Connection Steps:

  1. Ensure your amplifier is turned off and its volume is set to minimum.
  2. Connect a speaker cable from the amplifier's output to one of the NL4 input connectors on the SRX815.
  3. If linking multiple passive speakers, use the NL4 pass-through connector to connect to the next speaker. Ensure your amplifier can handle the combined impedance.

The principles of connecting audio sources are similar for passive speakers, though the SRX815 requires an external amplifier.

4. Operating the SRX815

4.1 Powering On

Since the SRX815 is a passive speaker, it does not have its own power switch. Power is supplied by the external amplifier. Ensure the amplifier is connected correctly before powering it on.

  1. Verify all speaker cables are securely connected between the SRX815 and the amplifier.
  2. Ensure the amplifier's volume is at its minimum setting.
  3. Power on your external amplifier.
  4. Gradually increase the amplifier's volume to the desired listening level.

4.2 Audio Playback

Once the amplifier is powered on and connected, audio will be reproduced through the SRX815. Adjust the volume and equalization settings on your external mixer or amplifier to achieve the desired sound.

The SRX815 is a 2-way bass reflex system, providing a wide frequency range suitable for various applications, from live performances to public speaking.

5. Maintenance

Regular maintenance helps prolong the life and performance of your SRX815 speaker.

  • Cleaning: Use a soft, dry cloth to clean the exterior of the speaker. Avoid abrasive cleaners or solvents. For the grille, a soft brush or vacuum cleaner can remove dust.
  • Storage: When not in use, store the speaker in a dry, temperature-controlled environment. If possible, use a protective cover to prevent dust accumulation and physical damage.
  • Inspection: Periodically check all cables and connectors for wear or damage. Ensure mounting hardware is secure.
