1. Preface
Dear TRIGON - client,
Your made up your mind for the pre-amplifier TRV-100. This equipment was
produced in response to severe production-controls and it is an excellent example for
modern precision-technic.
Even if you are already familiar to the handling of HIFI equipment you should study
this instruction carefully and act according to the herein instructions.
Please save this instruction carefully because it can surely be a good help again
while running your pre-amplifier.
Have a good time with your new pre-amplifier.
Your TRIGON-TEAM
2. General description of the equipment
The TRV - 100 is a pre-amplifier of high quality with eight high-level-inputs and two
separately switchable outputs. Two of the eight inputs as well as one output are
supplied in symmetrical design. The inputs 7 and 8 can also be used as input for a
tape-recorder because there are also two record-outputs belonging to these two
inputs.
There are also two switched low-voltage-outputs (10V DC) for the running of amplifier
and active loudspeaker with DC-remote control. Further TRIGON-equipment,
controlled by the TRV - 100 can be connected to a 3-pole-D-sub-socket.
For the running of a high-ohmic head-phone there is a 6,3 mm phone plug at the
front of the equipment.
Further the TRV - 100 has got an input/output where special equipment like
Surround Decoder, Equalizer etc. can be connected.
The amplifier is completely controlled by a uP in consideration of a good working
separation of the analogous and digital circuits.
The operating of the pre-amplifier is possible at the equipment itself as well as by a
IR-remote-control-unit. A clear display on th front of the pre-amplifier, which is
dimable and can be switched off, informs always about current positions. In the
„Stand-by Modus“the equipment can be switched-off by remote-conrol-unit.
Independent from the current program the Record-circuit allows copying any
program-source.
The volume can be adjusted by a special D/A-converter, so it is much better than
conventional volume control(Pontentiometer) in respect to sound and technology.
Each of the amplifier stage is produced modulary, in the case of developments
concerning the technology or the sound they can be exchanged by unplugging.
The integrated toroid transformer with a „Super Silent material“ which is low magnetic
field and humless runs even very well in the case of unclean voltage. Again the
mains-part was very much considered. It consits mainly of four separat mains-parts
4
and contains for the supply of the amplifier stage a special connection, which always
allows a low sorce resistance in the case of higher frequency . That way the distortion
occuring also in the high-sound-sphere wil be minimated and the sound seems to be
less rough comparing to the use of usual connections.
2.1 Security-advices

3. Start
After unpacking the pre-amplifier we recommend first of all to connect the equipment
to the power-line and to switch it on before connecting it to further equipment.
After a short starting-phase (the sign LED is gleaming) you will hear a soft noise
caused by some relays and now the now the TRV-100 is ready.Now you should get used to the operating-instruments and to the connectingsockets.
Try to work with all operating-functions. You cannot destroy anything.
If you tryed everthing and have understood the function of the TRV-100 you can start
the connection of the cables.
If you have already stored within the MODE-Function it is recommended to recall the
storages (keep the MODE-key pressed for ca. 5 seconds)
If working at the cabling in any case you should switch off theTRV-100 as well as the
rest of the system.

by leaking batteries.
4. Examples for connection-possibilities
4.1 Which equipment can be connected ?
The TRV 100 is concepted as a pure high level amplifier. All units of the
audioelectronic can be connected, which offer a linear, anolg signal voltage between
0,2 voltage and 2 voltage. Such units are for example: Tuner, CD-Player with
integrated DA-converter tape-recorders, cassette-players, HIFI-Video-recorders etc.
Effect-units like equalizer, tone control amplifier, surround-decoders etc. can be
connected at the socket-pair Split
Microphones and record-players cannot be connected.
4.2 The input-sockets
The TRV 100 has got 8 inputs. The inputs 1 and 2 are concepted as symmetrical
inputs ( Pin 1= GND, Pin 2 = + not inverted, Pin 3 = inverted).
A SPLIT-input offers an extra input. If this socket is used as input, please take care
that this input won't be connected onto the tape-outputs.
