The all-new Thorens preamplifier The TEP 3800 is an analogue valve pre-amplifier at the heart of which consists an unprecedented circuit design: the counter-parallel amplifier. As opposed to customary circuitries, this has been designed with a fully balanced layout and it is entirely DC-coupled. Another outstanding feature is the extremely low output impedance of the triode stage, which can do without any output transformers. The bias of each strictly selected valve is elaborately supervised. The use of digital micro-processors within the circuitry however has consciously been omitted in order to ensure that no digital garbage can spoil the analogue signal. The fully balanced volume control renders music in all its sonic beauty and fidelity, at any position. Provided with balanced as well as unbalanced inputs and outputs and in addition is well equipped to work in combination with home cinema components as well. The perfect partner for the powerful Thorens monoblock amplifiers TEM 3200. Comes with a special remote control. Highlights: 1. A tube power-amplifier with no output transformer; the output impedance is lower than 1 Ohms = world record for pure tube-output Preamps! Connection of cables with a length of more than 100 yards and/or use of high capacitive cables is no problem. 2. Absolutely new, patent pending structure: two independent and 100% ground-free current loops create the power amplifier stage = not even 1 microamp of cable- or load-induced current is flowing in the voltage amplifier stage nor the ground = best transparency and cleanliness. 3. 100% symmetry + 100% DC-coupling + 100% ground-free current loops of the power stage + 100% control of all working points under all conditions = Blˆhbaum System (TM) = worldwide unique circuitry for wonderful combination of control and transparency with musical flow and emotion. 4. Use of 12 NOS tubes: 6 per channel, only the best quality for military and professional broadcast (like NOS Siemens C3g for Deutsche Post) are used. The output tubes have a extremely high mutual conductance of more than 40mA/V and ensure lowest output impedance, extremly low noise and very wide bandwidth. 5. Allmost 6 input channels are available, two of them are switchable between XLR and Cinch-connection. 6. Every non-symmetrical signal (Cinch-Inputs) is converted into a true symmetrical signal with the highest possible quality; all signals are amplified in the symmetrical domain. 7. Innovative volume regulator with Zoom-Function of the most common regulating range for modern signal sources like CD-players 8. Two independent usable outputs (XLR and Cinch), XLR output is designed according to studio standards. The perfect partner for active studio speakers. 9. Extremely low noise and hum and very wide bandwidth (more than 600kHz!) due to the patend-pending circuitry in conjunction with tubes from the world of professional broadcasting and military radar.
