Energy and powerful that you can not imagine as a small and lightweight amplifier

Description

CERENATE isThe super -raw noise of the US patent is operated by the sign wave of 220kHz, and it is compact and lightweight because it is a compulsory air -cooled system that does not rotate in normal use. The second side of the transformer adopts a complete left and right independent type.

Equipped with a remote sensing terminal (BNC) for reliable speaker driving by applying feedback from the speaker side. With a high -frequency NFB in front of the output inductor at the border of 50kHz, a low -frequency NFB later, it is stable by the split feedback method that combines stability and high sound quality, and works effectively without using remote sensing. 。

The headphone output can be used as an amplifier dedicated to the headphone for almost class A unless the speaker is connected at the same time as the speaker terminal.

CERENATE uses high -quality parts. Fidelix adopts the first shot key barrier diode in the world at key points, DALE resistance, Takuman resistance, audio chemicon, copper foil polypropylene condenser, gold -plated terminals and switches, thick power cables, high rigidity foot structures, all. In addition to the transformer of the ritz line, the power line is set in two wires without ground terminals, and is set to undolute. There are no contacts for AC inlet, Hyuse holder, power supply main switch, output relay or connector.


When unusually heated, it has a double protection, short protection, and speaker protection with a double of fan rotation and muting.

By connecting the left and right balance input in parallel and connecting one to the reverse polarity, the BTL operation of the complete balance is performed, and the monaural power amplifier enables higher sound quality and high output.



The waveform above the photo below is a voltage waveform on the secondary side that is added to the switching power trance, and the lower is a voltage waveform on the primary side tap. The switching frequency is 220kHz, which is higher than 192kHz sampling used in DVD audio, and is a very beautiful waveform for switching power. For this reason, the switching noise is extremely low, and the glittering coloring of the high -frequency high frequencies that tends to be switched power is suppressed, achieving the name of SERENITY (clear, clear, peaceful, calm, calm).


Switching noise is a phenomenal value with a noise margin with a noise margin with nearly 40 dB compared to strict Cispr 13, which is an international standard specified for audio devices, so it is less than 30dB compared to general switching power supply. 。 This is the result of thoroughly eliminating the glittering and dirty habits that are common in switching power supply. Switching noise of 1MHz or more cannot be observed, and it can be said that it is the best low -noise power supply in the world. The noise countermeasures are mainly based on basic waves, double -waves, and 4x waves, and are achieved by selecting and arranging filters (two common mode chalk, two Y -capacitors, 1 X -capacitor).

100kHz response waveform. Because it is a very obedient response, it can be said that phase compensation is performed perfectly.



Because it is a completely DC amplifier, it is naturally a stunning direction waves even at 10Hz. It can be seen that the phase characteristics are as accurate over a wide frequency band.

Review

[Lightweight, compact power amplifier equipped with low noise switching power]
The wide range has no habit and has instantaneous power and has a high braking force.

Fidelix has developed an unparalleled low -no -noise switching regulator "Serinity Power Source", and has launched an AB -class DC power amplifier with a volume of 40W+40W/8Ω, which combines both small and lightweight and high sound quality.

The input terminal is an imbalance of the RCA, a complex balance connector that supports XLR and TRS, and the output terminal is equipped with a banana plug -compatible speaker terminal and headphone terminal, and only the headphones are used without connecting the speakers. It becomes a class operation.

The amb part is a power amplifier IC "LM3886", a power amplifier IC, a national semi -condactor, which is used in Jeffroland's Model10 and other high -quality sound quality.
A wide -band amplifier is built by operating this as a full DC amb that can amplified to the DC.
The output relay that tends to deteriorate the sound quality is expelled because the IC has a built -in multiple protective circuits and mute circuits and does not produce hop noise when power is turned off and off.
The rear panel is equipped with a BNC remote sensing terminal, and it is also possible to fade back the amplifier from the speaker terminal to correct the deterioration due to the speaker cable.

Serinity power supply is characterized by high instantaneous current supply capacity and super low noise, and because the AC input is electrically non -polarth, it does not have to worry about the direction of the power plug.
This unit has a good S/N feeling and transparency that does not seem to adopt a switching power supply, and the sound is high.
In addition, since there is no habit in the wide range, it has instantaneous power and the braking power, it produces so energetic and powerful sound that you can not imagine as a small and lightweight amplifier.
I was worried about the lack of power because the rated output was 40W, but it seems that there is no shortage of power even if I raise the volume with Artemis EOS with 88db efficiency, so it seems that a considerable power can be achieved instantaneously.
When the speaker was removed and used as a headphone amplifier, it was impressive with this with a very large and stretched sound. *Audio accessories
