Amplifiers With The Same Boards?

[dennisthamenace 10+ year member]

I have a question about amplifiers with the same boards.

. Kole Q1-3000D

. O2 Audio OAD3000.1

. Planet Audio TT2250d

. Planet Audio VX2200D

On realm of excursion they say it has the same board as the power acoustik a3000db. Now im confused, does this mean its pretty much the same amp and i should expect the same power coming from it. Or are there other factors that come in to play in terms of output that i should know about?

yes just because the traces on a board are the same dont mean the components are the saem....

may have larger or higher tolerance capacitors, resistors, or transistors

sometimes, than again theres some amps identical part for part except for the case //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

If they have the same boards, they will be the same amp. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

While its technically possible for a company to exchange parts from the original BOM to higher quality parts, its not economically feasible. Think about it, the reason they are all the same board is cost savings. You want something, just find someone who makes it and stamp it with your brand. It doesn't make economic sense to then go in an change the board, even though its possible for small runs.

The board only dictates the layout of the circuit. It doesn't mean that the components on the board are the same in tolerance OR value. Amps of the same architecture have pretty much the same layout. It's the components (resistors, transistors, capacitors, etc...) that actually determine the specs and performance of the amp from there.

Perfect examples were the old Orion and Phoenix Gold amps (late 80s early 90s). The PG MPS-2500 and the MS-2125 had the same board. The amp specs were totally different though, because the components on the board were different. Same for the MPS-2220/2240 and MS-250/275. The Orion HCCA225 was the same board as the XTR275, the HCCA250 same as the XTR2150 and the HCCA2100 the same as the XTR2250. A lot the modern apps mentioned are built off a 3rd party generic board and the company whose name will be on the final product will spec the components on the board to make it their own. No different than RE or TC Sounds or Image Dynamics using their baskets and motors to make subs for several different companies. The soft parts and thus the final specs of the subs are totally different even though the frame and magnet look the same.

wow ignorance at its finest. You sir have just made my day. Economic sense eh? Yea it does not make economic sense for someone to develop there own board. However it does make sense for a company to take a 1500 watt amp "board" and put parts with tolerances from a 2500 watt amp and have a 1500 watt amp that does close or above 2000 watts //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif.

Of course amps with the same board are the exactly the same.

Just like how subs with the same basket are the same sub.

EVERYBODY knows that. Stop being a bunch of n00bs.

just like the q and the mag are the same sub DUHHH

if you've ever looked at it, many electronics have PCBs where only half the parts are loaded. such boards may not even have a design that uses every component laid out for the board. this means that features can be different as well as performance.

There is famous pro audio company that has different models of amplifier

and different power categories so people have a nice selection to choose.

I analyzed their designs.

It appears they made one reference 'flagship' design, lets call it 'Amplifier X'.

X amp series consisted of many models, lets call them x01, x02, x03, x04, x05.

Those different models use the same PCB.

They subtract parts from the X amp reference and scaled down the design

according to output power.

X series is the flagship.

For the medium grade amp lineup, they took the X amp design and didn't populate some surface

mount electronics to remove some signal processing ability. They did some very minor capacitor tweaks

also and from this created a new line up, lets call it the Y series amp, with varying models.

This is a clever design because one PCB is all you need and this saves alot

of money that is not really passed on to the consumer. They charge premium

for X series because it's the flagship and they charge less for the midrange lineup.

The company can make more profit and these amps will be still 'made in the USA',

otherwise if each design was unique, it would probably be sent offshore.

.... then last year they introduced version 2 of the medium grade amp. Lets call it Y series V2.0.

They added a few things and changed the chassis design. Viola, new amp. hehe