4.3 Connection of recording units
The TRV 100 has got 2 record-outputs (19). Hereon the record-inputs of cassetteplayers, tape-players and the analogous-inputs of a DAT or MD-recorder can be
connected.
12
4.4 Recording possibility between two recording-units
In order to record between two recording units please connect the outputs of
recording-unit A to the input 7 and the outputs of unit B to input 8. The recordinginputs of unit A should be connected to Tape outputs Rec-1 and of unit B to Tape
outputs Rec-2.
If you now want to record from unit A to unit B, please switch the RECORD-path on
position 7. Therefore you have to switch button 4 (RECORD) and move the knob 1 to
position 7. Now the recording can be started.
4.5 The output sockets
The TRV 100 has got two outputs which can be switched undependent from each
other.
To these outputs usually a power-amplifier or an active-speaker can be connected.
With output 1 there is an asymmetrical and with output 2 a symmetrical output
available.
The symmetrical output is good to use in the case of very long connection-cables
between pre-amplifier and amplifier.
The advantage of a symmetrical cabling is that jammings going on to such lines will
be effectively suppressed.
The pin-engagement is as follows: Pin 1 = GND, Pin 2 = + not inverted, Pin 3 =
inverted.
4.6 Remote Sockets
Some power amplifier and active-speakers can be switched on and off by using a
DC-voltage
. Therefore the TRV 100 has got two REMOTE-sockets with a DC-
voltage of 10V as soon as the TRV 100 has been switched-on.. Nevertheless the DCvoltage can be switched-off within the MODE-Menue.
4.7 Connection of an equalizer
In order to build an equalizer into the signal-line, the TRV 100 has got a socket-
quartet with the mark SPLIT (18).
Connect the output of the equalizer to the sockets INPUT and connect the output of
the equalizer to the sockets OUTPUT.
In order now to build the equalizer into the signal-line, you only need to press the
button SPLIT at theTRV 100 or at the remote-control-unit.
13
4.8 Connection to a surround-unit
The TRV 100 offers the possibility to integrate a surrounddecoder into your HIFIequipment in an easy manner.
In the case of a surround-unit usually at least 5 independant speakers have to be
steered. In order to use the two main-speakers of the right and left channel without
disconnecting, you have to connect the surrounddecoder as follows:
The input of the surrounddecoder has to be connected to the sockets of SPLIT
OUTPUT (18). The output-sockets for the main-channels front left and front right
have to be connected to the sockets of SPLIT INPUT (18).
By pressing the button SPLIT the main-speakers are now connected to the surrounddecoder by using the main power amplifier.
The power amplifier for the two backward channels and of the middle channel will be
directly connected to the surround-decoder.
In order to adjust the total-volume at the surround-decoder you adjust the volume at
the TRV 100 to factor 73. Now you adjust the surround-unit according to the
instruction.of the surround-decoder. The volume at the TRV 100 shouldn't be
adjusted any longer.
Now the unit is adjusted for the surround-function.
Here are the adjustments for the surround-function in tops:
14
Example: The Videorecorder is connected to the TRV 100 at INPUT 5. The
surround-decoder is cabled as above.
1st step : switch the TRV-100 on SPLIT.
2st step: put the volume at TRV-100 to factor 73
3rd step: select input 5 at the TRV-100
4th step: switch the surround-decoder to input 1
5th step: adjust the unit according to the instruction of the surround-decoder.
6th step: start the reproduction at the video-recorder
5 The FunctionMODE
Some extra functions are called if calling this button. At the moment the following
functions are available:
- Adjustment of the stereo-balance
- Adjustment of the display-brightness
- level adjustment for each input
- adjustment of the basic-volume
- basic adjustment ex-factory
If pressing the button MODE you get into the special-function-modus and the signal
MODE is sparkling. With every further pressing of the button the menue changes to a
further function, after the 6th pressing you will leave the MODE-Menue. If you want to
store an adjustment for a longer time you'll have to keep the MODE-button pressed
for an instand. During this time the sparkling of the MODE-signal stops for a short
time. As soon as the signal starts sparkling again the adjustment is stored durably
until it will be overwritten by another adjustment on the same way.
