Why 24/7 warm-up period on amps?
if power is reduced by half is that a 3dB reduction or a 6dB reduction.I'm sure Kijanki will answer the part of your question that was directed to him, but in the meantime I'll state that if power is reduced by half that is a 3db reduction. That s...

09-14-11: Paperw8v_dB=10*log(v_out(f)/v_in(f))v_dB=10*log(1/2)/octavev_dB=10*(-0.3)/octavev_dB=-3dB/octavethat's the result; it's not subject to your opinion or my opinion, that's just what it is.As I said, you have a fundamental misconception whi... 
Why 24/7 warm-up period on amps?
What the equation means is that when voltage is reduced to half it's original value, power is reduced to one quarter it's original value.Yes, of course. I stated that in my post here.Hold on, this goes to my previous comment: you can't just cite e... 
Sub connection to CARY SLP-05 preamp
The Cary person provided excellent information. However, as I see it the information he provided makes the case for connecting via speaker-level much more compelling.Since the positive polarity xlr signal and the rca signal are common, if you were...

Kijanki, no problem with the beer. Thanks for your comment, which as I'd expect is totally correct, with P representing power and U representing voltage.Ralph (Atmasphere), just saw your post. Thanks also.Best regards,-- Al

Dave, I'll go with the beers and the music. Further explanation seems pointless. JeffreyBehr, thanks for your comment, which of course is 100% correct.Regards,-- Al 
Do you understand the words to the Mus U listen to
If the claim in this YouTube video is to be believed, that "here for the first time ever are the true lyrics to The Kingsmen's version of the song Louie Louie," it was 44 years before someone figured out what they were saying.According to this Wik... 
Why 24/7 warm-up period on amps?
Paperw8, let me supplement the reference I previously provided with this one, supporting my contention that db = 20log(V1/V2), rather than 10log(V1/V2) as you have claimed. It was written by someone possessing technical credentials that are utterl... 
Sub connection to CARY SLP-05 preamp
15K is too low to be ideal, given the impedance rise of the SLP-05's output to 3.4K at 20Hz. That is less than a 5x ratio. On the other hand, depending on the placement of the sub and speakers, the settings on the sub that you end up with, room ac... 
Why 24/7 warm-up period on amps?
Paperw8, I repeat. With all due respect your continued insistence that db = 10log(V1/V2) is completely wrong. Please do some further research.I could perhaps further support the credibility of my statements by describing my academic and profession... 
Sub connection to CARY SLP-05 preamp
Richard, as I indicated above my assumption has been that there is no output transformer in the SLP-05, that it is capacitively coupled instead (as is the case with most tube preamps). You might want to ask Cary to confirm that, and also to confir...

09-13-11: Paperw8the equation for dB measurement is:q_dB=10*log(q1/q2)where q1 and q2 are measured quantities and q_dB is the dB measurement for those quantities. when q1=q2/2, q_dB is -3dB.if you read closely the reference that you cited, you can...

Paperw8, on the 3db vs. 6db per octave question, see this.Regards,-- Al 
Why 24/7 warm-up period on amps?
Paperw8, what Rower30 is referring to is the fact that the capacitance of a line level interconnect will interact with the output impedance of the component which drives the cable, forming an RC low pass filter. The "R" corresponds to that output ... 
Why 24/7 warm-up period on amps?
Lev, your amp's power consumption is specified as 650W in "on" mode (presumably under no signal conditions), 130W in "standby," and 10W in "sleep" mode.If it is in "on" mode all the time, that computes to 0.65 kilowatts x 24 hours per day x 30 day...
