AUDIO ANALOGUE maestro CD PLAYER 192/24 DAC SPECIAL EDITION OWNER’S MANUAL MANUALE D’ISTRUZIONI Manual rev1.
Dear Audiophile, congratulations and thank you for choosing the Maestro CD Player 192/24 DAC SE. You’re now the owner of a unit that establishes a new reference point in the category of high-quality and high-versatility stereophonic products. The Maestro CD reduces Jitter problems thanks to an innovative technology developed by Audio Analogue. The technology is based on a discrete component PLL used to lock the digital signal. The whole chain can deliver up to a 192KHz/24bit digital signal.

represents the digital audio receiver, the PLL one represents the inner PLL (implemented by discrete components) and the SRC is the Sample Rate Converter. The CPLD is a circuit which has the task of selecting and sending the signal according to the mode selected by the user. The “System Clock” represents the clock which is used in the DA conversion. As indicated in the picture, this clock signal can be taken from the S/PDIF RX or from the PLL.
PLL Mode / Modalità PLL PLL SRC x4 TOTAL TIME 26 - 35:42 PLL Mode – This mode is available only when the selected digital signal is the one coming from the CD mechanism. The system clock from the SPDIF RX is sent to the PLL, which, if it can lock to it, regenerates and cleans it reducing the jitter for frequencies higher than 20Hz (according to a second order filter). This improved clock is then used to “re-synchronize” all the signals inside the CPLD.
Menu SETUP The SETUP menu can be entered pressing the switch: “TIME/MENU” on the remote when the unit is not playing (STOP Mode). When the unit is in the menu it is possible to move between the different menu parts using the switches: ▲(2) e ▼(8) on the remote and the switch OK(5) on the remote to enter an inner menu if available and to set and memorize a value or configuration. To go back to the previous level of the menu just press the ◄ (4) button on the remote.

Pressing OK(5) enters a specific submenu where you can enable or disable the SRC and select the Up-Sampling factor. Conferma l’attivazione della modalità PLL. In questo caso premendo OK(5) si entra in un sotto menù specifico dove è possibile attivare o meno il SRC e selezionare il fattore di UP-Sampling. SETUP: PLL 2.
SRC Mode Sub menu Sotto menu Modalità SRC (Sample Rate Converter) SETUP 3. SRC SETUP: SRC 3.1: Exit Exit from the setup menu. Uscire dal menu setup . SETUP: SRC 3.2: SRC ON Confirm the activation of the SRC Mode. Pressing OK(5) enters a specific submenu where you can choose the sample frequency. Conferma l’attivazione della modalità SRC. In questo caso premendo OK(5) si entra in un sotto menù specifico dove è possibile selezionare la frequenza di campionamento. SETUP: SRC 3.2.
Setup selected INPUT Sub menu / Sotto menu di Selezione dell’ingresso The Maestro CD Player 192/24 DAC SE works not only as CD Player, but it can also work like a DAC (Digital to Analog Converter). In fact, it is possible to select the source to play: between the CD mechanism or the S/PDIF input. Il Maestro CD Player 192/24 DAC SE non è solo un CD Player, ma è anche un DAC. Infatti è possibile selezione l’ingresso da riprodurre: la meccanica CD oppure l’ingresso S/PDIF. SETUP 4.
Il Maestro CD Player 192/24 DAC SE permette di memorizzare nel microcontrollore i settagli preferiti per un rapido ricaricamento delle configurazioni. I Preset vengono gestiti mediante i comandi di: Save (salva la configurazione in un Preset) e Load (carica una configurazione precedentemente salvata in un preset) all’interno del sotto menu dei Preset. I Preset sono memorizzati in modo permanente all’interno della memoria del microcontrollore.
Premendo il tasto OK(5) viene caricata la configurazione (che prevede il segnale proveniente dalla meccanica come segnale digitale) salvata dall’utente in questo preset. L’apparecchio carica la configurazione e esce dal menu riportandosi in una condizione di normale funzionamento. Se non è stata salvata nessuna configurazione in questa posizione, sul display viene visualizzato “EMPTY” e se si preme il tasto OK(5) il menu rimane su questa voce.
Premendo il tasto OK(5) sul telecomando la configurazione presente sull’apparecchio verrà memorizzata in questa posizione di preset. L’apparecchio salva il preset e esce quindi dal setup tornando ad una funzionalità normale. Note**: the presets “CD” and “DIN” require the selection of a specific digital input in the currently running configuration to be saved.
