5. Miksera darbība

This section provides guidance on operating your Behringer UB802 mixer.

1. Ieslēgšanas secība: Turn on your mixer first, then your amplifier or powered speakers. When powering off, reverse the sequence (amplifier off first, then mixer) to prevent loud thumps.
2. Setting Gain Levels: For each active channel, speak or play into the microphone/instrument at its loudest expected level. Slowly turn up the GAIN kontrole līdz CLIP LED briefly flashes. Then, back off the GAIN slightly so the CLIP LED no longer illuminates. This ensures optimal signal-to-noise ratio without distortion.

4. Using the EQ: Izmantojiet AUGSTS, MID, un LOW controls to shape the tone of each input. Turning a knob clockwise boosts the frequency, while turning it counter-clockwise cuts it. Start with all EQ knobs at the center (0 dB) position.
5. Panning/Balancing: Izmantojiet PAN knob for mono channels (1-2) to position them in the stereo field. Use the BAL knob for stereo channels (3/4, 5/6) to adjust the left/right balance.
6. Applying Effects (FX Send): Pagrieziet FX sūtīšana knob on the desired channel to send its signal to the external effects processor. Adjust the effect unit's wet/dry mix and the AUX ATGRIEŠANA level on the mixer to blend the effect into the main mix.
7. Main Mix Level: Pielāgojiet GALVENĀ MIX knob to control the overall output volume. Monitor the LĪMEŅA METRI to ensure the main mix is not clipping.
8. Uzraudzība: Izmantojiet CONTROL ROOM/PHONES knob to adjust the listening volume for your headphones or control room monitors.

6. Apkope

Pareiza apkope nodrošina jūsu miksera ilgmūžību un optimālu veiktspēju.

7. Traucējummeklēšana

If you encounter issues with your Behringer UB802, refer to the following common problems and solutions.

• Nav jaudas:
  • Pārliecinieties, vai strāvas adapteris ir droši pievienots gan mikserim, gan darbojošai strāvas kontaktligzdai.
  • Pārbaudiet, vai strāvas kontaktligzda ir aktīva.
  • Check if the correct power adapter is being used (only the one supplied by Behringer).
• Nav skaņas izvades:
  • Check all cable connections from input sources to the mixer, and from the mixer's outputs to your amppacēlājs/skaļruņi.
  • Nodrošināt kanālu LĪMENIS knobs and the GALVENĀ MIX knob are turned up.
  • Pārbaudiet, vai GAIN controls are set appropriately and the CLIP LED is not constantly lit.
  • If using condenser microphones, ensure PHANTOM POWER (+48V) ir aktivizēts.
  • Check the volume levels on your amppacēlājs vai skaļruņi ar barošanu.
• Izkropļota skaņa:
  • Samaziniet GAIN control for the offending channel if the CLIP LED is frequently flashing.
  • Lower the channel LĪMENIS or GALVENĀ MIX līmenī.
  • Pirms ievades avota nonākšanas mikserī pārbaudiet, vai tajā nav kropļojumu.
• Dūkšana vai troksnis:
  • Ensure all audio cables are properly shielded and in good condition.
  • Try to isolate the mixer's power supply from other noisy electrical devices.
  • Pārbaudiet, vai nav zemējuma cilpu, pārliecinoties, ka visas iekārtas ir pievienotas vienai un tai pašai strāvas ķēdei, vai, ja nepieciešams, izmantojot zemējuma cilpas izolatoru.
