This 2U amp claims 4*5400W into 4ohm. has DSP. four separate output boards rather than one board. Does this look like it would do better on bass than the 1U Admark/CVR/Morin K-series clones? |

the cable does look undersized but it's a powercon, not a captive lead.
 think the text next to the powercon says 3000W |

Admark AD42, as reviewed by quite a few Reggae dudes internationally, is reported to output slightly less power, 4x 8 ohm drivers per side, than a Powersoft K20, but sounds, much much warmer. That is is a high bar to reach. ------------- Global Depopulation - Alive and Killing. |

I don't know why they have to make it look exactly like a D&B amp, given no D&B user would buy a clone amp and a non-D&B user wouldn't buy a D&B amp. I do welcome the idea of using 2U and allowing for proper heatsinking, decent sized transformers etc but they could have come up with their own generic styling.

After seeing the Sanway FP14K, fail to drive 1x PD1852 on 1x channel, as well as a QSC RMX 5050, I would never touch any Sanway lightweight amp, again. I've also seen a Sinbosen dual transformer "20K" lightweight 4x channel, thermal out, trying to drive 1x 4 ohm 18NLW9601 per channel. Put two of those drivers per channel, of a Void Infinite 8 MK2, and I was utterly shocked, at what I was hearing the amp do. After these experiences, "Personally", I just don't rate any cheap lightweight amps on sub, except Admark 2x channel models.

| I suspect it's made by Sinbosen or a third party, not Sanway. FP14000 is a class TD Lab Gruppen clone sold by many different companies. TD has a reputation for not being great on bass and the FP series is now 20 years old. |

I should really say, "I reserve judgement" on any cheap lightweight amp, until I hear it drive 1x "8 ohm" driver on 1x channel, compared to QSC RMX 5050, or hear how a 2x channel amp, deals with 2x 4 ohm drivers per channel, compared to Void Infinite 8MK2. I mean, the point of a "big cheap lightweight", is to replace hefty old Transformer amps, right !? Something must be really wrong, if a lightweight amplifier rated at 2350wpc @ 8 ohms, can't better transformer amp rated @ 1kwpc @ 8 ohms. ------------- Global Depopulation - Alive and Killing. |

Sanway has already implemented a clone that, follows the same principal as Admark, and, Morin (in addition to others out in the market sold on Alibaba) with their DA43K2. https://www.china-sanway.com/DA43K2-17200W-Gallium-Nitride-class-d-audio-power-amplifier-for-subwoofer-pd598208078.html" rel="nofollow - https://www.china-sanway.com/DA43K2-17200W-Gallium-Nitride-class-d-audio-power-amplifier-for-subwoofer-pd598208078.html The model you posted seems to be aimed at those that want more flexibility with DSP than just Raw Power. https://www.china-sanway.com/D80-16000W-High-Power-Class-D-DSP-4-Channel-Power-Amplifier-for-Line-Array-Speaker-pd547689648.html" rel="nofollow - https://www.china-sanway.com/D80-16000W-High-Power-Class-D-DSP-4-Channel-Power-Amplifier-for-Line-Array-Speaker-pd547689648.html Best Regards, ------------- Elliot Thompson |

| AD42 weighs 12kg. D80 weights 18kg. That's more of a middle weight than lightweight. Would hope some extra oomph came with that weight. |

Do you have any friends that you could borrow an AD42? You may be underestimating what this amplifier is capable of doing. You could get the Sanway's version (DA43K2) if you rather not buy the Admark.
Either way, the amplifier can deliver nearly 6000 watts per channel @ 4 ohms continuous average. Unless you are using speakers that offer a 3000 watt Program Rating, you should have more than enough power (Headroom plus Burst Ratings from the amplifier) to not worry about having a Dynamic Equalizer at your disposal while, driving your woofers to/beyond their limits.
As you start using a lot of power that can over power your loudspeakers, you won't need a lot signal processing anymore.

i've got CVR d2004, sinbosen D4-3000 and, and a four channel morin, but not a 2 channel like the AD42. the highest power admark is the AD60 which is a four channel amp inside with the channels bridged. my subs are double 21" B&C 21DS115-4. tried running one driver per channel off the D4-3000 which seemed to be pushing the drivers near excursion limits. |

The Admark AD 42 and, AD 60 were benched sometime ago. The differential among-st the two in terms of dB is + 0.44 dB in favor of the AD 60 at 4 ohms per channel continuous average. So, from an audible standpoint, we won't hear a difference among-st the two in terms of loudness.
Comparing any of the two against the Sinbosen D4 3000, would offer a +2.34 dB to +2.78 dB in terms of loudness over the Sinbosen D4 3000 at 4 ohms per channel continuous average. That is an audible difference providing the loudspeakers will not proceed into power compression even if, you try to rectify the excursion limits by rolling off some of low frequency extension.
There are times when power is the limiting factor when wanting more SPL from your loudspeakers. Other times, it is loudspeaker limitations, if you want to achieve a particular frequency, at a given SPL in which, the loudspeaker cannot deliver such levels, without the aid of multiple loudspeakers working together in unison.

