Frequently Asked Questions - 172.567 Skytec

How do I connect a microphone to this mixing console?

Use a balanced mono input (XLR). Ensure phantom power is off if your microphone does not require it. Connect the microphone, then adjust the TRIM to set the input level.

What should I do if the clipping (PEAK) LED lights up?

The red LED indicates the signal is approaching the clipping threshold. Reduce the channel gain (TRIM) or the fader to avoid distortion and protect the speakers.

How do I use the 48V phantom power?

Press the switch (35) to activate phantom power on all balanced mic inputs. Do not use with dynamic microphones or unbalanced devices, as this could damage them.

Can I use unbalanced cables on the balanced inputs?

Yes, line inputs accept both balanced and unbalanced signals. For a balanced mic input, it is better to use a balanced cable to reduce interference. Avoid phantom power with unbalanced cables.

How do I clean the mixing console?

Do not use sprays to clean the potentiometers, as residue attracts dust. In case of problems, consult a specialist. For the exterior, use a dry, soft cloth.

What should I do during a thunderstorm?

Disconnect the mixing console from the mains to avoid damage from lightning. Do not plug in the device if condensation has formed; wait until it reaches room temperature.

How do I adjust the equalizer to avoid damaging the speakers?

Always start with all equalizer knobs at 0. Adjust frequencies once the music is playing. Avoid sudden changes that could cause clipping.

How do I use the AUX sends (AUX Send)?

AUX 1 is pre-fader (independent of channel volume), ideal for a monitor mix. AUX 2 is post-fader, used to send the signal to effects. Adjust the level with the corresponding potentiometer.

How do I pre-listen to a channel using the PFL function?

Press the PFL button on the desired channel. The signal from that channel will be audible in the headphones, regardless of the master fader. This allows you to check the level before sending it to the main mix.

What are the essential safety instructions?

Read the manual before use. Never open the housing (live parts inside). Use a grounded 230V/50Hz/10-16A outlet. Disconnect during a thunderstorm. Turn on the amplifier last and turn it off first. Keep out of reach of children.

MONO INPUT CHANNELS

1. BALANCED INPUT

Electronically balanced input for standard XLR connectors. Features a 48V phantom power (to be switched on via (35))

2. LINE INPUT

This unbalanced input accepts balanced and unbalanced microphones, turntables, keyboard, etc.

3. LOW CUT

This push button improves the use of the microphone. When the low cut function is activated you have fewer problems with noise, interference and pop noises.

4. TRIM

This function allows you to set the input sensitivity of each channel to the constant level of the input signal.

5. HIGH

Sets the high frequencies on each channel. Leave this knob in the "0" position first. Set the signal once the music has started to play in order not to damage the speakers. Turn cw to increase the higher frequencies and ccw to reduce them.

6. FREQUENCY & MID

This equalization function has a "bell" reaction with a fixed Q fader of 1.5. The frequency can be set between 100 & 8000 Hz and the volume between -15 & +15 dB.

7. LOW

This knob sets the low frequency range of each channel. Leave this knob in the "0" position first. Set the signal once the music has started to play in order not to damage the speakers. Turn cw to increase the lower frequencies and ccw to reduce them

MIC 1 LINE 1 BAL OR UNBAL 2 3 LOW CUT /75 Hz -10 +4 TRIM

5 HIGH -15 +15 0 6 MID -15 +15 1.1 5 FREQ -25 6 7 -15 +15 LOW

8. AUX 1

This AUX send control is pre-fade, post-EQ. Therefore the signal is not controlled by the position of the fader and the routing status of the channel. This send function is very convenient to cross monitor signals that have to be controlled separately from the PA installation.

9. AUX 2

This AUX send control is post-fade, post-EQ. Therefore the signal is sensitive to changes in the fader position. It is normally used to feed an audio signal to an effect unit. As the signals are always sent back into the mixer, the fader must be able to control these signals.

10. PAN

The PAN control feeds continuously variable quantities of the post-fader signal to the left or right and G1 or G2 main busses. In the centre position / "∞" the same signal is sent to the left and right and the G1 and G2 main busses.

11. PEAK

A red LED lights up when the peak signal reaches the maximum value that the mixer can handle. If this lasts over a longer period of time, you might damage the unit. The LED lights up at a volume level of 5 dB below clipping.

12. PFL

If this button is pressed, you can monitor the signal via headphones. This applies only to channels where the PFL function is switched on. All other channel can then not be monitored through the headphones

13. STEREO

When this button is pressed, you can use the L-R master faders to allocate a stereo position to the signal of this channel over the output signal.

14. GRPS 1-2

When this button is pressed, you can use the G1-2 master fader. Now, the signal is bundled with all other channels on which this function is activated. The L-R master faders are inactive now.

15. CHANNEL FADER

This slider control sets the volume of that channel. Set it to the "0" position when you connect a signal. Push the slider control upwards until the required output volume is reached. Please note, you can further change the volume of this channel via one of the master faders.

STEREO INPUT CHANNELS

16. LEFT (MONO) / RIGHT

6.3 mm jack input for connection of a Line signal. If L+R are both connected, this channel is stereo. If only the left input is connected, a mono signal is fed to the left and the right bus (the signal is simply spread over the left and the right bus). If you connect only the right input, the signal is fed only to the right bus.

17. HIGH

This knob controls the high frequencies per channel. Set this button always in the "0" position first. Control the signal once the music has started playing in order to prevent damage to the speakers. Turn cw to increase the high frequencies and ccw to reduce them.

18. HI MID & LO MID

This knob controls the medium range frequencies per channel. Set this button always in the "0" position first. Control the signal once the music has started playing in order to prevent damage to the speakers. Turn cw to increase the medium frequencies and ccw to reduce them.

19. LOW

This knob controls the low frequencies per channel. Set this button always in the "0" position first. Control the signal once the music has started playing in order to prevent damage to the speakers. Turn cw to increase the low frequencies and ccw to reduce them.

20. AUX 1

This AUX send control is pre-fade, post-EQ. Therefore the signal is not influenced by the position of the fader and the routing status of the channel. This send function is very convenient to cross monitor signals that have to be controlled separately from the PA installation.

21. AUX 2

This AUX send control is post-fade, post-EQ. Therefore the signal is sensitive to changes in the fader position. It is normally used to feed an audio signal to an effect unit. As the signals are always send back into the mixer, the fader must be able to control these signals.

22. BAL

The BAL control feeds continuously variable quantities of the post-fader signal to the left or right and G1 or G2 main busses. In the centre position "∞" the same signal is sent to the left and right and the G1 and G2 main busses.

23. PFL

If this button is pressed, you can monitor the signal via headphones. This applies only to channels where the PFL function is switched on. All other channel can then not be listened to through the headphones

24. STEREO
