   • Connect the GND terminal to a clean, bare metal chassis ground point in the vehicle.
   • Connect the REM terminal to the remote turn-on lead from your head unit. This will turn the equalizer on and off with your head unit.
2. Audio Input Connection:
   • Connect the RCA outputs from your head unit (CD/Radio) to the CD Input RCAs on the equalizer.
   • If using an auxiliary device, connect its audio output to the AUX Input RCAs.
3. Audio Output Connection:
   • Connect the Front Output RCAs to the front channel inputs of your amplifier.
   • Connect the Rear Output RCAs to the rear channel inputs of your amplifier.
   • Connect the Sub Output RCAs to the subwoofer channel input of your amplifier.

Once all connections are made, reconnect the vehicle's negative battery terminal.

4. Operating Instructions

Follow these steps to operate your Lnrueg MT-X708 equalizer and customize your audio experience.

1. Power On: Ensure your head unit is turned on. The equalizer will power on automatically via the remote turn-on connection.
2. Select Input Source: Press the CD/AUX button to switch between your primary (CD) and auxiliary (AUX) audio sources.
3. Adjust Master Volume: Use the Volume knob to set the overall listening level. Start with a low volume and gradually increase it.
4. Set Subwoofer Levels:
   • Adjust the Sub Vol knob to control the bass output level from your subwoofer.
   • Use the Sub Freq knob to set the desired crossover point for the subwoofer, determining which low frequencies are sent to it.
5. Balance Front/Rear: Use the Fader knob to adjust the audio balance between your front and rear speakers.
6. Equalization Adjustment:
   • Individually adjust the 7 equalization sliders (63Hz, 125Hz, 315Hz, 750Hz, 2.2KHz, 6KHz, 12KHz) to boost or cut specific frequency ranges.
   • Move a slider up to +12dB to boost that frequency, or down to -12dB to cut it.
   • Experiment with different settings to achieve your desired sound profile. For example, boosting 63Hz and 125Hz can enhance bass, while adjusting 2.2KHz and 6KHz can affect vocal clarity.

5. Maintenance

To ensure the longevity and proper functioning of your equalizer, follow these simple maintenance guidelines:

• Cleaning: Use a soft, dry cloth to wipe the exterior of the unit. Avoid using harsh chemicals, solvents, or abrasive cleaners, as these can damage the finish and controls.
