    Furman M-8S reviews

    Merit M-8S Power Sequencer is rated 4.4 out of 5 by 5.
    Rated 5 out of 5 by from Spending but works flawlessly as acticipated I needed to simplify the power on/off sequence for volunteers in our church youth room. I shopped around for a cheaper unit with similar functionality and came up empty-handed. I use several other Furman units and all of them work flawlessly so I anticipated the same with this unit. It was super easy to install. Within minutes I had it working just as I hoped it would. It is actually more feature-rich than I expected. I purchased two more for another sound system upgrade project. It seems pricey for what it is and does, but it seem worth it compared to the wear and tear on equipment.

    Rated 5 out of 5 by from Solid and dependable We use these in our audio racks to power up/down components in the courtrooms. We have tried other brands but they were not reliable. When I put these in , I can forget about them for a long time.

    Rated 4 out of 5 by from Simple to set up Unit does what I wanted it to do. Volunteers weren't reading directions on proper power up procedure for audio equipment. Unit delay allows audio processors to boot up before amps to protect speaker from pops. Have another more expensive unit that allows you to adjust how long the delay is but this unit worked for my application.

    Rated 3 out of 5 by from M-8S Admittedly an amateur, I am a little disappointed in the noise filtering performance of the M-8S. While I have noticed cleaner sound performance, I still have a bit of a hum in our system.
