unpleasantly and/or damage your hearing.
Caution: Do not set the headphone selector switch to the headphone
mode if there is no headphone connected to the IT-85 as this may cause
the internal headphone load resistors to heat up unnecessarily.
There is a safety feature in the IT-85 that will automatically mute the IT-85 before
permanent damage is caused in case this condition accidentally happens, which
will turn the pre outs (i.e. subwoofer or lower amplifier, if connected) on and off
intermittently. If you hear this condition then lower the volume and check to see
that the headphone selector switch is set to the correct position.
Connecting the IT-85 to a Home Theater System
Your VTL IT-85 integrated amplifier is designed to work in conjunction both
with conventional two-channel and with home theater systems. If you have both
systems set up so that your front speakers are used for your audio as well as home
theater systems, then connect the external processor front left and right outputs to
the IT-85 Processor/Amp In input, so that it will be able up to drive the front left
and right speakers.
Under this configuration, when you are listening to your two-channel audio
system from sources connected to the line inputs of the IT-85 set the Processor
switch on the IT-85 front panel to the default operating position (down). The
system and the IT-85 are now driving the front speakers, giving you the full
volume control and source selection.
When you wish to use your system for home theater, set the processor switch to
the
Processor position (up). Under this configuration the IT-85 amplifier section
receives the external surround processor's signal for the front left and right
channels directly from the external surround processor. This gives the external
surround processor the volume control of these channels, at the same time as it is
controlling the center, rear and subwoofer channels.
Note that when using any type of bi-amplified system, either with a sub-woofer or
with another amplifier controlling another part of the front left and right speakers,
this function will be muted when switching to the Processor position. The preamp
out from the IT-85 is always controlled by the volume control in the preamplifier
section of the IT-85. Note that in home theater use the bass signal is usually
dedicated to the subwoofer output from the external processor, which may render
a subwoofer less useful when connected to the front left and right outputs. In this
type of installation a second subwoofer is recommended.
