General Installation FAQ |
| Question |
Answer |
|
| What
type of wire
do you recommend for analog and digital audio? |
Any modern installation will benefit
by using digital audio wire
exclusively for all analog and digital connections. Cable designed for
digital audio has low capacitance, tight twist tolerances, and provides
superior performance compared to analog cable. |
|
| What
gauge of wire
should I use with my D-sub 25 connectors? |
The factory supplied crimp style AMP
DB-25 mating connectors (Amp part
number 1-745496-8)
are designed for 26 to 22 AWG wire. |
|
| What
kind of punch
blocks should I use for my digital audio
installation? |
We recommend Krone 50 pair
termination blocks – model
6652-1-880-10.
Be
sure to wire the blocks in a pattern of Pair 1 H-L-SH, Pair 2 SH-H-L,
Pair 3
H-L-SH, etc., to take advantage of the built in patch and test
point cables manufactured by Krone. |
|
| How
do I wire an
unbalanced analog output to a balanced analog input? |
Wire the unbalanced Hi to the
balanced Hi, unbalanced Shield to the
balanced side Lo and Shield. |
|
| How
do I connect an
unbalanced DIGITAL (SPDIF) CD output to a balanced
AES input? |
We suggest using a "balun" or format
converter if possible, but if
not available you can try connecting the CD (+) to AES in HI (+),
connect CD (-) to AES in LO(-). Leave the AES input’s Shield
connected at the console/card end only. This works because all of our
AES inputs are transformer coupled. The impedance is not correctly
matched, but this method will work in a pinch. The AES receiver will
ignore the copy protect (SCMS) bit. |
|
| How
do I connect a
balanced AES digital console output to an unbalanced
(SPDIF) input? |
You must use an external AES to SPDIF
converter. |
|
| Do
I need to use a
telephone hybrid with the phone module? |
Yes. Phone modules are
designed to interface via balanced analog
line level connections to an external telephone hybrid. They
are
NOT
intended to interface directly with the phone line. Doing so
can
result
in damage to the console. |
|
| Where
can I find
phone module application information? |
Please see our white paper Making
The Connection (pdf). |
|
| How
do I use the
channel ON tallies from my three mic channels to
make my ON Air light come on whenever any of three mics are on? |
To do it this way with some consoles
you need to add diodes in what
is commonly called a wired-OR configuration. The orientation of the
diodes will depend on the polarity of components and/or voltages in the
external circuitry. But this is generally not necessary. On most of our
consoles you can set the CR mute function for the desired mic channels
and then wire your ON AIR light to the console’s ON AIR TALLY
output,
following the console-specific instructions as outlined in the
console’s manual. |
|
| Do
I need to use an
external DC power supply when wiring logic
connections? |
In most cases the answer is no.
On many Audioarts consoles the logic circuits are opto-isolated
for maximum protection. But in most cases +5VDC and digital ground are
provided on the logic connector. Refer to the manual for your
specific console model for details.. |
|
| What
size UPS
should I buy for my console? |
See the suggested UPS rating for your
Audioarts Engineering product as shown in the table
below. Note that these
ratings are based on the maximum configuration for the product. Your
product may be short loaded or draw less power than shown in the table.
