3.1 Placering

Optimal placement of the Tzero MKIII is crucial for achieving the best bass performance. While it is a compact unit designed to fit in various spaces, consider the following:

• Hjørneplacering: Placing the subwoofer in a corner often provides the most efficient and impactful bass output, pressurizing the room effectively.
• Near Main Speakers: For seamless integration with your main speakers, try placing the subwoofer close to them. This helps create a cohesive soundstage.
• Lytteposition: Experiment with placement relative to your primary listening position. Small adjustments can significantly impact bass response.

3.2 Forbindelser

The Tzero MKIII offers multiple input options to accommodate various audio systems. Refer to the rear panel for connection points.

• High-Level Input (Neutrik Speakon): This is the preferred connection method for music systems. Connect the supplied 10-meter high-level cable to the speaker output terminals of your amplifier (left and right main speaker terminals). This allows the subwoofer to receive the same signal as your main speakers, ensuring seamless integration and superior musicality.
• Lavniveauindgang (RCA): For systems without high-level outputs or for dedicated LFE (Low-Frequency Effects) channels in home theater setups.
  • Lavt niveau input: Use a single RCA cable (not included) to connect from your receiver's subwoofer output (LFE or Sub Out) to the "LOW LEVEL INPUT" on the Tzero MKIII.
  • .1/LFE Input: For dedicated LFE channels, connect a single RCA cable (not included) from your receiver's LFE output to the ".1/LFE INPUT" on the Tzero MKIII. This input has a separate gain control for fine-tuning.
• Trådløs tilslutning (valgfrit): The Tzero MKIII is compatible with the optional REL HT-Air wireless system (sold separately). This 5.8 GHz wireless unit provides uncompressed wireless signal transmission for 0.1 or low-level inputs, offering flexible placement without long cable runs. Note that the HT-Air does not support high-level input.

4. Betjeningsvejledning

The Tzero MKIII features intuitive controls on its rear panel for precise integration with your audio system.

• HI/LOW LEVEL Control: Adjusts the overall volume of the subwoofer for both high-level and low-level inputs. Start with a low setting and gradually increase until the bass blends seamlessly with your main speakers.
• .1/LFE LEVEL Control: A dedicated volume control specifically for the .1/LFE input, allowing independent adjustment for home theater effects.
• CROSSOVER Control: This knob sets the upper frequency limit at which the subwoofer operates. Adjust this to blend the subwoofer's output with the low-frequency capabilities of your main speakers. Experiment to find the point where the bass sounds natural and not localized to the subwoofer.
• PHASE Switch (0°/180°): This switch adjusts the phase of the subwoofer's output relative to your main speakers. Listen for the setting that provides the most impactful and cohesive bass. Typically, one setting will sound fuller and more integrated than the other.
• STANDBY Switch (ON/ALWAYS ON):
  • PÅ: The subwoofer will enter a low-power standby mode when no audio signal is detected for a period. It will automatically wake up when a signal is present.
  • ALTID TIL: The subwoofer remains fully powered on at all times, regardless of audio signal presence. This is recommended for critical listening or if you experience delays in the subwoofer waking from standby.

4.1 Brugsscenarier

The Tzero MKIII is designed for optimal performance in both music and home theater applications:
