It says 2" above, but what about the back?


And, do I count the back space from the back of the case or the terminals?

(The cabinet is shallow, so every bit helps.)


The cabinet has the doors removed for air flow (and I can overhang the front knob of the AVR.)

Plenty of room on the sides, 7", if centered.


The shelf above is 1.5" shorter for air flow.

The back of the unit has a 1" vent all the way across the bottom (where AVR would be).


Right now, pending my other thread, it looks like I will have 2.7" above and 3.6" or 3" behind the AVR (depending how it is determined).


Am I okay for an HK340?


(The few others that might work are not that good. And I know I need a new piece of furniture.)

Depends on how long you play it. If it gets hot I would consider another place.

4 Inches is the proper vetilation space all around required for any avr unless you like throwing your money away and don't know how to care for your gear.

 

[QZ1]

Obviously, I care about the electronics, that is why I am asking. And, I have read variable requirements depending on brand, anyhwere from 2"-8" required. I am trying to get specifics from HK owners with possibly similar furniture.


With the front of the case open, it is much cooler, so this should lessen the other sides requirements. Regardless, I would like to follow the minimums.


To be clearer about this furniture:


Front: Open

Sides: 7"

Top: 2.8" (Shelf above is 1.5" shallower to vent.)

Back: 3.5" from case (Back has 1" H vent all the way across.)


Room temp doesn't exceed 75 deg. F.


Any other opinions?

The temperature of the AVR depends upon multiple factors including..
1. How loud is it being played?
2. How long is it being played at loud volumes?
3. Brand/model of loudspeaker, 4 Ohm & Low sensitivity put a higher demand on the AVR
4. Type of source material, movies or music.. Rock, classical..

Was that really necessary? Seemed like a reasonable question to me.

1. Compared to other people, not loud.

2. Won't be on more than 3 hours and not loud, as I said.

3. Polk RM 7400 & 6901 or Infinity TSS 4000 & 1100 (possibly Mirage OmniSat v2) (each one is 8 ohms) (5.1 config.)

4. Vast majority for TV programs and movies. Rock Music might be daily, as well, but would be much less time.


Now what is the magical formula to add my aforementioned ventilation specs to my usage to calculate if it is ok?


Seriously, though, I don't know how to judge this, at least with my DVR, there is a temp. readout so I could move it, until I get new furniture; not that the approval factor would be good, but so be it. With an AVR, I don't think it has this?

To get more ventilation into my cabinet I removed the back panel, which was just 1/4" ply. I added short pieces of steel angle attached to the back edges of the sides, bottom and top @ the corners on 45* angles to brace the cabinet.

Well....OK..

But to answer the question..

We need to know the specific temperature range the AVR gets under your typical operating procedure....

The internal AVR temperature should go no higher than 70 degrees C for its crucial components such as output stage and power supply..

Without sensitive measuring devices, one can estimate this range roughly

by playing the system in your typical manner and after at least 45-60 minutes put your hand on the center of the top cover..

It should be warm but not too hot to touch..

If it is hotter where you cannot keep your hand on it, you need to had ventilation clearance, additional cooling and/or turn it down...
