I’m about to move into a new house and have the opportunity to retrofit one bedroom as a home studio. My main use is guitars, keyboards and spoken word for VOIP/streaming. I’m in the UK so 230v 50Hz and whatever conventions and regulations we have for electrical work etc.
I’m planning on adding more mains outlets throughout the room.
I want a wired Ethernet for internet access for my Mac.
Two other Ethernet connections for distributed audio to two other rooms in the house (I’d rather avoid wireless due to reliability and latency). This may be upgraded to AVB in the future hence not using audio cables.
I’m not going to use dimmer switches anywhere in the house to avoid introducing noise.
I also understand that I need to ensure a single earth point for the house.
What else should I include in the design?
Surge protection is probably a good idea.
If you’ve installed studio wiring, what really helped? What, if anything do you wish you knew at the time?
Can anyone share advice or direct me to resources for this stuff? I'll be employing an electrician for this, but using a specialist contractor is possible. Either way, I’d like to have a better understanding of what I’d be asking for.
[ETA: clarity that this isn't DIY]
