I am surprised no one has mentioned this model. 8200 watts per channel @ 8 ohms 14000 watts per channel @ 4 ohms 11400 watts per channel @ 2 ohms This is the second model that Admark has focused on maximum output power at 4 ohms per channel. It goes to show the 2 ohms per channel community is not as popular as many might believe. Best Regards, ------------- Elliot Thompson |

Any internal pics? Any details of output device type/count, power regulators rating/count/type. Max current draw per channel @ 4 ohms? Some of us grown ups, are more impressed by these details, as opposed to Fantasy Island, 1khz output power ratings.  ------------- Global Depopulation - Alive and Killing. |

Assume max power output, 40-100hz, is actually 50-66% of published figures. This rule covers 99% of lightweight amps. ------------- Global Depopulation - Alive and Killing. |

No more information other than Admark's photo showing the actual amplifier on their test bench. Having too much power is not the problem. The problem is those who do not know how to regulate the power to their speakers. Back in the 1990's many said the Crown 5000vz was too much power. Surprisingly, the AD 80's power is not too far off from their AD 60 Model. My only concern is the voltage rails. Benching it would pose a challenge for those who don't have the proper resources for current capacity on a 4 ohm load feeding the amplifier a AC line source 240 volts. If the wattage is based upon crest factor at 4 ohms per channel, the continuous average would be around 10,000 watts. Only time will tell until Admark decides to make the amplifier (and the manual) available to the public. Best Regards, ------------- Elliot Thompson |

At an amp test years ago, Void Infinite 8 MK2, stomped all over ITECH8, at 4 ohm, playing Reggae across 4 Scoops, despite ITECHs higher rating, on paper. Admarks have proven to be substantial amps over the years, but just like all lightweights, don't expect them to truly provide the zillion watts output, they specify on paper. Just hope for 50-66%, as mentioned previously. ------------- Global Depopulation - Alive and Killing. |

My estimate was close enough. Published Specs: 236 volts output @ 4 ohms (Crest Factor) 13924.00 My Estimate: 14000 watts @ 4 ohms (Crest Factor) My Estimate was 10000 watts continuous average per channel on a 4 ohm load. The amplifier should hover around 9900 watts per channel continuous average based on the AD 80 Manual offered Taurusty on a 4 ohm load. Admark always used Crest Factor to rate their power. So expect less on Continuous Average Power. The Peak rails should hover around 360 Volts (Possibly 400 volts with no load) with minimum sag into play @ 8 ohms. Around 330 volt rails with a sag @ 4 ohms (Crest Factor). Around 280 volt rails with a sag @ 4 ohms (Continuous Average). The AD 80 is not Bridgeable. I don't recall exactly where the biggest Powersoft lies in their rails at the moment. But, I do recall it fell within the 300 volt range. This is a different league of amplifier and, you will definitely need to step up everything to get the most out of this amplifier. Amperage drawn from a 240-volt Line Source (Based on Published Specifications) 4 ohms Stereo Mode Continuous Average: 82.5 Amps 4 ohms Stereo Mode Crest Factor: 116.0 Amps Please. No, How can I use the Admark AD 80 on 120 volt line source questions  Best Regards, ------------- Elliot Thompson |

Anyone else thinking the AD80, is just 4x channel with each pair of channels bridged? Hence not bridgeable, and 2 ohm figures < 4 ohm figures? I'm also thinking, this is way too much heat, power, packing density, for 1U. The AD42, is well respected, and fairly proven. ------------- Global Depopulation - Alive and Killing. |

| Yea ive had my eye on this ever since they released the teaser on their facebook page, had a price somewhere that it was 870$ ish dollars (I'll believe it when I see it) but before that my "dream" ideal upgrade amp was the admark ad-406, mostly because its galium and could squeeze out the last juice from a 20amp circuit but I very curious if from a purely sound quality perspective, is this going to sound better than previous crown/qsc/thomann or just gobs more powerful, at the risk of reliability... sounds like cvr might still be the way to go, there's less cap density on the 406 and it might be the better choice for my application even if its not as upgradable. Still like I said sure I mean personally wattage wise I'll be electrically limited before im amp limited so SQ is what I'm really curious about, some people say admark sounds better than cvr but they look the same inside. ad80 I think has some design improvements that might help with packing all those caps into a 1u but I don't want to gamble until others have gone before lol |

Morning the AD 60 is the only Admark model I would never buy for sub duty. 2x bridged 430 modules plus less caps. When I saw the 80 & realized it t was not bridgeable I hope the change in form factor (2U) will now replace the lost caps & upgrade the cooling… Need to see one opened. As it stands, the AD42 is still the best choice IMO where speaker power handling matching & best use of rack space is concerned.

I just ordered 4 AD442s… but I did go via Alibaba in the end as the currency conversion (you pay in USD) on PayPal is shocking… made about £10 difference even after the discount they offer via WhatsApp - with a small ampunt of reassurance the Alibaba platform offers.

"I can say the majority will not have the resources to power this amplifier properly." Undoubtedly.

My circuit can't handle much more the fulode is the cheapest GaN I could find, has had favorable reviews.

