4. Setup

4.1 Unpacking

Carefully remove the speaker from its packaging. Inspect the unit for any signs of damage that may have occurred during shipping. If damage is found, contact your dealer immediately. Retain the original packaging for future transport or storage.

4.2 Placement

The Yorkville NX35-2 is designed for versatile placement, including floor monitoring (wedge), pole mounting, or suspension. Ensure the speaker is placed on a stable, level surface or securely mounted using appropriate hardware. For optimal sound dispersion, consider the audience area and room acoustics. Avoid placing speakers directly against walls or in corners, which can lead to exaggerated bass response.

4.3 Connections

As a passive speaker, the NX35-2 requires an external power amplifier.

1. Power Amplifier Selection: Choose a power amplifier that can deliver sufficient power to the NX35-2 (up to 500 watts) at its nominal impedance. Ensure the amplifier's output impedance matches the speaker's impedance.
2. Speaker Cable: Use high-quality, appropriately gauged speaker cables with secure connectors (e.g., Speakon or 1/4-inch TS, depending on the speaker's input connectors). Ensure the cable length is minimized to reduce signal loss.
3. Connecting to Amplifier: With the amplifier turned OFF and its volume controls set to minimum, connect one end of the speaker cable to the input connector on the NX35-2. Connect the other end to the corresponding output channel on your power amplifier. Ensure correct polarity (+ to + and - to -) if using bare wire connections.
4. Multiple Speakers: If connecting multiple NX35-2 speakers, consult your amplifier's manual for proper wiring configurations (e.g., parallel or series) to maintain a safe impedance load for the amplifier.

5. Operating Instructions

1. Initial Power-Up: After all connections are made, turn on your audio source (mixer, instrument, etc.), then your power amplifier. Start with the amplifier's volume at its lowest setting.
2. Volume Adjustment: Gradually increase the amplifier's volume to the desired listening level. Monitor the sound for any distortion. If distortion occurs, reduce the volume.
3. System Gain Staging: Ensure proper gain staging throughout your audio chain (source, mixer, processor, amplifier) to prevent clipping and maximize signal-to-noise ratio.
4. Power Down Sequence: When finished, turn down the amplifier's volume, then turn off the amplifier, followed by your audio source. This prevents loud pops or thumps through the speakers.

6. Maintenance

• Cleaning: Clean the speaker cabinet with a soft, dry cloth. Do not use abrasive cleaners, solvents, or waxes. The grille can be gently vacuumed to remove dust.
• Storage: When not in use for extended periods, store the speaker in a dry, temperature-controlled environment, ideally in its original packaging or a protective cover.
• Inspection: Periodically check all cables and connectors for wear or damage. Ensure mounting hardware (if applicable) remains secure.
• Avoid Moisture: Protect the speaker from direct exposure to moisture, rain, or extreme humidity.
