receptor shutting down in mid-performance

[kebbydog]

we have a band on the road and the keyboardist has been experiencing intermittent shut downs of his receptor. last night it happened several times during a single set. any one have any ideas what's happening? could this be a power supply prob within the cpu?

any help is much appreciated. important tour starting in 9 days.

thank you

Possibly heat is the issue, or more likely, low power at the AC outlet (with all the stage lighting and amps, it's easy to be overdrawn.) Suggest a power conditioner with constant power out - Tripplite or some such.

thanks, this might be a possibility. fyi, the muse sits in a rack with other hardware, all power coming through a furman power strip, not a conditioner - only the muse is shutting down. maybe it's more sensitive that the other hardware?

thanks for your interest and support

Yes, if it only happens onstage, it seems most probable that it is a venue power quality issue. If the shutdowns also occur at home or in the studio, well, the cause might be a little less obvious.

On the power issue, just to split hairs with thesoundsmith's comment, the issue is really with low VOLTAGE. So you would want to find a power supply/conditioner that outputs a constant voltage (compensating for fluctuations in venue line voltage). Furman is another supplier of such units.

Hopefully someone from Muse will chime in with info on the Receptor's susceptibility to low input voltage. Until then, if you have the opportunity (another gig?), maybe you could get yourself a voltmeter to measure the output voltage from your power strip and sorta keep an eye on it during your performance. You could at least see if the voltage fluctuates, and by how much, or if it's well below 117V in general (assuming you're in the US). It'd be nice if you could find a voltmeter with a plug on it that you could plug into your power strip. If you use a conventional meter with probes, it's definitely do-able, just be careful!

One other thing: do your shutdowns only occur at seemingly random times, or do they happen in response to some action such as a MIDI program change input?

this is a random event, unrelated to midi program changes. seems like it's either an external power fluctuation issue, as you suggest, or an internal issue, maybe the cpu power supply is bunk.

really appreciate your interest and input

Hi My name is Rich and I know exactly what your problem is. Its Voltage!!! what happens is the power supply in the Receptor gets a low voltage spike, from not enough 20 AMP services where you gigging and the puppy shuts down! Why cause the club your playing at has shit electrical service and has poor voltage from all the draw between the bands gear and lights so your screwed in plain English. What you need to do buy is a voltage Regulator from either Furman or Monster.What happens is it stabilizes voltage coming in so if a spikes hits your gear it will stay up and running because the VR has stabilized everything plugged it the unit. Worth every penny if you tour and even if your a local act trying to get a deal!!!!

Hi, I have exactly the same issue. My local Muse dealer informed me this is power supply problem. This week I am sending Receptor back and they are going to replace power supply. I hope it will help.

Hi,
The furmans have proved to be a bad combination with Receptor. Multiple artists both I and Muse have worked with have experienced problems related to this.

Is it almost certain that your shutdown problems are PSU related and you should look into a PSU swap asap. Ask Muse who your most local service engineer will be and they'll have it sorted in no time at all.

Short update: Receptor's mainboard has been changed to new one. That was not power supply problem as they suggested. Now all is working fine
