Soundtube WLL-TR-1P-II Tri-band Uncompressed Wireless WLL-TX1 Trans. WLL-RX1P Rec. Sys.

SoundTube WLL-TR-1P-II Tri-Band Uncompressed Wireless Audio System

The SoundTube WLL-TR-1P-II is a complete wireless audio transmission system that pairs the WLL-TX1 transmitter with the WLL-RX1P receiver — a 2-channel, 50-watt-per-channel Class D amplifier — to deliver uncompressed stereo audio over 2.4 GHz tri-band RF with sub-20ms latency. Designed for professional commercial AV installations, the system eliminates the cost and complexity of running speaker wire across large distances while maintaining the full-fidelity audio performance that hospitality, retail, and corporate environments require. The transmitter accepts USB, stereo mini, and 1/4" balanced inputs, covering virtually every source device encountered in modern AV installations. With a full-power indoor range of 150 feet and line-of-sight range of 210 feet, the WLL-TR-1P-II is the correct specification for multi-zone wireless audio in rooms, across atriums, or between buildings in campus environments.

Description

The WLL-TX1 transmitter unit uses 2.4 GHz RF technology with tri-band frequency hopping across 3 channels — alternating between bands preemptively to counteract interference before it occurs, keeping the audio signal continuous and latency below 20ms. A High/Low power selector switch on the transmitter limits RF range where needed, providing flexibility in dense RF environments or installations where signal containment to a specific zone is required. The WLL-RX1P receiver incorporates a 2-channel 50W/ch Class D amplifier capable of directly powering up to two speaker loads, with push-on Phoenix connector and 1/4" output options. The receiver also provides a stereo line output for connecting to auxiliary audio components, and a local audio input via stereo mini that automatically mutes the wireless signal when a local source is connected. System scalability is a key design principle: up to five additional receivers can accompany a single transmitter for a total of six receivers in one wireless zone, and two additional transmitters can operate on separate frequencies to create up to three independent zones with 18 total receiver units. Dynamic range of 90 dB and flat frequency response from 20 Hz to 20 kHz confirm that the WLL-TR-1P-II delivers full-fidelity, uncompressed audio that is indistinguishable from wired performance. The powder-coated metal housing provides the build quality required for permanent commercial installation in equipment racks or above-ceiling deployments.

Key Features

• Uncompressed Stereo Wireless Transmission — Full-fidelity 20 Hz–20 kHz audio over 2.4 GHz with 90 dB dynamic range, eliminating the sound quality compromises of compressed wireless systems.
• Tri-Band Frequency Hopping — Three RF channels, each alternating across 3 bands, preemptively counteracts interference for sub-20ms continuous audio delivery in complex RF environments.
• Integrated 50W/ch Class D Amplifier — The WLL-RX1P receiver directly powers up to two speakers per unit, reducing rack space and hardware costs versus separate amplifier deployments.
• Multiple Source Inputs — USB, stereo mini, and 1/4" balanced inputs at the transmitter cover virtually every commercial AV source device without additional adapters.
• Scalable Multi-Zone Architecture — One transmitter supports up to 6 receivers; three transmitters on separate frequencies support up to 18 receivers across independent audio zones.
• 150 ft Indoor / 210 ft Line-of-Sight Range — Full-power operating range covers large open-plan spaces, atriums, and between-building campus deployments without repeaters.
• Local Audio Input with Auto-Mute — Receiver stereo mini input mutes wireless signal when local source is connected, enabling hybrid wired/wireless installations at each zone.
• Rack-Mountable, Powder-Coated Metal Housing — Professional form factor with included rack mount adapters for permanent AV infrastructure deployments.

Typical Applications

• Hotel ballrooms and multi-function event spaces requiring wireless audio zones without ceiling wire runs
• Restaurant and bar background music systems where running new wiring is cost-prohibitive
• Corporate campus multi-building audio distribution systems
• Retail environments requiring flexible zone audio without permanent infrastructure changes
• Houses of worship with large sanctuaries or multi-room audio distribution needs
• Museum and gallery installations where cable concealment is an aesthetic requirement

Technical Specifications

Frequently Asked Questions

How many receivers can one WLL-TX1 transmitter support?

A single WLL-TX1 transmitter supports up to 6 WLL-RX1P receivers (1 included + 5 additional). Three transmitters on separate frequencies can support up to 18 receivers across independent zones.

Does the system use audio compression?

No. The WLL-TR-1P-II transmits uncompressed stereo audio with 90 dB dynamic range and flat 20 Hz–20 kHz frequency response, preserving full audio fidelity from source to speaker.

What is the wireless range in a typical hotel ballroom?

At full power, the system achieves 150 feet indoors and 210 feet line-of-sight. Range may vary based on RF environment, obstructions, and interference from other 2.4 GHz devices. The low-power setting limits range to 50 ft indoors when zone containment is required.

Can the WLL-RX1P receiver power loudspeakers directly?

Yes. The WLL-RX1P contains a 2-channel 50W/ch Class D amplifier with Phoenix connector and 1/4" outputs, allowing it to directly drive up to two passive speaker loads without a separate amplifier.

What happens if the wireless signal is interrupted?

The tri-band frequency hopping system preemptively alternates between 3 bands on each of 3 channels to counteract interference before it causes dropouts, maintaining sub-20ms latency throughout the transmission.

Is the WLL-TR-1P-II rack-mountable?

Yes. Rack mount adapters are included in the package. Additional rack mount adaptor (AC-WLL-RMA) and power supply options are available as optional accessories.

What certifications does the WLL-TR-1P-II hold?

The system is CCC, CE, FCC, RoHS, and UL60065 certified, covering commercial AV installation compliance in North America, Europe, and China.
