REL AirShip II Wireless Transmitter

REL AirShip II Wireless Transmitter for REL Subwoofers

Cut the cable without cutting the performance. The REL AirShip II Wireless Transmitter is REL’s next-generation wireless system designed to deliver the speed, depth and musicality that serious audio systems demand. Built for selected REL subwoofers, AirShip II gives you the freedom to position your subwoofer exactly where it performs best, without being limited by cable runs across your room.

Whether you’re building a dedicated hi-fi system or a full home cinema setup, AirShip II preserves the character, timing and energy of your bass with remarkable precision.

A New Standard in Wireless Subwoofer Performance

Wireless audio has often meant compromise—reduced detail, added noise or softened dynamics. AirShip II changes that.

At the heart of the system is a newly upgraded Texas Instruments DAC/ADC chipset, engineered to dramatically improve signal quality. By lowering the wireless noise floor by 12dB, AirShip II creates a cleaner signal path, allowing more detail to come through.

The result is bass that feels tighter, faster and more natural.

Instead of sounding compressed or blurred, low frequencies retain their shape and texture, helping music and film soundtracks feel more lifelike.

This is especially noticeable in:

• Fast bass guitar passages
• Drum transients
• Low-frequency cinematic effects
• Layered orchestral recordings

It’s wireless, but it doesn’t sound like wireless.

Full Bandwidth Transmission Without the Usual Limitations

AirShip II is built to carry a full-range signal over distance while maintaining clarity and timing.

Even over 40 to 60 feet, the signal remains stable and highly detailed, making it ideal for larger listening rooms, media rooms or installations where cable routing would be difficult or impractical.

This gives you more flexibility to position your REL subwoofer in the part of the room where bass performs best—not just where cables can reach.

That freedom can make a huge difference to bass response.

Better placement often means:

• Smoother room integration
• Improved low-frequency balance
• Better soundstage depth
• Stronger impact without boominess

Multiple Connection Options for Greater System Compatibility

One of AirShip II’s biggest strengths is its flexibility.

Unlike many wireless systems that offer only one connection method, AirShip II supports multiple input types to suit different setups.

High-Level Input

REL’s signature high-level connection allows the subwoofer to receive the exact same signal as your main speakers.

This helps preserve the tonal character of your amplifier and speakers, creating bass that blends naturally into the rest of the system rather than sounding separate.

Perfect for:

• Stereo amplifiers
• Integrated amplifiers
• Power amplifiers

Low-Level Input

Ideal for modern systems that require line-level integration, including active speakers and certain preamp setups.

This offers straightforward system matching while maintaining excellent performance.

.1/LFE RCA Input

For AV receivers and cinema systems, the dedicated LFE channel handles low-frequency effects with authority and precision.

This ensures movie soundtracks deliver the intended impact.

Balanced XLR LFE Input

For higher-end theatre systems, balanced XLR connectivity offers improved signal integrity and lower interference over longer cable runs.

A strong option for premium AV processors.

Simultaneous Music and Home Cinema Performance

One of AirShip II’s standout features is its ability to run High-Level and .1/LFE channels at the same time.

That means you don’t need to switch cables or settings depending on what you’re listening to.

For music:
High-Level connection preserves the natural flow and character of your stereo system.

For movies:
The dedicated .1/LFE channel handles explosive effects, deep impact and cinematic low-end energy.

Together, they create REL’s Theatre Reference performance, combining musical bass integration with full-scale cinematic power.

This dual-path wireless setup gives you the best of both worlds in one system.

Faster Signal Delivery for Better Timing

Bass timing matters.

If bass arrives late—even slightly—it can make a system feel disconnected.

AirShip II is engineered for speed, helping low frequencies stay locked in with your speakers.

That means:

• Better rhythm in music
• More accurate attack and decay
• Greater realism in movie effects
• Cleaner transitions between frequencies

The difference is easy to hear in fast-paced music and action-heavy films.

Quick Pairing, Simple Setup

REL designed AirShip II to be easy to live with.

Setup is simple:

1. Connect the transmitter and receiver
2. Power both on
3. Press the pairing button

In most cases, pairing completes in under five seconds.

No complicated menus. No app. No unnecessary setup process.

Just connect and listen.

More Freedom for Better Room Design

Subwoofer placement can dramatically affect performance, but cable routing often forces compromises.

AirShip II removes that limitation.

You can place your REL where it sounds best, not where it’s easiest to wire.

That gives you more flexibility for:

• Cleaner room layouts
• Better furniture placement
• Reduced visible cabling
• Improved listening results

It’s a practical upgrade as much as a performance upgrade.

AirShip II is designed for selected REL models including:

• REL No.32
• REL No.31
• REL 212/SX
• REL Carbon Special
• REL S/812
