I am designing several churches.

Can you give me a generic spec for the following wiring? [I don't mean a specific brand, just a designation, like "CAT-5" and "RJ-45" for network wiring, etc]


1.. From Microphone jacks at pulpit to sound board
1.. cable:
2.. connector:
3.. box recessed into pulpit [brand name/# ?]
2.. From Sound Board to amplifier
1.. cable
2.. connector
3.. From Amplifier to Speaker Jack
1.. cable
2.. connector
4.. From Video Projector to PC at sound board
1.. cable
2.. connector
Thanks!!!

From Microphone jacks at pulpit to sound board
cable: 2-conductor shielded audio cable
connector: XLR or TRS as appropriate

box recessed into pulpit [brand name/# ?]
From Sound Board to amplifier
cable: 2-conductor shielded audio cable
connector: XLR or TRS as appropriate

From Amplifier to Speaker Jack
cable: 12-16 gauge low voltage
connector: 1/4" mono phone or SpeakOn as appropriate

From Video Projector to PC at sound board
cable
connector

Depends on the input video projector, but if it has a 15 pin RGB input, then
one uses RGB extension cables such as are used with KVM switches.

Here are my suggestions, realizing that I work for Belden, a cable
manufacturer. (The non-cable suggestions are mine personally and not the
opinion of Belden corporately.)


1.. From Microphone jacks at pulpit to sound board
1.. cable:
2.. connector:
I would use Belden 1800F. This is ultralow capacitance (13pF/ft.) for maximum
performance but is very flexible and comes in a variety of colors. (I would
guess you will want black so it is not obvious.)

My peronal favorite connectors are the Neutrik NC3FX-B and MX-B but any XLR
connector (Switchcraft A3F/A3M, ITT Canon etc.) will work just fine.
3.. box recessed into pulpit [brand name/# ?]
I assume you mean the mic cable goes into a box which then transitions to an
install-grade cable from there to the mixer. I would use Belden 1800B which
has the same performance as the 1800F but much lower price and is install-only.
If you have multiple microphone, we also make this in multipair snake up to 32
pair.
2.. From Sound Board to amplifier
1.. cable
2.. connector=20
Question: is the output of the mixer balanced (XLR) or unbalanced (RCA/mono
phone plug)?

BALANCED: 1800B and XLRs as above.
UNBALANCED: Belden 1505A and Canare RCA connectors. (Note that I am
recommending a competitors!!! connectors, so they must be pretty good.) If it's
phone plug, I would have to think about whose plug (check Neutrik or Canare).
3.. From Amplifier to Speaker Jack
I assume you are using the direct out (i.e. 8 ohms etc.) and this is not a
70-volt distributed system. If you have long speaker runs, more than 100 ft.,
I would suggest an amplifier with 70-v output and transformer-fed speakers. If
you don't know what this means, email me and I will explain further.
1.. cable
2.. connector
8 ohm output: Belden 8477 (12 AWG). If you want REALLY low loss, we have the
only UL-recognized 10 AWG speaker cable (Belden 5T00UP), yes a weird part
number for us. Check this (and all these cables) out at www.belden.com

This assumes standard amp and speaker terminals. If you have Neutrik Speakon
outputs at the amp and Speakons at the speaker, we do make that cable too:
Belden 1810A (4 X 14 AWG)
Belden 1811A (8X14 AWG)
4.. From Video Projector to PC at sound board
1.. cable
2.. connector
A previous post said it. Is this VGA, like a laptop? High-density 15-pin
connector? Or RGB? (probably not). What distance are you going? You can get
premade VGA cables for cheap. If they are not long enough or the picture looks
like crap, and you want to make your own cables...let's talk. (Making VGA
cables is NOT FUN.)
Thanks!!!
