User manual BLUENOTE S-1

[. . . ] BLUENOTE® is a range of products of prestigious and sophisticated Italian design featuring unique and innovative technical and aesthetic characteristics. The STEROID 1 Signature is a single ended Dual-Mono solid state stereo integrated amplifier that uses a proprietary Bluenote electronic design called Mirror-AmpTM. The Mirror-AmpTM enables the preamplifier section to work as a super class A amplifier. The Mirror-AmpTM is a the gain stage made with a proprietary cascode differential amplifier with a mirror current, producing a super-linear signal, thus virtually eliminating distortion. The power supply is handled by three different transformers custom made for Bluenote. [. . . ] In any case, take care to switch OFF and detach the AC power chord from the AC wall plug the S - 1 \integrated amplifier every time you need to move it. The high weight of the amplifier is not suitable to be positioned on any other components of the hi-fi system. Operating Conditions Once it has been correctly mounted and wired with its AC power Chord, and once the unit is been wired to a line input of the amplifier with a proper interconnect cable, your STEROID Signature integrated amplifier is ready for use. TO PREVENT HIGH QUALITY SOUND PERFORMANCES THE S - 1 DOES NOT HAVE ANY OUTPUT PROTECTION. SHORT CIRCUIT OR WRONG SPEAKERS (BELOW THAN 4 OHMS) MATCHING IRREMEDIABLY DAMAGE THE AMPLIFIER OUTPUT BOARDS AND THE OTHER UNITS CONNECTED TO IT. THE UNIT IS PROVIDED WITH FOUR THERMAL SWITCHES PUT ON BOTH CHANNELS HEAT SINKS AND POWER TRANSFORMERS. BEFORE THE UNIT REACHES A DANGEROUS TEMPERATURES IT TURNS OFF AUTOMATICALLY UNTIL IT WILL COLD DOWN TO A REGULAR OPERATING TEMPERATURE LEVEL. IF THE UNIT TURNS OFF DURING PLAYING SWITCH IT OFF AND WAIT 30/60 MINUTES. SWITCH ON AGAIN A CHECK EVERYTHING IS BACK NORMAL BEFORE CALLING ASSISTANCE FOR SERVICE. NOTE: Never disassemble any part of the product for any reason whatsoever.

Once installed you can switch MM and MC operating by moving the small DIP SWITCH with 4 Micro-Switches that is positioned internally closed to the external DISC input RCA connectors. The Micro-Switches 1 & 4 are able to vary the Gain of the unit: with the Micro-Switches towards the NUMBERS SIDE the De Medici operates in MM mode; with Micro-Switches towards the ON SIDE the De Medici operates in MC mode. The Micro-Switches 2 & 3 are able to vary the load impedance of the unit: with the Micro-Switches towards the NUMBERS SIDE the De Medici operates with a fix 47Kohm (right for all MM cartridges); with Micro-Switches towards the ON SIDE the De Medici operates with a 470ohm (default) or changing the resistors (optional) with the unit with a specific load as requested by the user.

Panel features 5 S -1 Italian Prestige Integrated Amplifier Volume Control The volume control of this unit is made with an high quality potentiometer made by ALPS. It is very precise and its error track ability is very low. Besides it is made with such materials that render its durability far superior with many other potentiometers on the market. The remote volume control with its proper electronic board and power transformer (to avoid any kind of interferences on signal path) works directly on a DC motors positioned on the back of the potentiometer to avoid the use of electronic controllers can reduce sound quality. B e careful during the remote use: the remote moves the volume very slowly when the triggers UP or DOWN are maintained pushed.
