PS3 & Pio AX2AS sound support


Prominent Member
Hi, can i tick the boxes in audio setup on the ps3, for instance 5.1 192Khz. Nearly all are ticked except the highest ones? I tried and it said i could damamge speakers so i thought it would be best not to change. Does my amp or speakers have to support these frequencies? or both?

Not really if they know it off the top of their head.Or have the same settings

I couldnt find anything in the manual, only

D/A Converter 192 kHZ/24-Bit

A/D Converter 96 kHz/24-Bit (2-channel)

but i am unsure what it means? ***Why would i convert digital to analogue***? I am not very clued up on amps/audio yet. Sorry!!


***Most modern audio signals are stored in digital form (for example MP3s and CDs) and in order to be heard through speakers they must be converted into an analog signal. DACs are therefore found in CD players, digital music players, and PC sound cards.

Specialist stand-alone DACs can also be found in high-end hi-fi systems. These normally take the digital output of a CD player (or dedicated transport) and convert the signal into a line-level output that can then be fed into a pre-amplifier stage. Some of these can also be made to interface with computers using a USB interface.***

So from this info, my amp does support it and to be heard needs to be converted to analogue. What benefits will i get from this then? if you dont mind answering that question.


I can't answer specific details for your setup, but (with apologies if this is all obvious):

The function of your Amp is to power your speakers, which require relatively high power (watts) and high current (amps) analogue (continuously varying) electrical signals. This section is called the power amplifier (makes the power bigger - see?) and there is one power amplifier per speaker. To use these with multiple sources, it includes selection from multiple inputs and conversion of many input formats to the seperate analogue signals required. This part is called the pre-amp. Being an AV amp, it also selects and converts video formats for delivery to your screen, but there's no power amplifier for them.

Digital signals don't degrade; analogue do, so keep everything digital right up to the amp if you can. Even more so for amps that perform speaker and room equalisation in the pre-amp. They will convert everything to digital anyway.

You are extremely unlikely to damage your amp or speakers by selecting higher frequencies/resolutions. Most likely it will simply ignore the input if it can't accept it. The most likely way to damage your speakers is to turn the amp up to max with no input because you can't hear anything; then switch the input to something which the amp can process.


Sorry, I should have said what difference will i notice between 192Khz and 96Khz for example.
None. I think it's extremely unlikely that anyone can hear the difference in a double blind trial, regardless of the equipment being used. Nevertheless, there is reason for the digital processing that is performed by your AV amp to take place at higher precision than you can hear. CD's are 44kHz; around 20kHz is the highest frequency any human can actually hear. Read this on Wikipedia if you want to understand the significance of the sampling frequency.
