SCOPE OF SUPPLY
The scope of supply comprises:
•TRINITY PREAMP (440mm x 50mm x 300mm plus 15mm stainless steel feet, eight 8kg)
•TRINITY Remote Control ( ith USB charging cable)
•TRINITY XLR cable (optional)
•Cotton gloves
•Cleaning cloth

TRANSPORTATION AND CLEANING
Please only transport the parts listed in the scope of supply in the supplied flight case and use the supplied cotton gloves
hen unpacking and installing the appliances to avoid scratching the enclosures.
Clean the surfaces using the supplied microfiber cloth: immerse the cloth in luke arm ater containing no detergents and
then carefully ipe the surface hen the cloth is almost dry.
Never use chemical or a ressive deter ents.

SELECTING THE POWER VOLTAGE
The implemented ide-range s itched mode po er supply modules allo an operation from 100Vac to 240Vac. The t o
fuses on the primary side are placed inside of these modules.
CONNECTING AND STARTING
To install the PREAMP, select a stable, level surface directly next to the turn table so that the connecting cable to the tone
arm is as short as possible. Avoid placing the appliance in direct sunlight and never place the modules directly next to
radiators or fan heaters.
Protect all supplied parts from humidity and moisture.
Only ire up the components hen the device is s itched off.

WIRING UP
1. Disconnect the PREAMP from the po er source. Never disconnect any ires unless the device is s itched off.
2. Connect the PREAMP to the sources like DAC, PHONO and so on.
3. Connect the PREAMP to the POWER AMP.
4. Charge the Li-Pol battery of the remote control ith the enclosed USB-DC cable, if necessary.

THE LOW NOISE INPUT STAGE
The TRINITY PREAMP is based on the same architecture of the TRINITY PHONO. It uses the same extraordinary gain stage,
hich is based on 12 ultra-linear fully differential gain stages.
The PREAMP is fully balanced from the input to the output.
The TRINITY PREAMP uses 12 gain stages in parallel to reduce the input noise voltage by a factor of
12 3.5 10.8dB= ≡
The Gain can be set during the assembling. The regular gain is 6dB, other gain can be realized on request.
Another advantage of using 12 gain stages is that the load of the volume control is split to 12 gain stages. That means each
gain stage has only to deliver 1/12 of the necessary current and therefore stays in a Class A mode for all possible signal levels.
The DC servo allo s single ended adapter on each input connector.
