Connecting A Second Pair Of Amplifiers - VTL TL6.5 Owner's Manual

the Record Out connectors on the preamplifier, in addition to connecting the Tape
connectors on the preamplifier to the Line Out connectors on your tape deck(s). For later
identification and monitoring of the taped source, it is strongly advised to connect the
primary tape deck to Tape 1 (in and out), and any other tape deck to Tape 2 (in and out).
Connect the Surround Sound Processor to the preamplifier . To take advantage of
the processor unity gain loop capability, connect the Front Left and Right outputs of
your home theater preamplifier processor to the left and right channels of any input on
the preamplifier, and set that input for Unity Gain by holding the Proc/Mon button
and pressing the button for that input simultaneously. Please refer to the programming
instructions in the Programming section of this manual for more details on how to set
Unity Gain.
Connect the power amplifier to the output of the preamplifier Before making any
.
connection to the power amplifier make sure that the power amplifier is completely
powered down. Any connection to a power amplifier that is powered up can result in
damage to the power amplifier and to rest of the system, and/or a loud hum from the
loudspeakers.
The interconnect cable between the amplifier and the preamplifier links the left and right
input channels of the power amplifier to the left and right outputs of the preamplifier.
The ultra low output impedance of the preamplifier is easily capable of supporting long
interconnects up to 35 feet or longer, and can also easily drive any amplifier (and sub
woofer) or cable load.
There are two sets of RCA output connectors and one set of balanced output connectors
available from the preamplifier, and all are operational at the same time. You can connect
your amplifier(s) to the preamplifier using either balanced cables or RCA cables.

Connecting a second pair of amplifiers

If you wish to use two pairs of amplifiers to drive your loudspeakers in a bi-amplified
mode you can connect the amplifiers to each of the two outputs of the preamplifier.
One pair will go to Output A and the other to Output B on the back panel of the
preamplifier.
Consult your speaker and amplifier manuals for additional installation instructions on
this mode of usage. Your dealer should also be able to give you guidance with this
procedure.
The second pair of outputs can also be used to drive a subwoofer in the system, and if you
have a second pair of amplifiers for another system, they can theoretically be connected to
the second set of outputs of the preamplifier.
Although the preamplifier can easily drive extremely low impedances, when connecting
more than one pair of amplifiers in parallel it is advised that you are aware of the different
input impedances, sensitivities and resultant input impedance. If you have any questions
