Lol where have you been digital amps do in fact existhttp://www.alpine-usa.com/US-en/products/series-c.php?category=AMP

welcome to the digital world

oh and panasonic have been making digital home amps for years

Its funny how many of you made fun of some for saying digital amps, when you were all wrong for thinking they dont exist

They are NOT digital amps. Thanks for playing. The marketing department can call them whatever they want to, that doesn't mean that they are in fact digital. They are full range Class D switchmode amps. People assume (and marketing departments capitalize on) the "D" in Class D means "digital." It doesn't. It was just the next letter in line after Class A, B, and C. The signal going in and coming out are analog. The signal is at no point run through an A/D converter, processed and then run through a D/A convertor. You can't amplify digitally. It's an anlog function.
Before you start acting all high and mighty, know WTF you're talking about, as it is you don't have a clue.

I have no idea where this thread is going.

i'm afraid i know where:spank:

Amps that switch back and forth digitally are considered digital amps. Maybe not what you want to say it is in your little so called life. The OP asked about digital amps. Well these are digital switching amps, they are called digital amps.

class D yea. With a digital switching output = DIGITAL AMP

Here is one of my old Tsunami's that said "Class T Digital Amplifier"

i knew one was coming soon.I've owned avionixx and altomobile amps. http://www.tripath.com is the chip used in Tsunami, Avionixx, Crystal, Zapco and others.

Helotaxi has explained this to me before in terms I could grasp.

I sat back not wanting to say anything, but now your are wrong again. Digital amp's do not exist. Maybe he meant an amp having a digital readout such as the MA Audio HK401SX. B4 you post actually READ what you are reading, instead of going by a manufacturers lingo to the consumers.

how about the kicker sx series. it is digital and i have two of them

no, they're not.

they're not switching "digitally" anyway. The pulses contain a component of time - that fact alone is NOT digital.

They can call them pepperoni pizza amps if they want, that doesn't mean they'll taste like pepperoni pizza.

They're CALLED digital amps because marketing depts. know that a lot of people are stupid (I wonder which people those would be //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif ) and will buy most anything if they believe it's "digital".

FOR THE LAST TIME THERE IS NO SUCH THING AS A DIGITAL AMP!!!

If you want to call a switchmode amp anything, call it a binary amp. The output devices are on or off not some inbetween state like a normal linear amp. The switching might be controlled by a DSP chip, but that does not make the amp digital, and nothing you say will change that incontrovertible fact.

Class D amps sample the input and switch the output at a fixed rate. Nothing digital about it. I can be done with no DSP at all. Adding a DSP chip still doesn't change the fact that an audio amp is definitionally an analog device.

Class T amps use a DSP chip to vary the switching freq based on the freq being reproduced. The switching freq increases with freq to increase linearity at the cost of efficency. With only lower freqs present, the switching freq is decreased and the efficieny goes up.

Once again shorty, you don't know WTF you're talking about. Until you do, STFU. You can call something a name but that doesn't mean shit for functionality. There is nothing digital about amplification and any name you put on it isn't going to change that.

So - regardless of the brand or the specific gear in question all the term "Digital Amplifier" is good for is marketing?

Much akin to the garish splashing of MAX POWER 1600 WATTS found in various neon day-glo hues on lesser-quality amps?

Absolutely - ignorant people need to be beaten into submission at every opportunity.

The amp I bought to hold me over till can afford the zx amp was a "hybrid digital" or at least thats what the box said. It was extremely small for the power it supposedly put out. I think it was a swiss audio amp. Anyway for a temporary fix it worked just fine.

my digital amp is really powerful. one time, i think i heard a 2.

SM amps are just a huge class. pretty much a counter example for every conventional piece of wisdom. You don't actually need to transmit just 2 levels for instance. you don't need to transmit square pulses either. don't need PWM. huge class of amplifiers.
