O Audio plate amps

Has anyone used or heard one of these?

I need a couple of plate amps and these look OK and are certainly not expensive. $400 for 2 of 300w amps delivered to the UK.

These look like the BASH amps also available from parts express.

They do look very similar, identical functions and spec from what I can see but slightly different control placement and one has an LFE input.

Are the PE BASH amps any good?

They are better than the PE ones because the PE ones have fixed high-pass filters.

In addition, the O-Audio 500W one also has a parametric equalizer (just one band though).

I have the 500W. I love it. It barely gets warm even when it's cranked.

If I had to do it all over, though, I'd get a rack amp. instead. But I'd stick to Class-H or D.

Thanks DonoMan. 🙂

I'll give the O Audio amps a try.

I looked at the specs for both the 300w and 500w OAudio plate ampson OAudio's web site and think DonoMan is wrong in two ways:
1. Either OAudio amps do not appear to have have a variable high pass filter as implied.
2. The PE 500w equivalent (URL=http://www.partsexpress.com/pe/showdetl.cfm?&Partnumber=300-806]Dayton HPSA500[/URL]) does have similar parametric equilizer (and similarly also doesn't have a high pass filter).

I went with the cheaper PE 240w plate amp because its roughly half the cost and and has provision for speaker and line level inputs. It has a fixed high pass filter set at 160 Hz for 8 ohms but I don't use it. The high pass filters in most(?) plate amps are invariably a simple 1st-order crossover that frequently requires the addition of a passive impedence flattening circuit for the satellite to maintain a flat freq. response.

I would hazard that the higher end 500w plate amps don't include a high pass filter because they count on you connecting your satellites to a HT receiver and solving the high pass crossover problem within the receiver.

Cheaper and all you want for the satellite

Yes this would be a good solution but as noted on this link "Note: this item can not ship to Finland, Germany, Switzerland and Canada". I wonder why...

 

[Sergelisses]

I think the price is more expensive in these countries

Could it be because those places already have a retailer? Creative sound carries these in Canada. Creative Sound

- yes - good catch!

Hi Quickshift,

How did you get on with these?

Check out the thread to bash or not to bash. I posted it and found a slew of info out on both amps.

Hiya,

Actually not too bad. They certainly seem to get the job done. Way powerful enough for what I need and they sound pretty clean. They are surprisingly small and light 🙂 I'm happy with them.

Both amps are in my mark II POC subs - 2 x Peerless XXLS 10" drivers per side in 75l enclosures tuned to 17.8 Hz.

I'll pop up a thread at some point as I'd be interested in feedback on the alignment I'm using.

Thanks gents, much obliged

For any Aussies interested in these, and I am, they will be instock soon in Melbourne

And the price is reasonably reasonable
