The DAC-Pre is DA converter and preamplifier in one device. It offers a high -end converting by Texas Instruments PCM1704 IC and 3. order Filter. It can be co
nnected by coaxial input stage. This device is to be settled by the employment of high-quality parts sounding on highest level. The condensers in the filter are selected by hand. As operation amplifiers LME49710 for filtering and audio output are used. The LME49710 operational amplifier reproduces the sound more natural, offers the best precision and so the best equality between the two channels. The device can work with frequencies from 32 to 96 kHz. The output filters (3.Order) are doubly present. Per one for the frequencies 32-48 kHz and one for 88 and/or. 96 kHz. Thus HF portions are filtered in the best way out. Optional symmetric output stage can be implemented. It works with the famous SSM2141.
Sound: By the complex circuit of converting and filtering the sound is very warm and calm. Details are precisely worked out. The lower frequencies wins at outline. The higher frequencies losses in opposite to other DACÂ´s the sharpness. With a good cable connection between transport and DAC it changes sovereign each digital information into an alive spraying sound.
The volume control (optional) works with two stages. Between them the ALPS poti is to be settled. It can be controlled by remote.
