3.1 Iphaneli ephezulu ngaphezuluview

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

Umfanekiso 1: Phezulu-phansi 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. FX Thumela: 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. IZINGA: 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. I-CLIP LED: Illuminates when the input signal is too high, indicating potential clipping or distortion. Reduce the GAIN control if this LED lights up frequently.
11. LEVEL MTERS: 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.

1. AMANDLA E-AC KU: 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. FX THUMELA: 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. Setha

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

1. Ukuxhuma kwamandla: 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. Microphone/Instrument Connection:
   • For microphones, connect XLR cables to the I-MIC IN jacks (Channels 1-2). If using condenser microphones, activate the PHANTOM POWER (+48V) shintsha.
   • For line-level instruments (e.g., keyboards, guitars with preamps), connect 1/4" TS or TRS cables to the UMGQE jacks. Use Channels 3/4 or 5/6 for stereo sources.
3. Uxhumano Lokukhiphayo: Xhuma i- MAIN OUT (L/R) jacks to your amplifier, powered speakers, or audio interface using 1/4" TRS cables.
4. Ukuqapha: Xhuma ama-headphone akho ku- AMAPHONE jack or control room monitors to the IGUMBI LOKULAWULA NGAPHANDLE ojeke.
5. External Effects (Optional): If using an external effects processor, connect the I-FX THUMELA jack to the input of your effects unit. Then, connect the output of your effects unit to the AUX BUYELA jack on the mixer.
6. Recording/Playback Devices (Optional): Xhuma i- 2-TRACK OUT to the input of your recording device and the output of your playback device to the 2-TRACK IN.

5. Ukusebenzisa Isixhumi

This section provides guidance on operating your Behringer UB802 mixer.

1. Amandla Ekulandelaneni: 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 ZUZA ukulawula kuze kube I-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: Setha sonke isiteshi LEVEL knobs to their minimum position. Slowly bring up the LEVEL knob for each channel to achieve a balanced mix.
4. Using the EQ: Sebenzisa i- PHEZULU, MID, futhi PHANSI 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: Sebenzisa i- I-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): Khuphula FX Thumela 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 BUYELA level on the mixer to blend the effect into the main mix.
7. Main Mix Level: Lungisa i- INGXENYE EBALULEKILE knob to control the overall output volume. Monitor the IZINGA AMAmitha to ensure the main mix is not clipping.
8. Ukuqapha: Sebenzisa i- CONTROL ROOM/PHONES knob to adjust the listening volume for your headphones or control room monitors.

6. Isondlo

Ukugcinwa kahle kuqinisekisa ukuthi umshini wakho wokuxuba uphila isikhathi eside futhi usebenza kahle.

• Ukuhlanza: 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.
• Isitoreji: Uma ingasetshenziswa isikhathi eside, gcina i-mixer endaweni epholile, eyomile, kude nelanga eliqondile namazinga okushisa aphezulu. Cabangela ukusebenzisa ikhava yothuli.
• Ukunqanyulwa kwamandla: Always disconnect the power adapter from the wall outlet if the unit will not be used for a long time.

7. Ukuxazulula izinkinga

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

• Awekho Amandla:
  • Ensure the power adapter is securely connected to both the mixer and a working power outlet.

  • Check if the correct power adapter is being used (only the one supplied by Behringer).
• Akukho okukhipha umsindo:
  • Check all cable connections from input sources to the mixer, and from the mixer's outputs to your ampi-lifier/izikhulumi.
  • Ensure channel LEVEL knobs and the INGXENYE EBALULEKILE knob are turned up.
  • Qinisekisa ukuthi i- ZUZA controls are set appropriately and the I-CLIP LED is not constantly lit.
  • If using condenser microphones, ensure PHANTOM POWER (+48V) icushiwe.
  • Hlola amazinga evolumu ku- ampi-lifier noma izipikha ezinamandla.
• Umsindo Ohlanekezelwe:
  • Yehlisa ZUZA control for the offending channel if the I-CLIP LED is frequently flashing.
  • Lower the channel LEVEL or INGXENYE EBALULEKILE izinga.
  • Check the input source for distortion before it reaches the mixer.
• Umsindo noma umsindo:
  • 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.
