Topic: 50Hz AVR's like HK and Denon, any comments?

[Reymer]

Hi. i would like to know from the experts here if there is any problem in using equipment rated for 230v, 50Hz since the AC supply here in the Phils. is at 60Hz. Nung nandoon kasi ako sa Dubai and I was looking for a Receiver, a sales staff (pinoy din) told me that I cannot use it here coz its designed for 50Hz. Pagdating ko dito, I checked and the HK and the Denon AVRs that I saw are also 50Hz. Only the Yamaha and Onkyo were 60Hz. Even my NAD c542 is also 50Hz when I checked.

Reymer,

I've been using a lot of gears from Hong Kong (50Hz) and brought it back to Philippines....and still functioning as of this posting flawlessly.... TV's, Amps, Mini Hifi's, even Microwaves Oven's, and a lot of electronic gadgets.....since I started working here....

No problem so far.....Heck even some of my colleagues in here shipped a Split Type Aircon, Hot & Cold capable Refrigerators, Power Tools, etc...and they said it is still working properly at this time...

Dont worry about that too much....You need to worry if the gears that you're going to bring back home is only 110V.......now you have to remind everybody in your household that it needs a power converter......

Hi,

Any gear with an induction motor may/can have rotation speed problems. I did noticed that 50Hz transformers plugged to 60Hz outlets run a bit warmer as opposed to running them in 50Hz.

Other than that, I think there shouldn't be anything to worry about.

Happy listening.

Hi,

sa pagkakaalam ko ang Hertz ay mas kilala nuong araw bilang "Cycles per second" ito yung gaano kabilis mag palit ng polarity ang AC source. Parang ganito DAW yan:

Ang isang taong payat ay kayang umakyat ng bundok sa rate na 60Km/hr ng sampung ulit, kaya rin ng isang taong mataba na umakyat ng bundok sa rate na 60km/hr nang ilang ulit? (sabihin na nating kaya rin nya 10 times), pero kaya, yun nga lang hirap. Tsaka gaano tatagal ang isang taong mataba sa pag akyat ng bundok. Pero kung 50Km/hr lng ang bilis ng isang tong mataba sa pagakyat ng bundok kayang-kaya.

parang ganun din sa mga electrical device. ang 60hz kayang tumakbo sa 50hz. ang 50hz tatakbo rin yan sa 60hz pero hirap, isa pa mababawasan ang usefull life ng device mo.

yun lang ang pagkakaintindi ko. paki tma na lang ako kung mali ako.

Thanks  Iyon din ang alam ko. Specially those with ac motors (ie, belt drive turntables) since these are frequency dependent. The receivers, I think, pwede since the power is converted to dc before it reaches the main circuits.

I've been using our Denon AVR from HK (50hz), Pioneer DVD player from HK(50Hz), Yamaha Subwoofer from HK (50Hz) since 1996-97 and still, its is functioning as of this time..... aside from JVC TV, Sony, and Toshiba TV's na as of this time eh still functioning flawlessly.......yun nga lang mukang luma na but it is one of its kind nung bago....around 2 yrs pa bago nagsulputan sa pinas yung mga ganong model...but ngayon muka na syang pre-historic....at di ako makabili ng bago dahil sayang naman at di pa sya nasisira....

lets just say na lang na ang lifespan nung Denon ay 20 yrs if using in a 50Hz condition and lets say na mabawasan ng 5 yrs if using it in a 60Hz condition......ABA!!! antagal ko pa pala mapapalitan nung Denon ko, 6+ yrs pa   eh hindi pa nga DTS capable yun eh.....low tech pa......pati na rin yun PioneerDVD player....anlaki pa non.....di pa uso ang DTS nung mabili ko......

For me, regarding those AVR, Amp, CD player, DVD player, digital camera, video camera, TVs, walang problema yan...enjoy your gears....malamang eh obsolete na yung features nyan at gusto mo  nang palitan eh di pa masira-sira yan....hererherehrehrherer

get my drift??

you have nothing to worry about...

Thanks guys. Now I know pwede na pala, basta 220v. No need to worry when buying my gears
