HiFi ROSE RA180 Integrated Amplifier
About the HiFi ROSE RA180 Integrated Amplifier
Product Description
The RA180 is a state-of-the-art integrated amplifier using the latest innovative technologies. Power damping and dead times were reduced to 1/10 or less. Linearity was dramatically improved to create a near-perfect sound that transcends the boundaries between digital and analog.
New Concept Class AD Amplifier
The amplifier has developed from Class A to AB to Class D. Class AB was developed to improve the high heat generation and low efficiency of A. Class D has higher efficiency and higher output than AB, and also significantly improved S/N and THD characteristics compared to A and AB. However, the sound quality has been evaluated as inferior to A/AB due to the limitations of the digital circuit. The GaN class AD amplifier developed by HiFi ROSE has dramatically improved the problems of the existing Class D by applying innovative new materials.
Multi Output Component
The RA180 consists of two modules: one AMP module specialised for stable mid-bass and balance, and another specialised for smooth high-pitched and super tweeter areas. Each AMP module supports 200W (8Ω) and can output up to 400W per channel. When two independent modules are connected to a speaker's high and low frequencies separately, the driving force can be greatly improved without being affected by a counter electro-motive force. BTL mode combines two independent modules for rich, balanced sound.
Designed to Play Up to the Super Tweeter Realm
The human hearing range has an upper limit of 15-20 kHz. So, is there no need for higher frequencies? Temporarily high trebles extend well beyond 20 kHz, even in harmonious sound. For example, trumpets have a frequency response that extends to 100 kHz, and 88.2 kHz to 192 kHz sources have a 40 kHz to 96 kHz frequency response.
The RA180 is designed with a wide frequency response range so that even high-resolution sound sources with an output range of 20 Hz to 50 kHz, 100 kHz @ -3 dB, 200 kHz @ -6 dB. Although this playability may be outside a person's hearing range, it faithfully reproduces a wide frequency range, which contributes to expressing a deep and wide sound field with the original sound.
Balanced Power Supply
The power supply has been exclusively developed for the RA180 applies 4th generation SiC FET technology to provide high output with less heat. In addition, by using a self-developed PFC (power factor circuit), it is designed not to be affected by sudden load fluctuations.
The power supply device was developed to support a powerful damping factor of at least 200,l and the high output of 100 W is designed to produce powerful bass and soft treble.
PHONO Amplifier with Variable EQ
The purpose of the PHONO amplifier provided by the RA180 is for the recording producer to accurately reproduce the original intention. It also reproduced the original sound as it is, which is the principle of HiFi ROSE.
It is designed to respond to a variety of vinyl records with low-mid bass TURNOVER and high-frequency ROLL OFF adjustment functions.
