channels 21 - 22 / Channels 23 - 24 / Aux 1 - 2 / Aux 3 - 4 / Aux5 - 6 / Aux7 - 8

A stereo link can be enabled when either channel in the pair is selected by pressing the Link button. When the Link button is illuminated which indicates the Stereo Link function enabled, all DSP setting, solo status and main assignments are passed to the other channel in the pair.

• Link & DCA: After link, the channels can also be grouped to DCA as stereo channel, but not able to cancel

the link in DCA. On the contrary, if the channel has been grouped to DCA, it can not link at all, but its paired channel can link. For example, channel 5 is linked with channel 6, then both channel 5 and 6 can be grouped to DCA. But if channel 5 has been grouped to DCA first, it can not link to channel 6, but channel 6 can link to channel 5.

• Link & Routing: The two linked channels can route as stereo channel, while routed channels can also link

later. Please note that this is a nondestructive passing, the other channel's previous setting will be restored after the Link button is disengaged. For example, when Channel 6 has been selected, then press Stereo Link button, all of Channel 6's setting will be copied onto Channel 5. The Channel 5's own setting will restore after the Link button has been disengaged.