if the d4-3000 is bridged the spec says is delivers 2*10,000W into 8ohm and 2*13,000W into 4ohm. Which is greater than the AD42 or AD60 spec. or if you run four 4ohm drivers off each amp you have to compare the d4-3000 output into 4ohm against half the AD60 output into 2ohm There is a newer d4-3500 which is even more powerful. |

If you are using the D4 3000 in Bridged, then there is no need to look at the AD 42 or AD 60. You would be stepping down in output power/dB/SPL. Moving from an D4 3000 to a D4 3500 would only achieve a +0.07 dB in audible output. Definitely, not worth the investment in your case. Might as well wait until an amplifier is introduced offering 26,000 watts per channel in your case to hear a +3 dB difference. Bear in mind, if you are using the D4 3000 in bridged mode, you will be pulling nearly 50 amperes per channel at the loudspeaker outputs continuous average @ 4 ohms. So, don't forget to step up on the cabling to eliminate any transmission loss. Best Regards,

This really is it... Many people are saying it is 2nd only to the Powersoft K20. Admark AD42 is the first "cheap" chinese lightweight, that I even considered for "4 ohm" use, playing Roots Reggae, with a pre-amp. If I had the choice between this and an MC2-E90, I would choose the Admark ------------- Global Depopulation - Alive and Killing. |

Date Posted: 18 July 2025 at 6:46pm
Maybe, but since when is how recent an amp is, any guarantee of build quality !? Like Elliot said, borrow an Admark AD42, and try it, as it is the current budget 1u reference sub amp. ------------- Global Depopulation - Alive and Killing. |

Just saying the AD42 isn't news to anyone, least of all me. I've already got higher spec amps that I purchased in preference to the AD42. maybe you should try the ones I have mentioned. And I really want to stick with four channel amps and use the same amps for mids, highs and monitors. |

I am referring to your Loudspeaker Cable. Using the Sinbosen D4 3000 in bridged mono, the output current, from the amplifier to loudspeaker, @ 4 ohms per channel, passing through the Loudspeaker cable, would be nearly 50 Amps per channel. Using a loudspeaker cable that is not rated to manage such current continuously, will offer Transmission Loss. Best Regards, ------------- Elliot Thompson |

D80 weighs in at 25kg according to the Sinbosen website. Certainly not a lightweight, at least not physically. A 3k consumption coupled with a 20+k claimed output might say otherwise on its bass performance though!

Posted By: snowflake
Date Posted: 21 July 2025 at 3:47pm
I have had an email back from Sinbosen confirming 25kg is a typo and it in fact weights 19kg as it says on the Sanway site. amps don't supply their rated output due to crest factor and duty cycle. a Powersoft X8 or a Linea 44m20 says it only needs a 20A supply which is 4.6kW. Circuit breakers will supply transients of several times their rated current. |

If that is a genuine DFM DSP module inside (which i doubt) it should have IIR, FIR, DYNEQ, Speaker library ... all the top notch gadgets and with 96KHz sampling. I got one Lacoustics clone amp to test and the DSP was sort of crippled cpoy of DFM with very limited functions. ------------- Marjan Milosevic MM-Acoustics www.mm-acoustics.com https://www.facebook.com/pages/MM-Acoustics/608901282527713 |

Hello! How about other version ie AD30 & AD35? Are they equally good? Don't need power output that AD42 offers!

Don't make the mistake of believing all lightweight amps, completely meet specifications. Just buy the biggest amp you can afford, Often the older/previous Admark amp versions are not available. Also, the AD42 has much needed upgrades, that make it superior/more reliable than previous versions. I've heard mixed feedback about the Admark K30, K35, only heard good things about the AD42.

the D80 amplifier is no longer available through Sanway. Only places still listing it have it at $1800 which makes it only really worth it if you specifically need a d&b D80 clone. |

I have mate in West London, prob 1/3 electronic engineers in London, who specializes in servicing/repairing these. He charges £600, to overhaul Admark amps, fixing manufacture shortcomings, upgrading cables where needed, replacing solder joints where needed. He has well known Reggae sound, used to design and build his own transformer amps, previously owned Powersoft K20.
He now has Admark on Mids and tops. ------------- Global Depopulation - Alive and Killing. |

here's another shot which shows slightly more of the internal. Spec says it weighs 20kg so it's not just a lot of empty space inside the case. Can't see the value of the caps but looks like substantially more than you see on some other 4 channel amps. |