The adjustment-possibilities are described as follows:
5.1 Adjustment of the STEREO-Balance
After the first pressing onto the MODE-button you'll find yourself in the modus
BALANCE: The display shows the following picture, while the MODE-signal is
twinkling and the upper light in the middle (LED) is shining.
INPUT
RECORD SPLIT OUT 1 OUT 2 MODE
By turning the VOLUME-button to the left or to the right the stereo-balance can be
adjusted. Dependend on the turning-direction of the balance there will be another
LED shining in order to inform you about the changing of the direction.
The volume-display shows the level of the changing. One changing-unit means 1dB.
15
A maximum difference of 100dB can be adjusted. When you have found the right
adjustment it can be stored as described above. By using the MODE-button another
time you will jump into the next menue. But if you want to stop the adjustments, the
amplifier will leave the MODE-menue automatically after ca. 10 seconds and the
MODE-signal as well as the signal-LEDs will stop shining. Again the volume-display
shows the actual volume-factor.
5.2 Adjustment of the display-brightness
The brightness of the entire display can be pre-adjusted in three steps. In order to do
this adjustment please press the MODE-button two times, so that the numeral-signal
above from the RECORD-signal shows a symbolical „h“
INPUT
RECORD SPLIT OUT 1 OUT 2 MODE
By turning the VOLUME-button you can adjust the brightness. The display shows the
selected step
When you found the right adjustment you can store it durably as described above.
By using the MODE-button another time you'll jump to the next menue. But if you
don't want to adjust any more, the amplifier will leave the MODE-menue and the
MODE-signal and the signal-LEDs will stop shining as well. Again the volume-display
shows the actual volume factor
5.3 Adjustment of the input-level
Sometimes it can occure that the equipments connected to the TRV-100 have got a
different volume and that there are volume-differe14nces if switching over. TheTRV-
100 offers the possibility to adjust the sensibility of each input individually. At the third
position in the MODE-modus occures the function level. With the INPUT-knob you
can select the input which input-level you want to change.. With the volume-knob
then you can lift the level (turning to the right) or let the l evel down (turning to the
left). The volume-display shows you the degree of the lifting/sinking. With the lifting
the upper LED on the left side is shining additonally, with the sinking the downer LED
on the left side is shining
16
INPUT
RECORD SPLIT OUT 1 OUT 2 MODE
Input level adjustment: INPUT 3 is selected and lifted by „4“ (2dB)
Having adjusted the level the MODE-button has to be pressed for some seconds
(until the MODE-signal is twinkling again) .. That way the level-adjustment for the
selected input is stored.
If you want to work with further input-level please select the the next entrance with
the INPUT-knob and operate as described above.
The adjustment-possibility overwrites+- 6dB in steps of 0,5dB, that means 12 digits
up and 12 digits down.
If you want to finish the adjustments, the amplifier will leave the menue automatically
after 10 seconds.
5.4 Adjustment of the basic-volume
The TRV 100 has got an elctronial volume-adjustment. This operation offers a better
reproduce-quality (in comparison to a convenient (Potentiometers) and advantageous
extra-functions. One of them is the adjustment-possibility of the basic-volume. That is
the volume-level, which adjusts itself automatically after switching on the preamplifier. Even when you have switched-off the OUTPUTS for instance in order only
to listen with head-phones, the basic-volume will be adjusted automatically after
switching-on again. That way it is assured that a high positioned volume-level
adjusted like that before the last switching-off, will sound immediately at the output at
the speaker.
But the basic-volume can be pre-adjusted in the MODE-menue by yourself.
Therefore you switch the MODE-button and you get at the fourth position to the
adjustment-modus of the basic-volume.
