New to the audio industry

[Aaron Kwekel]

Hello Everyone,

I currently just bought a new receiver from Denon. It’s the Denon AVR-4100W, they’re third best model on the market. I was actually wondering if DTS-X will be available for my receiver as a firmware update? This receiver is Dolby Atmos and Auro 3D certified.

One more quick question.
I currently use my PS4 as my Blu Ray player for my HT. I just bought Def Tech speakers:
2 x BP8060ST floor speakers
1 x CS8060 Center speaker
2 x BP8080 rear speakers

I was going through my audio out input option on the ps4 and noticed there were three options to pick from:
Linear PCM
Bitstream (Dolby)
Bitstream (DTS)

Personally, i felt like DTS provided a deeper bass and louder than dolby. Then i tried comparing PCM to DTS and i still felt like DTS was louder and more powerfull.

Any recommendations or options on the three audio options?

Are you using the optical output or the HDMI for audio?

I am using HDMI from Audiquest "Chocolate".

I am also using Rocket 44's from audioquest for my center channel and both floor speakers.

Odd the only audio output options are dts/dolby/pcm

Are you watching Blu-ray movies?

playing video games and sometimes movies. i was just playing around last night on my PS4 settings and it gave me these three options:
Linear PCM
Bitstream (Dolby)
Bitstream (DTS)
I personally thought DTS sounded louder and also provided a deeper bass than the other two. But from what i don't understand is why does the DTS sound better than PCM, even though PCM is not compressed audio.

With blu-rays specifically DTS-HD MA and Dolby TrueHD are both lossy codecs that have compression algorithms that compromise very little if any dynamics and fidelity. Now as to the difference, that depends on how the master was done. Technically all of them should have similar potential, including multichannel PCM. Another thing to consider, most Blu-rays will have one HD audio codec available, the rest will be legacy or 2 channel. As a requirement all blu-rays have to have Dolby Digital 5.1 if the film had it. This is standard legacy surround codec that was available on DVD as well. In addition to that it may have Dolby TrueHD, Dolby Digital Plus, multichannel PCM, DTS-HD or DTS-HD MA (master audio). Usually (I assume almost never except for music Blu-rays) the Blu-ray will only have ONE of the HD audio codecs or multichannel PCM as it's highest quality audio track.

If the PS4 is anything like the PS3 it can decode HD codecs internally and convert them to multichannel PCM for output over HDMI if you set it up like that. This is what all HD codecs get turned into before being converted from digital to analog. This was relevant when Blu-ray first became available and receivers could decode multichannel PCM but not HD codecs. Unless you have a receiver incapable of decoding HD audio codecs there's virtually no reason to set your PS4 up in this way.

Wow! lot's of useful information here, i appreciate it a a lot thank you. Now every time i put a video game in, it automatically switches over to Multi Channel PCM, unless i manually switch it over to Bitstream DTS or Bitstream Dolby. Now, when i switched it over manually, i did notice DTS seemed to be louder and provided a deeper bass than PCM and Bitstream Dolby.

What audio setup would you tend to favor, if you were playing a video game and watching a movie?

Not sure, it's been a while. I've become more of a 2 channel enthusiast as of late due to space and budgetary reasons. I would go with what sounds best to you. What I think would sound best doesn't really matter because it'll be you that is listening to it after all.
