Heat Dissipation?

Nah - go into business selling them to audiophiles. You can make big bucks on something like this; charge $100 ea. for 4 blanks and claim they increase the sound quality if inserted between the amp and cd player. Use a tropical hardwood and claim special 'damping' due to the internal resonance of the wood fibers interacting with frequencies in a narrow inaudible band above 20khz. The resulting sound will be cleaner, bass will be crisper and the high frequencies will shine. scott (there's a sucker born every second) |

Heat Dissipation?
For sensitive gear I prefer using a push fan coupled with a dust
filter. Air flow generates a lot of dust bunnies and the more that you catch (using say, an electrostatic filter) the better. If you use suction then the dust has already passed over your expensive gear. |

This was one area I was wondering about. With the acrylic doors in the front, I can't envision any effective way to introduce any placed inlets. Can you add a gap between the front doors and the bottom shelf? However, as Leon has mentioned, maybe I'm worrying needlessly. It is a higher end Yamaha receiver about a year old and might not need the attention I'm focusing on heat dissipation. I'm not a sound volume freak running it at 3,000 decibels volume every chance I get. It all depends on the type of amplifier circuit and power supply. Many new amps use class D circuits, which are much more efficient (though often less accurate) than the old class AB designs, and so put out less heat. Generally you can tell by the weight/size of the amp...class D ones are usually lighter and shorter, while class AB amps are generally taller/heavier due to the large transformer(s) in them. Chris |

"Chris Friesen" wrote in message Can you add a gap between the front doors and the bottom shelf? Nothing that wouldn't look out of place. One thing I might consider in the future is fan assisted air input up through the bottom shelf with fan output somewhere near the top back of the unit. That type of air flow wouldn't have any effect on the aesthetics of the entertainment centre. ones are usually lighter and shorter, while class AB amps are generally taller/heavier due to the large transformer(s) in them. Going solely on that basis, it's an AB amp weighing in at close to 50 lbs. At least that's what it felt like when I was struggling to lift it in place. For now, I'm not going to worry about it. The entire back of the entertainment unit is open. If and when I get around to closing it in, I'll measure the temperature difference and decide then if I need to run some type of additional cooling assistance. |

Two things:
First (on topic, at least to OP): I'm surprised no one has mentioned this before, but why not get a thermostat controlled fan? You can get fans that only turn on if the temperature is higher that a threshold. So, what I would recomend: Install a thermostat controlled fan, near the top back of the cabinet, blowing air outwards. Install a hole near the bottom of the cabinet (slightly bigger than the hole for the fan), with a dust filter on it (don't forget to clean it every few months). This will keep dust out of the system, noise down when your not overheating, and the temperature down when you are. Second thing, off topic, but a personal crusade of mine: buy HDMI cables on-line. Having worked the past few years in the industry (specifically I wrote the HDMI firmware for high end TV's), I can tell you that in all normal cirucmstances (less than 20' cables, HDMI 1.3 certified cables for HDMI 1.3, etc), the picture/sound you get with monster cables is EXACTLY the same as the picture/sound your recieve for a $10 cable you buy on-line. Monster (and other brands) of cables give the retail stores really high margins, so they don't bother selling reasonable priced cables. I'm not sure if I'm more peeved by the fact that the retail stores think that I should be stupid enough to buy thier cables, or that there are enough people buying these cables at the outrageous prices to allow the retail stores to sell nothing but. Anyway, just had to get that out... phew... feel better now. John |

The same is true for RCA cable, toslink, subwoofer cable, speaker cable, etc. You can definately get cheaper stuff, but I've found that http://www.bluejeanscable.com/ has pretty high grade stuff (Belden/Canare cable, Canare/Neutrik connectors) at reasonable prices for what you get.

I've bought HDMI cables and audio cables and video cables at http://www.cablewholesale.com All cables were super cheap (half what bluejeanscable charges for HDMI) and very high quality. I would highly recommend them to anyone looking for any kind of cable. The web site works great, and buying is easy as well. No affiliation whatsoever, just a happy customer for at least 3 years now. -- Jack Using FREE News Server: http://www.eternal-september.org/ http://jbstein.com |
