4 Zone High Definition Acoustical system

Ideal Use Cases

The AtlasIED Z4-B is a four-zone, all-in-one acoustical system designed around three specific functions: speech privacy, background music, and paging. It is suited to installations that need these capabilities distributed through a four-zone system without treating each function as a separate audio solution. The combination is particularly relevant where intelligible paging, consistent background music, and enhanced speech privacy are all project requirements.

Each of the four listed outputs provides 30 watts at 70.7V/100V. This configuration makes the Z4-B a focused choice for projects based on distributed audio infrastructure. Its available input types also support several common source categories, including a balanced microphone or line-level source, a summed auxiliary source, and Bluetooth.

Why Choose This Model

The central reason to choose the Z4-B is its combination of four-zone operation and multiple audio roles. AtlasIED describes it as a single solution that supplies high-quality speech privacy while also delivering high-quality background music and paging. This clearly defined feature set allows the system to serve installations in which privacy and general audio distribution must coexist.

The input configuration provides practical source flexibility. A balanced mic/line input uses a 3-position Phoenix connection, while a 3.5 mm summed unbalanced auxiliary input accommodates another wired source format. Bluetooth provides a wireless input option. Together, these inputs allow the system to accept microphone, line-level, auxiliary, and Bluetooth sources as specified.

Installation and Integration

The Z4-B provides four 30-watt outputs designed for 70.7V/100V systems. The listed output impedance is 115 ohms. These details should be considered when matching the unit to the intended distributed-audio design and connected equipment.

Power information includes a 24VDC input through a 2-position 3.5 mm Euro Block. The listed operating-voltage range is 110V to 230V at 50/60Hz. Because both details are part of the supplied specifications, installation planning should account for the stated power-input connection and operating-voltage information.

The available product data does not specify dimensions, weight, mounting options, operating temperature, or included accessories. Those fields therefore remain unassigned in this listing. The supplied imagery references related items, but it does not establish that those items are included with the Z4-B.

Performance Highlights

• Four-zone acoustical system for speech privacy, background music, and paging
• Four 30-watt outputs at 70.7V/100V
• Balanced mic/line input through a 3-position Phoenix connector
• 3.5 mm summed unbalanced auxiliary input
• Bluetooth input capability
• Signal-to-noise ratio greater than 90dB below rated output, A-weighted
• 115-ohm output impedance
• Listed idle power consumption of 160mA

These specifications define a system centered on distributed audio performance and flexible source acceptance. The greater-than-90dB A-weighted signal-to-noise specification is stated relative to rated output, providing a concrete reference point for evaluating the system’s audio performance.

What Makes It Different

The Z4-B is not presented merely as a four-channel output device. Its stated purpose combines speech privacy with background music and paging in one four-zone platform. That functional combination is the model’s defining characteristic. It addresses projects where privacy-focused acoustics and everyday audio communication need to be handled by the same specified system.

Its mix of balanced mic/line, summed unbalanced auxiliary, and Bluetooth inputs also distinguishes the source options available to the installer. The wired connections cover microphone, line-level, and 3.5 mm auxiliary formats, while Bluetooth adds wireless source connectivity.

Final Assessment

The AtlasIED Z4-B is a purpose-defined four-zone solution for installations requiring speech privacy, background music, and paging. Its four 30-watt 70.7V/100V outputs, multiple input formats, 115-ohm output impedance, and specified signal-to-noise performance provide the principal technical basis for selection.

For buyers comparing systems on confirmed specifications, the Z4-B offers a clearly documented combination of four-zone output and wired or Bluetooth input options. It is covered by a 36-month warranty from the date of purchase.
