In this blog post, I will break down how to plan and set up an affordable multi-room AV system.
Plan Your System Setup
The first step is planning out how you want your system to be configured. Determine how many rooms you want to include and where you want speakers located. Sketch out a basic layout of your home and note where sources of audio like a TV, streaming device or stereo would be. Also consider if you want certain zones to play the same audio or have independent sources. Taking time to map this out upfront will save headaches later on.
Choose Your Audio Source Device(s)
You'll need an audio source to feed your different zones. Some affordable options include:
Streaming device
A device like a Chromecast Audio, Fire TV Stick or Apple TV can stream music services throughout your home for a low cost. Plug it into your receiver or integrated amp to control playback centrally.
Old laptop or desktop computer
Repurpose an existing computer by installing media server software. This allows you to organize your digital music library and access it from any room.
Bluetooth receiver
For a simple single-room solution, a Bluetooth receiver connected to speakers lets you stream directly from a phone or tablet.
Think about placement of your source equipment for best whole-home coverage. Consider running longer cables if needed.
Select Amplification and Distribution
Now you'll need a way to amplify and send that audio around your home. Some versatile yet affordable options are:
Home theater receiver
Even basic entry-level receivers have multi-zone capabilities these days. Check used options which provide good value.
Integrated amplifier
Models with mulitple analog or digital inputs let you easily switch between audio sources for different rooms.
Audio streaming amplifier
All-in-one units like the Denon HEOS amplify and distribute music over your WiFi network for multiple rooms.
Passive volume controls
For a truly budget build, add volume controls to each speaker zone and feed the uns amplified main audio through the house on speaker wire.
Distributing audio can be as simple as running audio cables, or you may want to invest in a whole-home wireless system for flexibility. Consider your specific needs and budget.
Choose Appropriate Speakers
Speakers are arguably the most important component for sound quality. Buy the best you can afford within your budget. For whole-home coverage, consider:
In-ceiling or in-wall speakers
Great for primary listening areas like living room and they hide wiring messily. Install professionally for best results.
Bookshelf speakers
Compact and affordable. Place them throughout home on shelves or stands behind furniture for fill audio.
Outdoor speakers
Add waterproof options for poolside or patio to extend your system outdoors too.
Subwoofer
For rooms with a TV or serious music listening, add a sub for full-bodied low frequencies.
When placing speakers, think about acoustic treatment and spacing to disperse audio evenly. Aim to have at least one pair of speakers per 'zone'.
Bring it All Together
Once you've selected all your system components, it's time to start installation. Here are some final tips:
Run all your speaker wiring before mounting or installation to avoid headaches later. Consider adding an extra run or two just in case.
Neatly label all your cable ends to avoid confusion later when connecting sources and amps.
Test each audio zone individually before closing up walls. Make sure levels and connections are correct.

Virtual reality (VR) technology is rapidly progressing and bringing new innovative solutions to various industries. One such industry that is being transformed with the integration of VR is the audio-visual (AV) sector for conference rooms. Traditionally, conference rooms relied on physical attendance but with advancements in VR, remote participation is now possible like never before. This blog focuses on exploring the role VR is playing in enhancing conferencing experience and how it is changing the landscape of conference room AV solutions.
What is Virtual Reality?
Before understanding how VR is impacting conference room AV, let's first understand what VR actually is. Virtual reality is a computer-simulated environment that can be similar to or completely different from the real world. It immerses the user by making them feel like they are present in that virtual world or environment. VR uses head-mounted displays or multi-projected environments, sometimes in combination with other sensory devices like gloves, that respond to the user's movements. This provides an immersive experience as the users can look around the virtual space, move around and interact with virtual objects or other avatars as if they were real. The goal of VR is to convince the brain that the virtual experiences being supplied are not different from physical reality.
Enabling Remote Participation
One of the biggest impacts of VR on conference rooms is that it enables remote participation just like physical attendance. With VR headsets, participants can join virtually from anywhere across the globe and feel like they are physically present in the conference room. This is a huge advantage as it saves traveling time and costs for the participants. They can seamlessly collaborate in real-time with others in the conference room through their avatars. Meeting organizers too can maximize participation by allowing geographically dispersed team members and stakeholders to join virtually. VR headsets provide a 360-degree virtual depiction of the conference room from the remote user's perspective so they have the sensation of truly "being there".
Immersive Virtual Meetings
Through VR, conferences and meetings are becoming highly immersive experiences. Remote participants appreciate being able to look around the conference room virtually, see who else is present physically as well as interact with them using hand gestures or controllers. This makes their experience almost identical to in-person participation and makes it easier to engage, network as well as read body language cues which is otherwise difficult on traditional video conferencing calls. Such immersive VR meetings allow building deeper connections among participants. Presenters also find VR conferencing more dynamic and engaging as their full-body motion and gestures are visible to everyone.
Collaborative Virtual Workspaces
Along with virtual meetings, VR allows setting up collaborative workspaces that multiple users can access simultaneously through their avatars. During conferences, this enables remote brainstorming on virtual whiteboards, sharing and annotating 3D designs/models together, walking through architectural plans, etc. Participants have their own VR viewpoints but can also tune into others' perspectives. Features like these expedite decision making. Virtual workspaces facilitate seamless networking among attendees by letting them mingle in between sessions. Organizers can even set up customized virtual booths for sponsors in the VR environment of the conference.
Enhanced Learning Through Virtual Labs
VR offers tremendous promise for enhanced learning when incorporated in conferences focusing on science, technology, engineering or medicine. It gives participants the ability to experience virtual labs, dissections or experiments. For e.g., a medical conference can simulate various surgical procedures or demonstrations through virtual operating theatres for attendees. Engineering conferences can let users interactively examine mechanical parts, infrastructure models or complex systems in VR. The experiential, hands-on aspect aids better comprehension and retention of knowledge for both in-person as well as remote attendees. Virtual labs are highly useful for continuing education programs and skill development sessions conducted as part of conferences.
Data Integration Capabilities
A key benefit of integrating VR into modern conference rooms is the capability to overlay useful data from various sources onto the virtual environment. For collaborative VR spaces, team members can work on integrated 3D models and data visualizations. Conference organizers get tools to incorporate presentation slides, charts, analytics, and other information streams seamlessly onto the virtual whiteboards or displays. Remote participants benefit from being able to clearly see shared content from any viewpoint through their VR headsets. Real-time updates are also possible during discussions. Data integration helps maximize knowledge dissemination and decision making productivity during VR conferences.
