3D Lab NANO NETWORK PLAYER SIGNATURE V5

The NANO PLAYER SIGNATURE player takes the basics, functions and connectivity of the NANO TRANSPORT SIGNATURE to which a DAC has been added. The NANO NETWORK PLAYER SIGNATURE is equipped with a high-performance 32-768 PCM and DSD converter in 8x native mode, a jitter reduction circuit and clock reformatting provide exceptional performance. The result obtained is far superior to the best standards of CD players. The NANO NETWORK PLAYER SIGNATURE is equipped with unbalanced analog audio outputs (CINCH). These players are much more than classic network players. They have neither PC card nor switching power supply. They are therefore non-polluting. They provide high-level audiophile sound, outperforming even the best sources of all products. Many audio players for dematerialized music are generally PCs disguised as audio players. They are very polluting and can in no case be good audio players. In Nano players there is no element that can cause an alteration of the signal. This 32bits-768KHz & DSD 22.4 PLAYER is ultra complete. AIRPLAY, it is compatible with AUDIRVANA, JRIVER, QOBUZ, TIDAL, SPOTIFY, ROON, HQPLAYER, SQUEZZEBOX, AIRPLAY, BLUETOOTH, Etc … Equipped with 4 USB ports, 2 USB2 and 2 USB3. It reads USB sticks and hard drives, so it can be an audio server. The RJ45 network speed increases to 1Gb. Sound file: PCM, WAV, DFF, DSF, AAC, FLAC, M4A, MP3, OGG, ALAC, WMA, AIFF, etc….. A player with incredible features, it has extraordinary musicality, without a doubt one of the best players in the world. These are not PCs disguised as audio players, just a very powerful FPGA with a linear power supply. A computer is an excellent choice for storing audio files, it is a poor player. It is by no means a player without compromises. In NANO players the digital signals are completely reformatted and resynchronized. A powerful anti-jitter equips Nano players. The specifications are at professional standards. Nano players have uncompromising features, they can be used in multi-room systems, with one or more servers, one or more controls. Server: Nano players can be used with computer servers, NAS, tablet, smartphone, PC, MAC, box, etc. Multiple servers can be used in the same installation. Multiroom: Nano players can be used in Multiroom, it is possible to use multiple players in different rooms, while playing audio files specific to each room. Each player can be called with its own name. This simplifies multi-room systems. A powerful tool (HTML page) allows all kinds of control, including direct player update via the network. Equipped with a dual clock with a phase noise of -173dB, this player has exceptional characteristics. The sound flow management is carried out with a very powerful FPGA. A pico calculator acts as management of the various applications, the sound production is entirely shaped and decoded by the FPGA. Finally, the power supply is external to the main box in order to limit any noise interference. A second power supply with 2 circuits 3.3v and 5v is installed in the main box as close as possible to the various circuits in order to limit noise as much as possible. Usage: Nano network readers are controlled by tablet, smartphone, PC, Mac, etc. Many applications are possible. The system being completely open, the possibilities are endless. The user is free to choose. The software part is free and scalable: many solutions on PC, MAC, GSM, TABLET (in iOS or Android). The technique Volume adjustment World first on a network reader, LEEDH PROCESSING It is possible on the NANO PLAYER, SONATA, PLAYER, and SIGNATURE to adjust the volume. In fact, by going through the HTML page of the player, it is possible to put the latter in fixed or variable volume mode. On the SIGNATURE, there are two levels of fixed mode. Volume control is a very delicate subject, because it is destructive of sound quality in both analog and digital. The perfect sound is a sound at 100% volume. But in everyday use this is impossible (deafness, neighborhood, etc.). By attenuating a signal we cause a compression of the dynamics, a loss of precision, an increased distortion rate. In short, the sound is distorted. In most cases the listener listens at -40dB (0 being the maximum, the volume is generally done by attenuation). The sound is therefore modified. LEEDH PROCESSING is an algorithm that pushes back the degradation of the signal and therefore in normal use does not cause any modification of the signal. The result is spectacular, the music keeps its dynamics and precision. The much more natural sound keeps its originality. Dual Power In order to achieve the lowest possible noise and to avoid having 230 volts in the main box, the power supply is made in two parts. A first box lowers the voltage to 9 volts. A second very high performance power supply is in the main box. The overall noise is therefore massively reduced. ULNP: Ultra Low Noise Power Supply The power supply of the players uses very high-performance circuits to obtain noise levels never before achieved in the world of audio. The noise of the power supply is 1µVRMS, and 0.8µVRMS on the Signature models. ULNC: Ultra Low Noise Clocking The clocks that equip the network readers are very high-tech and allow for exceptional precision. The phase noise on the Signature models is -173dB. Super Synchronization The FPGA architecture allows perfect synchronization of digital signals. The I2S bus is perfectly synchronized. The jitter rate is at a record level never before achieved; it has never been so low in a network reader (see below: conclusions) Super Short Design Thanks to the FPGA architecture the number of stages and circuits is reduced to a minimum. The FPGA performs all the basic functions, receiver, transmitter, buffer, multiplexing, synchronization, the noise and jitter level is drastically reduced. One circuit replaces all the usual circuits. Super Monitoring Flux In order to obtain the lowest possible jitter level, the FPGA enslaves the nanocomputer which acts as an IP stack. The network flows are captured by this nanocomputer on the intranet and internet networks. The audio flow is entirely controlled and managed by the FPGA. In electronic language, the nanocomputer is the slave, the FPGA the master. In a classic architecture where the nanocomputer is the master (the vast majority of solutions available on the market) the jitter rate on the I2S bus is 1000 picoseconds. Thanks to this innovative technology (SMF), the rate collapses to 36 picoseconds, which is colossal. Conclusions: Comparison of the jitter rate on the I2S bus of the different technologies used in digital audio. Measurements made using the Tektronix MSO64 – 25GHz (average RMS jitter over several seconds): A very good CD player = 7.22 nanoseconds or 7220 picoseconds A good network reader = 1.40 nanoseconds or 1400 picoseconds A very good USB bus = 0.645 nanoseconds or 645 picoseconds (Amanero) A very good network reader = 0.63 nanoseconds or 630 picoseconds (with reshaping and reclocking of the I2S bus) V2 3D Lab (Engineered) readers = 0.3 nanoseconds or 300 picoseconds V3&4 3D Lab readers (FPGA 3D-Lab) = 0.036 nanoseconds or 36 picoseconds   Noise Power Supply Noise Clocks CHASSIS FPGA & CLOCK SONATA 1µVolt & 1µVolt -155dB/Hz classic damped TRANSPORT 1µVolt & 1µVolt -169dB/Hz classic damped SIGNATURE 1µVolt & 0.8µVolt -173dB/Hz heavy damped   DAC VOLUME CHASSIS SONATA AK4490 LEEDH classic damped PLAYER AK4490 ** LEEDH classic cushioned SIGNATURE AK4493 ** LEEDH heavy damped ** Super DAC filtering on PLAYER and SIGNATURE 1 x RJ45 2 x USB 2.0 2 x USB 3.0 2 x Iesiri analogice 1 x S/Pdif Out 1 x TOS-LINK Out 1 x I2S Out
