So at the theme park I work at the food court also has a stage for small band shows and other special
events, but the PA also plays bgm during the day. The problem is that sometimes there is no one to fire up the rig in the morning or turn it off when the food closes. So what is out there that can power up the
PA system on some sort of schedule or remotely over the web or anything like that?

[Mike Caldwell]

There are power sequencing systems that can be set to do that very thing.
Furman has systems that will do that. It may take some remote modules to power
equipment if various parts are in different locations or to spread the power load
across multiple circuits.

I have done that what your looking to do with the Furman equipment with a standard programmable power timer that closes a relay starting the power sequence.

[Eddie Ybarra]

Do you happen to have a link to the programmable timer?

[Mike Caldwell]

The system is more than just a timer.....unless it is a REALLY simple system.

What components make up the sound system, amps, mixer, processors, ect?

[Eddie Ybarra]

The rack has a couple of driverack 260s a bunch of qsc ex1600 and some probably even older klark teknik dn716. Currently the mixer lives on stage and we use the the analog patchbay to get in and out of the system. Roughly every amp is on its own circuit.

[Mike Caldwell]

Is there any power sequencing equipment in place already?

If not you going to need at least a master sequencer line a CN1800 at the mixer for the mixer
and another other input great.
At the rack maybe another CN1800 for the processing and remote modules for the power amp circuits.

There's a ton of gear out there that can do this sort of thing today.

In the network world, there are multi circuit devices that monitor load as well as can turn on and off individual outlets.

There's also a schmuck ton of stuff in the consumer world that can be used for this, although then you're at the mercy of consumer grade operations.

Alternatively, you could put relays or contactors on the circuits you want to control, then run low voltage lines to a central control and then use any number of remote relay control systems.

There isn’t any power sequencing currently, do you have any experience with the blue bolt control that Furman uses and how has the reliability been?

Limited Bluebolt experience, it worked for the monitoring purpose.
I would keep it simple....as can be with a timer and a PSREL plugged into it to give the contact closure starting the power up process and when the timer turns off the contacts open starting the power down process.

Check your BGM source.  Sometimes commercial satellite receivers will have automation and/or scheduling in them.  The one I use I can program on and off times, output leveles and even station changes at specific times.  The rest of the system stays on all of the time.  A good DSP be can schedule events to turn down an input at closing time.

[Brian Jojade]

A good DSP be can schedule events to turn down an input at closing time.

Heck, even crappy ones can do that sort of thing.

Yeah, leaving stuff on 24X7 is an option too.  Most equipment these days has relatively low idle current draw so leaving it on 24X7 isn't out of the question.  The cost for equipment relays and installation will likely far exceed any electrical savings even over many years.

I designed a sound system for a water park.  The front end is a Yamaha DMNE64, it has an internal clock and mutes / un-mutes itself every day.   We even built in a safety, so if there is an emergency after hours, the paging mic and alarm announcement still work.  There is GPI on the back that can be linked to the events, so you could use that to control relays, etc.  THE DME handles all audio, distribution, multiple sources, etc.  It is the front end for the system.

[Mike Caldwell]

I guess the question is do you want to power the system off over night or just mute it.

Powering the system off will help cut the operational hours in the equipment and may help if there is an electrical supply event over night.

Also, does it really need anything more than a simple timer? digital mains timers are cheap enough and generally have battery back up so if mains is lost for a short period the time is kept correct.

A $20 hardware store digital plug in timer could not power the entire system, it could be used to start the power down and power up sequence when connected to power sequencing equipment.

My approach to a similar problem recently was to use a remote-controlled Power Sequencer (in my case, Furman CN2400), driven by a GPIO relay closure on the system matrix processor (in my case, AHM-32).  While my situation was preset-controlled instead of timer controller, you could program the DSP to switch the relay on a schedule. 

...Thats if your installation has a DSP with GPIO capabilities.  As others have said, network controlled power systems might be better in your case.

The park dsp is peavey media matrix cab8o and I don’t see any gpio currently nothings is being sent to it also there’s talks of the whole park moving to qsys but who knows when that will happen. I like the idea of the AHM, Yamaha etc matrix mixer controlling everything off of a schedule but I’d also like to be able to fire the rig up remotely for a last minute event or presentation cause that happens more times then I’d like to admit.

I programmed the Yamaha DME to have a hot button on front panel to mute /  un-mute manually.
