Soundtube WLL-RX1P-II Tri-band Uncompressed Wireless Receiver

The SoundTube WLL-RX1P-II is a tri-band uncompressed wireless receiver unit that integrates a built-in 2-channel Class D amplifier rated at 50 W per channel, enabling a complete wireless distributed speaker system without running new speaker wire. Each receiver pairs with a SoundTube wireless transmitter and can drive up to two standard passive speakers directly, making it an efficient solution for adding audio zones to existing structures where cable runs are impractical. Up to six receiver units can operate with a single transmitter, and up to three transmitters can operate simultaneously on separate frequencies for a maximum of 18 wireless receiver units per installation.

Available from Creation Networks, the WLL-RX1P-II operates on three RF channels, each automatically alternating across three sub-bands to preemptively counteract interference and maintain a signal latency of less than 20 ms — transparent for music and paging applications. Output connections include push-on Phoenix connectors and 1/4-inch jacks for speaker loads, plus a stereo line output for downstream audio components. A stereo mini-jack local audio input mutes the wireless signal automatically when a local source is connected. The compact 1U-compatible chassis includes rack mount adapters, antenna, and power supply in the box. FCC, CE, CCC, RoHS, and UL 60065 certified.

Key Features

• Built-In 2-Channel 50W/ch Class D Amplifier — Drives up to two passive speakers per unit without additional amplification hardware; reduces installation cost and complexity.
• Tri-Band Frequency Hopping — Three RF channels each alternate across three sub-bands, proactively avoiding interference and maintaining latency below 20 ms.
• Scalable Wireless Network — Up to 6 receivers per transmitter; up to 3 transmitters (18 receivers total) in a single installation for large multi-zone deployments.
• Uncompressed Audio Transmission — Lossless signal path preserves audio quality equivalent to wired infrastructure for music and voice paging.
• Multiple Output Options — Phoenix push-on connectors, 1/4-inch speaker outputs, and stereo line output for flexible system integration.
• Local Audio Override — Stereo mini-jack input automatically mutes the wireless feed when a local source is plugged in; useful for zone-specific announcements.
• Rack-Mountable Form Factor — 1U-compatible chassis with included rack mount adapters fits standard AV equipment racks for clean installations.
• FCC, CE, CCC, UL 60065 Certified — Compliant with international wireless and electrical safety standards for commercial installation.

Typical Applications

The WLL-RX1P-II solves audio distribution challenges in retrofit and historic environments: adding background music zones to restaurants and retail spaces without running new wire, expanding hotel room audio to guest areas with structural limitations, providing temporary event audio at convention venues, distributing audio across multi-building campus environments, and enabling background music in environments where conduit installation is cost-prohibitive.

Technical Specifications

Frequently Asked Questions

Does the WLL-RX1P-II require a separate amplifier?

No. The integrated 2-channel Class D amplifier drives up to two passive speakers directly from the receiver unit. No external amplifier is needed in the speaker zone.

How many receivers can one transmitter support?

A single transmitter supports up to 6 WLL-RX1P-II receiver units simultaneously. Adding two more transmitters on separate frequencies allows up to 18 total receiver units across an installation.

Is the audio transmission lossless or compressed?

The WLL system transmits uncompressed audio, preserving the full signal quality of the source material — equivalent to wired audio distribution for music and voice applications.

What is the wireless latency?

Latency is less than 20 ms, which is imperceptible for background music and paging. For applications requiring video sync, confirm latency tolerance with the video playback system.

Can a local audio source override the wireless feed?

Yes. Plugging a source into the stereo mini-jack local input automatically mutes the wireless signal at that receiver, enabling zone-specific announcements or override audio without affecting other receiver zones.

What does the rack mount adapter enable?

The included adapter fits the WLL-RX1P-II into standard 1U rack spaces for installations where the receiver needs to be rack-mounted alongside other AV equipment rather than surface-mounted in the speaker zone.
