The Orchestra Reference from Jadis belongs to the family of Tube stereophonic integrated amplifiers. The integrated amplifier combines a pre-amplifier and a power amplifier in one device, so it can directly accept the signal from the respective source (cd/dvd player, turntable, radio, etc.) and transfer it to the speakers for playback. In this case, it operates with tubes, so it has a warmer and more natural sound.
Note: In the case of connecting a turntable without an integrated preamplifier, you will need to connect an intermediate and separate preamplifier.
