Whats diff between. Ht bypass vs using a passive connection-unity gain


Some preamp manuf adverise ht bypass, and some say u can use a passive output(unity gain).

whats is difference in terms of connectivity and how wiring is handled inside preamp?

Freya does not misrepresent itself. Neither does Schiit misrepresent the Freya.

This site has nothing to do with Freya.

You did not perform proper research. Own your error.
integrating a highend tube preamp into ht is a nightmare!

That depends on the preamp. You have to understand that the preamp is not designed to be part of the signal path.

Either the preamp has a HT feature, or it doesn't. If it doesn't, than your 
HT signal is just another input. Your only option is, when you choose that input and assuming your preamp has 0 amplification, to turn the preamp all the way up and forget about it. All control is done from your HT device.
HT pass through is a feature.

Unity gain is a state of 0 amplification/attenuation.

I cannot speak to wiring/specifics but I believe this:

A HT pass through will remove/bypass any amplification/attenuation from the signal path. Think of it this way: When you engage HT bypass, it is as if the preamplifier is completely removed from the signal path. You are sending the signal directly from your A/V processor/receiver to your two-channel amplifier.

When you disengage the HT option, you will revert to the last volume setting. Presumably, this will not be a setting that can cause damage to equipment or hearing.

If your preamplifier does not have a dedicated HT pass through function, it will depend on your preamplifier what happens next.

As far as I know, most preamplifiers are attenuators. Therefore, to achieve Unity Gain (a state of 0 amplification/attenuation), the "volume" must be turned all the way up.

Of course, this leaves open the potential for a situation where, when switching back to a different source, the volume will be at a very high level.
At 0 attenuation, the signal is, effectively, passing through.

It's only "risky" if the operator doesn't understand the concept and how it works.
Seriously?

Is this some campaign against Schiit?

Or are people just incapable of taking responsibility for their actions?

If you don't like it or know how to use it, why not return it?
What jperry said:  The words "home theatre" are not in the owner's manual for the Schiit Freya.
OP,

My points are these:

1. Schiit does NOT market this as a "home theatre bypass solution". Two lines speaking in general terms about a product class at the bottom of one page on their site does not constitute marketing. Find me one print/online advertisement where Schiit specifically recommends their preamps as a home theatre product. I'll wait.

(I suspect you only found this verbiage AFTER you decided to start this thread, when you realized that most people saw through your story).

2. The manual is most of the story. Especially when one considers your false "marketing" argument. There is no mention of home theatre in the manual. This is not designed as a home theatre device.

There is no "serious issue" for Schiit to "resolve".

3. But, since you want to hang your hat on this feeble argument, let's take a look at it.

The verbiage in question is as follows: "Home Theater Integration, $0. Okay, all you "home theater bypass" guys. All of our preamps offer true home theater bypass. Just plug in your processor's front channels to any input, select Passive mode, and turn the volume all the way up. Presto! 1:1 home theater bypass, with only a relay in the signal path."

Read that carefully. Or for the first time, I suspect.

"... and turn the volume all the way up."

What did you think was going to happen when you switched to a different input, other than the one being used for home theatre?

Are you really going to try and make up an excuse? You keep saying this is Schiit's fault because of these instructions. You chose to go here.

Are you going to say that because the words told you to turn it all the way up that you couldn't logically conclude that maybe you ought to turn it back down before switching inputs?

Are you going to argue that Schiit should put in a warning about high volume levels being dangerous?

Maybe the wording should include a reminder to turn the volume back down.

If that's the case, I don't see much hope for humankind.

Have we gotten to the point where we are totally incapable of thinking for ourselves? We can't take responsibility for anything?

Sad.

p.s.: What about those e-mails?
Show us the e-mails. Otherwise, you're just making it up.
Because they have done nothing wrong. Why are you so against this company?
It's not a HT product. It can be if the user knows what they are doing. There is a difference.
Warnings are on page 2 of the owner's manual.
If you don't know the dangers of maximum volume, you should not be using this product.
