PROEL BULK140LU1 - Professional Balanced Audio Cable 6.3mm TRS Jack to 6.3mm TRS Jack (1 Meter)
The Proel BULK140LU1 is a high-quality interconnect solution designed for musicians, sound engineers, and technicians seeking reliability without compromising on budget. Part of Proel's acclaimed BULK series, this pre-assembled cable delivers clean and robust signal transmission, ideal for demanding environments such as professional recording studios, live stages, and rehearsal rooms.
This cable stands out for its balanced configuration (Stereo Jack to Stereo Jack), making it an essential tool for eliminating noise and electromagnetic interference in complex audio chains. Made with premium materials, the BULK140LU1 ensures that the integrity of your sound remains pure from source to destination, delivering the transparency your productions deserve.
The cable is constructed using Proel's HPC225 conductor, an industry standard for its flexibility and durability. Its S4CPRO series metal connectors are designed to withstand constant plug-and-disconnect cycles, ensuring a long lifespan even under heavy use. At 1 meter long, it's the perfect length for short, neat connections, preventing the excess cabling that often leads to clutter and signal loss in racks or studio setups.
Main features
-
Professional Connectors: Equipped with 6.3mm (1/4") stereo (TRS) jack connectors model PROEL S4CPRO with nickel-plated metal housing, which offer superior protection against bumps and pulls.
-
High Quality Conductor: Uses HPC225 cable with oxygen-free copper (OFC) conductors, minimizing oxidation and maximizing electrical conductivity for crystal-clear sound.
-
Effective Shielding: It features a copper spiral shield that provides superior coverage, protecting the signal against radio frequency interference (RFI) and electromagnetic interference (EMI).
-
Flexibility and Durability: Its flexible PVC outer cover allows for easy handling and perfect rolling, avoiding the memory effect and unwanted knots.
-
Balanced Configuration: Designed specifically to carry balanced signals, drastically reducing background noise over short and medium distances.
Product benefits
Choosing the Proel BULK140LU1 brings technical peace of mind to your audio setup. Its main benefit lies in signal integrity : being a balanced cable, it uses three conductors (positive, negative, and ground) to cancel out any noise the cable might pick up along its path. This results in audio with a much lower noise floor and greater dynamic range.
Furthermore, the robust metal connectors protect the internal solder points, which are often the weak point of budget cables. This translates into a smart long-term investment, as you won't have to constantly replace your cables. Its 1-meter length is ideal for keeping your workspace clean and organized, optimizing signal flow between adjacent devices.
Use cases
This cable is extremely versatile and is a fundamental piece in various situations:
-
Studio Monitor Connection: Ideal for connecting the output of your audio interface to your active near-field monitors, ensuring noise-free listening.
-
Effects and Processor Racks: Perfect for interconnecting external (outboard) equipment such as compressors, equalizers or preamps within a studio rack.
-
Pedalboards and Amplifiers: Useful for connecting stereo expression pedals or for effects loops that require TRS connections.
-
Patchbays: Essential for making front or rear connections in standard patchbay systems.
-
Stereo Instruments: Connecting synthesizers or keyboards with balanced outputs to mixing consoles.
Frequently Asked Questions
-
Is this cable suitable for connecting a regular electric guitar?
Although the connector physically fits, it's not the right one. Guitars typically use TS (mono/unbalanced) cables. This is a TRS (stereo/balanced) cable. If you use it with a guitar, it might work, but you won't get the benefits of balanced wiring, and it might not produce any sound with some active equipment.
-
What does "balanced" mean?
This means the cable has three internal conductors instead of two. This allows the audio equipment to eliminate noise and interference induced in the cable, resulting in a much cleaner sound.
-
Are the connectors repairable?
Yes, the S4CPRO series connectors are unscrewable and allow access to the solder joints, facilitating any future repairs if necessary.
-
Does the length include the connectors?
The nominal length of 1 meter generally refers to the length of the cable or the usable end-to-end distance, allowing convenient connections between nearby equipment.
