2021 Breeze Audio New Reference Marantz HDAM Circuit Bluetooth Power Amplifiers 2 * 120W AC110V/220V Optional Nobsound | Электроника

This product is available with Bluetooth and non-Bluetooth versions. The Bluetooth version is not a general Bluetooth, it is a true Bluetooth 5.0 version, Qualcomm QCC3034 accepts, PCM5102A decoded output, supports APTX-HD lossless 24BIT protocol, and has better sound quality than direct output from mobile phones too much. It is very simple to use, the mobile phone can receive the blue signal when the Bluetooth receiver is turned on, and the analog signal of other audio will be connected when it is turned off.parameter•Dynamic range: ≥93dB, distortion rate 0.0008%• Frequency response: 10Hz-45kHz +/-3dB• Impedance: 2-8 ohms• Rated power: 80W (4-8 ohms) 100W (2-4 ohms)• Voltage: AC110V/220V2 solid aluminum alloy knobs, the left is the sound source input switch knob, the right is the volume control knob

overall arrangement

This is the famous brand new ON Semiconductor King MJ15024 10525 250W power consumption, 16A high current output, super Toshiba and Sanken. The low frequency dive is very good.

Japanese ELNA-AUDIO audio special capacitors, the sound is sweet and natural, and the analytical power is very good.

This is the core circuit of HDAM, Marantz's classic, the FET whose input stage is close to the characteristics of an electronic tube, is round, loose, delicate and charming, and full of air.

Japan Omron relay protection circuit, so that the power amplifier and speakers are working at all times in a safe state

Three-way lossless relay signal switching circuit can handle multiple audio inputs at the same time.

3 channels of audio input signals and 2 channels of audio output, using pure copper crystal wiring speaker posts, no oxidation and blackening.

250W high-power oxygen-free copper toroidal transformer without breaking point, the basic energy.

Products real shot:

Audio source selection: For debugging and tuning, we use the CD player as the standard audio source for input signals, and use ordinary CD discs with good sound quality to debug. Therefore, this machine has higher requirements for the sound source. If you don't hear good results, you may want to start with the sound source to improve it. I believe it will have a good harvest. The ideal effect may not be achieved when the computer is connected as the sound source, so it is recommended to configure the sound card independently to improve the sound quality and give play to the best performance of the power amplifier. Because the earliest audio sources used CD as the audio source standard level output, sometimes the output voltage of the audio source of individual equipment is different, which causes the unit to be distorted or the sound is not good. Please check the audio source standard by yourself. Try to buy standard audio equipment to best match the power amplifier to achieve better listening requirements.Speaker selection: This unit can be used with speakers with a sensitivity of 86db or more, impedance 4-16 ohms and a power of 20------150w. Better speakers can produce good results, even if the speakers are not good. No way. The audio is a complete system, and it is not necessary to have a good link, so please consult before buying.Properly burn-in: If you want a good sound effect, you must burn-in. The power amplifier is usually ready after a week, but if it is a new speaker, it will take 200 hours to slowly become nice. Both power amplifiers and speakers need to be cooked. The new machine needs to be run-in just like a car. So don't worry about receiving the expected sound from the machine, and burn the machine first. Because the human ear also needs to adapt to the sound of a new machine. It takes patience and open-mindedness to play music, so listening to the audio can also open up people's minds and calm down. The equipment ultimately conveys the expression of the author's feelings. It is the real good power amplifier that can move you, no matter how high or low the price is. As long as the sound resonates with your feelings, that's right. This is a good amplifier! ! !
