Overview

The Furman M-8S is a single-rack-unit power conditioner and sequencer built for professional audio environments where controlled power-up and power-down sequences matter. It provides nine total outlets: six sequenced outlets on the rear panel divided into three groups that power on in succession, two unswitched rear outlets for always-on gear, and one unswitched convenience outlet on the front panel. The sequencing prevents the inrush current spike and audible transients that occur when amplifiers, powered monitors, and processing gear all switch on simultaneously — a common concern in live sound, studios, and installed AV systems.

Power sequencing can be triggered from the front panel momentary switch or from an external source via the rear panel terminal block, which accepts both momentary and maintained contact closures. This makes the M-8S compatible with third-party control systems, remote wall switches, or automation setups. All outlets receive standard-level AC surge protection and EMI/RFI filtering to reduce electrical noise that can introduce hum or interference into sensitive audio signals. Rated at 15 amps, the M-8S handles typical rack configurations comfortably, though racks loaded with multiple high-current power amplifiers may require additional circuits. All configuration connections — terminal block, sequencing settings — are accessible from the rear panel, keeping the front clean and uncluttered.

Pros & Cons

👍 Pros

  • Sequenced power-on across three outlet groups prevents audible pops and inrush current damage when powering up a full rack.
  • Nine total outlets (six sequenced, three unswitched) provide flexibility for both switched and always-on equipment.
  • Rear terminal block allows remote or automated triggering of the power sequence from external control systems.
  • Standard 1U rack-mount form factor fits neatly into any 19" equipment rack.
  • Front panel unswitched outlet provides convenient access for temporarily plugging in tools or test equipment.

👎 Cons

  • Standard-level protection only — lacks Furman's higher-tier SMP+ or LiFT technologies found in premium models.
  • No voltage or current metering display, so you cannot monitor power draw at a glance.
  • 15-amp rating can be limiting if your rack contains multiple high-draw amplifiers.
  • No USB charging ports or modern convenience outlets.
  • Sequencing delay timing between groups is not user-adjustable.

Frequently Asked Questions

The M-8S powers on its six rear sequenced outlets in three groups with a brief delay between each group, preventing the current surge that can cause audible pops or stress to equipment when everything turns on simultaneously.
The six sequenced rear outlets power on and off in a controlled order when you use the front panel switch. The two unswitched rear outlets and one unswitched front outlet remain powered at all times, which is useful for devices like wireless receivers or clocks that should never lose power.
Yes. The rear panel terminal block accepts a momentary or maintained contact closure signal, allowing you to trigger the sequence from an external control system, remote switch, or automation controller.
Yes, it includes standard-level AC surge protection and EMI/RFI noise filtering on all outlets to guard connected equipment against power spikes and electrical interference.
The M-8S is rated at 15 amps, which is the standard capacity for a single 120V household or venue circuit in North America.
