I doubt power filtering matters so much nowadays but it probably doesn't hurt. But power sequencing can avoid unpleasant thumps and having it on one easy switch is nice, no forgetting to sequence well. I ordered the more expensive brand of the same exact build and it made a slight humming noise, this Monoprice didn't have the humming noise and I kept it. Nice warehouse deal.

This worked out great in my rack. Thanks. Great sequencer at a good price.

It's a bit bigger than the standard rack mount units; it has one great sturdy power-on button, this unit has logically placed Led lights on the front panel that illuminates green. The power cord is of good quality. The unit does separate the three zones adequately. The only drawback is there are only two outlets connected to zone 3; this is the zone that powers on last. Since I have three amplifiers one of them has to be plugged into zone two for lack of outlets. so I am still getting a pop sound generated by my Behringer equalizer from one of my amps; when it is turned on. Sure I can install a heavy-duty three-prung plug in the adapter. However, for the money, you spend nowadays. it is just not a good feeling.

I wish it included a relay port for external devices like some Furmans do; And I wish the front outlets were switched or even had their own switch;Butfor dead simple and reliable sequencing of equipment, at an excellent price, you really can’t beat this. I don’t know how long this has been on the market, but I wish I knew about it years ago; I could have replaced several far more expensive power sequencing or less capable distributors with One of these.I am using it to control a small church audio system, in which I need to sequence a thousand watt amplifier, behind a mixing console and various pieces of auxiliary equipment.I may end up buying one of these eventually for my home recording rack as well, and possibly for our church video rack.

It is awesome for the price. The next power bar with sequencing is Furman, and like three times more expensive. There are three zones and they power on in sequence, power off in reverse. It works, it is sturdy, simple and inexpensive. I would like some always on outlets on the back but hey, it is still an excellent product for more than reasonable price.

works well. provides sequential on/off banks, surge protection and basic noise filters.

This is basically a stripped down, Chinese knockoff of the Furman M-8S, but with fewer control features/options. It works as advertised, at an amazing breakthrough price, but you better think it through and know exactly where/how you plan to use it before you order one and start doing handsprings over the money you saved.For example, I purchased this for use in a fixed installation church PA, for the sole purpose of eliminating amplifier "pop" that was occurring at shutdown after our replacement of a VERY old, failed amplifier. However, the guts of this particular PA are run from a single, four-plug AC outlet turned on and off by a simple toggle switch located outside the locked PA cabinet where all the guts are stored, and giving all users access to the PA cabinet is not an option. Result: when the outlet is turned on, the sequencer works normally. When you turn the outlet off, BOOM ... everything powered by the outlet (including the sequencer) goes off simultaneously. So, in my case, out of the box, no help whatsoever on the sole intended purpose of the device.Because I'm such an electronics genius (that's a joke), I quickly divined that the sequencer can't be properly run from a switched AC outlet ... it must have continuous AC power through both startup AND shutdown. The same is true of the Furman sequencer. However, the Furman device has a port on its rear panel that allows the sequencer to be turned on/off via a remote, low voltage switch (e.g., so all users, no matter how tech-challenged, can safely turn the entire PA system on and off, in the correct sequence, by use of one, simple toggle switch located away from the front panels of the sequencer and all the other components that are plugged into it). This sequencer has no such port, so I had to "McGyver" a remote switch of my own and patch it into the sequencer's on/off switch inside the unit (probably thereby voiding the manufacturer's warranty); remove the switch that previously controlled the PA at my church to make power to the switched AC outlet continuous, and mount my custom remote switch in the same junction box that previously housed the AC outlet switch.Fortunately, I didn't blow anything up removing the old AC outlet switch, and my custom remote switch for the sequencer works perfectly. Startup/shutdown of the whole system is now controlled exclusively by the sequencer from a simple toggle, but it took a lot of head-scratching to get there. This sequencer does exactly what it says ... not the manufacturer's fault that I couldn't figure out before I bought it whether that would work for me.My only complaints (one star off): the fit/finish of the outer case hardware is a little rough, and I got ZERO help from Monoprice tech support on the issue I was having at first. But come to think of it, what could they tell me? "Sorry ... no port for remote switch on our product ... you're screwed?" It's OK, guys ... I got it to work for me, without any damage or alteration to any of the original components. Notwithstanding the trouble/confusion I had at first, I STILL think this sequencer is a great value for the price.