I have two problems with this. First is the look. Why the hell do they made it to look like Powersoft. I aint buying anything that looks like Powersoft but it actually isnt. Second. 14KW at 4 ohms is a lot of current for a Speakon connector.

powercons are rated at either 16A,20A, or 32A likely to correspond with common breaker ratings, rather than to reflect their true maximum current capability. As breakers can pass much higher currents for short periods the powercons will be designed to pass those for the specified time. |

Interesting indeed. Sinbosen's amplifiers has always had a strong Home Theater Market following from the days of the Lab Gruppen copies. Their marketing concept appears to be focusing heavily on Frequency Bandwidth (amongst other things) due to the GaN Topology. I am reading many are praising the Admark AD 42 over the Admark AD 60 despite, the Admark AD 42 offers no GaN topology whereas, the Admark AD 60 and, Admark AD 80 does. So while GaN does offer more benefits than amplifiers offering non-GaN Topology, in the Professional Market, it does not seem to be what many Americans call "A Game Changer" causing an overwhelming difference in the end results.

probably a 3mm2 power cord (that's what's on my biggest sinbosen) or possibly 4mm2 - so got to be a 32A breaker at most I would have thought. But you would really have to push it to trip a 20A D-type (or blow a 13A fuse). |

That mains plug is a bit worrying. Probably illegal to import into the UK like that. And a 30 amp plugtop fuse surely doesn't meet BS1362, so it's falsely marked. (For the benefit of our friends in the USA, all British 13 amp plugs are fitted with an internal fuse, but 13A is the maximum allowable size) This doesn't inspire much confidence in the product or its manufacturer...

Even though the above is, basically true, my feedback from exhaustive research, of the "AD42s with non GaN devices", is, they are pretty much the best of their kind from China, and many Reggae dudes in US, Caribbean, have directly compared them to Powersoft K20s, in real gigs, attached to generators, and are very impressed with them.

Even the sales guy said the plug is inadequate and should be changed, anyone using these as intended would change the plug - but at least it’s handy for an initial test (for me at least)… I can look past the obvious safety / legal issues in how they are delivered. In tests they pull over 30amps, bridged just before clip - and do deliver the rated power for around 2.5 seconds - sinewave signal… they then drop to around 3.5k per channel into 4ohm… music isn’t a sinewave, and all class D amps behave like this and are rated the same way… behaves as I would expect. Listening test so far - just running 2 x WS218X on 2 channels (2 18s per channel @ 4 ohm)… and compared to the Blue Aran Q10s I was using… and this is of course subjective… the bass is much rounder, and feels a lot lower somehow - the Q10s had a hard edge to the sound - loud but almost digital / choppy sound to them… overall I’m happy with the change and confident they deliver more than enough power to get the most out of my boxes. The Admark gets the cones really moving, and I have only lit 3 of the signal LEDs so far… headroom for days in my use case. To get this amount of power from name brand amps would cost 4X or more.

Amps installed in their new homes… obviously PDUs now need to be swapped out for a larger version. The FFA 8004HDs are on mid-high duty and I’m also happy with them over the Blue Aran B8s I was using - very clean sound, lower noise floor.

Using the AllDSP and running 21" drivers I found that putting a 5s attack compressor and some dynamic eq on the tuning frequency of the box for when the cone isn't moving much, the average power consumption was only about 20 amps. The right D type breaker will take several times rating for a few seconds. Played some really heavy jungle hitting the compressors and it still sounded great. They are designed with a good balance of peak vs average output for real music. Even the biggest voice coils are only taking 600W average real power and have significant thermal mass. |

Penn Elcom distro- but not big enough for this combo of amps - need to replace. And yes, you are correct on the fan flow, which I didn’t even think to check before purchasing, and I have almost cooked amps like that before - but it was a berry ep2500 and I wasn’t that worried about the warranty, so I just flipped the fans around in the case, which solved the problem and it never had heat issues again. I’m bit more cautious of doing that with the FFAs… my plan is to make some kind of air guide at the back of the rack… Once I swap the distro there will be a 1U gap between the Admarks and the FFA - which is the space I will use for the air guide. Hopefully that will keep it under control - bloody annoying though.

Ordered a Powercon plug (NAC3FXXB-W-L) to test if the wire will fit, it does, but it’s a tight fit, which surprises me as it the spec sheet for the plug says 2.5mm max, and the wires measure 4mm - but heyho, they are rated to 20amps, and I think that’s will cover my use - will see how we go. Hopefully the thermal trip switches on the Penn-Elcom PDUs are happy with short peaks over 16amps per bank if ever required (changed to the 32amp PDU with 8 powercon outputs - split into two banks, with a max load of 16amps per bank).
Had an exchange with Dave at FFA regarding fan flow… he said it’s unlikely to cause any issues. I’ll still be making some kind of air guide to direct the exhaust from the AD442s down and away from the FFA intake. To be fair, even after a few hours use, the air coming out of the Admarks doesn’t feel hot, or even heated… but not given them truly hard use running all channels at 4ohm yet. |

| apologies if you've considered this.. but are you measuring wire diameter, when the figures given on cables are for cross sectional area (mm squared)? |

Maybe we should consider, how many output devices, are in the AD80, and physical current draw/storage capacity of the PSU(s), before reading too deeply into published specs. ------------- Global Depopulation - Alive and Killing. |

Which is why I'm on the fence regarding the AD60, and AD80. ------------- Global Depopulation - Alive and Killing. |

just got one of these which will run a rack of 3 amps and link to another rack of three amps. https://www.thomann.co.uk/botex_psa_322_6_dl.htm" rel="nofollow - Botex PSA 322-6 DL – Thomann UK the 32A on the back can be turned upside down so that the flap doesn't go higher than the top of the unit. RCBOs are 16A C-type. Incomer is 6mm2. Internal wiring seems to be 4mm2 and 2.5mm2 so should be okay to swap some of the breakers for 20A D-type if needed. Might see if I can mount something more useful in the schuko socket cutouts. |

The AD 80 is too new to receive concrete feedback from end users. The AD 60 is optimized for 4 ohm per channel stereo. For the user that must use 2 ohms per channel, the AD 60 will not fit their requirements. For the user that will never use 2 ohms per channel, the AD 60 gives you the most power for your dollar @ 4 ohms per channel in the entire Admark line that offers a model number lower than the AD 60.
