Manufacturer's warranty period: 3 years
This product has been tested and found to comply with the limits for a Class A digital audio device.
The McIntosh MR87 is an AM/FM stereo tuner designed to deliver the best sound quality, featuring a newly developed FM receiver circuit, XLR balanced output terminals, and a power supply with a large-capacity, low-leakage R-core transformer. It is equipped with a high-performance A/D conversion circuit that converts received analog broadcasts into digital signals, which can be output via S/PDIF coaxial or optical terminals. In addition, although it is a PLL synthesizer type tuner, it is equipped with a dial pointer display mechanism linked to a knob with a large flywheel so that you can select stations with the analog feel you are used to.
