Mulit-channel Amp,Which one you would like to own?

[ziggurcat]

Switchable with a remote: we don't want to leave the MLP, do we :-D

It's a power amplifier, not an AVR, so it doesn't need a remote IMO. It just needs an on/off switch with an auto on option, and 12v trigger input -- which is what is shown in the proposed images. Do all of that other stuff with your preamp/AVP/AVR.

I agree with you, however:

My AVR is not the best DAC, not the best streamer so I like to use an external one. That could also be the device to switch the surround vs stereo source.
External DAC's as you find them here in the top of the lists do not have an analog line in, or hardly. The Wiim Ultra seemed to be an exception to that, hurray! But....the analog line in has a delay of (at least, depending on EQ, Roomfit etc)) 50 ms, which my AVR (Denon X4500) is not capable of compensating for. SO I can't use that as a switching point either.

So, next up in the stream is the power amp. I am currently trying out the B100's and they have tow separate inputs, but need to flip switches on the amps.

Maybe my case is absolutely unique and maybe not interesting for a business case, to put product development into...but I'm guessing I am not the only one in this situation. Like to hear E3Audio about this usecase anda maybe they hovae more data on it too.

Just an idea, because I'd rather automate everything instead of flipping switches or pushing buttons: 12V switching could be connected to the source. So, 12V switch > RCA and 12V switch > balanced, That would be even better to me. Has this been done before? Is there a reason not to?

second one for better launch plan, the product feature settled .

Suspect you may get better poll participation if members knew what benefit their vote might yield for customers.

Are you any considering any custom mix and match of channel output power in the future (notably for some of the bigger amps)?

Thank you for posting to listen to a rowdy bunch, like us!

Oooh!
How I love the idea of a back-plane bus; with distribution to eight (8) drop-in (plug-in) modules... AND user accessibility!
But why constrain such a nice design, dedicated solely to power-amp modules?

For prospective buyers, who may desire 5 or less amp stages; DAC and ADC modules can also populate any of the unused 8 back-plane interfaces (if/when).

Excellent idea: a housing for Hifi modules! Or HiPhi, with a nod to us (or them damned) "audiophiles"

Appreciate when designers ask consumers for input, but always turns into an episode of the Simpsons.

Ha ha, that can happen indeed!

If the designer listens well, he/she will find the (sometimes underlying) needs of these consumers. Some designers manage to limit this when it goes off the scale. Some manage to nip any good ideas in the bud, can not "read between the lines", only see technical problems instead of product opportunities.

We'll see where this is going to...maybe time for the designer to step in here? ;-)

A backplane distribution bus for power amps is difficulty level 1, the complexity involved in something that can handle preamp, ADC, DAC, DSP duties is several orders of magnitude higher - and would involve quite a lot more R&D... difficulty level 10!
The costs involved would rise proportionately - mostly due to labour in design, test, debug, develop associated software etc...

Not even an Intel Z890 motherboard (w/much onboard circuitry) is considered to be "difficulty level 10".
An 8-layer back-plane RDT&E needs no active circuitry, since the 'heavy-lifting' will be handled at the plug-in modules.

Because I tri-amp my speakers I voted for the PM256.

Please add a gain control per channel. Ideally this wouldn’t be a volume knob, but perhaps a potentiometer that could be adjusted with a screwdriver. The reason I like to be able to adjust the gain on my amps is two-fold:

1. I’ve measured several stereo amps (using an oscilloscope, voltmeter, dummy load, waveform generator) and found that none produced the same output voltage on both channels despite being presented with the same input. On some units the differences have been slight but in other units — of the same make and model — the differences have been fairly significant. Being able to set the gain per channel would enable the owner to level-match the channels.
2. I like to limit the voltage output by my amps to match the limits of my drivers. For example, I set the amplifier gain differently for my 100W/4 ohm woofers than I do for my 40W/16 ohm midrange compression drivers. I set the gain on the amplifiers serving the woofers so that they are limited to a maximum of 20 V RMS. I limit the amps serving my 8 ohm/40 watt tweeters to 17.9 V RMS and the amps serving my midrange CDs (nominally 16 ohm but actually closer to 11 ohm) to 21 V RMS.

Please continue to rate your amps for use with 16 ohm loads in addition to 4 ohm and 8 ohm loads.

Having a device like the PM256 with a gain settable per channel, a 12V trigger, and a consolidated power supply would be a real winner!

@3eaudio will there be a thread pre-sale?

 

[chaddawkins]

+1 on interchangeable aluminum (silver & black) face plates (ASR limited edition?)
+1 on led color selection via rear push button knob (off + adjustable brightness)

 

[moonlight rainbow dream]

As somebody both into active crossover DIY speaker design and multichannel audio, this is a dream product for me. I've been making do with old AVRs and HT power amps in the used market, but these would eliminate so much bulk and weight from my setups. The more channels, the merrier!

 

[pieterv1]

@3eaudio will the PAM152 and PAM252 definitely share the same chassis with the 3ch & 4ch versions? Would be nice to have a compact 2ch enclosure

Also can we expect some pictures of production samples sometime soon? Curious about the dimensions!

 

[3eaudio]

Currently we are running production and should be ready to ship to the Amazon warehouse before end of Jan, some samples will also be sent to Audiophonice in the coming days.

@pieterv1, they share the same chassis with a simple design and reduce production costs.

• 2/3/4 channel one : 260 x 265 x 90mm (including feet=8mm)
• 6/8 channel one: 460 x 265 x 90mm (including feet=8mm)

a little bit surprised PAM152 got 10 votes.....

Will you have a web page for them? (would be nice to see interior layout, etc...)

when can we expect the PAM152 on the Aliexpress store?

Don’t know if it will be easy or too complex but Will 2 channel amp have self DIY option to add additional modules on the chassis, since chassis will have always have space for it?
