Configuring the Inputs and Outputs

Unless where noted, configurations can be made from the hardware or from the GUI.

Inputs

① Select the Audio Source (GUI only)

• Analog (default): Audio is from a microphone or line-level audio source

connected to a channel input on the mixer back panel.

• Network: Audio is from the Dante digital audio network. Go to the Inputs

tab of the GUI to select Network audio for each desired channel. Dante

Controller software is required to properly route audio to the channel

inputs.

② Select the Input Gain

Select the analog input gain for each channel. No gain is applied for

analog line-level or when the audio source is set to Network.

• Mic (+46dB): For less sensitive microphones, such as dynamics.

• Mic (+26dB): For loud talkers or sensitive microphones such as

condensers.

• Line (+0dB): For line-level sources such as mixer inserts.

③ Supply Phantom Power

Supply 48 V phantom power to the channel when using condenser

microphones. (Phantom power is disabled when Input gain is set to Line.)

④ Adjust Channel EQ

Adjust the high- and low-frequency equalization to improve intelligibility

and reduce undesired noise:

• Low Cut: Ideal for attenuating low-frequency vibration caused by table

vibrations or air-conditioning rumble. Adjust the frequency of the 12 dB/

octave filter from 25 - 320 Hz.

• High Shelf: For tempering sibilant speech or enhancing the sound of off-

axis microphones. Use this to boost or cut the signal by 12 dB at 5 kHz

with a slop of 12dB/octave.

Direct and Mix Outputs

⑤ Assign the Direct Outputs (GUI Only)

Assign the Direct Output for each channel from the Output tab of the

GUI.

• Pre-EQ: After the Input Gain

• Post-EQ: After the EQ blocks

• Post-Fader: After the channel fader

• IntelliMix: After the IntelliMix gating decision

• IntelliMix NOMA: After IntelliMix gating and NOMA decisions

⑥ Set Mix Output Level (GUI Only)

Set the Output level according to the input of the connecting equipment:

• Line (-0) (default): No attenuation to the output level.

• Aux (-20): The signal is attenuated 20 dB to avoid clipping a line input.

• Mic (-46): The signal is attenuated 46 dB to match a microphone input.

⑦ Set the Limiter

The output limiter prevents distortion during loud program peaks without

affecting normal program levels. This prevents overloading the devices

connected to the mixer outputs.

⑧ Adjust the Output Gain

Adjust the overall output level of the mix.

Auxiliary (Aux) Input

The SCM820 features two auxiliary inputs: an 1/8” jack on the front panel

and a back panel input (block connector or RCA connectors, depending

on the model). Each input sums the left and right channel to a mono

signal. This mono signal is routed directly to the mix outputs, bypassing

the automixing process. Use this input for sources such as an MP3

player or computer speaker output.

Digital Channels

When the mixer is connected to a Dante network, the left and right

channels are accessible before they sum to the mono signal for the mix

outputs. Use the Aux L and Aux R channels in Dante Controller to route

audio to and from the aux channel.
