Dear Audiophile, Congratulations and thank you for choosing Maestro Settanta. You’re now the owner of a unit that establishes a new reference in the category of high-quality and high-versatility stereophonic products. Maestro Settanta provides circuital solutions with no compromises and features capable to satisfy advanced users’ demands.

Unpacking and checking CD player package Carefully open the package to avoid damaging the content. The package should contain: • 1 Maestro Settanta • 1 remote controller • 1 power cord • 2 AAA batteries (already placed in the remote controller) • 1 instruction manual If one of the items listed above is missing, please contact your Audio Analogue retailer. After extracting the smallest items from the package, pull out the unit carefully. Separate the package from the anti-shock expanded-foam protections.
Powering up Maestro Settanta When you plug Maestro Settanta into the power outlet, the unit automatically turns on in the STANDBY mode. This is intended to prevent the unit to suddenly turn on after power interruption. When the “STBY” button on the remote controller is pressed or a knob on the front panel is turned, the amplifier turns on and a presentation message is shown on the display, followed by the indication of the amplifier status.
Volume settings and silencing (mute) The volume knob on the front panel and the Vol+/Vol- buttons on the remote controller change the general sound level. It means that the volume of the two channels is altered identically. It is possible to modify the relative level of each channel changing the balance option in the setup. The mute buttons on the front panel and on the remote controller allows lowering the sound level by 20dB.
Notes on inputs bypassing Maestro Settanta has a set-up option that allows using it as a power amplifierl. In this case, you may choose which of the six inputs you like to use. When this option is activated and chosen, pre-amplifier gain is reduced to 0dB and you may select the input to bypass. Your selection can’t be changed until you deactivate this function. This option is very useful when you want to integrate the amplifier into a multi-channel audio/video system.
Standby mode You can put Maestro Settanta in standby mode pressing the “STBY” button on the remote. When the amplifier is in standby mode, only the microcontroller section is powered while the rest of the circuit is off. In this case, the display on the front panel is off and the power led lights blue. To exit the standby mode, just press the “STBY” button on the remote controller or turn one of the knobs on the front panel.

Troubleshooting Symptom Display is off No sound Cause Power cord incorrectly plugged Burned-out fuses Display is on No sound Remedy Make sure the power cord is correctly plugged into the wall outlet Check fuses in the fuse panel (after unplugging the power cord from the wall outlet) above the IEC inlet and replace them with new ones of the same type Low volume Faulty or incorrectly plugged connectors between Maestro Settanta and the speakers Turn volume knob right Check cords and their connection O
RICERCA GUASTI Sintomo Display spento Nessun suono Causa Cavo di alimentazione non correttamente collegato Fusibili di rete bruciati Rimedio Controllare che il cavo sia ben inserito nell’amplificatore e nella presa di rete Controllare i fusibili nel portafusibili (dopo aver staccato il cavo di alimentazione dalla presa di rete) sopra la presa IEC ed eventualmente sostituire con altri dello stesso tipo Volume regolato al minimo Cavi di potenza tra Maestro Settanta e diffusori non connessi corretamente
