WTSD Audio/Power & Control Interface

Ideal Use Cases

The AtlasIED WTSD-PWHUB is designed as an audio, power, and control interface for AtlasIED WTSD wall plate mixers. It is suited to systems that require a dedicated connection between WTSD wall plate mixer hardware and a balanced line-level audio path. Its proprietary RJ45 8-wire bus provides the specified input connection for the WTSD system.

The interface also provides an emergency audio mute for fire systems. This makes it appropriate for WTSD installations where the audio system must support emergency muting as part of the system design. Its compact dimensions allow it to fit into installations where equipment space is limited.

Why Choose This Model

The WTSD-PWHUB combines audio, power, and control interfacing in a model specifically identified for AtlasIED WTSD wall plate mixers. Its output is balanced line level, with a published output impedance of 300 ohms balanced and 150 ohms unbalanced. Level control ranges from 0 to +6 dB and includes a defined 0 dB mark, providing a clear reference when setting the output level.

For installations that require emergency system coordination, the included emergency audio mute capability is a central reason to select this interface. The unit is also covered by a 36-month warranty from the date of purchase.

Installation and Integration

The input uses an RJ45 proprietary 8-wire bus. Because the connection is proprietary, the WTSD-PWHUB is intended for integration with AtlasIED WTSD wall plate mixers rather than being presented as a general-purpose RJ45 audio interface. The output is specified as balanced line level, enabling the interface to provide the WTSD system’s audio output to compatible downstream equipment.

Output adjustment is available from 0 to +6 dB, with the 0 dB position marked for reference. The enclosure measures 4 inches wide, 1.5 inches high, and 2.75 inches deep, corresponding to 101 × 39 × 70 mm. The unit weighs 0.375 lb, or 0.17 kg, while its listed shipping weight is 0.625 lb, or 0.28 kg.

The specified operating temperature range is 14 to 104 degrees Fahrenheit, or -10 to 40 degrees Celsius. Installation planning should account for this range as well as the proprietary bus requirement and the stated line-level output characteristics.

Performance Highlights

The WTSD-PWHUB has a specified frequency response of 20 Hz to 20 kHz within ±1 dB. Total harmonic distortion is rated at 0.06% at 1 kHz. These published measurements define its audio operating range and distortion performance for WTSD wall plate mixer applications.

The balanced line-level output has a 300-ohm balanced output impedance, with 150 ohms specified for unbalanced operation. Its adjustable level control covers 0 to +6 dB, allowing the output to be set at the marked 0 dB reference or increased within the available range. A refresh rate of 20 Hz is also listed in the technical specifications.

What Makes It Different

This model is differentiated by its dedicated role within the AtlasIED WTSD wall plate mixer system. It brings the system’s audio, power, and control interfacing into one compact component while providing a balanced line-level output. The proprietary RJ45 8-wire bus identifies the WTSD-PWHUB as a purpose-specific interface rather than a standard network device.

Its emergency audio mute function for fire systems adds a clearly defined system capability. Combined with the adjustable output level, marked 0 dB position, published impedance values, and compact enclosure, the interface provides the documented connection and control features required for its WTSD application.

Final Assessment

The AtlasIED WTSD-PWHUB is a focused interface for AtlasIED WTSD wall plate mixers. It is a strong match when the installation calls for the proprietary 8-wire bus, balanced line-level output, 0 to +6 dB level adjustment, and emergency audio muting for fire systems.

Its 20 Hz to 20 kHz frequency response, 0.06% THD at 1 kHz, compact 4 × 1.5 × 2.75-inch form, and 36-month warranty provide concrete specifications for system planning. Selection should be based on compatibility with the AtlasIED WTSD wall plate mixer platform and the installation’s audio-output and emergency-muting requirements.
