PROEL EBN3208 - Professional Stage Box with 40 Channels (32 IN / 8 OUT) with 30 Meter Hose
The PROEL EBN3208 is a high-end audio distribution solution designed to facilitate connections on large stages. Part of Proel's acclaimed EBN series, this cable and junction box system is distinguished by its robust construction and technical reliability, making it an industry standard for sound engineers and rental companies that require flawless signal transmission.
With a massive 32 inputs and 8 outputs , this device allows you to mic up entire bands, orchestras, or large theatrical productions, sending all signals to the mixing console and managing up to 8 returns for monitors or the main PA, all through a single 30-meter multicore cable. Its design incorporates printed circuit board (PCB) technology, which not only improves the reliability of the soldering but also significantly reduces the weight and size of the chassis compared to traditional hand-wired boxes.
Audio quality is guaranteed thanks to the use of CMF series multicore cable with separate grounding, ensuring superior shielding against electromagnetic interference and parasitic noise, crucial in noisy live environments or demanding recording studios.
Main features
-
40-channel capacity: Logical distribution of 32 sends (mic/line inputs) and 8 returns, ideal for complex stage setups.
-
High-reliability PCB construction: The chassis connectors are mounted on professional printed circuits, eliminating the risk of loose internal wires and reducing the physical size of the enclosure.
-
High-quality connectors: The box features XLR connectors with gold-plated contacts for maximum conductivity. The cable terminates in PROEL XLRPRO series metal aerial connectors.
-
Indestructible chassis: Metal case with epoxy powder finish, resistant to shocks, scratches and the typical wear and tear of tours and intensive use.
-
Multicore CMF Cable: Flexible and durable 30-meter cable, designed to withstand twisting and stepping, maintaining signal integrity.
-
Clear numbering: Both the box panel and the aerial connectors are clearly numbered for quick and error-free identification during assembly.
Product benefits
The PROEL EBN3208 offers a clear competitive advantage in terms of durability and signal purity . By using gold-plated contacts, long-term oxidation is minimized, ensuring that audio quality remains crystal clear year after year. For assembly technicians, the reduced weight (thanks to the PCB design) facilitates transport and handling without sacrificing the robustness required for on-the-road work.
Furthermore, the chassis' epoxy finish protects the equipment's aesthetic and functional investment, keeping it presentable even after hundreds of gigs. Ground separation in the multicore cable is a critical technical benefit, as it drastically reduces the risk of hum and crosstalk between channels, enabling cleaner, more professional mixes.
Use cases
-
Concerts and Festivals: Ideal for main stages where it is necessary to mic up full drum kits, percussion, amplifiers and vocals, while managing multiple mixes of in-ear monitors or wedges.
-
Installations in Theatres and Auditoriums: Perfect as a fixed connection point on the stage that connects to the control booth 30 meters away.
-
Outdoor Recording and Broadcast: Mobile units that need to quickly deploy multiple audio lines from the scene of the action to the production truck.
-
Churches and Places of Worship: Simplifies the wiring from the altar or stage to the mixing console, eliminating the tangle of individual cables and improving the visual aesthetics.
Frequently Asked Questions
-
Are the connectors compatible with Phantom power (+48V)?
Yes, absolutely. The balanced XLR cabling and connectors support phantom power for condenser microphones and active DI boxes without any issues.
-
How are the channels identified on the side of the hose?
Each XLR aerial connector has a clear numerical ring or label that corresponds exactly to the number on the stage box, making it easy to "patch" on the mixing console.
-
Is it possible to repair the junction box if a connector is damaged?
Yes, although the construction is on PCB for greater reliability, the chassis is accessible for qualified technical service in case a repair or maintenance is needed.
-
What is the difference between inputs and outputs?
The 32 "Inputs" are female XLR connectors on the box (for connecting microphones) and male connectors on the cable (for the mixer). The 8 "Outputs" are male XLR connectors on the box (for connecting speakers/monitors) and female connectors on the cable (for receiving the signal from the mixer).
