The maximum number of speakers that can be connected to the Vital 710 using impedance matching volume
controls is four pair. All four pair should be connected to the Speaker A Terminal as shown in Figure 8.
Setting Impedance
1.
The Vital 710 is capable of handling a 4Ω load. For 4Ω amp configuration using SpeakerCraft VSi60 Impedance Matching
Volume Controls, use Chart 1. If using another impedance matching device follow the manufacturer’s instructions for that
device.
2.
Add up the number of 8Ω speakers that will be connected to one channel (left or right) of the amplifier or receiver.
Find that number under “Number of 8Ω Speakers” on Chart 1.
3.
Add up the number of 4Ω speakers that will be connected to one channel (left or right) of the amplifier or receiver.
Find that number under “Number of 4Ω Speakers” on Chart 1.
4.
On the chart, follow the column under the “Number of 8Ω Speakers” and the row next to the “Number of 4Ω Speakers”
until they intersect. Set the slide switch to the letter in that box.
5.
The gray area indicates a setting that is slightly below the amplifier or receiver’s minimum impedance, but will most
likely work.

4Ω Amp Configuration
VSi60 Example 1:
The Example System in
Figure 8
has four pair of SpeakerCraft AIM5 Three Ceiling Speakers connected to six SpeakerCraft
VSi60 Impedance Matching Volume Controls. The AIM5 Three are all 8Ω speakers.
1.
To determine VSi60 Slide Switch setting, use
Chart 1.
2.
There are four pair of 8Ω speakers. Find “4”
under the 8Ω column on the chart.
3.
There are no 4Ω speakers. Find “0” next to the
4Ω row on the chart.
4.
The column and row intersect at “A”.
5.
Set the Slide Switch to “A”.
VSi60 Example 2:
Example System 2 has one pair of 8Ω speakers
and three pair of 4Ω speakers.
1.
To determine VSi60 Slide Switch setting, use
Chart 1.
2.
There is one 8Ω speaker. Find “1” under the 8Ω
column on the chart.
3.
There are three 4Ω speakers. Find “3” next to
the 4Ω row on the chart.
4.
The column and row intersect at “B”.
5.
Set the Slide Switch to “B”.
