• XLR Inputs (L/R, LFE): For connecting balanced audio signals from your mixer or audio interface.
• XLR Outputs (L/R, LFE/Sub): For passing the audio signal to your satellite speakers or other audio equipment.
• Unbalanced Connection (for SC203): If connecting EVE Audio SC203 speakers, use the dedicated unbalanced input. Refer to the SC203 manual for specific connection details.
• Power Connection: Connect the supplied AC power cord to the AC inlet on the rear panel of the TS107, then plug the other end into a grounded wall outlet.

3.4 Passive Radiator

The TS107 utilizes a passive radiator instead of a traditional bass reflex port. This design allows for a deeper and more controlled bass response, free from air turbulence noise often found in ported enclosures. The passive radiator works in conjunction with the active woofer to enhance low-frequency output efficiently.

4. Setup

4.1 Placement

The placement of your subwoofer significantly impacts its performance. Consider the following:

• Room Acoustics: Bass frequencies are heavily influenced by room dimensions and materials. Experiment with different positions to find the optimal sound.
• Corner Placement: Placing the subwoofer in a corner can increase bass output, but may also lead to boomy or uneven bass.
• Wall Proximity: Placing the subwoofer close to a wall generally reinforces bass.
• Listening Position: The subwoofer should ideally be placed in a position that provides smooth bass response at your primary listening position.
• Ventilation: Ensure adequate space around the unit for proper ventilation, especially at the rear panel.

4.2 Connections

Before making any connections, ensure the TS107 and all connected audio equipment are powered off.

1. Connect Audio Source: Use balanced XLR cables to connect the outputs of your audio interface or mixer to the L and R XLR Inputs on the TS107 rear panel. For LFE (Low-Frequency Effects) input, use the dedicated LFE In.
2. Connect Satellite Speakers: If using satellite speakers, connect the L and R XLR Outputs of the TS107 to the inputs of your satellite speakers. This allows the TS107 to manage the crossover frequencies.
3. Unbalanced Connection (for SC203): If connecting EVE Audio SC203 speakers, use the dedicated unbalanced input. Refer to the SC203 manual for specific connection details.
4. Power Connection: Connect the supplied AC power cord to the AC inlet on the rear panel of the TS107, then plug the other end into a grounded wall outlet.

Note: Always use high-quality balanced cables for optimal performance and to minimize noise.

5. Operating the TS107

5.1 Powering On/Off

After all connections are made, you can power on your system. It is recommended to power on your subwoofer last and power it off first to prevent any thumps or pops.

• To Power On: Flip the power switch on the rear panel to the 'ON' position.
• To Power Off: Flip the power switch on the rear panel to the 'OFF' position.

5.2 Adjusting Controls

The TS107 offers comprehensive controls to integrate seamlessly with your main monitors and room acoustics.

• Subwoofer Volume: Use the dedicated "Subwoofer Volume" knob on the front panel to adjust the output level of the subwoofer. Start with a low setting and gradually increase until the bass blends well with your main speakers.
• System Volume / Setting Knob: This knob controls the overall system volume. Pressing and holding this knob typically allows access to advanced settings:
  • Satellite Filters: Switch between "Full Range" (no high-pass filter applied to satellite outputs) and "80Hz" (high-pass filter at 80Hz applied to satellite outputs). The 80Hz setting is commonly used in studio setups.
  • Phase Switch (0°, 180°): Adjust the phase of the subwoofer relative to your main speakers. Experiment with both settings to find the one that provides the most coherent bass response at your listening position. This helps prevent phase cancellations.
  • Variable Subwoofer Filter Frequencies (60-140Hz): This control sets the upper frequency limit for the subwoofer. Adjust this to match the low-frequency cutoff of your main speakers, ensuring a smooth transition between the subwoofer and satellites.

Tip: For optimal integration, use test tones or familiar music to fine-tune the subwoofer's volume, phase, and crossover frequency. The goal is for the subwoofer to disappear into the soundstage, providing a natural extension of your main speakers' bass response.

6. Maintenance

Proper maintenance ensures the longevity and optimal performance of your EVE Audio TS107 subwoofer.

• Cleaning: Use a soft, dry, lint-free cloth to clean the exterior surfaces of the subwoofer. For stubborn marks, a slightly damp cloth can be used, but ensure no liquid enters the unit. Do not use abrasive cleaners, waxes, or solvents.
• Dust: Regularly dust the ventilation openings to prevent accumulation, which can impede airflow and lead to overheating.
• Environment: Keep the subwoofer in a clean, dry environment, away from direct sunlight, excessive heat, and moisture.
• Cables: Periodically check all audio and power cables for any signs of wear or damage. Replace damaged cables immediately.
