Rotel RC-1572 MKII Stereo Pre Amplifier & Rotel RB-1552MKII Stereo Power Amplifier - Black
Rotel RC-1572 MKII Stereo Pre Amplifier
As an essential component in a Hi-Fi audio stack the RC-1572MKII’s precision engineering begins with Rotel’s ultra-low noise power supply including a large, in-house manufactured toroidal transformer. The transformer design reduces stray radiated emissions and feeds a bank of slit-foil, low ESR capacitors delivering stable current to all sensitive circuits reducing noise and distortion with an ultra-quiet noise floor.
A premium Texas Instruments 32-bit Digital to Analog converter (DAC) renders the digital sources supported by custom tuned, proprietary external output filters ensuring the audio is effortlessly presented with exceptional dynamic detail and musical expression.
Analog, Digital, XLR, aptXTM and AAC Wireless Bluetooth and Moving Magnet Phono Stage inputs ensure connection to your favorite music sources. Digital media files are supported via a 32-bit/384kHz PC-USB connection supporting MQA and is fully certified Roon Tested for graceful access to the near limitless catalog of online music.
Rotel RB-1552MKII Stereo Power Amplifier
The RB-1552MKII is a 120 watt per channel class A/B amplifier. It is engineered to be powerful and robust, yet able to extract every last nuance out of even the most complex musical score.
Rotel engineering’s fanatical attention to detail means the sum is greater than the parts, what we call our Balanced Design Concept*. Each aspect of design is carefully considered holistically to result in maximum audio performance; from the selection of an over-sized power supply featuring a highly efficient, low magnetic field toroidal transformer to multiple, high-current bipolar output transistors. Circuit topology is planned, implemented, evaluated, and adjusted to achieve optimum results. The RB-1552MKII features independent left and right power rectification stages and decoupling, and 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.
