Atlas Sound PA40G – 40W Single Channel Power Amplifier Global Power Supply

Product Overview

The Atlas Sound PA40G is a compact, single-channel 40-watt power amplifier with a universal global power supply, designed for commercial distributed audio applications including paging systems, background music, and small to medium sound masking installations. As a 70V/100V commercial power amplifier, the PA40G is well-suited for restaurants, retail spaces, offices, and any facility where a space-efficient half-rack amplifier with worldwide voltage compatibility is required. Long-tail use cases include single-zone 70-volt amplifiers for conference rooms, compact paging amplifiers for small commercial spaces, and background music amplifiers for hospitality environments.

Product Description

The PA40G delivers 40 watts into a 70.7V/100V speaker line and occupies a 1RU, half-rack form factor, making it practical for tight equipment rooms and wall enclosures. It accepts both balanced line-level input via a phoenix-style connector and an unbalanced summing RCA input, giving integrators flexibility in source routing. The global power supply accepts 100VAC to 240VAC at 50/60Hz, eliminating the need for separate transformers or voltage converters in international installations. A security cover locks the level control in place once the desired volume is set, preventing accidental or unauthorized adjustment. Status LEDs provide at-a-glance operational feedback. The PA40G is part of AtlasIED's PA series, built for professional installation personnel with features that meet or exceed typical commercial deployment requirements. It is CE marked and TUV certified, and carries a 36-month warranty. A rack mount kit (PA702-RMK, sold separately) is available for installing the half-rack unit in a full-width rack bay.

Technical Specifications

Frequently Asked Questions

Q: What speaker line impedance does the PA40G drive?

A: The PA40G is designed for 70.7V and 100V constant-voltage distributed speaker systems. It is not intended as a low-impedance (4Ω/8Ω) direct-drive amplifier.

Q: Can the PA40G be used outside of North America?

A: Yes. The integrated global power supply accepts 100VAC to 240VAC at 50 or 60Hz, making it compatible with mains power in any country without an external transformer.

Q: Does the PA40G fit in a standard equipment rack?

A: The PA40G is a 1RU, half-rack width unit. It can be mounted in a standard full-width 19" rack using the optional PA702-RMK rack mount kit, which is sold separately.

Q: How is the level control secured after installation?

A: A removable security cover snaps over the front panel level knob to prevent accidental or unauthorized changes after the system is commissioned.

Q: What is the difference between the PA40G and the PA60G?

A: The PA40G delivers 40 watts of output power; the PA60G delivers 60 watts. Both share the same global power supply design and half-rack form factor.

Q: What warranty does the PA40G carry?

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

Q: Can both inputs be used simultaneously?

A: The balanced phoenix input and the unbalanced RCA input are summed together at the input stage. Both can be connected simultaneously; the RCA input sums into the main signal path.
