Rotel RB-1552 MKII 2-Channel Power Amplifier

The Rotel RB-1552 MKII is a stereo power amplifier in class AB offering 130 W per channel at 8 ohms, with power reaching up to 185 W at 4 ohms. In line with Rotel’s philosophy for over 50 years, the RB-1552 MKII combines refined sound quality with an affordable price.

Sleek Design and Robust Construction

The RB-1552 MKII features an elegant brushed aluminum silver front panel. Its solid chassis and generous dimensions (W 43.1 x D 33.9 x H 14.4 cm, weighing 12.4 kg) reflect serious construction, ensuring lasting performance. Gold-plated balanced XLR and unbalanced RCA input connectors ensure optimal signal transmission. Four speaker terminals allow for connecting two pairs of speakers simultaneously.

Oversized Power Supply for Stunning Dynamics

At the heart of the RB-1552 MKII is an oversized power supply, built around a low-radiation, high-efficiency toroidal transformer. British-made “slit-foil” capacitors store abundant energy reserves to effortlessly handle the most demanding passages. This generous power supply gives the amplifier exceptional dynamics and the ability to easily drive challenging speakers.

Sophisticated Electronics for Ultra-Precise Sound Reproduction

The power stages of the RB-1552 MKII utilize multiple high-current bipolar transistors. Each channel, completely separate from the other, benefits from its own rectification and filtering circuit. This dual mono configuration ensures perfect channel separation and a very wide soundstage. All critical components are hand-sorted and matched for optimal precision. The result is sound with remarkable transparency and musicality, with an astonishing level of detail.

Impressive Technical Specifications

With a frequency response ranging from 10 Hz to 100 kHz (+/- 0.5 dB), the RB-1552 MKII reproduces the entire audio spectrum without any alteration. Its harmonic distortion rate of less than 0.03% from 20 Hz to 20 kHz at 8 Ω reflects exemplary linearity. The signal-to-noise ratio of 120 dB (A-weighted) ensures absolute operational silence, highlighting micro-details. Finally, the high damping factor (450) ensures perfect control of speaker diaphragms for deep and tight bass.

Effective Protection for Unmatched Peace of Mind

To guard against any risk of damage under abnormal conditions, the RB-1552 MKII incorporates highly sophisticated thermal and overload protection circuits. Unlike many competing devices, these safety features do not affect sound performance. They continuously monitor the temperature of power components and the current passing through them, cutting off power if limits are exceeded. A front panel indicator signals the possible activation of this protection.

A Versatile Amplifier That Adapts to Your Setup

Thanks to its 12V trigger input and output, the RB-1552 MKII can be powered on/off by another device or control others. This feature facilitates its integration into a complete audio-video system. Additionally, the included rack mounting accessories allow for easy installation of this amplifier in a standard cabinet. With the RB-1552 MKII, Rotel delivers an amplifier equally suited for 2-channel hi-fi setups and the most ambitious home theater systems.

What are the main advantages of the RB-1552 MKII compared to a regular amplifier?

The RB-1552 MKII stands out with its ultra-robust construction, generous power supply, handpicked components, and dual mono design. These elements provide it with stunning dynamics, high precision, a very wide soundstage, and exceptional detail. Its ability to easily drive challenging loads is also a major asset.

Can I connect two pairs of speakers to this amplifier?

Yes, the RB-1552 MKII has two pairs of speaker terminals per channel. You can connect a total of four speakers. Note that there is no selector for choosing speakers, so both pairs will operate simultaneously.

Is there a risk of this amplifier damaging my speakers in case of a problem?

This is very unlikely. The RB-1552 MKII incorporates sophisticated thermal and overload protection circuits. In case of an anomaly (short circuit, overheating…), the amplifier will go into protection mode by cutting the sound. An indicator on the front panel will alert you to this situation.

What cables should I use to get the best out of the RB-1552 MKII?

Given the very high performance level of this amplifier, it is recommended to use high-quality interconnect and speaker cables. Opt for balanced connections (XLR) with quality shielded cables. For speakers, choose OFC copper cables with a large cross-section (at least 2.5 mm²).

What is the difference between the RB-1552 MKII and the RB-1582 MKII?

The RB-1582 MKII is the big brother of the RB-1552 MKII. It uses the same platform but delivers a higher output power of 200 W per channel at 8 ohms, compared to 130 W for the RB-1552 MKII. It is therefore better suited for the most challenging speakers to drive.

5/5 stars

The Rotel RB-1552 MkII is the quiet star of my system.

It sits between my FiiO K15 and my Klipsch RF-7, and that is exactly where it should be. It simply takes the balanced signal from the K15 and delivers clean Class AB power, exactly as I want to hear it. It does not try to impress by adding warmth, extra detail, or a particular sound signature. On the contrary, it completely gets out of the way to let the source and speakers do what they do best.

The Klipsch RF-7 are very sensitive speakers, so they do not need huge power. What they benefit from is an amplifier that is quiet, controlled, and seemingly effortless. The RB-1552 MkII fulfills this role perfectly. It has more than enough power in reserve, excellent speaker control, and a natural rather than forced presentation.

What I appreciate most is that I never have to think about the amplifier when listening to music. My attention remains entirely focused on the sound. To me, that is the hallmark of excellent design.

If you are looking for an amplifier that amplifies faithfully without unnecessary coloration, the Rotel RB-1552 MkII deserves your full attention. In my system, it has proven to be an ideal partner for the FiiO K15 and the Klipsch RF-7.

5/5 étoiles

Le Rotel RB-1552 MkII est la star silencieuse de mon système.

Il se place entre mon FiiO K15 et mes Klipsch RF-7, et c’est exactement là qu’il doit être. Il se contente de prendre le signal symétrique du K15 et de délivrer une puissance propre en classe AB, telle que je souhaite l’entendre. Il n’essaie pas d’impressionner en ajoutant de la chaleur, des détails supplémentaires ou une signature sonore particulière. Au contraire, il s’efface complètement pour laisser la source et les enceintes faire ce qu’elles font de mieux.

Les Klipsch RF-7 sont des enceintes très sensibles, elles n’ont donc pas besoin d’une puissance énorme. Ce dont elles bénéficient, c’est d’un amplificateur silencieux, maîtrisé et sans effort apparent. Le RB-1552 MkII remplit parfaitement ce rôle. Il dispose d’une réserve de puissance largement suffisante, d’un excellent contrôle des enceintes et d’une restitution naturelle plutôt que forcée.

Ce que j’apprécie le plus, c’est que je n’ai jamais à penser à l’amplificateur lorsque j’écoute de la musique. Mon attention reste entièrement focalisée sur le son. Pour moi, c’est la marque d’une excellente conception.

Si vous recherchez un amplificateur qui amplifie fidèlement sans coloration inutile, le Rotel RB-1552 MkII mérite toute votre attention. Dans mon système, il s’est révélé être un partenaire idéal pour le FiiO K15 et les Klipsch RF-7.

Meeting my expectations, the KEF R3 speakers are delighted to handle power, offering beautiful mids and bass that make it possible to enjoy dub music with bookshelf speakers without a subwoofer. Note: the amplifier comes with the trigger function enabled. If you’re not using it, disable it (switch located at the back of the amplifier), otherwise, you won’t get any sound.

Conformes à mes attentes, les KEF R3 sont ravies d'avoir de la puissance, avec un beau médium et des basses qui permettent d'écouter du dub avec des enceintes bibliothèques sans subwoofer. Attention : l'ampli est livré avec la fonction trigger activée. Si vous ne l'utilisez pas, désactivez-la (interrupteur à l'arrière de l'ampli), sinon vous n'aurez pas de son.
