Introduction

Congratulations on your purchase of a VTL Signature Preamplifier:
design to challenge all others."
T
his hand crafted component is designed to deliver superb performance for your
listening pleasure for many years to come. In order to get the most benefit from your
purchase, we recommend that you take sufficient time to get familiar with the features
of this product. Please take a moment to read through this owner's manual, as it
contains all of the installation procedures needed to connect your new TL 6.5 to the rest of
your audio system, as well as the many functions that the TL 6.5 can perform. After you have
finished reading this manual it should be kept it in a safe place for future reference.
As a significant and important product for VTL, the TL6.5 Signature Line Preamplifier is a fully
differential circuit, and is designed to be the ideal matching front end for the VTL Reference
power amplifiers, as well as the Signature MB-185 and MB-450 monoblocks, but due to the
design of the TL 6.5 it will drive any power amplifier with the same result.
As VTL's top preamplifier in the Signature family, with an integral power supply control section
and multiple fully regulated power supplies to preserve tonal and spatial accuracy, the TL 6.5
incorporates all of the design specification and features of the VTL Signature series, and
sonically leads the listener through the intricate tapestry of musical layers, with superior control
and tonal balance. The TL 6.5 Preamplifier truly represents a fresh breakthrough in furthering
the refinement of the VTL sound, and the ability of the new TL 6.5 to articulate and present
the listener with a broad, cohesive picture of the total musical soundscape in a dynamic, nimble,
full range sound gives it the distinction it bears as our Signature Preamplifier. As you will find,
this preamplifier commands your attention to music itself and unravels before your eyes and
ears the most intricate emotional layers that is the essence of music.
Preamplifiers offer the user many benefits that direct connections cannot. A line stage with gain
(and therefore dynamic headroom) always yields superior sound in dynamic musical passages.
Ease of installation is another primary benefit with preamplifiers. Yet another benefit from a
high current output buffer is to lower the output impedance to drive the next stage (usually a
power amplifier, with unknown input impedance) and/or the interconnecting cable, with
potentially high capacitance in long lengths.
The VTL TL 6.5 Signature Line preamplifier is both a fully active line level preamplifier and a
complete source control center in one package, and it offers complete predictability of
performance with little or no change of response in a wide range of systems and environments.
This preamplifier is a true Signature Component, insofar as it contains some of the most
advanced thinking in preamplifier design today.
The major design goal for the TL 6.5 was to sonically outperform any existing single-chassis
preamplifier design, using measurements to back up empirical findings, and the technical
challenge of designing a fully differential circuit with sufficient common mode rejection ratio
