2. Cyfarwyddiadau Diogelwch Pwysig

Please read these instructions carefully before operating your Behringer UB802 mixer. Retain these instructions for future reference.

• Ffynhonnell Pwer: Defnyddiwch yr addasydd pŵer a gyflenwir gyda'r uned yn unig. Sicrhewch fod y cyfainttage yn cyfateb i'ch cyflenwad pŵer lleol.
• Awyru: Peidiwch â rhwystro unrhyw agoriadau awyru. Gosodwch yn unol â chyfarwyddiadau'r gwneuthurwr.

• Ceblau: Amddiffynnwch y llinyn pŵer rhag cael ei gerdded ymlaen neu ei binsio, yn enwedig wrth blygiau, cynwysyddion cyfleustra, a'r pwynt lle maent yn gadael y cyfarpar.
• Gwasanaethu: Cyfeirio pob gwasanaeth i bersonél gwasanaeth cymwys. Mae angen gwasanaethu pan fydd y cyfarpar wedi'i ddifrodi mewn unrhyw ffordd, fel llinyn cyflenwad pŵer neu blwg wedi'i ddifrodi, hylif wedi'i ollwng neu wrthrychau wedi disgyn i'r offer, mae'r cyfarpar wedi bod yn agored i law neu leithder, nid yw'n gweithredu'n normal , neu wedi cael ei ollwng.

3. Rheolaethau a Chysylltwyr

3.1 Panel Uchaf Drosoddview

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

Ffigur 1: O'r brig i lawr 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 (UCHEL, CANOL, ISEL): 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. Anfon FX: 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. LEFEL: Adjusts the output volume of each individual channel to the main mix.
9. PŴER FFANTOM (+48V): A switch to activate +48V phantom power for condenser microphones connected to the XLR inputs.
10. LED CLIP: Illuminates when the input signal is too high, indicating potential clipping or distortion. Reduce the GAIN control if this LED lights up frequently.
11. MESURAU LEFEL: 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 Cysylltiadau Panel Cefn

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

Ffigur 2: Cefn 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. PŴER AC YN: Connect the supplied Behringer power adapter here. Use only the specified power supply.
2. ALLBWN PRIF (Chwith/Dde): 1/4" TRS outputs for connecting the main stereo mix to an amplifier, powered speakers, or a recording interface.
3. ANFON FX: 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. Gosod

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

1. Cysylltiad Pwer: 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. Cysylltiad Meicroffon/Offeryn:
   • For microphones, connect XLR cables to the MIC YN jacks (Channels 1-2). If using condenser microphones, activate the PHANTOM POWER (+48V) swits.
   • For line-level instruments (e.g., keyboards, guitars with preamps), connect 1/4" TS or TRS cables to the LLINELL YN jacks. Use Channels 3/4 or 5/6 for stereo sources.
3. Cysylltiad Allbwn: Cysylltwch y ALLBWN PRIF (Chwith/Dde) jacks to your amplifier, powered speakers, or audio interface using 1/4" TRS cables.
4. Monitro: Cysylltwch eich clustffonau i'r FFONAU jack or control room monitors to the YSTAFELL RHEOLI ALLAN jaciau.
5. External Effects (Optional): If using an external effects processor, connect the ANFON FX jack to the input of your effects unit. Then, connect the output of your effects unit to the DYCHWELYD AUX jack on the mixer.
6. Recording/Playback Devices (Optional): Cysylltwch y 2-TRACK OUT to the input of your recording device and the output of your playback device to the 2-TRACK IN.

5. Gweithredu'r Cymysgydd

This section provides guidance on operating your Behringer UB802 mixer.

1. Pŵer ar Dilyniant: 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 ENNILL rheoli hyd nes y 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.
3. Adjusting Channel Levels: Gosod pob sianel LEFEL knobs to their minimum position. Slowly bring up the LEVEL knob for each channel to achieve a balanced mix.
4. Using the EQ: Defnyddiwch y UCHEL, CANOLBARTH, a ISEL 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: Defnyddiwch y 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): Trowch i fyny'r Anfon FX knob on the desired channel to send its signal to the external effects processor. Adjust the effect unit's wet/dry mix and the DYCHWELYD AUX level on the mixer to blend the effect into the main mix.
7. Main Mix Level: Addaswch y PRIF MIX knob to control the overall output volume. Monitor the MESURYDDION LEFEL to ensure the main mix is not clipping.
8. Monitro: Defnyddiwch y CONTROL ROOM/PHONES knob to adjust the listening volume for your headphones or control room monitors.

  • Gwiriwch fod yr allfa bŵer yn weithredol.
  • Check if the correct power adapter is being used (only the one supplied by Behringer).
• Dim allbwn sain:
  • Check all cable connections from input sources to the mixer, and from the mixer's outputs to your ampllewyr/siaradwyr.
  • Ensure channel LEFEL knobs and the PRIF MIX knob are turned up.
  • Gwiriwch fod y ENNILL controls are set appropriately and the CLIP LED is not constantly lit.
  • If using condenser microphones, ensure PHANTOM POWER (+48V) yn cael ei actifadu.
  • Check the volume levels on your ampseinyddion neu seinyddion wedi'u pweru.
• Sain ystumiedig:
  • Lleihau'r ENNILL control for the offending channel if the CLIP LED is frequently flashing.
  • Lower the channel LEFEL or PRIF MIX lefel.
  • Check the input source for distortion before it reaches the mixer.
• Hwm neu Sŵn:
  • 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.
