6. Instruccions de funcionament

6.1. Basic Level Setting

1. Set all channel faders and the MAIN MIX fader to their lowest positions.
2. For a microphone channel, speak into the microphone at a normal performance level. Slowly increase the GAIN control until the PEAK LED flashes only occasionally.
3. Gradually raise the channel fader to the "0" position.
4. Slowly raise the MAIN MIX fader until the main level meters show a healthy signal (around 0 dB to +5 dB during peaks).
5. Repeat for other channels.

6.2. Equalization (EQ)

Use the HIGH, MID, and LOW controls on each channel to adjust the tone. Turning a knob clockwise boosts the frequency, while turning it counter-clockwise cuts it. Start with all EQ knobs at the center (flat) position and make subtle adjustments to enhance clarity or correct undesirable frequencies.

6.3. Compression (CH1-CH2)

The one-knob COMP control on channels 1 and 2 applies compression to the input signal. Turn the knob clockwise to increase the amount of compression, which helps to smooth out dynamic peaks and add sustain. Use sparingly to avoid an unnatural sound.

6.4. Seguiment

The MON control on each channel sends a portion of that channel's signal to the MON SEND output. This is useful for creating a separate mix for stage monitors or headphones. Adjust the overall monitor level using the dedicated control (if available, otherwise controlled by individual channel MON sends).

6.5. Tape In/Out

Connect a CD player, MP3 player, or other playback device to the TAPE IN RCA jacks. Use the TAPE TO MAIN MIX button to send this signal to the main output, or TAPE TO MIX 2+PHONES to send it to the Mix 2 and headphone outputs for monitoring or recording without affecting the main mix.

7. Manteniment

• Neteja: Use a soft, dry cloth to clean the mixer's surface. Avoid liquid cleaners or solvents that could damage the finish or internal components.
• Emmagatzematge: Quan no l'utilitzeu, guardeu la batedora en un lloc fresc i sec, allunyat de la llum solar directa i de temperatures extremes.
• Ventilació: Ensure that the mixer's ventilation openings are not obstructed to prevent overheating.
• Gestió de cables: Use proper cable management to prevent strain on connectors and accidental disconnections.

8. Solució De Problemes

• Sense energia: Check the power adapter connection and the wall outlet. Ensure the power switch is ON.
• Sense sortida de so: Verify all cables are securely connected. Check channel faders, MAIN MIX fader, and master volume controls on connected amplifiers/speakers. Ensure input GAIN is set correctly and PEAK LEDs are not constantly lit.
• So distorsionat: Reduce input GAIN if PEAK LEDs are constantly lit. Check for proper impedance matching between sources and inputs.
• Brunzit o soroll: Ensure all cables are in good condition. Check for ground loops; try connecting all audio equipment to the same power strip. Keep audio cables away from power cables.
• El micròfon no funciona: Check microphone cable. If using a condenser mic, ensure +48V PHANTOM power is engaged. Verify GAIN and channel fader are up.
