Analogue preamplifier & high performance DAC
TELEMANN has a build in DAC which is better than any other stand alone DAC you can buy. So, no need for an external device. If you do not want or need to use the digital inputs, never mind, just use the high performance analog preamp section.

Description

Analogue preamplifier
G.P. TELEMANN (GPT) is a crème de la crème analogue preamplifier for all common signal sources, be it digital (due to the inbuild D-A-converter), analogue, symmetrical (balanced) or single-ended. Signal processing inside the GPT is strictly balanced, making it the ideal control centre for a fully balanced audio system. The high and stable output drive enables long cable runs to the power amplifier with zero phase-shift across the entire frequency spectrum.

Volume control
Controlling the volume is one of the most trivial and at the same time most demanding tasks in audio engineering. The circuit is fully symmetrical and high frequency capable at the same time. For this reason the characteristic impedance of the attenuating ladder arrangement matches the impedance Z of the microstrip differential signal pair used throughout the GPT.

Fast transient response – ultra wide bandwidth
The rise time for a 2 V step is only 35 ns. It’s incredibly fast. 2V is almost all it takes to get full output from a downstream power amplifier. Bandwidth corresponds to speed and vice versa. In this case it is a whopping 3.5 MHz. So GPT is really ultra-broadband, 175 times more than the audio bandwidth. Some may view this as technical overkill, but it is not ! The result is increased transparency, less grain and more music.

Digital-to-Analogue-Converter
By keeping the recipe and refining the ingredients, digital to analogue conversion is carried out by the ES9038 PRO, incorporating innovative circuits delivering spectacular music free from annoying artefacts. 4x balanced 32-bit D/A converter per channel pass over audio to our proprietary discrete analogue circuits. A novelty at LINNENBERG AUDIO: the DAC board is upgradeable at any time should this be necessary or making sense.
