IMPORTANT SAFETY INFORMATION

1 Read these instructions.

2 Keep these instructions.

3 Heed all warnings.

4 Follow all instructions.

5 Do not use this apparatus near to any water.

6 Clean only with dry cloth.

7 Do not block any ventilation openings. Install in accordance with the manufacturer's instructions.

8 Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.

9 Do not defeat the safety purpose of the polarized or ground-ing-type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong are provid-ed for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.

10 Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus.

11 Only use attachments/accessories specified by the manufac-turer.

12 Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over.

13 Unplug this apparatus during lightning storms or when unused for long periods of time.

14 Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate

normally, or has been dropped.

• Do not expose this apparatus to drips or splashes.• Do not place any objects filled with liquids, such as vases, on the apparatus.

• Do not install this apparatus in a confined space such as a book case or similar unit.

• The apparatus draws nominal non-operating power from the AC outlet with its POWER or STANDBY/ON switch not in the ON position.

• The apparatus should be located close enough to the AC outlet so that you can easily grasp the power cord plug at any time.

• The main plug is used as the disconnect device, the discon-nect device shall remain readily operable.

• If the product uses batteries (including a battery pack or installed batteries), they should not be exposed to sunshine, fire or excessive heat.

• Caution should be taken when using earphones or head-phones with the product because excessive sound pressure (volume) from earphones or head- phones can cause hearing loss.


INTRODUCTION AND FEATURES

The Demidoff Diamond Anniversary is the Diamond Line flagship amplifier featuring two chassis separated with massive power supply providing high current combined with super high efficiency design.

The Demidoff Diamond Anniversary needs two hundred hours handmade skillful work to be produced and features more than 250 mt point by point soldered wires. All meticulously selected custom parts are hand assembled and checked to offer the greatest audio experience.

The Demidoff Diamond Anniversary uses the finest implementation of the Gold Note Mir-ror-Amp™ design, which deploys a gain stage through a proprietary cascode differential amplifier. The Mirror Current design provides a superlinear, virtually distortion-free signal. The power supply takes advantage of a discrete massive chassis and is made up of eighteen handcrafted massive trans-formers specifically manufactured to strict specification to ensure the highest quality in every single stage of the amp. The power supply features a proprietary inductive design providing a virtual battery effect and extremely low AC interferences.

The strategic audio signal paths are wired with twisted pure Silver bars. The audio amplifier is set in a totally separated unit wired using two professional Neutrik connectors keeping the source of all the power supply conveniently far to achieve the best audio performance.

The Double Mono Active Volume Control system of the Diamond Anniversary is developed using a Texas Instruments PGA2310 device that provides, through strict tolerance resistors, a step-by-step single channel volume control for high-end audio resolution, lowest distortion and perfect channel balance. The active preamp stage allows a 10dB gain for best resolution and perfect unit control. The volume control is stepped with 0.5dB high precision 0.1% resistors. Due to the Double Mono setup the active Volume Control features also a sonically ideal balance control solution. Being a fully remote controlled unit it also features a display to control the volume and input selection setup.

The Demidoff Diamond Anniversary does not have any active or passive filters on the audio signal path to preserve best audio performance. Thermal switches to cut power off in the event overheating condition solely control the unit. This Decade Edition of the Demidoff Diamond Anniversary amplifier only uses the finest electronic components and represents the absolute state of the art for 21st Century electronics design.

POSITIONING OF THE UNIT

Gold Note Demidoff Diamond Anniversary has been designed for use in Hi-Fi systems in sheltered locations. It ought therefore to be protected from any eventual variations in temperature and humidity. Avoid using in the vicinity of radiators or other strong heat sources, electrical and electronic motors, mobile phones etc.

The location in proximity of other audio components is not theoretically critical, but you should nevertheless pay attention to that. If it should have to be moved after the installation, certain readjustments may need to be made. In any case, always switch OFF and detach the AC power chord of the Gold Note Demidoff amplifier every time you need to move it.

SYMPTOM DESCRIPTION CAUSE REMEDY

SPEAKER HUMMING PROBLEMS

SWITCHING ON/OFF BUMP

THE UNIT DOES NOT WORK WHEN THE STAGE IS SWITCHED ON

• The unit is not correctly wired to the Ground

The unit bumps any time is switched ON or OFF

The speakers hum when the amplifier is connected to the system

• It is important to notice that it does not produce any risk even if the bump is high

• The AC Stage plug is discon-nected from the AC wall plug

• One of the fuses is blown

• Turn Off the amplifier as first but turn it on as last of the audio system unit

• Connect it securely being sure that the AC wall plug works correctly.

• Connect them properly

• Substitute the fuse exclusively with one of the same value

• The interconnect cables are not properly connected to the amp.

• The interconnect input and/or output cables are not shielded.

• Be sure your area and personal environment are well grounded eventually isolate the ground Pin of the power chord plug for verification.

• Be sure to always use shielded cables for the amp connections.
