3. Stýringar og tengi

3.1 Yfirborð yfirview

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

Mynd 1: Ofan frá og niður 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. Jöfnun (HÁ, MIÐ, LÁG): 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 Senda: 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. STIG: 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. 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. STIGMÆRAR: 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 Tengingar að aftan

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

Mynd 2: Aftan 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. AC POWER IN: Connect the supplied Behringer power adapter here. Use only the specified power supply.
2. AÐALÚTGANGUR (V/H): 1/4" TRS outputs for connecting the main stereo mix to an amplifier, powered speakers, or a recording interface.
3. FX SEND: 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. Uppsetning

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

1. Rafmagnstenging: 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. Tenging við hljóðnema/hljóðfæri:
   • For microphones, connect XLR cables to the MIC IN jacks (Channels 1-2). If using condenser microphones, activate the PHANTOM POWER (+48V) skipta.
   • Fyrir hljóðfæri á línustigi (t.d. hljómborð, gítara með forstillingu)amps), connect 1/4" TS or TRS cables to the LINE IN jacks. Use Channels 3/4 or 5/6 for stereo sources.
3. Úttakstenging: Tengdu við MAIN OUT (L/R) tengi við þinn amplifier, powered speakers, or audio interface using 1/4" TRS cables.
4. Eftirlit: Tengdu heyrnartólin þín við SÍMI jack or control room monitors to the STJÓRNHÚS ÚT tjakkar.
5. External Effects (Optional): If using an external effects processor, connect the FX SENDA jack to the input of your effects unit. Then, connect the output of your effects unit to the AUX AÐFERÐ jack on the mixer.
6. Recording/Playback Devices (Optional): Tengdu við 2-TRACK OUT to the input of your recording device and the output of your playback device to the 2-TRACK IN.

5. Notkun hrærivélarinnar

This section provides guidance on operating your Behringer UB802 mixer.

1. Power On Sequence: 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 ÁVIÐ stjórna þar til 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: Stilltu allar rásir STIG knobs to their minimum position. Slowly bring up the LEVEL knob for each channel to achieve a balanced mix.
4. Using the EQ: Notaðu HÁTT, MID, og LÁGT 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: Notaðu PANNA 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): Snúðu upp FX Senda 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 AÐFERÐ level on the mixer to blend the effect into the main mix.
7. Main Mix Level: Stilltu Aðalblöndun knob to control the overall output volume. Monitor the STIGMEÐLAR to ensure the main mix is not clipping.
8. Eftirlit: Notaðu CONTROL ROOM/PHONES knob to adjust the listening volume for your headphones or control room monitors.

6. Viðhald

Rétt viðhald tryggir langlífi og bestu mögulegu afköst hrærivélarinnar.

• Þrif: 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.
• Geymsla: 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.
• Rafmagnstenging: Always disconnect the power adapter from the wall outlet if the unit will not be used for a long time.

7. Bilanagreining

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

• Enginn kraftur:
  • Ensure the power adapter is securely connected to both the mixer and a working power outlet.
  • Gakktu úr skugga um að rafmagnstengið sé virkt.
  • Check if the correct power adapter is being used (only the one supplied by Behringer).
• Ekkert hljóðúttak:
  • Check all cable connections from input sources to the mixer, and from the mixer's outputs to your amplyftara/hátalarar.
  • Ensure channel STIG knobs and the Aðalblöndun knob are turned up.
  • Staðfestu að ÁVIÐ controls are set appropriately and the CLIP LED is not constantly lit.
  • If using condenser microphones, ensure PHANTOM POWER (+48V) er virkjaður.
  • Check the volume levels on your amphátalara eða hátalara.
• Bjagað hljóð:
  • Dragðu úr ÁVIÐ control for the offending channel if the CLIP LED is frequently flashing.
  • Lower the channel STIG or Aðalblöndun stigi.
  • Athugið hvort inntaksgjafinn sé röskun áður en hann nær hljóðblöndunartækinu.
• Suður eða hávaði:
  • 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.
