3. Opsætning

3.1 Udpakning og inspektion

Carefully remove the speaker from its packaging. Inspect the unit for any signs of damage that may have occurred during shipping. Retain the original packaging for future transport or storage.

3.2 Højttalerplacering

Position the speaker in a location that provides optimal sound coverage for your audience. Consider the 90x50 degree coverage pattern when determining placement. Ensure the speaker is stable and securely mounted if suspended.

• Anchor Plates: Three anchor plates are provided for single-stud fittings, with an additional pair on the bottom of the speaker.

3.4 Tilslutning til en Amplivligere

The ZX3-90B is a passive speaker and requires an external amplifier. Use high-quality speakON cables for connection. Ensure the amplifier's power output matches the speaker's power handling capabilities (600W continuous, 2400W peak) to prevent damage.

• Standardforbindelse: Connect the speakON cable from the amplifier's output to one of the speakON input connectors on the ZX3-90B.
• bi-Amped Connection: For bi-amplification, separate amplifier channels are used for the low-frequency (LF) and high-frequency (HF) drivers. Consult the speaker's wiring diagram (typically found on the input plate or in detailed technical specifications) for correct speakON pin assignments for LF and HF. This method requires an external crossover.

Sørg altid for amplifier is turned off before making any connections to prevent electrical shock or equipment damage. Verify correct polarity (+ to + and - to -) for all connections.

4. Betjening

4.1 Powering On and Initial Sound Check

1. Sørg for, at alle forbindelser er sikre og korrekte.
2. Turn on your audio mixer and any signal processors first.
3. Tænd for amplifier(s) connected to the ZX3-90B. Start with the amplifier gain at its lowest setting.
4. Øg gradvist amplifier gain and feed a low-level audio signal to the system.
5. Listen for sound and slowly increase the volume to a comfortable listening level.

4.2 Forstærkning Staging

Korrekt gevinst staging throughout your audio system is crucial for optimal sound quality and to prevent distortion or damage. Ensure that each component in the signal chain (mixer, processors, amplifier) is operating at its optimal input and output levels without clipping.

4.3 Bi-Amplification (If Applicable)

If operating in bi-amp mode, ensure your external crossover is correctly configured for the ZX3-90B's drivers. Refer to Electro-Voice's technical documentation for recommended crossover points and slopes. Incorrect crossover settings can lead to poor sound quality or driver damage.
