| Running Benchmark AHB2 in bridged mode and 4 Ohm Speaker 40 amps of current is needed to produce 40 volts peak (100 watts RMS) across a 1 ohm dip in impedance. If this impedance is reactive the amplifier will be really unhappy.I don't understand it. 40V across 1 ohm (or 40amps thru 1 ohm) would make 16... | |
| Running Benchmark AHB2 in bridged mode and 4 Ohm Speaker Here you go: Page 26 "performance plots" fig. 1, 2, 3https://cdn.shopify.com/s/files/1/0321/7609/files/AHB2_Manual_-_Rev_G.pdf?6581480924542235084These plots show almost identical THD at 4 ohm, 8 ohm and bridged 8 ohm max power. As for damping fac... | |
| Running Benchmark AHB2 in bridged mode and 4 Ohm Speaker Quote from instruction manual:The AHB2 power amplifier can be run in two modes: STEREO mode - Two output channels MONO mode - One output channel in bridged mono The bridged MONO mode will deliver almost 4 times as much power into an 8-Ohm s... | |
| Running Benchmark AHB2 in bridged mode and 4 Ohm Speaker I have AHB2, few month old. In instruction manual rev G p.22 it states: Output Current: 29 A peak into 1 Ohm, both channels driven The same is on their website (it used to be 18A). Perhaps they improved power supply (higher limit). | |
| AirPlay streaming question please Ian, one problem you might encounter with Airport Express is slow DAC syncing. Computers transfers just plain data to AE and the clock for this data on Toslink out, is created first time by AE. During gaps in the music there is no clock and DAC... | |
| Looking for fado music that is well recorded. If you like Portuguese Guitar then get this record (samples on Amazon):https://www.amazon.com/Guitarra-Portuguesa-Carlos-Paredes/dp/B001232MGY/ref=sr_1_2?ie=UTF8&qid=1... | |
| Looking for fado music that is well recorded. Fado classics, like anything by great Amalia Rodriquez will be poor sound quality. I like Ricardo Ribeiro (try Porta de Coracao) and Antonio Zambujo. Both are great, but Ribeiro is considered one of the finest fado singers of our generation.http... | |
| highest damping factor amp Back EMF causes current flow in opposite direction to one that would cause motion of the membrane in given direction. This current will produce force moving membrane in opposite direction - braking movement completely, like shorted motor. Except... | |
| Ohm alone, on the phones. It can only make it worse IMHO. If the hiss comes from the output stages then lower ohm ratings will make it worse. Hiss coming from the input stages will appear the same, since volume control won't change signal to noise ratio. | |
| ... how important is Damping factor in determining what amp to buy When a signal is sent to a speaker to play a note, the cone vibrates. When the signal stops, the cone is still moving back and forth. and is an electric motor. This movement sends the electrical signal back to the amp, and a highly damped amp will... | |
| WD 40 to remove scratches on vinyl ! My friend's daughter "cleaned" his LP collection with a pumice stone. Your WD40 idea comes close. | |
| Liquid Amps Here is excerpt from Absolute Sound Paul Seydor review of my amplifier Benchmark AHB2:Because accuracy allied to absolutely reliable performance is the goal of all the Benchmarks, they are not products that tend to attract cults or other sorts of ... | |
| Is USB audio dying? Are there any inherent advantages to handing off audio to the dac via USB?Asynchronous USB has the same advantage as Ethernet or Wi-Fi - making internal DAC clock completely independent from computer clock. In contrast S/Pdif transmission is pro... | |
| The Best Apple AirPlay Streamer Intone, thank you for the post. I have first generation AE for a long time. I just ordered spare one (MC414LL/A) from B&H (Apple Store is sold out). | |
| Best speaker/system piano concerts "Personally, I do not like what warm sounding equipment does to the sound of a piano. Warmth is wonderful on vocals, guitars and certain instruments, but it beats against the stretched overtones of a piano. The overtones in a piano occur at slight... |
