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