17
INPUT
RECORD SPLIT OUT 1 OUT 2 MODE
With turning the VOLUME-knob basic-volume can be changed. When you have
adjusted a level again the MODE-button has to be pressed for some seconds (until
the MODE-signal is twinkling again) and the basic-l
evel-adjustment is stored.
If you want to stop the adjustments, the amplifiers leaves the MODE-menue
automatically after 10 seconds.
5.5 DC-Remote Switch-on and-off
The TRV-100 has got the possibility to offer a 10 voltage DC-voltage for remote
control Such a DC-voltage is demanded fron several power amplifier and activespeakers in order to get switched-on at the same time as the pre-amplifier.
Sometimes it can be an advantage to switch-off this remote voltage.That happens for
instance if listening only by head-phones and the power amplifier isn't needed.
At the fifth position of the MODE-menue you get to the switch-on/switch-off modus.
The following picture appeares:
INPUT
RECORD SPLIT OUT 1 OUT 2 MODE
With the volume-button a factor of 00 or 01 can be adjusted. OO means, that the
REMOTE-signal is switched-off an 01 means that the REMOTE-signal is switchedon. In order to store the adjustment again keep the MODE-button pressed for some
seconds until the MODE-signal is twinkling again. In order to leave the MODE-menue
press another time the MODE-button or wait some seconds until the amplifier leaves
the MODE-menue automatically.
18
5.6 Basic adjustment ex-factory
Ex-factory the TRV-100 is supplied with a basic-position. If you are not satisfied with
the adjustments in the MODE-menue and want to reproduce the ex-factory
adjustment, please keep the MODE-button pressed for some seconds (but you
shouldn't be in the MODE-menue, that means that the MODE-button is not twinkling
at the moment). As soon as you press the MODE-button for some seconds the
MODE-signal starts twinkling sometimes and the original-adjustments are
reproduced. But please take care that all your adjustments (balance. displaylightness, basic-volume etc.) will be overwritten.
6. What to do if...
In this chapter we want to ease for you to localize and to remove small faults
6.1 ... nothing happens ?
Is the plug put-in properly ? - Put-the plug regularily into the socket.
Is the used socket connected to the AC-voltage or is it connected to the home fuse
box. Check the home fuse box.
Did the internal fuse blow? - Send the equipment to the service.
6.2 ... nothing is to hear ?
Did you select the right input? Select the input which shall be heared.
Did you switch-on the used output? -Switch-on the output.
Does the source supply a signal? Switch-over to another used input and check if this
one is working. If it does, the other source has a fault. - Check this source.
Is the MUTE-Function active? Press once again MUTE on the remote-control-unit or
just change the volume?
Is the Split-Function select though there is no extra-unit connected? Deactive the
SPLIT-Function.
6.3 ...it is humming ?
Did you put in the connection-lines unshaky and are they fixed? - Check the
connecting-cable.
Sometimes there are so called huming loop caused by multiple grounding.
In order to solve this problem some experience is necessary. We recommend to
connect your distributer.
19
It is only humming if the tuner or the video-recorder or the television-set is connected
to the pre-amplifier. -All these units are connected to the aerial which itself is earthed.
So there is from time to time a humming loop which in this case can easily removed
by the use of a AC-filter.
6.4 ... the remote-control-unit does not react ?
Does the remote-control-unit operate in the pre-amplifier-modus at the moment?
Press the button PREAMP on the remote-control-unit. Now the remote-control-unit is
activated for the pre-amplifier.
Are the batteries finished? - Put in new batteries.
Is the distance too great?- Decrease the distance. IR-remote-control-units too have
only got a certain reach. With well loaded batteries up to eight meters.
The reach will decrease as well if too bright sunlight is disturbing. Avoid direct
sunlight.
6.5 ... there is no remote-signal ?
Did you switch off the remote-signal? - Switch-in the remote-signal into the MODEmenue.
Did you put in the connection-cable properly? - Check the connection-cable.
