multiple Speaker Pair Installation and Connections
Connecting the Vital 710 to multiple speaker pair is pretty similar to connecting a single pair, just with more con-
nections. The big difference is the use of impedance matching volume controls and use/connection of the 1
IN, 4 OUT Speaker Terminal.
Note:
The 1 IN, 4 OUT Speaker Terminal shown in the Example System in
Figure 8
is a generic representation of
this type of device. There are many options available for this type of device, the only requirement is that it be a
passive, (non-impedance matching) component, rated for 100 Watts, min.
1.
Set the Slide Switches on the volume controls per the Impedance Matching Chart. (Chart 1)
Note:
The impedance setting should be the same on all volume controls.
2.
Using 16AWG (min) 2-conductor stranded speaker wire, strip approximately 1/2 to 3/4 of an inch off the
ends and twist the strands together so there are no loose ends that can cause shorts.
3.
Loosen the Speaker A Terminals as shown in
Figure 7
so there is enough room between the post and the col-
lar to feed the striped wire through without damaging the strands.
4.
Tighten the post to secure the wire.
5.
Repeat for Speaker A Left and Right, + and -. Confirm connection and polarity.
6.
Connect the speaker wires to the appropriate left and right, + and - Speaker IN Terminals on the 1 IN, 6 OUT
Speaker Terminal, or equivalent, as shown in
Figure 8
. Confirm connection and polarity.
7.
Connect the speaker wire for Room 1 to the Speaker 1 left and right, + and - OUTPUT on the 1 IN, 6 OUT
Speaker Terminal. Connect the other end to the left and right + and - INPUT on the Volume Control in Room
1. Confirm connection and polarity.
8.
Connect the speaker wire for the Room 1 Speakers to the Volume Control left and right + and - OUTPUT.
Connect the other end to the Room 1 left and right + and - Speaker Terminals. Confirm connection and
polarity.
9.
Install the volume control into the J-box per volume control instructions.
Note:
Never install a volume control in a J-box with high voltage devices. This can introduce noise to the
audio system and is a violation of Building and Electrical Code in most places.
10.
Repeat
Steps 8-9
for the Volume Control/Speaker sets for all other rooms.
11.
To test, set the Vital 710 to a moderate volume and play a source, (CD, Tuner, etc). Confirm audio output
from both speakers in each room. Turn the VSi60 Volume Control Knob to confirm volume UP/DOWN. Adjust
the Vital 710 Balance control full right to confirm only the right speakers are on. Adjust Vital 710 Balance
control full left to confirm only the left speakers are on. Correct connections as necessary.
12.
For regular use, set the room volume controls to full ON. Adjust the Vital 710 to a good listening level. Leave
the Vital 710 volume control in that setting and adjust volume with the individual room volume controls.
