Dear Customer,
Thank you for chosing a DI LOG preamplifier. This product is manufactured with
care under strict quality control and is a perfect example of state-of-the-art precision
technology. Even if you are familiar with hi-fi equipment, please take a moment to
study these instructions carefully and follow the instructions contained therein. Keep
this manual for future reference, it is intended as a tool to help you make the best use
of your new preamplifier.
Enjoy your new preamplifier!
Best wishes from your TRIGON - team.
The DI LOG is a FULY modular pre-amplifier. This principle allows us to continually
stay at the forefront of new technology, without having to replace the entire unit. In
addition this offers you the opportunity to make your preamplifier fit your specific
requests. There are two basic types of modules: input modules and output modules.
FOR basic operation you need at least one input and one output module. s its name
suggests, input modules are linked to the source devices. These modules select and
process the source signals before they are forwarded to the output module(s).
s an example, a phono input module has the task to amplify the very small signal
coming from the turntable and at the same time re-equalize it according to the RI
specification. Only then, the signal has the required level and frequency response to
be forwarded to the next stage, i.e. the output module to be subsequently sent to the
power amplifier to drive your loudspeakers. In short, the various input modules
normalize input signals to have a similar and usablel structure so that they can be
processed further. Output modules in turn prepare the signal to be sent to the power
amplifier(s) be further amplified to drive the speakers, or depending on the type of
output module, to a recording device. In addition, depending on the type of output
module, this is where the playback volume is controlled. The currently available
selection of modules includes: Phono, single-ended and balanced analog line input
and a digital module with optical and co-axial S/PDIF and USB inputs. Output
modules include a balanced and a single-ended module which to sets of configurable
line outputs.
The control logic and power supply for individual modules is provided by the base
unit. The base unit is the heart and the control center of DI LOG. microprocessor
manages and controls all modules and the system automatically detects each
module.
large portion of the R&D has gone into this audio control center. Today's audio
devices usually include a small computer for ease of use. Remote control is a
standard feature and a clearly legible display makes it possible to explore all the
possibilities of the unit. Without a micro-computer all this would be impossible.
From time to time it may be necessary to update the base unit's software. For this
purpose, a USB socket (19) is located on the back of the unit. This software is
provided free of charge and available for download on our website (more on that
later). Software updates will be necessary whenever a newly developed module, that
did not exist at the time of purchase of your DI LOG is to be used. The currently
loaded software version is displayed in the info menu of DI LOG. On our website you
can find the latest software version, and determine whether an update is needed.
The DI LOG's chassis of is mostly made of solid aluminum. To minimize
microphonics, a mix of materials such as steel, aluminum and wood (MDF) is used
in certain areas. The top cover, for example, consists of a sandwich of steel and
aluminum and is acoustically "dead" in the critical frequency range. The feet use a
diaphragm spring principleand decouple the DI LOG effectively from the surface on
which it rests.
The outboard main PSU contains separate supplies for audio electronics and control
electronics. In addition to this, another analog power supply used exclusively for the
audio circuitry is connected downstream in the base unit to avoid any potential
contamination of audio signals.
The system remote control operates the main functions and
features of the peamplifier.
*!,
--. assumes no liability for any damage caused by
improper handling, or failure to follow safety instructions.
mplifiers must not be installed in close proximity to heat sources such as radiators,
stoves, high power light sources, open flames, etc... and should not be exposed to
severe shocks or vibrations.
Do not connect any electronic device to C mains immediately after transport from
the cold into a warm environment. Condensation may occur and cause damage to
the device. Please wait until the unit has reached room temperature.
The amplifier should not be exposed to direct sunlight.
Make sure to install the unit with enough space for proper ventilation.
Never operate the equipment without the protective housing cover. Before opening
the unit remove the C plug from the socket.
Never attempt to bypass the fuse. Please replace a blown fuse only with a fuse of the
same type and value.
No user serviceable parts inside. ll maintenance or repair must be performed by
authorized and specially trained personnel only. Tampering and damage caused by
improper use or unauthorized intervention will void warranty.
Please turn amplifier off before connecting cables and/or other components.
The mains voltage must be between 100V and 240V C.
Use only attachments and accessories specified by the manufacturer and intended
for this purpose.
To clean the cabinet, use only a damp cloth if possible. Do not use corrosive or
abrasive cleaning fluids. Unplug the unit bvefore cleaning. Be careful not to
accidentally damage or loosen any wiring when cleaning. Check all connections for
proper fit before re-connecting the DI LOG to the grid.
W RNING! lways make sure that no liquids enter the interior of the device!

