Atlas Sound TSD-DA28 – 2x8 Balanced Audio Distribution Amplifier

Product Overview

The Atlas Sound TSD-DA28 is a 2-input by 8-output balanced audio distribution amplifier designed to route two independent line-level audio sources to up to eight isolated output zones with individual level control. This commercial audio distribution amplifier is well-suited for convention centers, houses of worship, sports bars, restaurants, and industrial facilities where a single audio source must be delivered cleanly to multiple destinations without crosstalk or impedance conflicts. Long-tail applications include multi-zone audio signal distribution for AV systems, isolated balanced line output splitters for commercial installations, and distributed audio level control for eight-zone paging or background music systems.

Product Description

The TSD-DA28 provides two independent balanced line-level inputs and eight isolated balanced outputs, with per-output variable level control. Isolation between outputs prevents crosstalk and removes impedance-mismatch concerns between connected devices. All input and output connections use removable phoenix-style connectors, which are convenient for field wiring and system reconfiguration. The two inputs can be paralleled to create a 1-in/8-out configuration when a single source needs to feed all eight outputs. Each output channel has signal presence and peak indicator LEDs for fast system diagnostics. High-gain output drivers extend the usable cable run length to remote locations. Security covers protect front-panel level controls from unauthorized adjustment after commissioning. The unit operates on a 24VDC power supply that is sold separately; its 80mA power draw allows multiple TSD units to be powered by a single TSD power supply. Physical dimensions are compact: 1.5" H x 4" W x 2.5" D, weighing 6 oz. CE marked; 36-month warranty. A TSD Power Calculator tool is available on the AtlasIED website to help specify the correct power supply for multi-unit installations.

Frequently Asked Questions

Q: Does the TSD-DA28 include a power supply?

A: No. The TSD-DA28 requires a 24VDC power supply that is sold separately. The unit draws 80mA, so it can share a power supply with other TSD series devices. Use the AtlasIED TSD Power Calculator to determine the correct supply for multi-unit installations.

Q: Can I use both inputs to feed all eight outputs simultaneously?

A: Yes. The two inputs can be configured independently (two sources to eight outputs split between them) or paralleled together for a 1-in/8-out configuration where a single source feeds all eight outputs.

Q: Are the output levels independently adjustable?

A: Yes. Each of the eight output channels has its own variable level control, allowing zone-by-zone balancing. Security covers prevent accidental adjustment after commissioning.

Q: How far can the TSD-DA28 drive a balanced audio signal?

A: The high-gain output drivers are designed to maintain signal integrity over long balanced cable runs to remote locations. Specific maximum distances depend on cable gauge and installation conditions.

Q: What connector type is used on the TSD-DA28?

A: All I/O connections use removable phoenix-style connectors for clean professional termination and easy field reconfiguration.

Q: What is the warranty on the TSD-DA28?

A: AtlasIED provides a 36-month warranty from the date of purchase.

Q: Can multiple TSD-DA28 units be used in the same installation?

A: Yes. Multiple TSD series devices can be powered from a single appropriately rated 24VDC power supply. Use the AtlasIED TSD Power Calculator to determine requirements.
