This encoder controls the mix of the input signal into the main output from full level to off.

3. Direct Monitor Output Switch & Indicators

Turns direct monitoring on or off and allows you to send the direct monitor signal to either the Main output or the S/PDIF output. The direct monitor signal is a mix of all inputs.

4. Mono Switch (Direct Monitor)

7. Soft Limit LEDs

The Soft Limit LEDs indicate that the signal level is being soft limited. When enabled in the E-MU USB 2.0 Audio Control Panel, the analog soft limiters begin to gently turn down the gain whenever the signal level goes above -12 dBFS. The soft limiters allow you to run a hotter signal without fear of clipping.

8. Signal Level & Clip Indicators

The LED signal level indicators show the signal level for both analog inputs. The red clip indicators momentarily remain on whenever your input level exceeds -2.5 dBFS. With a proper signal level, the yellow -3dB LED will come on occasionally, but the red clip LED should never light.

9. Input Level Gain Controls

The preamp level controls set the input gain from 0dB to +65dB. The wide mark indicates the 0dB/unity setting when using unbalanced input cables. The 0dB mark indicates unity gain when using balanced input cables.
