Who'll be the coolest new neighbor on the block?

I was using the NTSC TV only for my daughters NTSC VCR and game console. e wouldn't work with a PAL TV.Though it got fried even with a transformer.

Post retracted. (by me, lil' ol SS). All I'll say is I appreciate everything Outlaw tries to do for its customers.

You guys are great.

By the way... $18,000 ? CHUMP change !

Hello all ! Had to use a proxy in order to log in to these forums, so I can't say I feel welcome anymore

The wife and I have managed to settle down a bit, here in Hungary. She's working in a nice five star hotel (her field) and I'll be teaching English until I find something more along the lines of my work.

When last we spoke, I was tempted to try out a European production model which Outlaw had offered to try and get to me. I changed my mind though, because it just didn't seem cost effective in that we don't know how long we will be here for.

I've been looking at some audio gear here, especially some Rotel stuff on the lower end of the spectrum. However, while I was browsing another site of a totally different nature, (lighting equipment for flash photography) they linked to three websites which they recommend for the purchase of step down power transformers, for their gear.

This made me wonder about whether or not I'd be able to get away with using an 800-1000 watt true magnetic power transformer for my RR2150 rather than needlessly spend more and more $ on gear which may or may not be kept.

I realize that this was sort of covered already in this thread, but I just want to make sure nothing was missed. The biggest concern and question was that of 60 vs. 50 Hz coming into play. Gonk already stated that both were single phase units, and the converter handles going from 240 to 110, so all which seems to be left is the 50Hz issue.

I suppose this question goes out more to Scott and Co. at Outlaw, but also to anyone whom might have had experience with their audio gear and transcontinental usage.

Alright kids, be well !

I note that on the product description page for the RR2150, the word 'only' follows the 60Hz indication.

With some experience living in a 240v 50Hz country, my electronics concern was primarily with fact that a coil's inductance generally means that lower frequency current meets less resistance, and in a transformer, a magnetic fields that rise and fall more slowly transfer power with less efficiency.

I don't know what kind of power supply is in the RR2150, but my equipment at the time used standard multi-tap transformers with solid-state rectifiers that fed an ordinary compliment of capacitors. My solution was to run my step-down transformer at 100v, not 120. At idle, the power supply transformers in my gear remained nominally as cool as they did at 120v 60Hz. But for use, I kept the volume low to moderate. With less voltage to start with, and slightly reduced transfer efficiency, I didn't expect the amplifier power supply to be at it's full voltage nor be able to meet heavy demand.

I would expect the RR2150 to survive and perform well if not pushed, as long as there is sufficient 'headroom' in the power supply design. Caveat: my remarks are a best guess based on the equipment I had at the time and my experience with it. I wish you well.

well look's like i'm going to have to wait before i order the as I require 220-240v..

50-60 hertz relates to your v-sync on your power line cycles..


last time i enquired about a step down transformer they were over $200 AUD, now power plug converters probably $50-60 AUD.

each countries prices can be different when it comes to step-down or step-up convertors..

if someone fried a tv then, the possibility of a power surge could of caused damage, 1st time i ever heard of a vcr taking out a tv in any manner..

I could never understand why the yanks have a fixation on running all electronic gear on 115-120v ac..

Have you contacted Outlaw yet to ask what current production units offer on power supplies? It's been nine months since the post reporting that Outlaw had samples on hand that offered 120V/240V power supplies. You might not have to wait very long now.


Frequency of power distribution did traditionally affect the refresh rate for CRT's (which I'm guessing is what you mean by "v-sync"). It would probably be more accurate to say that 50Hz and 60Hz are the frequencies at which alternating current power is distributed from generating plants.


No particular reason. Except for decades of tradition, hundreds of millions of square feet of buildings that are wired for 120V at the point of use, countless industries that manufacture products for 120V (light bulbs, hair dryers, alarm clocks, TV's, computers, cell phone chargers, computers, toaster ovens, and probably one or two other things), and the National Electric Code. It's sort of like my fixation for breathing oxygen - my personal infrastructure is built around the idea of having O2.

Commercial structures in the US do use other voltages (lots of fluorescent lighting is actually 277V/1ph and we frequently use 480V/3ph equipment for large loads like air conditioning and big motors because it reduces wire sizes) and residences routinely use 208V for appliances like ovens, air conditioners, and clothes dryers. And of course we distribute at much higher voltages, with utility transformers providing end users with either 480V/277V or 208V/120V. At the end of the day, for basic "plug loads," 120V is a necessary fact of life.

All my stuff seems to work pretty well at 60 HZ and 120V. Frankly I have never understood why Europe is at 50HZ.

because that is the power cycle for ac, which runs at 240v for the most part, I think in most cases in the US I would say it was a by-gone era of DC power plant generation before AC was a standardised for use throughout the states..

I also the the reason 120v is pushed so much because you can hold more people on it..

as for 3-phase it depends on the connector used, which depends on the current you get..

3-phase wiring is usually a 4 pin setup, using 2 pos, 1 neg and 1 ground.. now gow much current you get will depend on how big the cable is..

getting back subject I was saying what i was saying because the documentation so far is still only stating 115-120v not 115-230v or 120-240v..


being in a country where your on 240v AC I prefer the unit support to 240v where possible, i don't like having to run power converters just so i can run 1 piece of equipment...
