PROEL ESO230LU3 - Esoteric Series Professional Balanced Audio Cable with Neutrik Connectors (3 Meters)
The PROEL ESO230LU3 represents the standard of excellence in signal transmission for professional audio environments, belonging to the acclaimed Esoteric series from the Italian brand. Meticulously designed for musicians, sound engineers, and technicians who cannot afford to compromise on the integrity of their sound, this 3-meter cable combines the precision engineering of Proel cables with the legendary reliability of Neutrik connectors.
At the heart of this assembly is the HPC250 cable, manufactured with high-purity oxygen-free copper (OFC). This material choice is critical to ensuring transparent signal transmission, minimizing high-frequency loss, and guaranteeing a dynamic response faithful to the original source. Unlike standard cables, the ESO230LU3 offers low capacitance and superior shielding, making it virtually immune to electromagnetic interference (EMI) and radio frequency interference (RFI), even in environments with high levels of electrical pollution.
The most notable feature of this model is the inclusion of genuine Neutrik NP3X connectors on both ends. These 6.3 mm (1/4") stereo/balanced (TRS) jack connectors are renowned worldwide for their robust construction. They feature a durable metal housing and Neutrik's unique mandrel-type strain relief system, which securely holds the cable from the inside to prevent breakage from pulling or heavy use during live performances. Whether connecting studio monitors, balanced synthesizers, or interfacing in a rack, the ESO230LU3 is the ultimate solution for a clean, professional audio chain.
Main features
-
Original Neutrik Connectors: Equipped with the NP3X model with nickel-plated housing and silver contacts, guaranteeing long-lasting connection cycles and optimal conductivity.
-
High Purity OFC Copper: Internal conductors made of oxygen-free copper for crystal-clear, color-free signal transfer.
-
Balanced Design (TRS): Three-pole configuration (Tip-Ring-Sleeve) that allows the transmission of balanced mono or stereo signals, drastically reducing background noise.
-
Flexible Covering: The soft PVC outer cover offers excellent flexibility and reduced "memory", making it easy to roll up and unroll without knots.
-
Esoteric Series Construction: Belonging to Proel's high-end range, designed to withstand the demands of professional tours and recording studios.
Product benefits
For the professional user, the greatest benefit of the PROEL ESO230LU3 is peace of mind. Knowing that the connection between their equipment uses Neutrik connectors eliminates worries about mechanical failures or crackling noises in the middle of a performance. The cable's balanced architecture ensures that when connecting compatible equipment (such as audio interfaces to monitors), the system will actively cancel induced noise along the cable's path, resulting in absolute silence when not playing music. Furthermore, its long-term durability makes it a smart investment compared to inexpensive cables that require frequent replacement.
Use cases
-
Studio Monitors: Ideal connection from the audio interface or mixing console to the active monitors, guaranteeing a noise-free signal.
-
Balanced Instruments: Perfect for professional keyboards, synthesizers, and drum machines that have balanced TRS outputs.
-
Effects Processors: Interconnection of equipment in studio or live racks (compressors, equalizers) using patchbays.
-
Headphone Amplification: Can be used as an extension cable for stereo headphone signals or mix sends.
Frequently Asked Questions
-
Is this cable suitable for connecting an electric guitar to an amplifier?
Technically, it can transmit the signal, but guitars typically use "mono" (TS) cables. This is a "stereo/balanced" (TRS) cable. For guitars, a dedicated TS instrument cable is recommended; although this one will work without mechanical issues, the balanced functionality won't be fully utilized on a standard guitar.
-
Is it a stereo or mono cable?
It's a TRS (Tip-Ring-Sleeve) cable. This means it can function as a stereo cable (left/right in a single cable) or as a balanced mono cable. The function depends on the equipment you connect.
-
Are the connectors repairable?
Yes, Neutrik NP3X connectors are completely detachable and repairable, which extends the product's lifespan indefinitely.
-
What exact model of cable do you use?
This assembly uses the Proel HPC250 bulk cable from the Esoteric series.
Project description
Professional 3-meter assembled balanced audio cable, model PROEL ESO230LU3. The core cable is the Esoteric HPC250, made of high-purity oxygen-free copper (OFC) conductors with a flexible black PVC jacket. The ends are terminated with genuine Neutrik NP3X connectors (6.3mm TRS male jacks) featuring nickel-plated metal housings, silver contacts, and a mandrel-type cable retention system. This configuration is suitable for transmitting balanced line-level or stereo signals.
