Interdyn has a full selection of Amplifiers to suit all Quality, Power, Control and Budget requirements, so you can rest assured you have the right product to suit any room.


So, what amp works where?




Single Zone

Designed for the music lover. This list of 2 channel amplifiers are the perfect choice for a single zone of music. This could be a lounge room, bedroom or a music room. Somewhere you might like to listen to your turntable, CD player or stream music. The perfect solution for these rooms could be:


RB-1552 MkII - 2 Channel Power Amplifier

RB-1552 Mk II is built upon the same platform as the RB-1582 MkII with only a slightly smaller power output capability at 2 x 130 Watts.



The RB-1552 MkII is engineered to be powerful and robust, yet able to extract every last nuance out of even the most complex musical score.


Notable features of the amplifier include independent left and right power rectification stages and decoupling. The layout is essentially a mono block design. Further evidence of design over-spec is in the selection of premium “slit-foil” capacitors, which provide plenty of reserve energy for extremely dynamic audio passages and are able to quickly replenish themselves due to the nature of their unique design. Input options are balanced XLR or unbalanced RCA connectors.


The RB-1552 MkII stereo amplifier has been engineered to provide high-resolution audio performance, yet it is very affordable, as has been the tradition with Rotel electronics for over 50 years.

At 2 x 200 watts per channel and utilising Rotel's Balanced Design Concept for superior performance, the RB-1582 MkII is a compelling stereo amplifier, providing the massive current necessary to drive the very largest Hi-Fi systems effortlessly.



Like its smaller brother, the RB-1582 MkII has been designed to excel at resolving the subtle details in music as well as supplying the brawn required for extremely dynamic passages. It is able to achieve this difficult dual requirement because of the meticulous attention paid to circuit design and parts selection.

The RB-1582 MkII's high-end performance begins with an extremely large toroidal transformer combined with a total of 60,000µF storage capacity in special “slit foil” capacitors to provide completely stable power to the output stage. Slit foil capacitors have the ability to charge and discharge extremely quickly, thereby ensuring signal fidelity during orchestral crescendos or repetitive kick-drum impacts, for example. Both left and right channel construction are laid out in a mono block design (after the toroidal transformer) and all grounding is terminated in a star pattern on a copper grounding plate to ensure low signal to noise. The output stage is a discrete design that consists of 10 high current bipolar transistors per channel. Input options consist of both balanced XLR and unbalanced RCA connectors.

The RB-1582 MkII stereo power amplifier is yet another outstanding example of Rotel’s Balanced Design Concept and will form the heart of a very impressive stereo or home theatre system for years to come.
