I need to prewire a new conference room for a small financial company. Drop ceiling and framed walls; round conference room in the middle and auditorium seating on two walls. Equipment will be in a closet adjacent to the room. I'll just run Carlon 2" resi-guard smurf tube behind each TV into the drop ceiling and 1" front the conference table to the equipment closet; I'm allowed to channel into the floor(concrete, 1st floor commercial building).

What equipment would you guys recommend for a conference room if budget is not an issue? I am thinking:

Two Samsung 85" TV with touch overlay and one 75" E-Board. Or two projectors and one e-board if they want larger screen size. Room is 33' x 36'.

Speakers will be Paradigm in ceiling/backboxes with anthem receiver.

What equipment would you recommend for audiovideo conferencing?

I need mikes at the conference table and in the auditorium seating at the walls. Wireless mikes? Or something else?

I also need to be able to plug in laptops in a few locations; I can run any wires I need. What do you recommend for fiber HDMI? How is Metra?

Planning RTI touch panels/handhelds for control. I prefer iPads for residential but here I'll have to use dedicated for reliability. Hopefully their new stuff is better than their older remotes which were not kind to me(understatement)

Anything else I'm missing? First time I'm dealing with a conference room.

1. That's a decent-size conference room, and depending on the content to be displayed, 85" displays may be too small. We routinely install 113"+ screens in conference rooms

2. Decide how many source inputs you will provide so you can size your AV switcher. We typically install HDMI/VGA+audio inputs in the rack, in a lectern, on the wall, or on the table trough cable cubbys (Extron/Crestron). An HDMI/VGA input can take one or two inputs depending on whether the transmitter can (auto) switch between them. We typically use Crestron or Extron presentation switchers (control system plus + switcher) or a control system and a separate switcher. You can get switcher that have Cat5e extender inputs and outputs.

3. You will need a good DSP and size it for the number of inputs (wired/wireless mics, program audio, USB from a PC, line inputs from a VTC codec, etc.) and outputs (amp, VTC codec, USB to a PC, etc.) We use Biamp, ClearOne, and Extron DSPs. Crestron has one now, but we haven't used it yet.

Well you should probably start by using the proper equipment for the audio system. Resi gear is not suitable for commercial installations, even though you can get it to work. You should use a 70v amp and plenum rated in-ceiling speakers. If you'd like, you can do a proper stereo speaker setup by the main front display for video sources.

Like Joe above says, you'll need to figure out all your ins and outs of the system for audio and video. For conferencing, you'll need a dsp that all audio runs through so that you can maintain proper gain control and have a good reference for AEC.

I find that projectors leave a lot to be desired as far as punch for these rooms. I'd prefer a video-wall where you can have one large image or split the screens up to show several images which is great for collaboration. I'm sure this client does a lot of that. For others along the stadium seating, install several larger displays as convenience/spill over that show what's on main display.

Should be enough to get you going in the right direction. Since it's your first, have you considered partnering with another firm that does this day in/out? You can certainly help with the labor and learn a lot while the job goes on.

Thanks for the help guys. At this stage all I am doing is prewiring; I don't even know if I'll get the final job. They might just decide to move the existing older conference room equipment to the new location. I just need to figure out what cables to run at this point from the conference room table to the av location and I need to plan for a microphone solution for the auditorium seating. I am assuming it will be wireless; should I plan for a local antennas for the mikes or they would be fine if they are 30' away from the rack?

For the conference room laptop location I'm planning on 4x Cat6 UTP, 4x Cat6 STP, 2x Fiber HDMI, 1 VGA and 2 x 1" Carlon flex conduits. Anything else I am missing? What should I run for the microphones? Starquad?

For the displays I'll just run 3 Carlon 2" flex conduit into the drop ceiling on each wall that might be getting tvs for a total of 6 available TV locations and have the electricians run electrical for the motorized screen in two locations and two for projector locations.

How are you supposed to pre-wire without a design and/or specification?

Probably CAT6 plus audio everywhere,.. but really, that's just a wild guess. I think the only thing that could be done without a complete design is installing the conduit to make sure they have decent conveyance everywhere.

If you're going to do video conferencing, you need to think about one or more cameras. The Polycom RealPresence codecs (Group 310/500/700) are good choices for a hardware codec, especially if the client has to VTC with other Polycom endpoints. The Polycom codecs have their own cameras which can be mounted in different locations, depending on the model. These cameras have their own cables.

If the client wants to use a soft codec like Skype For Business, WebEx, etc., then you would use cameras from Vaddio, HuddleCam, etc. These cameras use Cat5e/Cat6 cable and would need to be accounted for.

Excellent question. There are many ways to design a conference room, depending on requirements, budget, etc. It might be possible to put enough pre-wire in to account for everything, but it's not nearly as efficient as designing it first.

Also, if the room will have a drop ceiling and framed walls (assuming normal commercial construction with metal studs), with the exception of AC power to the projector(s), displays(s), and screen(s), it's possible (and common) to do all the wiring after the room is built.

I actually don't have any plans, not even for the table or furniture. At this point all I am doing is prewiring; I'll have them tell me where they will want the displays and have the electricians run some extra BX into the ceiling for screens and projector. I'll run some 1" conduit, cat6 and audio from the conference table; that should cover me for anything that they want. The wall are framed and I can run whatever I want later on. What cables should I run for the microphones from the conference table? Regular microphone cable or the conference systems use something else?

For the mic audio input, a mic cable (shielded 2-conductor cable) is what you need.
As for any other cables, it depends on whether you want to have a mute switch and indicator LED at the mic. We recently installed ClockAudio CRM 202S-RF table-mounted boundary mics in an NIH conference room and they use a Cat5e cable for a touch-sensitive mute switch and a Red/Green LED mute indicator ring. On the mic end, there is an RJ45 connector and at the control system end, the Cat5e cable breaks out to connect to I/O ports.

The table will be pretty big, probably with 20-30 seats. What microphone system should I be looking at? What is the current state of the art in this area?

If the microphones are wired, do I have to run mic cables for each microphone to the av closet or there will be a local mixer at the table?

This should be fun to watch.

Do you even know if theit budget is $50,000 or $500,000+ ?

You are kidding, or you're trolling us, or you have absolutely no idea how much trouble you're in.

The UN Security Council has fifteen members. You're guessing (GUESSING!) the table will have a third more to twice as many seats. And those two numbers probably call for different equipment.

You've been told to partner up with someone who can do this, with the partnership in such a way that you learn while you do. That's your answer.
A good answer is easier with a clear question giving the make and model of everything.

I second, or is it third, to partner up with someone, or bow out due to inexperience. If this truly is a state of the art conference room with no plans, no budget, no scope of work, not even a list of equipment scribbled onto a cocktail napkin this is going to turn out painful for both sides.
