What if I am active surround and center speakers to my existing stereo monitors and subwoofer speakers?
The Crown XLS1002 is a two-channel amplifier having a maximum power output of 350 Watts at 4 Ohms. This amplifier is best option for a starter home theatre system setup. or you can go with Nobsound Lepy Power Amplifier which is for 4 channel but again it depends.

It's almost categorically a no-no.

From my computer I have access to all my speakers via ASIO I just change the output options.

1, AV Amp, using the HDMI from computer to amp that goes to my screen.
2. Internal computer speakers
3. connected ASIO device, I have a few so could be x32, sapphire Liquid etc

My AV amp is atmos 7.2 since I am using window there is no Digital ATMOS software its MAC only so I can only mix in 7.2. In my DAW I create output channels for the various speakers either in mono or stereo pairs. Works fine in studio one but it has no surround mixdown feature so I have to use cubase or Pro Tools.

I have a full Atmos system, it is still fun mixing in 7.2 with the rear ceiling speakers especially Dark Side of the Moon

And this isn't an unusual confusion, sadly, despite all our best efforts. :beamup:
And the US broadcaster was right.

I have several Blu-Ray players and tuners (all Panasonics) and none of them route anything from the 5 or 7 main channels to the sub. And I have noticed that several UK and Irish recordings fail to include a bass channel and assume that the bass management system will do this for them. (Leonard Cohen Live in Dublin springs to mind.) Recordings made in France, Germany and the US merge the ordinary bass and the LFE for domestic streaming, broadcasting and disks.

Yes, professional bass management does route to the sub - but domestic players usually do not.

Apart from all that, if the customer wants a mix done in a certain way, the last thing you do is argue with them.

In a well-equipped cinema, yes. But as stated - most home systems do not.

None that I have come across, though some soundbars may do this.

To the OP - you need five or seven identical speakers to get a decent surround mix. A set of small Genelecs and a Genelec sub is what I recommend. Failing that, a Sennheiser 'Ambeo' is often used to check 3D mixes, though I have no personal experience of using one, but a friend whose opinion I do respect (he's recorded and mixed everybody from Pavarotti to The Stones) told me that it is better than separate speakers. I suppose I'll have to find out one day!

No. They categorically weren't.

They aren't normally supposed to. Bass management is normally a function of the controller/amplifier, not the player.

It is supposed to! If you buy something under-specified you can't blame the content creators for it!

Domestic Surround amps do!

You are confusing channels and speakers. The CHANNELS are all flat down to 5Hz, even in domestic players. If the domestic user's speakers aren't full range (and few will be) they need a system that implements bass management. That facility might be in their surround controller / amplifier system, or it might be in their subwoofer. But it will be there somewhere.

Your "fact checking" response is very helpful Hugh.
For a while I wondered if nearly all I thought I knew about bass management was a myth! Thanks :thumbup:

One of my various gigs is to check DVDs and BR disks for the European market and all films have the LFE and the Bass routed to the subchannel. That is part of the tech sheet from every studio/distributor.

If you are putting music broadcasts through a distribution system that requires things to happen a certain way, that is what you have to do. What the BBC does in its own little world is totally irrelevant to the US studio system and US broadcasters.

As 'Later' is shown by MTV, the giant Viacom company will be the ones having to deal with BBC petty arrogance. As we also master and edit stuff for the BBC, I for one can verify that their tech departments live in their own private world of silly games. Considering that they are the worst payers by a considerable margin, their games are hardly justified. (Fortunately, I am not the person who has to deal with them, but I hear the cries of frustration!)

For those casual readers here who want to submit material for Netflix or any other US distributor or broadcaster, stick religiously to their tech specs. If you do not, the material will be rejected.
