PROEL BOX804S - 12-Channel Modular Stage Box (8 Inputs / 4 Returns) with Multipin Connector
Optimize audio management for your live events and studio setups with the Proel BOX804S , a high-end stage box designed for professionals who demand order, speed, and reliability. This signal distribution system acts as the central hub on stage, allowing you to consolidate multiple microphone lines and monitor returns into a single compact and robust unit. Unlike traditional audio cables, the BOX804S stands out for its modular design, incorporating a CMIL37MP multipin connector that facilitates complete disconnection of the main cabling, drastically speeding up setup and teardown times (load-in/load-out).
Built to withstand the rigors of touring, the chassis is constructed from robust metal with a black epoxy paint finish, ensuring superior protection against bumps and scratches. Its hybrid configuration of 8 XLR inputs and 4 XLR outputs/returns makes it ideal for stage subgroups, such as fully miking a drum kit, horn sections, or choirs, allowing you to send the monitor mix directly from the same point without the need for additional cable runs.
The engineering behind the CMIL37MP multipin connector ensures clean and reliable signal transmission. Thanks to its bayonet locking system, the connection between the connector and the main cable is secure during performance, preventing accidental disconnections. This device is more than just an accessory; it's an investment in your sound system's technical infrastructure, eliminating cable clutter and reducing electromagnetic interference thanks to its excellent shielding and grounding design.
Main features
-
Versatile 12-channel configuration: It has 8 female panel XLR connectors for inputs (microphones, DI boxes) and 4 male panel XLR connectors for returns (sends to monitors, in-ears or PA).
-
Multipin Modular Connection: Equipped with a 37-pin CMIL37MP male chassis connector, compatible with standard CMIL series multipair cables, allowing the cable box to be separated for easier transport.
-
"Road-Ready" Construction: Heavy-duty metal enclosure with epoxy powder coating, designed to withstand trampling and daily wear and tear on stages.
-
High-Quality Connectors: The panel-mount XLR ports feature high-conductivity contacts and secure locking mechanisms to ensure no signal loss.
-
Clear Screen Printing: High-visibility channel numbering for easy quick patching in low-light conditions.
Benefits for the user
-
Ultra-fast assembly: By being able to disconnect the main hose, you can leave the pre-wired box in the drum set or keyboard rack, and simply connect the multipin upon arrival at the event.
-
Order and safety on stage: Drastically reduces the number of individual cables crossing the stage, minimizing tripping hazards and improving the visual aesthetics of the show.
-
Easy maintenance: As it is a modular system, if the main cable is damaged, it can be replaced or repaired without having to discard or open the entire stage box.
-
Flexibility of use: Perfect for use as a "Sub-Snake" (sub-hose) on large stages to group specific zones, or as a main system in small clubs and theaters.
Use cases
-
Drum Microphones: Use all 8 channels for kick drum, snare, toms and cymbals, and use all 4 returns to send the monitor mix to the drummer (shaker, in-ears).
-
Festival Stages: Ideal as a zone distribution box (Stage Left / Stage Right) for connecting backline and amplifiers.
-
Fixed Installations: Theatres or conference rooms where a discreet floor connection box is required that can be disconnected and stored when not in use.
-
Recording Studios: Extension of inputs from the control room to the recording room (Live Room) to capture full bands.
Frequently Asked Questions
-
Does the multipair cable come included with the junction box?
No, this product is the stage box unit only. It requires a compatible female aerial cable (37-pin CMIL series) to operate.
-
Are the connections balanced?
Yes, both the XLR inputs and outputs are configured to carry a balanced audio signal, which protects the sound from interference and noise over long runs.
-
Can I use the return channels (XLR Male) as inputs?
Technically, it's possible using gender adapters (inverters), but these are designed for sending signals from the mixing console to the stage. It's recommended to adhere to the standard signal flow to avoid confusion.
-
Is it compatible with Phantom power (+48V)?
Yes, the internal wiring and connectors perfectly support the transmission of phantom power from the mixing console to the condenser microphones connected to the junction box.
Project description
Modular passive stage box constructed from a metal chassis with a high-resistance epoxy finish. The system offers a total capacity of 12 analog audio channels, distributed across 8 inputs via 3-pole female XLR panel connectors and 4 outputs/returns via 3-pole male XLR panel connectors. Connection to the main cable system is made through a 37-pin CMIL37MP male circular multi-pin chassis connector with a bayonet locking system. The device allows for complete disconnection of the multi-pair cabling for easier transport and storage. Compact dimensions and highly visible numerical markings on the front panel.
