voltage converter suggestion for my small amp and receiver

[boo3dmax]

hi all,

sorry if am repeating the things already discussed, i did the search and learnt something on this forum itself, but wanted to confirm and get your advice as well..

i have yamaha RX-V367 5.1 HT receiver and energy take classic 5.1 speakers subwoofer

the spec says :

AC 120V 60Hz and 250 W/ 320 VA for yamaha receiver
and
120V 60Hz 1.0A for my subwoofer where the sound output is 200V

please suggest me which voltage converter i should go for, i want to buy in chennai this month end. Thanks again.

Hi,

You can go for an isolation type 220/110 step down transformer for the AV receiver. It will cost you around 2400. People have always liked the maxine brand.

For more details you can go through this thread -

http://www.hifivision.com/av-lounge...-110v-step-down-transformer-av-receivers.html

And about the Sub-woofer no idea ...... I am not sure if an auto-transformer will be fine enough or you need to go for an isolation transformer as well.

If possible try to have a single isolation transformer with sufficient KVA rating. But, I hope that won't break ur bank

Maxine is a good brand go for it.

 

[boo3dmax]

regd subwoofer? also is it better to go for a single converter for both? cost wise as well?

 

[binaya.kumar]

Then you should go for one. It saves space and complex wiring .... The usual formula is Capacity of transformer=Watts required by equipments * 1.5

And I read it somewhere in this forum itself.

CHEERS

Boo3dmax,
I too have read lot of good feedback about Maxine.
From where in US you have purchased the energy take classic 5.1 speakers and for how much?
I have recently purchased Onkyo SR508 AVR from US, it is in process of getting shipped to India through borderlinx.I am looking for energy take classic 5.1 in Bangalore but not able to find any stock with RelianceDigital. If I am not able to find it , I might have to get if from US through borderlinx or shopyourworld.

reliance digital has a demo piece last time I checked. If you are ok with display peice you can bargain well and pick it up.

Also few other things you need to keep in mind before buying in US.

Isolation 1.5KV transformer from Vishal is around 3500. Not sure how much Maxine is.

My Pioneer vsx is rated at 250 watts plus each speaker is 110 W..so thats 700 W..apprx 1000 in total. So hopefully if one buys a 1.5KV transformer..he can plug in another gadget with rating of 3-400 watts.

I have a UPS with 800 VA rating. Not sure if this VA is same as watts..but I did get a clarification from one of the members here that my 1.5KV in current avataor of receiver plus speakers only being 1000 watts will overload my UPS....meaning I have to plug my transformer directly into a socket not served by UPS.

Also if you buy 1.5KV and above it may come with 15amps switch which normally one doesnt have near the TV wall....

all things I realized once I landed here with my receiver..if I had known this earlier...may have bought Onkyo 608 in India itself.

Please let me know your views:clapping:

Speakers so not have power requirement of its own, it receives power from amplifier itself. Only exception is in case of powered speakers like subwoofers.

So, total Watts requirement in this case would be 250W (It that is the requirement of amplifier / AVR).

And given that this wattage is not drawn at a constant rate, you would need power rating of transformer to be at least 1.5 times.

With that, you need 500 W (that is approx 650 VA) to run this receiver + speakers.

+1 to the above

thank all, this is what i wanted..so in my case, it should be 320 VA for receiver + 300 VA (200 W) for subwoofer = 620 VA minimum, please suggest.

This is really confusing. One of the boarders who has been thanked a zillion times clarified that even speakers wattage needs to be added. Based on this i ahd made up my mind to return my Vishal non isolation 1 KV and get a 1.5KV isolation instead. is there a website where I can get this clarified. Based on your logid..my 245 watt receiver plus say 255 watt subwoofer makes it 500X1.5=750 watts which my 1KVA should handle comfortably....p:sad:

I am pasting the reply I received from one of the most respected boarders.

"You should always look for the worst case scenario. You amp can pump 125 watts per channel into 7 channels. That mean it could draw a max of 875 watts when pushed. Add 50% for safety and you need a 1.5kVA transformer.
The 245 watts is when the amp is idle. When you are using the amp, it will draw current based upon the output wattage specified. This for your amp is 125 watts per channel multiplied by 7 channels. Now add 50% for safety. "

Which amp is this?

Amp itself would have peak and nominal power rating as part of its specs.

Pioneer VSX 1020

This Amp does not handle 125 W per channel.

Output is 80 W per channel in stereo mode for full frequency. So, a 1 KVA transformer is more than enough.

It does not specify power output in 7.1 mode.

As per specs:

Amplifier section
Continuous average power output of 80
watts* per channel, min., at 8 ohms, from
20 Hz to 20 000 Hz with no more than
0.08 %** total harmonic distortion.

The electrical power the appliance consumes can be worked out from the current it draws multiplied by the voltage. This will give the Volt ampere rating. You can have a 50% mark up on the worked out VA for protection. As per the image uploaded in Amazon the receiver has a wattage of 245 watts therefore a 1 KVA stabiliser would work wonderfully well with this.

How are these compared to the big clunky boxes?

MDR Electronics - MX Electronics - Home Theater Cables & Connectors - Computers & Laptop Accessories - Pro Audio / Studio Audio Cables & Connectors - Audio Video Components & Accessories - Fiber Optic Component & Accessories - Cable TV Component & Ac

Any major drawbacks? I was looking to power a set of powered speakers drawing 65W. Do I need to go for the traditional box version

Hey Guys,
Could you please let me know how much does a isolation step down transformer 1.5 kva cost from Vishal, Bangalore.

Thanks,
Amit

Output is 80 W per channel in stereo mode for full frequency. So, a 1 KVA transformer is more than enough. It does not specify power output in 7.1 mode.

Eve if the specifications are not showing for 7.1 channel, it is safer to assume that the max wattage the amp would deliver is 7*80 or 560 watts. Add 50% for safety, you are looking at a minimum of 840 watts. This is only for the amp.
