• MAIN INPUT LEVEL (dB): Controls the input level for the main stereo input.
• MAIN LINK: Button to link channels for stereo operation.
• MAIN OUTPUT LEVEL (dB): Controls the output level for the main stereo output.
• SPLIT/MIX Switch: Determines whether the individual channel operates in splitter or mixer mode.
• LEVEL: Adjusts the input/output level for individual channels.
• LEFT/RIGHT BALANCE/PAN: Controls the balance (in splitter mode) or pan (in mixer mode) for individual channels.
• LED Meters: Provide visual indication of input and output signal levels.
• POWER Switch: Turns the unit on or off.

4.2. Rear Panel

The rear panel houses all audio input and output connections, as well as the power inlet.

• XLR Inputs/Outputs: Balanced connections for professional audio equipment.
• 1/4-inch TRS Inputs/Outputs: Balanced/unbalanced connections for various audio devices.

5. Setup

Follow these steps to set up your Ultralink Pro MX882:

1. Rack Mounting: If desired, mount the MX882 into a standard 19-inch equipment rack using appropriate rack screws. Ensure sufficient space for ventilation.
2. Power Connection: Connect the supplied AC power cable to the power inlet on the rear panel and then to a suitable power outlet. Do not power on the unit yet.
3. Audio Connections: Connect your audio sources (e.g., mixers, instruments, playback devices) to the desired input channels on the rear panel using XLR or 1/4-inch TRS cables. Connect your audio destinations (e.g., amplifiers, recording interfaces, other mixers) to the corresponding output channels.
4. Initial Settings: Ensure all LEVEL controls on the front panel are set to their minimum position.
5. Power On: Turn on the MX882 using the POWER switch on the front panel.
6. System Power Up: Power on your connected audio equipment, typically starting with sources and ending with amplifiers/monitors.

6. Operating Modes

The MX882 offers flexible operation as either a mixer or a splitter, with each channel configurable independently.

6.1. Mixer Mode (8 In / 2 Out)

In mixer mode, the MX882 combines up to eight mono input signals into a stereo output. This is ideal for sub-mixing multiple sources before sending them to a main mixer or recording device.

• Set the SPLIT/MIX switch for each desired channel to the 'MIXER' position.
• Connect your mono audio sources to the individual channel inputs (CH 1 IN to CH 8 IN) on the rear panel.
• Adjust the LEVEL control for each channel to achieve the desired input gain.
• Use the LEFT/RIGHT BALANCE/PAN control to position each channel within the stereo field.
• The combined stereo signal will be available at the MAIN OUT L and MAIN OUT R connections. Adjust the MAIN OUTPUT LEVEL as needed.

6.2. Splitter Mode (2 In / 8 Out)

In splitter mode, the MX882 takes a stereo input signal and distributes it to up to eight individual mono outputs. This is useful for sending a main mix to multiple amplifiers, recording devices, or monitor systems.

• Set the SPLIT/MIX switch for each desired channel to the 'SPLITTER' position.
• Connect your stereo audio source to the MAIN IN L and MAIN IN R connections on the rear panel.
• Adjust the MAIN INPUT LEVEL to set the overall input gain.
• Each channel's output (CH 1 OUT to CH 8 OUT) will receive a mono sum of the main stereo input.
• Use the LEVEL control for each channel to adjust its individual output level.
• The LEFT/RIGHT BALANCE/PAN control in splitter mode allows you to select whether the channel receives the left, right, or a sum of both main inputs.

6.3. Level Matching Amplifier / DI Box (6 In / 6 Out)

The MX882 can also function as a level matching amplifier or a direct inject (DI) box, converting signal levels between -10 dBV (consumer level) and +4 dBu (professional level).

• This functionality is inherent in the design, allowing you to connect devices with different nominal operating levels without signal degradation.
• By using individual channels, you can convert unbalanced signals to balanced, or vice-versa, and adjust levels precisely.

7. Maintenance

Proper maintenance ensures the longevity and optimal performance of your MX882.

• Cleaning: Use a soft, dry cloth to clean the exterior of the unit. Avoid abrasive cleaners or solvents.
• Ventilation: Ensure that the ventilation openings are free from dust and debris.
• Connections: Periodically check all cable connections for secure fit and signs of wear.
• Storage: If storing the unit for an extended period, disconnect it from power and store in a dry, dust-free environment.

8. Troubleshooting

If you encounter issues with your MX882, refer to the following common troubleshooting steps:

• No Power:
  • Check if the power cable is securely connected to both the unit and the power outlet.
  • Ensure the power outlet is functional.
  • Verify the POWER switch on the front panel is in the 'ON' position.
• No Sound Output:
  • Check all audio cable connections.
  • Ensure the LEVEL controls for the relevant channels and main outputs are not set to minimum.
  • Verify the SPLIT/MIX switches are set correctly for your desired operation (mixer or splitter).
  • Check the input and output levels of connected external equipment.
  • Observe the LED meters for signal presence.
• Distorted Sound:
  • Reduce the LEVEL controls on the MX882 and/or the output levels of your source equipment to prevent clipping (indicated by red LEDs).
  • Ensure all cables are in good condition and correctly connected.
• Hum or Noise:
  • Ensure all connections are balanced where possible (using XLR or TRS cables).
  • Check for ground loops. Try connecting all audio equipment to the same power strip.
  • Keep audio cables away from power cables.

If the issue persists, contact Behringer customer support or a qualified service technician.
