Hands down one of the best ausio channels on Youtube. Great conten, Explaines clearly, Cheers

Excellent. I’m running a pair of sub woofers off a mono cross over and understand now that I should run it to the amp in parallel mode. Thank you

[jeffsaxton]

I just got one of these and am still evaluating it. I paired it with a set of 40 year old Realistic (Radio Shack) speakers. This is the first time these boat anchor speaks have spoken for 25 years. Sounds great! The only downer is that I'm getting some 60 Hz hum which isn't noticable when playing music. This is with nothing hardwired to it but speakers.

Hello, nice channel you have. For the Bridge mode there is a very important difference that was not mentioned. In parallel mono the same source is used to feed both amplifiers, for bridge mode there is a phase inverter that needs to be inserted between the source and the amps in order to split the signal in two with a 180 degrees phase shift between each other. Without this phase inverter, if you connect a speaker between the two positives of each channel the result will be the cancellation of the resultant signal and the outcome won't be the desired one but interesting to hear. I watched the video a couple of times before adding this comment and could not identify this detail in the explanation. The power amplifiers (some of them) have a control switch to move into bridge mode, so is an easy change for the end user but thought that know how bridge mode works at the input would be important too. Thanks for the tutorials and keep going. Regards.

I had not understood those terms and application until this- thank you!

Hey kyle i really respect to your teaching

[mariodquiroz]

I enojoy a lot your channel, weel explained and objective. Right to the point!

Isn't there some amps out there that actually connect both amp channels together pretty much completely, side by side, in parallel mono mode, effectively creating a SINGLE channel amp, but one that can supply TWICE the current at the same voltage, therefore ALSO doubling the wattage output capacity into the same impedance loads as in stereo mode? (Just only doing it then as a more powerful "monoblock" amp instead) (It seems like I've seen amps that do it that way instead of the way you described for this amp in this video... But maybe I'm just remembering it wrong?)(Have you ever seen an amp that does parallel mono mode in that way that I described above?)

seriously bro believe me u r the best ❤️
ur channel has everything what i was looking for

[jr.rasentertainment]

Thank you for sharing your experiences. Learning so much already. Watching all the way from Vanuatu 😀😁👍🔥🔥🇻🇺🇻🇺🇻🇺

[archiemacdonald]

love your videos 📹 very informative .I've got 2 power amps which I've never used in bridged mode .always a bit nervous about bridging them I use them in biamping mode with works for me many thanks for the this informative information 👍

[alexdebelen]

Can I port two 8-ohm speakers separately on Channel A and B and use Parallel mode? Is that safe for speakers? (I'm sorry I'm just a beginner)

TIPS:
1) Check amp mode, connections, leads & speakers before connecting cables & powering on.
2) Switching in & out of bridge mode should be done with no speakers connected or the power off (if possible). Check connections, minimum input level/gain, turn on, then increase the input level/gain/volume slowly (eg. take about 10 seconds unless you hear a problem). You don't want to be fiddling with dip switches & wiring while the amp is ON.
3) If you make adapter leads, add labels to indicate purpose & how each end is wired (which end for amp, which end for speaker when not wired straight through). Use different color tape than your usual leads so you can quickly tell the difference eg. blue for normal, red for bridged.

I love these amps that are very convenient for your talk . How about using an amp that most of us have like a vintage receiver or integrated amp ?

[glengatt]

I wish I knew these things before buying, I been told that I can't use 2 emotiva basx A2s to bridged them for one pair of speakers, the told me to bi amp them but that's not the same I won't get dubble power with bi amp but it's the only way I can maybe use them

[leandrusi]

So what happens when we PAN on bridge or parallel mode??

[kennethvillarosaarceo]

Wow I like this guide parallel mono left and parallel mono right

[utkalnetwork]

Please sir upload your video quickly I'm always waiting for you

[raffaelec]

finally I find the right answer of the bridge mode after I looking a thousand video ;
