1. MIC

XLR inputs for low impedance balanced microphones.

2. LINE

6.3 mm ( 14 ") inputs for musical instruments or other devices.

3. GAIN

Controls the gain level of the microphones or equipment connected in each channel. The internal scale (-16 to -60 dB) corresponds to the microphones; (+10 to -34 dB) corresponds to musical instruments or other devices.

4. HIGH

Adjusts the sounds between -15 and +15 dB, with a center frequency of 12 kHz.

5. MID

Adjusts the signal of all musical instruments and the human voice between -15 and +15 dB, with a central frequency of 2.5 kHz.

6. LOW

Adjust the signal of the male human voice and guitars or drums between -15 and +15 dB, with a central frequency of 80 Hz.

7. AUX SEND

Send the signal to the AUX bus; Ihe signal is pre-cleared so that the auxiliary sending is independent of the general fading. It is ideal for feedback or monitor.

8. AUX EFFECT

Adjusts the echo effect level for the channel.

9. PAN

Distribute the signal level between the left and right channels to make a stereo sound effect.

11. CHANNEL (for channels 1 - 8)

Adjust the channel volume.

12. PFL (for channels 1 - 8)

If the button corresponding to a channel is activated, it allows monitoring that channel through the output for hearing aids (PHONES). In addition, the other channels are automatically deleted.

13. Balanced outputs

Sends the mixed signal through separate outputs (left / right) of BNC, to connect amplified speakers (baffles) or amplifiers.

14. Unbalanced outputs

Sends the mixed signal by separate outputs (left / right) of 6.3 mm, to connect amplified speakers (baffles) or amplifiers.

15. AUX SEND 1 (jack)

Send the mixed signal through a 6.3 mm output to connect auxiliary amplifiers.

16. PHONES (jack)

Output to monitor, with 6.3 mm connection headphones, the mixed or individual signal of each channel.

17. Level meters

Green LED → Output in optimal condition

Yellow LED → Output in out of range condition

Red LED → Output in exceeded condition

18. PHONE (knob)

Adjusts volume for the headphone output (PHONE).

19. AUX SEND 1 (knob)

Adjusts volume for the auxiliary output (AUX SEND 1).

20. PFL (EFFECT)

If this button is activated, the effect level is selected to send it to the left / right output channels with respect to the activated PFL signals.

21. Master volume control

Adjust the general output level.

22. EFFECT / RETURN volume control

Adjusts the gain level for the echo effect with respect to the signal connected to the RETURN jack.

23. Mp3 player
