I ordered the 220V version, which is advertised to work from 200 to 240 volts. My outlet reads 246V. The amp shipped with some European power plug (http://www.o-digital.com/pic.asp?url..._Cords_418.jpg). I changed it with a NEMA 6-20. The amp worked without issue in the 30 minutes or so that I just tested it with. I was very careful with the gain control. I didn't want to send my poor SDX-15s (x2) to the graveyard In the future I will be getting some Mach5 Pi-18s to use this amp with.

I had no issues with the transaction related to Sanway. Initial impressions says that I will order from them again without reservation.

Can someone walk me through the money transfer details? Do you have to go to a local Western Union, or can it be done online somehow? Do they provide an account # the money goes into, or do they go to their local Western Union branch to collect? What are the costs?

Thanks.

Given a choice, I would use Western Union. My own transaction was with a money transfer thru a bank, but the bank money transfer system seems like a very old system. It had a limit on the number of characters for the beneficiary name, and the Sanway beneficiary name provided was too long for the form. The bank teller shortened the name, and the money transfer was rejected by the Bank of China. This caused a 6 day delay for me, and I had to pay the money transfer fee twice.

I looked at the Western Union website, it seems you can do the money transfer over the web. Contact Sanway for the exact information that you need for the Western Union site. They will know what you need.

Thanks. I will contact Sanway to find out how they want it transfered. It is just an uneasy feeling doing a wire transfer to China....I am glad to hear it works and they are not a fly by night operation. Let us know how that FP14k is doing after you put some miles on it.

Ok, so this is my third post so I can send a link to what seems to be good unbalanced to balanced adapters in my next post...

Check out these two items to match unbalanced outputs to the balanced inputs on a professional amp:

I have the matchbox in my system. It substantially boosts the signal.

DL86, Does the Matchbox work well besides the gain? Are there any frequency response or noise issues (to include hum) with it, or does it work as advertised?

I also have a Matchbox HD. It's frequency response is flat and it makes no noise whatsoever. I'll be selling mine after the Subwoofer GTG in Omaha.

It is spec'd as flat from DC to 20kHz. I haven't measured it. I was looking for it this morning and was going to bring it to work, but I picked the wrong audio box to look through. My current signal chain is down .8 dB at 10 Hz and 2.7 dB at 5 Hz. I'll insert the Matchbox HD in the signal chain and do a loopback test with REW to see if anything changes.

Oh cool!

Are you installing those fans or did you get Sanway to install them for you? Either way, I'd like to know how loud the amp ends up being.

Works as advertised. No more noise in the system with the box than without the box that I can detect. Haven't tested its FR hasn't seem to made any change to the sound though.

The schematic is included in the manual. Good text book design. I like it.
Cost $200 though.

So is this the best amp to drive my IB system? 4 18's per channel.

Marantz 7702 Atmos
3 Inuke NU4-6000 amps for all speakers.
Speakers- 7 Behringer B215XL's, 4 212xl's for ceiling speakers.
subs- SI 18ht x12 IB powered by Inuke 6000.

Well it was reported to surpass the marathon 5050 which was highly touted as a solid sub amp. From all reports thus far you can do cheaper (since IBs don't require a lot of juice) but not better.

Don't I need 550 watts per driver?

Need? Doubtful in your scenario but your final impedance will decide the amp output. If 4 ohms then on paper you'd be about double in re to the 550.

Email sanway.audio@gmail.com. State model you wish to purchase, your shipping address and phone number and Johnson will send you back a quote and details on how to pay for it. Also request quiet fans if you want.

youll get a little more than that running the 14k at 8 ohms as we discussed in your thread, i dont know if scott or Bigbaddaboom ran a graph for you or not but you need to make sure that your excursion is held under control with 586 watts per driver.

Yellow line here is assuming 4700w (587.5 per driver). With 2ohm IB318's, wired in series for a 8 ohm stereo load:

Awesome thanks. I try to make this simple. So I want an 8 ohm load on both channels which is easy for amps so the question is if I buy 8 2 ohm IB3's I am assuming I would wire 4 drivers together for each channel. How do these get wired?

Yeah, but we're in the danger zone then:



He'll have 115dB at 10Hz before taking into account his incredible room gain at 8ohm.
