f. Select MENU – Increment SITE #, then select YES
and press OK. This will start a fresh analysis log
for this installation’s site analysis test.
1.2. Maximize the Probability of Success
It is a good idea to identify potential interference sources before
starting the test. This will streamline the process.
1. Before any test, look at the entire house for potential
interference and treat the interference with NV-HPNF
filters. See section 1.7 The NV-HPNF HomePlug Noise
Filter. The following are good candidates to be treated
with an NV-HPNF.
a. As stated earlier in this section, electronics plugged
into high quality surge suppressors often used with
audio/video suites probably do not need filters, but
should be noted for checking with a filter if
problems are encountered later.
b. Low cost surge suppressor power strips SHOULD
have filters added.
c. Cable boxes and consumer electronics devices with
external power supplies will somtimes need filters,
if they are not already connected through high
quality surge suppressors.
d. Here is a short list of other possible plug-in
interfering items:
i. Wall power supplies
ii. Battery chargers
iii. Inexpensive clock radios and
alarm clocks
iv. Lamps with electronic dimmers,
such as touch lamps
v. Items with small, low duty-
cycle motors such as paper
shredders, inexpensive vacuum
cleaners,coffee grinders, electric mixers,
or electric can openers are common
interferers, but the interference is
usually confined to the zone(s) they are
close to. If it is important to hear music
while these infrequently used items are
running, filter them.
vi. Check the Renovia FAQ webpage at
nuvotechnologies.com for
an update on other potential
interference sources
2. Turn on possible interference sources which are
hard-wired (not connected to outlets):
a. Low voltage lighting
b. Any lighting on a dimmer
c. Check the Renovia FAQ page for other
potential interference sources
1.3. Identify Rooms for Each Zone and Outlets
The key to a successful installation with minimal invasion into the
home is carefully considering the location of each outlet to be used
for Zone Amplifiers.
1. Take into account both speaker and Control Pad (if
applicable) locations. Locating them in the same stud
bay is the easiest approach.
2. The outlet used for a Zone Amp connection does not
need to be inside the room. Outlets on the other side of
a shared wall can be used while keeping the Zone Amp
inside the target room.
3. It is possible to use some light switches as an AC source
for a Zone Amp, but it is not recommended.
a. It is not possible to determine which light
switches can be used without having an electrician
examine the wiring.
b. The Site Analysis Tool cannot directly test the
performance of a Zone Amp connected to a light
switch.
4. Alternate locations should also be identified for each
Zone Amp location. Don't forget to use the
standardized outlet-numbering scheme described in
step 1(e) on page 10.
1.4. Test the candidate outlets in each zone
1. Once the NV-RVSAT-Z Zone Test Tool is plugged into a
prospective zone outlet, it will establish
communication with the Hub Test Tool, as shown in
Figure 2. If the display continues to show “Searching
…”, this means there is no signal path between your
Hub location and the outlet under test. An outlet
yielding this result should not be used.
