Description
Compact IP67 weatherproof wired remote controller engineered for auxiliary MediaMaster source unit control in marine and off-road applications.
Product Overview
The JL Audio MMR-20-BE is a wired remote controller that delivers essential auxiliary control functionality for MediaMaster source units in tight-space installations. Featuring a compact 60mm × 60mm footprint with simple one-hole mounting design, the MMR-20-BE places frequently used MediaMaster functions—source selection, volume adjustment, and track navigation—within easy reach at helm stations, cockpit areas, tower positions, or off-road vehicle mounting locations. The IP67 weatherproof rating (when properly installed) provides comprehensive protection against dust ingress and temporary water immersion, making it ideal for Australian coastal boating, offshore fishing, beach-launched vessels, and extreme 4WD applications where weather exposure demands robust construction.
Large backlit controls and LED source indicators ensure easy identification day or night, with brightness settings adjustable through the host MediaMaster source unit. The intuitive button layout enables one-handed operation without requiring visual attention—critical for helm concentration during navigation or off-road driving where focus on terrain matters. Connection flexibility allows up to three MMR-20-BE remote controllers per MediaMaster source unit, with each remote mountable up to 22.8 metres (75 feet) from the host unit. This enables multiple control points across vessels or vehicles: helm, flybridge, and cockpit stations on boats, or driver, passenger, and rear cargo locations in 4WD tourers, all controlling a single MediaMaster source unit.

Features & Benefits
IP67 Weatherproof Construction
When properly installed, the IP67-rated chassis provides protection against complete dust ingress and temporary water immersion (up to 1 metre for 30 minutes). The robust weatherproof design handles deck washdowns, heavy rain, salt spray, bilge moisture, water crossings, and the demanding conditions of Australian coastal boating and extreme off-road adventures. Suitable for exposed helm stations, centre console boats, tower positions on fishing vessels, or exterior 4WD mounting locations where lesser remotes fail under environmental stress.
Compact One-Hole Mounting Design
The 60mm × 60mm footprint and simple one-hole installation enable mounting in locations where traditional remotes won't fit. Perfect for crowded helm stations with limited panel space, tower positions requiring unobtrusive controls, or off-road vehicle dashboards already populated with gauges and switches. The small size doesn't compromise functionality—all essential MediaMaster controls remain accessible in the compact form factor. Ideal for boats, utes, 4WDs, and recreational vehicles with space constraints.
Large Backlit Controls for Easy Operation
Oversized buttons with backlighting ensure reliable operation in challenging conditions. Use the controls wearing gloves during winter fishing, operate one-handed while maintaining helm control underway, or adjust audio without diverting visual attention from navigation or off-road terrain. The intuitive layout reduces the learning curve—crew members, passengers, or family members can operate the remote without extensive instruction, unlike complex touchscreen interfaces requiring visual confirmation.
LED Source Indicators
Visual feedback via LED indicators confirms source selection, providing at-a-glance confirmation of active audio input. Essential for systems with multiple sources (AM/FM, USB, Bluetooth, auxiliary) where auditory confirmation is difficult in noisy marine or off-road environments with wind, engine, and wave noise. The LED indicators work in conjunction with brightness controls adjustable through the MediaMaster source unit, ensuring visibility without causing night vision disruption during evening navigation.
Extended Connection Range
Each MMR-20-BE connects up to 22.8 metres (75 feet) from the host MediaMaster source unit, enabling flexible installation across large vessels or extended vehicle configurations. Perfect for flybridge control on sportfishing boats where the main source unit is in the cabin, tower positions on offshore vessels, rear cargo entertainment in extended 4WDs, or caravan installations where the source unit is in the main cabin but remote control is needed in bedroom or outdoor entertainment zones.
Multiple Remote Support
Install up to three MMR-20-BE remotes per MediaMaster source unit for comprehensive multi-location control. Configure helm, flybridge, and cockpit control on boats, or driver, passenger, and rear cargo control in touring vehicles. Each remote operates independently—change tracks from the flybridge while passengers adjust volume in the cockpit, or front seat passengers control source selection while rear passengers handle volume. Eliminates disputes over audio control and provides convenience across large spaces.
Simple Wired Reliability
Unlike wireless remotes susceptible to interference, battery depletion, or pairing issues, the wired MMR-20-BE provides reliable operation without connectivity concerns. No batteries to replace, no Bluetooth pairing procedures, no signal dropout in electrically noisy environments. The hardwired connection ensures consistent operation regardless of marine electronics interference, engine electrical noise, or crowded wireless spectrum in marina environments with dozens of active Bluetooth devices.

Caution: The MMR-20-BE requires a compatible MediaMaster source unit to function. It is NOT a standalone head unit. Ensure your vessel or vehicle has or will have a MediaMaster source unit installed. The MMR-20-BE only controls MediaMaster units—it cannot control other marine head unit brands or models.
Frequently Asked Questions
Can I use the MMR-20-BE without a MediaMaster source unit?
No. The MMR-20-BE is a remote controller, not a standalone head unit. It requires a compatible JL Audio MediaMaster source unit (MM50, MM100s, or other MediaMaster models) to function. The remote provides auxiliary control of the MediaMaster but cannot operate independently.
What's the difference between IP67 and IP66 ratings?
IP67 provides protection against temporary water immersion (up to 1 metre for 30 minutes) in addition to dust ingress prevention. IP66 (like the MMR-40) protects against powerful water jets and dust but not immersion. The MMR-20-BE's IP67 rating offers superior water protection for applications with potential submersion risk like deck-level mounting, water crossings, or extreme weather exposure.
How many MMR-20-BE remotes can I connect to one MediaMaster?
Up to three MMR-20-BE remotes per MediaMaster source unit. This enables comprehensive multi-location control: helm, flybridge, and cockpit on boats, or driver, passenger, and rear cargo areas in vehicles. Each remote operates independently with full control functionality.
What's the maximum distance I can mount the remote from the source unit?
Each MMR-20-BE can be connected up to 22.8 metres (75 feet) from the host MediaMaster source unit. This extended range accommodates large vessels with flybridge or tower mounting, extended 4WD configurations, or caravan setups where the source unit is in the main cabin but remote control is needed in distant zones.
What controls are available on the MMR-20-BE?
While specific button functions aren't detailed in available documentation, typical functionality includes source selection, volume adjustment, track navigation (next/previous), and possibly play/pause control. The "frequently used functions" description suggests core MediaMaster controls without advanced menu access available on the full-featured MMR-40 with LCD display. Consult JL Audio documentation for complete button mapping.
