CONNECTIONS
Subwoofer
Figure 6
shows connections for adding a powered subwoofer with a 12V Control Input to Speaker A using the
Sub A Out connections. This configuration will have the subwoofer turn ON when Speaker A is turned ON and
turn OFF when Speaker A is turned OFF. The sub will also mute when Speaker A is mute. To configure Sub A as
shown in

Note:
There are several different ways to connect a subwoofer to an audio receiver. One is to have the re-
ceiver’s speaker level output connected to speaker level inputs on the sub. The sub then acts as a crossover,
separating the high and low frequencies with the low frequencies going to the sub and the mid and high fre-
quencies going to the connected left and right speakers. Some subs are passive (as just described), some are
amplified, some have left and right line level inputs, some are mono for a mono signal from the receiver. The
following describes a typical application for a powered sub that accepts a mono line level audio signal from
the Vital 710, with the left and right speakers connected to the Vital 710 Speaker A terminals. Please refer to the
subwoofer manufacturer’s instructions for connection and operating options for varying subwoofer applica-
tions.
Sub A Out Connections
Audio
1.
Using a mono RCA-RCA cable, connect the Sub A MONO Jack on the Vital 710 to the Audio Line IN on
the subwoofer. Some subs will have adjustable crossover points to match the low frequency cut-off of
the left and right speakers. Refer to the sub manufacturer’s instructions for additional information.
Trigger Out
1.
Using a mono Mini-Mini Cable, connect the Sub A Trigger Out Jack on the Vital 710 to the Control IN on
the subwoofer.
Note:
Some subs may have different types of connectors for the Control IN. Be sure to maintain proper
polarity when making this connection. Refer to the sub manufacturers instructions for additional informa-
tion.
Trigger Out Polarity: TIP=+15VDC, SLEEVE=GND
Link S/W 1
1.
Set the Link S/W 1 Switch to the ON position. This will have the Sub A Mono Out and Trigger Out turn ON/
OFF with Speaker A status. (When Speaker A is ON, Sub A Mono Out will output full-band line level audio
and Sub A Trigger Out will output a 15VDC Control Voltage. When Speaker A is OFF, both will turn OFF.
Speaker B
A second pair of 8Ω speakers can be connected directly to the Vital 710 using the Speaker B Terminals. This al-
lows having a second pair of speakers that can be turned ON and OFF from the Vital 710 Front Panel or Remote
Control. This application is convenient for adding a pair of patio speakers that would not be left on all the time
or a pair of speakers for another room.
Note:
Do not connect more than one pair of 4Ω speakers directly to the Vital 710. Do not connect more than
one pair of 8Ω speakers directly to the Speaker A and B Terminals at the same time. This will cause the Vital 710
to shut down and can damage the unit. This type of damage is not covered by the Warranty.
To connect multiple speaker pair to the Vital 710, see Section: multiple Pair Speaker Hookup on Page 18.
Speaker B Connections
1.
Follow all instructions for Speaker A, but this time use the Speaker B Terminals for the Left and Right Speakers
and Sub B Out for the subwoofer connections.
