**Power_nisse** · 06-22-2005, 08:48 AM

Hi There!

Ive been reading in this forum Very much.. Can never be to much hehe

Im gonna purchase a Carputer system within a month or two, after about 1 year of reading and saving money(student)

Im thinking of getting an amp now.
my question is about the input signal and what do you guys think about this amp look pretty good

!Branson!

0,05 % THD
LED POWER ON Indicator
Built-In Automatic Short Protection Circuit
Built-In Automatic Over-Load Preotection Circuit
Built-In Automatic Thermal Protection Circuit
Bridgable to 4-3-2 channels
Mosfet stage
2 ohm stable
Treble/Bass Control
Bridgable output stage
Adjustable In-Level
Output Impedance: 2 ohm, 4 Ohm or 8 Ohm
Input Impedance: 10K Ohm at LOW LEVEL INPUT
Input Sensitivity: Einstellbar von 100mV bis 1 V
Frequenz. Response: 10 Hz - 30 KHz +/-1 dB
Max watt : 4x 1200W / 4 Ohm
RMS watt : 4 x 120W / 4 Ohm
RMS watt : 4 x 240 W / 2 Ohm
Max watt Bridged: 2 x 2400W / 4 Ohm
RMS Bridged: 2 x 240 W / 4 Ohm
RMS Bridged: 2 x 480 W / 2 Ohm
S/N Ratio: 80 dB
Stereo Seperation: 50 dB
Size : 285*60*360 mm

Connections and cables i can manage etc, but what about the-->

Output from sound card --> Amp input
Input Sensitivity: Einstellbar von 100mV bis 1 V

1.Is the soundcard comatible with that output signal ?
Intregated sound car 1st then im gonna buy a Audigy card?

2. S/N Ratio: 80 dB, Have been googling a little and found out that it might be a loss of sound quality?

3. The Amp looks good

but does it sound as good?

What do you think? Any recommendation/comment is welcome =)

Overhere I never have heard yet of that amp...
But I already don't like them stats:

Max watt : 4x 1200W / 4 Ohm
RMS watt : 4 x 120W / 4 Ohm

With a good amp the Max power is less or around double the RMS value, with your amp it is 10x as much...
Probably just a brand trying to sell by it's "stats", it's not the only one, many manufacturers use the term "PMPO" (Peak Music Power Output) as a means for advertising!
Usually, the PMPO power is about five to ten times higher than the RMS Power, and tells you actually nothing...

Hmm ok, but i only look at the RMS wattage =)

Or is the Amp just crap maybe?
its a very low price aqtually 1600 SEK about 228 dollar and its quite nice looking too hehe

Well I can't say the amp is crap cuz i don't know that amp or brand...

But the "specs" and the prints on that amp do let suspect that they are trying to sell it not because of it's performance but cuz of it's "numbers"...

Which makes me always very carefull
