3. Контроле и конектори

3.1 Горња плоча прекоview

This section details the controls and connectors located on the top panel of your UB802 mixer.

Слика 1: Одозго надоле view of the Behringer UB802 mixer's control panel. This image displays the microphone and line inputs, gain controls, 3-band EQ sections, FX send, pan/balance controls, channel level knobs, main mix section, phantom power switch, and level meters.

1. MIC IN (Channels 1-2): XLR inputs for connecting microphones. These inputs provide +48V phantom power when activated.
2. LINE IN (Channels 1-2, 3/4, 5/6): 1/4" TRS inputs for connecting line-level sources such as keyboards, drum machines, or other audio devices. Channels 3/4 and 5/6 are stereo pairs.
3. GAIN (Channels 1-2): Adjusts the input sensitivity for the microphone and line inputs. Use this to set the optimal signal level before it reaches the mixer's internal processing.
4. EQ (HIGH, MID, LOW): Three-band equalizer controls for shaping the tone of each channel. HIGH affects frequencies around 12 kHz, MID around 2.5 kHz, and LOW around 80 Hz.
5. ФКС Сенд: This knob controls the amount of signal sent from the respective channel to the external effects processor connected to the FX Send output. It is a post-fader send.
6. PAN (Channels 1-2): Positions the mono signal within the stereo sound field (left to right).
7. BAL (Channels 3/4, 5/6): Adjusts the balance between the left and right signals of the stereo input channels.
8. НИВО: Adjusts the output volume of each individual channel to the main mix.
9. PHANTOM POWER (+48V): A switch to activate +48V phantom power for condenser microphones connected to the XLR inputs.
10. ЦЛИП ЛЕД: Illuminates when the input signal is too high, indicating potential clipping or distortion. Reduce the GAIN control if this LED lights up frequently.
11. МЈЕРИ НИВОА: LED indicators displaying the overall output level of the main mix. Aim for levels around 0 dB during normal operation.
12. MAIN MIX: Controls the overall output volume of the stereo main mix.
13. 2-TRACK IN/OUT: RCA connectors for connecting external recording devices or playback sources (e.g., CD players, tape decks).
14. CONTROL ROOM/PHONES: Output for connecting headphones or control room monitors. The level knob adjusts the volume for both.

3.2 Прикључци задње плоче

This section details the connections located on the rear panel of your UB802 mixer.

Слика 2: Задња страна view of the Behringer UB802 mixer. This image highlights the AC POWER IN port, MAIN OUT (L/R) jacks, FX SEND, and AUX RETURN jacks.

1. АЦ НАПАЈАЊЕ: Connect the supplied Behringer power adapter here. Use only the specified power supply.
2. MAIN OUT (L/R): 1/4" TRS outputs for connecting the main stereo mix to an amplifier, powered speakers, or a recording interface.
3. ФКС СЕНД: 1/4" TS output for sending the combined FX send signal to the input of an external effects processor.
4. AUX RETURN: 1/4" TS input for receiving the processed signal back from an external effects processor.

4. Подешавање

Follow these steps to set up your Behringer UB802 mixer for operation.

1. Прикључак за напајање: Ensure the mixer is switched off. Connect the supplied power adapter to the AC POWER IN on the rear panel and then plug it into a suitable power outlet.
2. Повезивање микрофона/инструмента:
   • For microphones, connect XLR cables to the МИЦ ИН jacks (Channels 1-2). If using condenser microphones, activate the PHANTOM POWER (+48V) прекидач.
   • For line-level instruments (e.g., keyboards, guitars with preamps), connect 1/4" TS or TRS cables to the ЛИНЕ ИН jacks. Use Channels 3/4 or 5/6 for stereo sources.
3. Излазна веза: Повежите MAIN OUT (L/R) jacks to your amplifier, powered speakers, or audio interface using 1/4" TRS cables.
4. Надгледање: Повежите слушалице са ПХОНЕС jack or control room monitors to the КОНТРОЛНА СОБА ОУТ јацкс.
5. External Effects (Optional): If using an external effects processor, connect the ФКС СЕНД jack to the input of your effects unit. Then, connect the output of your effects unit to the ПОМОЋНИ ПОВРАТАК jack on the mixer.
6. Recording/Playback Devices (Optional): Повежите 2-TRACK OUT to the input of your recording device and the output of your playback device to the 2-TRACK IN.

5. Руковање миксером

This section provides guidance on operating your Behringer UB802 mixer.

1. Редослед укључивања: 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 ГАИН контролу до ЦЛИП ЛЕД briefly flashes. Then, back off the GAIN slightly so the CLIP LED no longer illuminates. This ensures optimal signal-to-noise ratio without distortion.
3. Adjusting Channel Levels: Подесите све канале НИВО knobs to their minimum position. Slowly bring up the LEVEL knob for each channel to achieve a balanced mix.
4. Using the EQ: Користите ХИГХ, МИД, и ЛОВ 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: Користите ПАН knob for mono channels (1-2) to position them in the stereo field. Use the БАЛ knob for stereo channels (3/4, 5/6) to adjust the left/right balance.
6. Applying Effects (FX Send): Појачајте ФКС Сенд knob on the desired channel to send its signal to the external effects processor. Adjust the effect unit's wet/dry mix and the ПОМОЋНИ ПОВРАТАК level on the mixer to blend the effect into the main mix.
7. Main Mix Level: Подесите ГЛАВНИ МИКС knob to control the overall output volume. Monitor the НИВОМЈЕРИ to ensure the main mix is not clipping.
8. Надгледање: Користите CONTROL ROOM/PHONES knob to adjust the listening volume for your headphones or control room monitors.

6. Одржавање

Правилно одржавање осигурава дуготрајност и оптималне перформансе вашег миксера.

• Чишћење: Disconnect the power before cleaning. Use a soft, dry, lint-free cloth to wipe the surface of the mixer. Avoid using abrasive cleaners, solvents, or waxes, as these can damage the finish and controls.
• Складиштење: When not in use for extended periods, store the mixer in a cool, dry place, away from direct sunlight and extreme temperatures. Consider using a dust cover.
• Искључивање струје: Always disconnect the power adapter from the wall outlet if the unit will not be used for a long time.

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

• Нема напајања:
  • Ensure the power adapter is securely connected to both the mixer and a working power outlet.
  • Проверите да ли је утичница активна.
  • Check if the correct power adapter is being used (only the one supplied by Behringer).
• Нема излаза звука:
  • Check all cable connections from input sources to the mixer, and from the mixer's outputs to your ampлифиер/звучници.
  • Ensure channel НИВО knobs and the ГЛАВНИ МИКС knob are turned up.
  • Проверите да ли је ГАИН controls are set appropriately and the ЦЛИП ЛЕД is not constantly lit.
  • If using condenser microphones, ensure PHANTOM POWER (+48V) је активиран.
  • Check the volume levels on your ampлифиер или активни звучници.
• Изобличен звук:
  • Смањите ГАИН control for the offending channel if the ЦЛИП ЛЕД is frequently flashing.
  • Lower the channel НИВО or ГЛАВНИ МИКС ниво.
  • Check the input source for distortion before it reaches the mixer.
• Зујање или шум:
  • Ensure all audio cables are properly shielded and in good condition.
  • Try to isolate the mixer's power supply from other noisy electrical devices.
  • Check for ground loops by ensuring all equipment is connected to the same power circuit or using a ground loop isolator if necessary.
