I'm curious about one thing though : does the 622 ever automatically power down its fan and/or hard drive when idle, like the 50x series do ?


I believe I remember a menu on the 622 that allows it to power down after 4 hours of inactivity...

The inactivity setting places the unit into standby. The 921 had this feature but from what I can see, the 622 adds the ability to inactivity duration. As for spinning the disk down. not sure.

With the 921's inactivity setting feature, neither the fan nor the hard disk power off. It is useless.
How quiet is the standby mode on the 622 ? On the 508 it is exactly the same as when the unit is unplugged from the wall - dead quiet.

Actually I believe the 921 inactivity feature was added to place the unit in standby so it can reboot in the middle of the night. I would not consider it useless, As to noise, my friend just got his installed on Sunday maybe I can have him take a reading and compare to my 921 in standby mode.

I will see if I can get some numbers to compare if my friend has a noise meter. We are starting to wonder off topic here so if I he does I will post the results and move the our posts to a new thread.

Ok. I talked to my friend and he did indeed get his 622 on Sunday. He know has 3 dishes instead of two and it sounds like the DPP44 is in short demand. In anycase, since he had a sound meter I asked him to check the sound at both the front of the unit and at the exhaust. Asked him to take reading a few inches from the box.

The readings were

56db on the fan and around 50 db from the frontt.

As a comparision I did this with my 921 and got.

63 db on the exhaust and around 60 from the front.

He did make a comment that the 622 was silent compared to his 6000 and could not be heard when the cabinet door was closed.

Though this is not the most scientific of test , It provides one data point. Irony is I got my sound meter about a year ago after borrowing his meter to configure my HT sound system.

It's so nice to get up in the morning and NOT hear my old 6000 whining away. :D

Thanks, interesting data. Now, was the noise any different when the 622 went into standby or not ?
I don't have a cabinet to put the 622, or any of my 9 HT components . They would overheat and die if I did . All of them are dead silent except the dish receivers. My 508 went into standby since I canceled my dish subscription and is as quiet as if it was unplugged . The 921 is quite noisy however, and I wish it would turn itself off when not recording OTA.

Except I almost only watch TV in the middle of the night (it has to be dark for the projector's picture to be watchable, and I'm a night person), so the 921 never gets to do its reboot. It shouldn't have to, anyway.

My receiver sits in the open on a glass shelf under the TV, not inside a cabinet. I don't hear anything from my 622 when it's in standby.

I agree with you it should not have to reboot nightly.. but that is for a different forum and different thread... I also stay up late and with a 4 hours of inactivity before standby it does not help me either. However, just because it does not help me with my use case does not mean the feature is useless in my opinion. Just not useful for me.

I believe I have read some comments that one can adjust the standby period and update periods so that those to features are more useable to late night folks.

Yep. Easy to configure when the updates will be done. I have my ViP-211 set for 7am.
