Connecting the TL5.5 to a Home Theater System
Your VTL TL5.5 preamplifier is designed to work in conjunction with both
conventional two-channel and 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 surround processor front left and right main
outputs to any of the preamplifier’s inputs. This will allow the surround processor
to drive the front left and right speakers when the unity input is engaged.
Under this configuration, when you are listening to your two-channel audio system
from sources connected to the line inputs of the TL5.5 then select the relevant
input. The source components and the TL5.5 are now driving the front speakers,
giving you the full volume control and source selection.
When you want to use your system for home theater, select the input that has
been set for unity (see the appropriate section for instructions on how to set an
input to unity gain).
Under this configuration the TL5.5 receives the external surround processor's
signal for the front left and right channels directly from the external surround
processor, and passes it directly to the power amplifiers at the same level that the
Processor is putting out. This means that in this mode the volume control is fixed,
and the signal is passed to the front left and right amplifiers at unity gain through
the gain stage. This gives the external surround processor the volume control of
these channels while controlling the center, rear and subwoofer channels at the
same time.
Caution: Before unmuting the preamplifier after selecting the unity position,
ensure that you adjust the volume of the surround processor to a low level to
protect your system from high signals that might result.
Caution: If you do not have a surround processor connected to the TL5.5’s
unity input, you may get a slight buzzing sound when you select the unity
position, which comes from the open input of the power amplifier. This slight
buzz will not damage anything in your system, but should be corrected by
terminating the input properly.
Using the TL-5.5 to trigger other devices
The TL-5.5 offers two trigger outputs that, if programmed, will supply a low current
12V hold while the unit is powered on. (See separate section on programming one or
both of the trigger outputs.)
The connector used to connect to the trigger output of the TL-5.5 is a Phoenix
connector, p/n 1792757, and fits into the mating header (Phoenix p/n 1872460) on
the rear apron of the TL-5.5. The connector only plugs in one way, so it is polarized.
