to the technical guys, sir...pwede p0 ba i-modify ang isang avr na walang "preamp out" feature para lagyan ng preamp out-socket? maybe the "record" socket of the vcr/v-aux can be modified? i am sure owners of entry level avrs would want to have this "preamp" out feature so they can use an external power amp and improve the audio quality of the avr, hindi lang pang-HT, pang audio pa!

You'd have to do some internal circuit modification. If you have a circuit diagram and can trace the receiver's circuit board, you'll have to scrape off the copper joining the preamp to the power amp, identify the signal ground path and have these RCA output-terminated. An experienced techie or techie-hobbyst can help here.

It will be also nice if you can disable the supply going to the pre-amp. This way you can deliver more power to the power-amp. Also, you may want to use a slightly lower rated fuse for additional protection.

My hunch was right. Burr brown DAC will be used in the next Yamaha entry level receivers RXV459, 559,659. Their technology consistently trickles down every year from higher end models to the entry levels.

I saw a surplus yamaha being sold here, and I was wondering if anyone knows anything about the unit. Its a Yamaha AVX 1000 DSP.

Not really sure if its a good receiver, but I would really want to know if it is.

Is this good for a starter setup?

Puro bata pala. Kaya siguro mabilis ang improvements ng mga models nila.

im currently using Euros 8 system, matched with RXV995 with DTX 4.15, all I can say is awsome with this performance on the price tag, this is a "bang for the buck". though I thought my 4.15 will over power my 2 towers but it came to me that RVX995 has a subwoofer level so adjustment can be made directly with the AVR, so fixed adjustment on the sub with a 50hz cutoff...

I have the 1400 pero di ko pa na-compare with the 657. So far, no regrets on the 1400. I think this amp likes being driven hard/loud. You'll get to really appreciate the power of this amp as you bring it to high volumes. Solid yung sound, and not bright at all. Yamaha amps are known to be suited for HT instead of audio, but the 1400 is quite capable for both. Maraming DSP surround modes, but 95% of the time I just use the Adventure mode on DTS (kung available). The amp is quite heavy (which is good, I think). I'm just a casual listener, so you may want to rely on more expert reviews on these sites:

Matagal na bro. 1500 was last year's model and meron nang 1600. But since yamaha always trickles down their older technology to newer lower models. Its safe to assume that the 1400 has its technology trickled down to the Yamaha 750, except for the amp. They use a different amp for the x50 and the x500 (or x400) series.

And the 1400 is THX certified, and one of the THX licensing criteria is "'The power amplifiers should be unconditionally stable, have a power output in excess of 100W per channel into 8 ohms, have low distortion and wide dynamic range". The quote is from Lucasfilm's Home THX Design And Licensing Manual.

I dont know where I read this, but the lower series' posted power ratings are stereo (2 channel) and they divide it to 5,6 or 7 channels when you use multi channel. Thats why the lower series true power ratings in multichannel reach only about 30+w when I saw it in a review.

I think this is also the reason why I have read or heard some have commented that Yamaha sounds thin or underpowered. This is due to the fact that they were referring to the lower series of Yamaha (w/c is commonly used by more people) and not the higher 1x00 and the 2x00 series. I, for one , am guilty of this, having used a 450 and 650 before.

just my 2 cents

*lower series refers to RXV350/7, 450/7, 550/7, 650/7, 750.

MAtZTER · « **Reply #2418 on:** May 05, 2006 at 11:14 AM »

Come to think of it, the lower series weigh around 25 lbs while the higher series weigh +/- 40 lbs.

But like someone once said, you wont be able to use the whole 30+w, and on all channels for that matter anyway.

baka may faulty connections check mo maige connections mo from source (player) to output (speakers) if problem persist baka may problema yung yamaha amp mo.

turismo1997 · « **Reply #2424 on:** May 14, 2006 at 03:12 PM »

yup. I checked the connections. ok naman. wala naman nag cross na cable, lalo na sa speaker..

Bro,

You may try to remove all the speaker wires at the back of your amp and power it up afterwards. If the trouble is on your speakers, then there should be a message displayed on the screen of the amp. If the amp will shut down again, then there's a problem with your amp. Hope this helps isolate the problem.
