LAG Digital. Big Bang DAC.

Pitch-perfect digital-to-analog converter.
For professionals and music lovers.

All LAG High-precision music systems are analog audio equipment. At the same time, the modern world of digital music and storage mediums make it necessary to use digital-to-analogue conversion devices for the subsequent amplification of the obtained analogue electrical signal during sound reproduction.

LAG BIG BANG DAC is the only digital-to-analog converter on the market that allows you to fully preserve the integrity of a digital music signal in the process of converting it to analog. A key feature of the digital-to-analog converter BIG BANG DAC is the complete absence of internal signal processing in the device path. Digital signal recovery is carried out bitwise and without even the slightest delay. The BIG BANG DAC internal construction contains no feedback circuits and amplifications for both the input and output signals.

LAG BIG BANG DAC is built on the principle of per-channel signal processing. Each channel is processed by an independent mono-module. This design completely eliminates the interpenetration of signals from adjacent digital (input) and analog channels (output).

The use of digital-to-analog LAG converters in cascades of sound reproduction of monitor complexes of professional recording studios, as well as a part of premium home audio systems, allows for “live” music playback not only from analog media, but also from digital content sources.
