Furman M-8S – 15A Rack Mount Power Sequencer

Product Overview

The Furman M-8S is a 15A rack mount power sequencer built to bring AV racks online safely by powering equipment in delayed stages. Designed for commercial AV racks, studios, and live sound rigs, this sequenced power-up conditioner prevents the excessive inrush currents that stress amplifiers, processors, and other sensitive electronics. As a commercial-grade rack power conditioner with sequencing, it combines surge protection and noise filtration in a single 1RU chassis. It is a dependable foundation for any installation requiring controlled, staged power distribution.

Product Description

The M-8S installs in the top slot of a standard 19-inch rack and energizes its rear outlets in three delayed groups, ensuring connected equipment powers up in stages rather than all at once. This staged sequence reduces the risk of power surges that can damage speakers and amplifiers during turn-on. The unit provides six sequenced rear outlets arranged as three duplexes, each controlled by a separate relay, plus two unswitched rear outlets and one unswitched front convenience outlet for a total of nine outlets.

Beyond sequencing, the M-8S filters incoming AC to remove radio frequency and electromagnetic interference that can introduce low-level noise into an audio system. Its Series Multi-Stage Protection and Linear Filtering Technology keep harmful spikes out while the dual pull-out front panel lights let operators read the rack discreetly in dark venues. For installations that need integrated sequencing in a power conditioner, compare the Furman power conditioner with SmartSequencing, or browse the full Furman power management collection for the right fit.

Key Features

• Three-Stage Power Sequencing — Six sequenced rear outlets power up in three delayed groups to prevent the inrush currents that can damage connected gear.

Frequently Asked Questions

What is the difference between a power sequencer and a standard power conditioner?

A power sequencer like the M-8S energizes outlets in timed stages to prevent inrush current, while a standard conditioner switches all outlets at once. The M-8S adds three-stage sequencing on top of surge protection and noise filtration.

How many devices can the M-8S power?

It offers nine outlets total: six sequenced rear outlets in three duplexes, two unswitched rear outlets, and one unswitched front convenience outlet, all within a 15-amp total load capacity.

How does the M-8S install in an equipment rack?

It mounts in a single ANSI 1RU space (1.75 by 19 inches) and is designed for the top slot of a standard 19-inch rack, with all configuration handled on the rear panel.

Can the M-8S be triggered remotely for AV system integration?

Yes. Rear panel DIP switches and a 4-pin Phoenix remote terminal support 12V, ground, momentary, and maintained triggering, accepting +5-30VDC in and providing 12VDC out for control integration.

Does the M-8S filter electrical noise?

Yes. A Pi LCR filter provides greater than 26dB of noise attenuation from 100 KHz to 1 MHz, reducing radio frequency and electromagnetic interference in the audio chain.

What warranty and support are included?

The M-8S carries a 3-year limited warranty. For warranty claims, product support, or installation guidance, contact Creation Networks at creationnetworks.net.