fter unpacking, first check the equipment for shipping damage. If you notice any
damage, please immediately contact your dealer. Then check the contents of two
boxes to be complete.
You should see, besides the DI LOG:
− one network cable TRIGON VOLT -
− one DI LOG instruction manual -
− one warranty registration form -
− one module remval tool -
− one DI LOG main PSU (in separate box)
The preamplifier should be installed level and in a dry location. lways ensure good
ventilation. Please be aware that strong magnetic fields, such as caused by halogen
or fluorescent light transformers can cause hum – it is recommended to keep a
minimum distance of 1m (3'). void direct sunlight and proximity to heat sources.

Once the devices are acclimatized, we recommend that you first get acquainted with
your new DI LOG preamplifier. The first step will be to connect the outboard power
supply's captive low-voltage cable (5) to the DC input jack (20) on the back of the
DI LOG's main chassis. Then plug the included TRIGON VOLT power cord to the
power imput socket (6) on the power supply and the C plug to the mains. Now turn
on the power supply with the switch (8) on the back of the PSU.

The DI LOG is now in standby mode, and the center LED (2) on the front panel of
the power supply will be lit dimly. To power the DI LOG on completely, press the on-
off button (18) on the front of DI LOG. ll three LEDs on the front panel of the PSU
will light up and the power indicator LED on the main chassis (17) flashes while a few
relay click softly. Once the front panel display turns on, the DI LOG is ready.
Now is a good time to get familiar with the basic functions and operation of the
DI LOG before proceeding to hook the preamplifier up to your system.
: Before you start making any connections, you should - as always when
working on the wiring - turn off the DI LOG, as well as the other devices in the
system! Do not connect or disconnect RC plugs to/from a UNB L INPUT while the
DI LOG is powered up, since with this type plugs the signal connection makes
contact before the ground, which may cause a very strong buzzing sound which can
under certain circumstances damage your speakers!
# "!"!"' ,
We've tried to limit the number of control elements in accordance with the motto "as
much as necessary, as little as possible". n important design consideration for the
DI LOG preamplifier was to keep the basic functions easy to use and intuitive – e.g.
anyone is likely to associate the large knob (16) with the volume setting, the keys (11)
and (12) with inputs selection, and the button (18) for turning the DI LOG on or off.

Power consumption in standby mode is less than 1 watt, which means you can leave
the DI LOG always in standby mode. If you're not using the Dialog for a longer
period of time (holidays, travel, etc...) you can turn the power supply off completely
with the main power switch (8). In severe storms with possible danger of lightning
strikes, you may unplug the power cord from the C outlet for added safety!

Up to eight modules can be inserted at the back of the DI LOG main chassis. You
need at least one input and one output module, to operate the DI LOG preamplifier.
The display (14) will show an error message if no modules are present. The DI LOG
ships from the factory with at least three modules instaled, unless otherwise
specified. Each module has its own manual, since the DI LOG main chassis is
basically a control unit with a power supply. However, it houses a large part of the
"intelligence" of the entire device, namely the main microprocessor, which contains all
the control software. The modules contain the actual audio circuitry, ie the gain
stages, D/ converters and related electronics, depending on the individual module.

To be used for future software updates.
Since the DI LOG is a modular design, new modules may be developed over time,
which can be added to the preamplifier, hence the need to possibly update the
control software.
You may refer to our website to find out about the latest hardware (modules) and/or
software developments. We will provide the most current software available for free
download from our website. In the DI LOG SETTING menu there is a "info" sub-
menu, which will inform you which software version is currently running on your
