HiFi Rose RA180
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. Enjoy the pure sound of nature provided by the RA180.
New Generation Class AD Amplifier
A true revolution in the world of amplification, Rose HiFi unveils an innovative Class AD architecture taking advantage of both the benefits of Class A/AB amplifiers and Class D structures. This particular design allows for improved linearity, in particular through the use of a new material, GaN (Gallium Nitride).
Furthermore, the RA180 opens the doors to bi-amplification by integrating four independent amplifier modules. Each module supports a response up to 100kHz, allowing the use of super tweeter.
To power these modules, the RA180 features a massive power stage capable of delivering 1100W of power to meet the needs of the most demanding audio systems.
Four new mono amplifier modules
The RA180 offers a stereo output and provides two channels for each right and left output. Each amplifier offers a power of 200W under 4Ω and 8Ω, allowing a bi-amplification integration, in order to feed separately the different channels of your speakers and offer a more natural and musical restitution. It is also possible to activate the BTL mode to reach a power of 2x400W.
Tone control
The RA180 offers a linear reproduction for the most faithful reproduction of the original signal. However, it offers a tone control that allows you to adjust the bass (100Hz) and treble (10kHz) levels over an adjustable range of ±15dB. This makes it possible to adapt the output of the amplifier to your audio system and your listening preferences. The tone control circuit is equipped with a high fidelity active equalizer (type AOP: 12dB slope) rather than a passive system (type CR: 6dB slope).
