5. Setup

5.1 Placement

Proper placement is crucial for optimal sound reproduction. The LP-UNF monitors are designed for ultra-nearfield listening, typically at arm's length (around 0.8 meters or 31 inches) from the listener.

• Stereo Triangle: Position the speakers and your listening position to form an equilateral triangle.
• Ear Level: Ensure the tweeters are at approximately ear level.
• Isolation: Use isolation pads or stands to decouple the speakers from your desk surface, reducing unwanted vibrations.

5.2 Connections

The LP-UNF system consists of one primary (active) speaker and one secondary (passive) speaker. All inputs and controls are located on the primary speaker.

1. Connect Secondary Speaker: Use the provided inter-speaker cable to connect the 'Output to Secondary' port on the primary speaker to the 'Input From Primary' port on the secondary speaker. Ensure a secure connection.
2. Connect Audio Source: Choose one of the following input methods:
   • USB-C: Connect a USB-C cable from your computer or compatible device to the USB-C input on the primary speaker.
   • TRS: Connect balanced 1/4-inch TRS cables from your audio interface or mixer to the TRS inputs (L/R) on the primary speaker.
   • RCA: Connect RCA cables from your audio device to the RCA inputs (L/R) on the primary speaker.
   • Bluetooth: Refer to Section 6.3 for Bluetooth pairing instructions.
3. Connect Power: Connect the power adapter to the 24VDC input on the primary speaker, then plug the power cable into a wall outlet.

5.3 Boundary Compensation EQ Settings

The LP-UNF features DIP switches on the rear panel to adjust the speaker's frequency response based on its placement in your room. This helps to compensate for acoustic anomalies caused by boundaries (walls, desks).

Image: Close-up of the DIP switches on the LP-UNF rear panel, illustrating various settings for acoustic compensation.

Refer to the diagram on the rear panel for specific switch configurations. Common settings include:

• Free Space: For speakers placed on stands away from walls.
• On Desk, Near Wall: For speakers placed on a desk close to a wall.
• On Desk, Corner: For speakers placed on a desk in a corner.
• +/- 2dB High Frequency: Adjusts the treble response.
• +/- 2dB Low Frequency: Adjusts the bass response.
• LED On/Off: Controls the front panel LED indicator.

Experiment with these settings to find the most accurate sound for your listening environment.

6. Operation
