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 (TINGGI, SEDANG, RENDAH): 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. Kirim Valas: 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. TINGKAT: 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. KLIP 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. PENGUKUR LEVEL: LED indicators displaying the overall output level of the main mix. Aim for levels around 0 dB during normal operation.
12. CAMPURAN UTAMA: 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 Sambungan Panel Belakang

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

1. DAYA AC MASUK: 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. KIRIM FX: 1/4" TS output for sending the combined FX send signal to the input of an external effects processor.
4. PENGEMBALIAN AUX: 1/4" TS input for receiving the processed signal back from an external effects processor.

4. Pengaturan

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

1. Sambungan Daya: 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. Koneksi Mikrofon/Instrumen:
   • For microphones, connect XLR cables to the MIC DI jacks (Channels 1-2). If using condenser microphones, activate the PHANTOM POWER (+48V) mengalihkan.
   • For line-level instruments (e.g., keyboards, guitars with preamps), connect 1/4" TS or TRS cables to the GARIS MASUK jacks. Use Channels 3/4 or 5/6 for stereo sources.
3. Koneksi Keluaran: Hubungkan MAIN OUT (L/R) jack ke milikmu amplifier, powered speakers, or audio interface using 1/4" TRS cables.
4. Pemantauan: Hubungkan headphone Anda ke TELEPON jack or control room monitors to the RUANG KONTROL KELUAR jack.
5. Efek Eksternal (Opsional): If using an external effects processor, connect the KIRIM FX jack to the input of your effects unit. Then, connect the output of your effects unit to the PENGEMBALIAN AUX jack on the mixer.
6. Recording/Playback Devices (Optional): Hubungkan 2-TRACK OUT to the input of your recording device and the output of your playback device to the 2-TRACK IN.

5. Mengoperasikan Mixer

This section provides guidance on operating your Behringer UB802 mixer.

1. Urutan Pengaktifan: 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 MEMPEROLEH kontrol sampai KLIP 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: Tetapkan semua saluran TINGKAT knobs to their minimum position. Slowly bring up the LEVEL knob for each channel to achieve a balanced mix.
4. Using the EQ: Gunakan TINGGI, PERTENGAHAN, Dan RENDAH 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: Gunakan PANCI 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): Nyalakan FX Kirim knob on the desired channel to send its signal to the external effects processor. Adjust the effect unit's wet/dry mix and the PENGEMBALIAN AUX level on the mixer to blend the effect into the main mix.
7. Level Pencampuran Utama: Sesuaikan CAMPURAN UTAMA knob to control the overall output volume. Monitor the PENGUKUR LEVEL to ensure the main mix is not clipping.
8. Pemantauan: Gunakan CONTROL ROOM/PHONES knob to adjust the listening volume for your headphones or control room monitors.

6. Pemeliharaan

Proper maintenance ensures the longevity and optimal performance of your mixer.

• Pembersihan: 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.
• Penyimpanan: Saat tidak digunakan dalam jangka waktu lama, simpan mixer di tempat yang sejuk dan kering, jauh dari sinar matahari langsung dan suhu ekstrem. Pertimbangkan untuk menggunakan penutup debu.
• Pemutusan Daya: Always disconnect the power adapter from the wall outlet if the unit will not be used for a long time.

  • Ensure channel TINGKAT knobs and the CAMPURAN UTAMA knob are turned up.
  • Verifikasi bahwa MEMPEROLEH controls are set appropriately and the KLIP LED is not constantly lit.
  • If using condenser microphones, ensure PHANTOM POWER (+48V) diaktifkan.
  • Check the volume levels on your amplifier atau speaker bertenaga.
• Suara Terdistorsi:
  • Mengurangi MEMPEROLEH control for the offending channel if the KLIP LED is frequently flashing.
  • Lower the channel TINGKAT or CAMPURAN UTAMA tingkat.
  • Check the input source for distortion before it reaches the mixer.
• Hum atau Kebisingan:
  • Pastikan semua kabel audio terlindungi dengan baik dan dalam kondisi bagus.
  • 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.
