Product Usage Instructions

MIC-XLR / LINE-JACK combo input (ch. 1 / 2)

This is a female MIC-XLR / LINE-JACK combo connector that accepts a balanced microphone XLR input from almost any type of microphone, or a balanced or unbalanced line-level JACK input signal from almost any line source.

The MIC-XLR input is wired as follows:

• Pin 1 = shield or ground
• Pin 2 = + positive or hot
• Pin 3 = – negative or cold

The LINE-JACK input is wired as follows:

• Tip = + positive or hot
• Ring = – negative or cold
• Sleeve = shield or ground

When connecting an unbalanced signal, wire them as follows:

• Pin2 / Tip = + positive or hot
• Pin 1-3 / Sleeve = shield or ground

LO CUT switch (ch. 1 / 2)

This switch cuts bass frequencies below 75 Hz at a rate of 18 dB per octave. It is recommended to use the LO CUT filter on every microphone application except kick drum, bass guitar, bassy synth patches, or recordings. The LO CUT filter helps to make the low frequencies crisper and tastier, reduce feedback in live situations, and conserve amplifier power. It can also be used in combination with the LOW EQ on vocals during live performances to benefit voices without boosting unwanted rumble, mic handling clunks, and breath pops.

CHANNEL GAIN control (ch. 1 / 2)

The gain control adjusts the input sensitivity of the mic and line inputs. This allows the signal from mics and instruments to be adjusted to optimal internal levels. If the signals are plugged into the XLR input, there is a 0 dB of gain with the knob turned down, rising to 40 dB of gain fully up. When connected to the jack input of any channel, there is 20 dB of attenuation down and 20 dB of gain fully up.

INSTRUCTIONS

1. MIC-XLR / LINE-JACK combo input (ch. 1 / 2)

   • This is a female MIC-XLR / LINE-JACK combo connector that accepts a balanced microphone XLR input from almost any type of microphone, or a balanced or unbalanced line-level JACK input signal from almost any line source.
   • The MIC-XLR input is wired as follows:
   • Pin 1 = shield or ground
   • Pin 2 = + positive or “hot”
   • Pin 3 = – negative or “cold”
   • The LINE-JACK input is wired as follows:
   • Tip = + positive or “hot”
   • Ring = – negative or “cold”
   • Sleeve = shield or ground
   • When connecting an unbalanced signal, wire them as follows:
   • Pin2 / Tip = + positive or “hot”
   • Pin 1-3 / Sleeve = shield or ground

2. LO CUT switch (ch. 1 / 2)

   • This switch cuts bass frequencies below 75 Hz at a rate of 18 dB per octave. We recommend that you use the LO CUT filter on every microphone application except kick drum, bass guitar, bassy synth patches or recordings. These aside, there isn’t much down there that you want to hear and filtering it out makes the low stuff you do want much more crisp and tasty. Not only that, but the LO CUT filter can help reduce the possibility of feedbacks in live situations and it helps to conserve the amplifier power. Another way to use the LO CUT filter is in combination with the LOW EQ on vocals during live performances. Many times, bass shelving EQ can really benefit voices.
   • Trouble is, adding LOW EQ also boosts stage rumble, mic handling clunks, and breath pops.

3. CHANNEL GAIN control (ch. 1 / 2)

   • The gain control adjusts the input sensitivity of the mic and line inputs. This allows the signal from mics and instruments to be adjusted to optimal internal levels. If the signals are plugged into the XLR input there is a 0 dB of gain with the knob turned all way down, rising to 40 dB of gain fully up. When connected to the jack input of any channel, there is 20 dB of attenuation all the way down and 20 dB of gain fully up.

4. EQ section HIGH control (ch. 1 / 2)

   • This control gives you up to 15dB boost or cuts at 12KHz with a “SHELVING” curve shape. Use it to increase or reduce the sound “clarity” or “brightness”.

5. EQ section LOW control (ch. 1 / 2)

   • This control gives you up to 15dB boost or cut at 80Hz with a “SHELVING” curve shape. Use it to increase or reduce the sound “punch”.

6. FX send control (ch. 1 / 2)

   • This control sends the signal to the internal Digital Effect Processor. This signal is post-fader, or in other words, it depends on the position of the channel’s FADER.

7. PEAK detector (ch. 1 / 2)

   • The PEAK LED indicates that the input signal is near the CLIPPING point.
   • IMPORTANT: if the LED PEAK flashes reduce the level of the input signal using the GAIN control.

8. FADER LEVEL control (ch. 1 / 2)

   • It adjusts the level of the channel signal and sends it to the MAIN MIX outputs.

9. LINE LEFT/MONO jack input (ch. 3-4 / 5-6)

   • This is a female JACK connector that accepts a balanced or unbalanced line-level input signal from almost any line source.
   • If the RIGHT jack is not inserted, this channel operates like a MONO channel with this input as a single signal source.
   • Wiring is the following:
   • Tip = + positive or “hot”
   • Sleeve = shield or ground

10. LINE RIGHT jack input (ch. 3-4 / 5-6)

    • This is a JACK connector that accepts a balanced or unbalanced line-level input signal from almost any line source. This is used only in the presence of LEFT jack input to use the channel as STEREO.

11. CHANNEL LEVEL control (ch. 3-4 / 5-6)

    • It adjusts the level of the channel signal and sends it to the MAIN MIX outputs.

12. FX LEVEL control

    • It adjusts the level of the internal effect signal sent to the MAIN MIX outputs.

