Product Overview
The Atlas Sound ECS-204 is a rackmountable 20A power conditioner and sequencer that combines staged equipment power-up, surge suppression, and EMI/RFI noise filtering in a single 1RU chassis. Sequenced AC power distribution protects amplifiers and processors in commercial AV equipment racks from inrush current, while Dual Clamping Suppression circuitry guards against lightning-induced spikes and utility transients. With nine total outlets, a front-panel digital voltmeter, and an Emergency Power Down port that supports fire-code compliance, the ECS-204 is a practical foundation for rack power management in houses of worship, government facilities, and performance venues.
Product Description

The ECS-204 provides four internal sequential timing sections: three switch banks on the unit and a fourth output that triggers an external device. Six rear-panel outlets are sequenced in three stages, joined by one unswitched rear outlet and two unswitched front-panel outlets for service tools and laptops, for nine total 20A outlets. Sequencing can be activated locally with the front-panel momentary switch or remotely through a momentary switch, latching switch, or 5–24VDC trigger, which makes AV control system integration straightforward. Sequence timing is selected on the rear panel with four settings from 3 seconds to 2 minutes. When a single 20A circuit cannot cover the amperage demand of a larger equipment rack installation, the sequenced 12VDC or contact-closure output (Seq 4) can trigger devices such as the AtlasIED ECM-20SH 20A standalone AC power module, and up to three ECS-204 units can be linked for 12 sequenced outputs.

Protection is layered. Dual Clamping Suppression (DCS) technology suppresses spikes at the incoming AC mains and again at each sequenced output section, reacting within a nanosecond and sustaining suppression up to 2 milliseconds against transients that can reach 6kV or 3,000A peaks. RFI and EMI filters reduce noise injected by radio transmitters, electric motors, and switching power supplies, which translates to cleaner video and fewer audible pops in commercial audio video installations. An Emergency Power Down (EPD) port shuts off all channels at once where required by local fire code, Extreme Voltage Shutdown (EVS) protects connected gear from abnormal mains conditions, and a 20A circuit breaker with a Breaker Open indicator covers overcurrent events. Dual front-panel USB charge ports power phones or a USB gooseneck lamp, and a rear XLR receptacle accepts the optional AP-GNL gooseneck lamp for rack illumination.

Key Features
- Nine Total 20A Outlets — Six rear outlets sequenced in three stages plus one unswitched rear and two unswitched front outlets cover an entire AV rack.
- Three-Stage Sequencing Plus External Trigger — Four timing sections stage power-up to protect amplifiers and DSPs from inrush current.
- Dual Clamping Spike and Surge Suppression — DCS circuitry clamps transients at the mains input and redundantly at each output section within a nanosecond.
- EMI and RFI Noise Filtering — Reduces interference from transmitters, motors, and switching supplies for cleaner audio and video performance.
- Emergency Power Down (EPD) Port — Shuts down all channels simultaneously to satisfy local fire code requirements during site inspection.
- Extreme Voltage Shutdown (EVS) — Protects connected equipment from abnormal AC mains voltage, with AC fault and wiring fault indicators.
- Flexible Remote Activation — Triggers from a remote momentary switch, latching switch, or 5–24VDC input for control system integration.
- Expandable Power Architecture — Seq 4 trigger output drives an ECM-20SH module, and up to three linked ECS-204 units yield 12 sequenced outputs.
- Front-Panel Digital Voltmeter — Precision AC mains voltage monitoring at a glance, with a security cover over the mains power switch.
- Dual USB Charge Ports — Charge devices or power a USB gooseneck lamp; a rear XLR socket supports the optional AP-GNL rack lamp.

Frequently Asked Questions
How many outlets does the ECS-204 sequence?
It provides nine total 20A outlets: six rear-panel outlets sequenced in three stages, one unswitched rear outlet, and two unswitched front-panel outlets.
Can the ECS-204 integrate with an AV control system?
Yes. Remote activation is supported via a momentary switch, latching switch, or 5–24VDC trigger, and the Seq 4 output provides sequenced 12VDC or contact closure for triggering downstream devices.
What if my rack needs more than 20 amps?
The Seq 4 trigger output can fire devices such as the AtlasIED ECM-20SH 20A standalone power module, and up to three ECS-204 units can be linked for 12 sequenced outputs across multiple circuits.
Does it meet fire code requirements for emergency shutdown?
The Emergency Power Down (EPD) port turns off all channels at once when activated, a capability that may be required by local fire code to pass site inspection. Confirm specific requirements with your AHJ.
How does the surge protection work?
Dual Clamping Suppression circuitry clamps spikes at the incoming AC mains and again at each sequenced output section, responding within a nanosecond and sustaining suppression up to 2 milliseconds, with a 2000-joule energy rating.
What sequence timing options are available during installation?
A rear-panel switch offers four timing selections ranging from 3 seconds to 2 minutes between stages.
What warranty and support come with this unit?
AtlasIED warrants the ECS-204 for 12 months from date of purchase, and Creation Networks provides system design assistance for commercial rack power deployments.
