PROEL BULK515LU3 - 3.5mm Stereo Mini Jack Audio Extension Cable (3 Meters)

Optimize your audio connections and eliminate distance limitations with the Proel BULK515LU3 , a professional extension cable designed for reliability and sound fidelity. Part of Proel's renowned Bulk series, this accessory is essential for any audio setup, whether in a home studio, multimedia office, or home entertainment system. Its robust construction ensures lossless audio signal transmission, maintaining sound integrity from the source to your headphones or speakers.

This cable acts as a high-quality bridge between your devices, providing an additional 3 meters of freedom . Unlike generic cables that can introduce static or attenuate high frequencies, the BULK515LU3 is constructed with premium conductive materials and effective shielding. Its TRS (Tip-Ring-Sleeve) connectors allow for the transmission of balanced or unbalanced stereo signals, making it a versatile tool for various analog audio applications. The molded design of the connectors ensures superior tensile strength, protecting the internal solder joints from everyday wear and tear.

Main features

  • Extended length: Offers an additional 3 meters of reach, ideal for connecting distant devices without moving the source equipment.
  • 3.5mm TRS connectors: Equipped with a male connector on one end and a female socket on the other, compatible with the vast majority of consumer and pro-audio devices (smartphones, sound cards, computers, MP3 players).
  • Molded construction: The connectors are injection molded directly onto the cable, providing excellent strain relief and mechanical durability.
  • Clean signal: Designed to minimize interference and background noise, ensuring a clear listening experience.
  • Flexibility and resistance: The outer cover is robust yet flexible, preventing excessive tangling and facilitating its collection and storage.

Benefits for the user

The main benefit of the Proel BULK515LU3 is convenience without sacrificing quality . Many users find themselves limited by the short cables that come with studio headphones or desktop speaker systems. This cable eliminates that restriction, allowing you to sit comfortably on your couch while watching a movie or move freely around your recording studio while monitoring a mix. Furthermore, by using professional-grade components, you can be sure you're not introducing a bottleneck into your audio chain; your music, vocals, and effects will sound exactly as they were originally intended.

Use cases

  • Headphone Extension: Ideal for lengthening your headphone cable when connecting to the back of a tower computer or a remotely located amplifier.
  • Home Studio: Perfect for connecting reference monitors or sending headphone signals to musicians within the same room without strain on the cables.
  • Multimedia Systems: Useful for connecting the audio output of a television or projector to an external sound system located several meters away.
  • Offices and Conferences: Facilitates the connection of laptops to speaker systems in large meeting rooms where fixed cabling does not reach the table.

Frequently Asked Questions

Is this cable suitable for microphones?
Yes, as long as the microphone uses a 3.5 mm TRS mini-jack connector. If it's a mobile phone microphone (TRRS with 3 black rings), you might need an additional adapter, but for standard TRS camera or PC microphones, it works perfectly as an extension cable.

Does adding 3 meters result in a loss of sound quality?
With a high-quality cable like the Proel Bulk series, signal loss over 3 meters is imperceptible to the human ear in standard applications. The cable is designed to maintain impedance and clarity.

Is it a stereo or mono cable?
It's a cable with TRS connectors, meaning it can carry a standard stereo (left/right) signal. It can also function as a balanced mono cable when used with professional audio equipment that requires that specific configuration.