13. FX PRESETS selector

    • The internal Digital Effect Processor is built around a powerful 24-bit DSP. It includes 16 different presets of the studio-grade effect algorithm.
    • HOW TO USE THE FX:
    • rotate the SELECTOR knob to choose the type of effect (preset) you want to use;
    • send the signal to the effect with the FX control (6) of the channel you want to add the effect to;
    • rotate the FX LEVEL (12) knob until you hear the effect added to the original signal;
    • adjust the FX controls (6) just before the signal input clipping indicated by the peak LED (15);
    • re-adjust the FX LEVEL (12) knob to combine the wet-affected signal with the natural dry signal.
    • PRESET DESCRIPTION:
    • p 1. LARGE HALL – This type of reverb simulates the ambiance of a grand concert hall. Dense, smooth reverb with long pre-delay and a lot of high-frequency reflections. Works well with vocals, electric and acoustic guitars, and strings.
    • p 2. SMALL HALL – This type of reverb simulates the ambiance of a small concert hall. Dense, smooth reverb with short pre-delay and a few high-frequency reflections. Works well with vocals, guitars, and woodwinds.
    • p 3. LARGE ROOM – This type of reverb reproduces the more intimate ambiance of natural room acoustics.
    • Feature a lot of early reflections with a lot of high frequency. Works well with vocals, woodwinds, strings, and drums.
    • p 4. SMALL ROOM – This type of reverb reproduces the more intimate ambiance of natural room acoustics.
    • Feature a lot of early reflections with a few of high frequency. Works well with vocals, fingered guitars, and drums.
    • p 5. VOCAL 1 – Amazing reverb designed for vocals with a long tail.
    • p 6. VOCAL 2 – Amazing reverb designed for vocals with a dense tail.
    • p 7. VOCAL 3 – Amazing reverb designed for vocals with a short tail.
    • p 8. PLATE 1 – This is a simulation of classic ’70s and ’80s metal plate reverb with a long tail.
    • p 9. PLATE 2 – This is a simulation of classic ’70s and ’80s metal plate reverb with a short tail.
    • p 10. STEREO DELAY 1 – Echo effect with a ping-pong of left and right channels with long delay times.
    • p 11. STEREO DELAY 2 – Echo effect with a ping-pong of left and right channels with short delay times.
    • p 12. HALL + DELAY – Preset 1 and 10 combined.
    • p 13. ROOM + DELAY – Preset 3 and 11 combined.
    • p 14. VOCAL + DELAY 1 – Preset 5 and 10 combined.
    • p 15. VOCAL + DELAY 2 – Preset 5 and 11 combined.
    • p 16. REVERB + CHORUS – Typical reverb and modulation effect combined, the chorus effect provides a soft, ethereal sweeping effect. Perfect for enhancement of electric and acoustic guitar and bass.
    • Also adds a dramatic effect to vocals, particularly group harmonies, and choirs.

14. EFFECT MUTE button

    • Engage this switch if you want to mute the signal outgoing from the internal effect to the MAIN MIX.

15. EFFECT PEAK/MUTE detector

    • This LED shows 2 conditions:
    • always lighted = signals that the effect is MUTED.
    • flashing = signals a too high input level, near to the overload of the effect input stage, that can cause audible distortion. In this case, reduce the level of the FX sends.

16. MAIN MIX LEVEL control

    • The MAIN MIX controls the output level just before the MAIN MIX outputs and HEADPHONE output. When the potentiometer is fully down the MAIN MIX is off, while the “0” indicates a +4dBu nominal output level.
      Typically, this control is set near the “0” label and left alone, but it can be used for song fadeouts or quick system-wide mutes.

17. PHONES LEVEL control

    • This controls the PHONES output’s level.

18. L & R LEVEL meters

    • The level meters are made of two columns of four LEDs with three colors to indicate different ranges of signal levels:
    • green = shows the normal operative level of the signal (from -20 to 0 dB peak)
    • yellow = shows the nominal operative level of the signal (from 0 to +6 dB peak)
    • red = shows a high signal level (near +20 dB peak CLIP level).

19. +48V phantom switch and LED

    • This switch activates (LED on) and deactivates (LED Off) the phantom power on MIC Inputs. Most professional condenser microphones require phantom power, which is a lower DC voltage delivered to the microphone on pin 2 and 3 of the XLR microphone connector. Dynamic microphones do not require phantom power, however, phantom power will not harm most dynamic microphones should you plug one in while the phantom power is on. Check the manual of your microphone to find out for sure whether or not phantom power can damage it.

20. ON LED

    • Indicates when the mixer is switched on.

21. MAIN MIX L & R XLR output (balanced)

    • These XLRs provide a balanced line-level signal that represents the fully mixed stereo signal controlled by the MAIN MIX fader. Connect these to the inputs of your power amplifier, powered speaker or other audio processors.
    • NOTE: whenever possible, use always balanced cables. Unbalanced lines may also be used but they may result in noise over long cable runs. In any case, avoid using a balanced cable for one channel and an unbalanced one for the other.

22. MAIN MIX L & R jack output (balanced)

    • These jack connectors are connected in parallel to the respective XLR outputs.

23. PHONES stereo jack output

    • STEREO JACK connector for the headphones output: only stereo headphones with a minimum impedance of Ohms should be connected to this output. The signal is always the same as the MAIN MIX outputs.

24. 18V~ supply socket input

    • Here’s where you plug in your mixer’s external power supply. You should always connect your power supply to the mixer before you plug the power supply into an electrical outlet.

25. POWER switch

    • Switch this one on and your mixer has power. Switch it off and it doesn’t. Make sure that all master output knobs are turned down when powering your mixer up or down.

26. Power cable hook

    • Use this hook to prevent power cable drawing: simply go through it before connecting the cable to the 18V~ socket.
