4×4 Analog/Dante I/O Module

Ideal Use Cases

The AtlasIED IED1544AIO-D is designed for applications that need to convert as many as four analog microphone- or line-level audio signals into Dante digital audio. Its 4 x 4 analog/Dante I/O format makes it suitable when analog audio sources must be incorporated into a Dante-based system. The module is particularly relevant when the required channel count does not exceed four and a compact component is preferred. With a listed input impedance of 2.2kΩ for analog signals and an analog output impedance of 600Ω, the available electrical specifications can be reviewed against the connected equipment before deployment.

Why Choose This Model

This model combines analog audio interfacing and Dante digital-audio conversion in a single module. That defined purpose helps narrow product selection for systems requiring up to four mic or line signals to enter a Dante audio environment. Its documented performance includes a 20Hz to 20kHz frequency response within +/-2dB, a signal-to-noise ratio of 110dB at 1kHz, and total harmonic distortion of 0.06% at 1kHz. These published figures provide concrete criteria for evaluating the module alongside the requirements of the wider audio system.

Installation and Integration

The IED1544AIO-D measures 1.75 inches high, 3.27 inches wide, and 6.55 inches deep, equivalent to approximately 44 x 83 x 166mm. It weighs 1.2 lb, or 550g. These dimensions and weight should be considered when allocating installation space and planning support for the module. Power consumption is specified at 5W, allowing its power requirement to be included in the system power budget. The provided product information also lists a 20Hz refresh rate. Connection types, voltage requirements, mounting hardware, and included accessories are not specified in the available data and should therefore be confirmed separately when planning the complete installation.

Performance Highlights

The specified frequency response covers 20Hz through 20kHz with a tolerance of +/-2dB. Total harmonic distortion is rated at 0.06% when measured at 1kHz, while the signal-to-noise ratio is rated at 110dB at the same frequency. Together, these figures describe the module’s stated audio performance using clear, comparable measurements. The analog input impedance is 2.2kΩ, and the analog output impedance is 600Ω. For system designers and installers, these impedance values provide important reference points when matching the module with microphone, line-level, and downstream analog equipment.

What Makes It Different

The defining feature of the IED1544AIO-D is its focused combination of four-channel analog capability and Dante digital audio. Rather than presenting an unspecified general-purpose interface, the module is identified for applications requiring conversion of up to four analog mic or line signals into Dante audio. Its performance, physical size, weight, and power consumption are all stated, making it possible to assess channel capacity, audio specifications, space requirements, and power needs from the supplied information. The model identification and SKU are both IED1544AIO-D, helping maintain consistency when specifying or ordering the unit.

Final Assessment

The AtlasIED IED1544AIO-D is a purpose-defined 4 x 4 analog/Dante I/O module for integrating up to four analog microphone or line signals with Dante digital audio. Its core specifications include a 20Hz to 20kHz frequency response, 110dB signal-to-noise ratio at 1kHz, 0.06% THD at 1kHz, and 5W power consumption. The compact 1.75 x 3.27 x 6.55-inch chassis weighs 1.2 lb. A 36-month warranty from the date of purchase completes the documented product information.
