JL Audio JLA-010-03134-00 MMR-5N2K Volume Controller

JL Audio JLA-010-03134-00 MMR-5N2K Volume Controller - NMEA 2000 Wired Remote for MediaMaster Source Units

IPX7 weatherproof NMEA 2000 wired volume controller providing auxiliary remote control for MediaMaster marine source units throughout the vessel.

Product Overview

The JL Audio MMR-5N2K Volume Controller (JLA-010-03134-00) provides convenient auxiliary volume control for MediaMaster MM55 and MM105 source units through NMEA 2000 network connectivity. This weatherproof wired remote enables crew and passengers to adjust audio volume from distant locations throughout the vessel without accessing the main head unit, ideal for cockpit seating areas, swim platforms, cabin spaces, or tower positions. Engineered specifically for harsh marine environments, the IPX7 weatherproof rating ensures complete protection against water immersion up to 1 meter depth for 30 minutes, making it suitable for fully exposed installations in spray-prone areas. The compact design (2.35" x 2.35" x 2.04") fits tight mounting locations while the straightforward rotary control provides intuitive volume adjustment. The MMR-5N2K connects to MediaMaster source units through two methods: direct integration with the vessel's existing NMEA 2000 network using standard marine network cables and connectors, or direct connection to a single MediaMaster unit using optional MMC-PN2K powered network cables that simulate an isolated NMEA 2000 network. The NMEA 2000 Micro-C connector ensures reliable marine-grade connection integrity. With 2 LEN (100mA) load equivalency, the controller integrates seamlessly into existing NMEA 2000 networks without exceeding power budgets. The professional installation includes mounting hardware for secure attachment to bulkheads, consoles, or dash panels throughout the vessel.

Features & Benefits

IPX7 weatherproof rating provides complete protection against water immersion and dust intrusion, enabling installation in fully exposed locations including swim platforms, cockpit areas, tower positions, or anywhere crew needs volume control access. NMEA 2000 network connectivity integrates with vessel's existing marine electronics network, allowing multiple MMR-5N2K controllers throughout the boat all controlling the same MediaMaster source unit via standard marine networking infrastructure. Flexible connection options support either integration with vessel's NMEA 2000 backbone using standard marine network cables (drop cables, T-connectors, terminators) or direct point-to-point connection to a single MediaMaster using optional MMC-PN2K powered network cables for vessels without NMEA 2000 networks. Compact dimensions (60mm x 60mm x 52mm) fit tight mounting locations on consoles, bulkheads, dash panels, or tower structures where space is limited. Simple rotary control design provides intuitive volume adjustment that's easy to operate while underway, wearing gloves, or in low-light conditions. Low power consumption (2 LEN / 100mA) minimizes electrical load on NMEA 2000 network, allowing multiple controllers without exceeding network power budgets. Micro-C connector provides secure, marine-grade connection with positive locking mechanism that prevents accidental disconnection from vibration or cable movement. Universal compatibility with both MediaMaster MM55 and MM105 source units enables consistent control regardless of which source unit is installed. Professional appearance matches marine electronics aesthetics with clean, purposeful design appropriate for premium boat installations. Included mounting hardware ensures secure installation resistant to marine vibration and environmental factors.

Frequently Asked Questions

Do I need an existing NMEA 2000 network to use the MMR-5N2K controller? No, you have two options: (1) If your vessel already has a NMEA 2000 network for marine electronics, you can integrate the MMR-5N2K using standard NMEA 2000 cables and connectors (drop cable, T-connector at backbone). (2) If you don't have a NMEA 2000 network, purchase optional MMC-PN2K powered network cables that create a direct point-to-point connection between the controller and MediaMaster, simulating an isolated NMEA 2000 network without requiring full infrastructure. This makes the controller accessible to vessels of all sizes regardless of existing electronics.

Can I install multiple MMR-5N2K controllers to control the same MediaMaster? Yes, multiple MMR-5N2K controllers can be installed at different locations throughout the vessel, all controlling the same MediaMaster source unit. When connected via NMEA 2000 network, simply add additional drop cables and T-connectors for each controller location. All controllers adjust the same system volume simultaneously. This is perfect for larger boats where crew needs volume control access from helm, cockpit, swim platform, cabin, and tower positions. Just ensure total LEN load doesn't exceed your NMEA 2000 network power budget (each controller uses 2 LEN / 100mA).

Where should I mount the MMR-5N2K for best accessibility? Common locations include cockpit seating areas where passengers need volume control without accessing the helm, swim platforms for watersports activities, tower positions for tower speaker control, cabin entry areas for interior audio adjustment, or co-pilot position on center console boats. Choose locations that provide easy reach from typical seating or standing positions, with adequate protection from direct water spray when possible (though IPX7 rating handles full exposure). Ensure cable routing path exists from mounting location to NMEA 2000 network or MediaMaster location.

What's the difference between using NMEA 2000 network versus MMC-PN2K direct connection? NMEA 2000 network integration uses standard marine networking infrastructure with backbone cable, drop cables, T-connectors, and terminators—ideal for vessels with existing NMEA 2000 systems where multiple controllers or other NMEA devices share the network. MMC-PN2K direct connection uses dedicated powered cables running point-to-point from controller to MediaMaster—ideal for vessels without NMEA 2000 networks where simple remote volume control is the only requirement. NMEA network offers more flexibility and expandability; direct connection offers simplicity for single-controller installations.

Will the MMR-5N2K work with my non-JL Audio head unit if it has NMEA 2000? No, the MMR-5N2K is specifically designed for JL Audio MediaMaster MM55 and MM105 source units only. While it uses standard NMEA 2000 physical connections (Micro-C connectors), the communication protocol is proprietary to JL Audio MediaMaster systems. It will not control volume on other brands' head units even if they support NMEA 2000 networking. For MediaMaster systems, the MMR-5N2K provides seamless integration with guaranteed compatibility and proper functionality.
