  3. Marantz MM7025 Stereo Power Amplifier, 2-Channel (140W x 2), Both Single-Ended RCA and Balanced XLR Inputs - Black - Front_Zoom

    Product Description

    The Marantz MM7025 2-Channel Power Amplifier features current feedback circuitry and a high-capacity power supply - the EI-core transformer and ensures distortion-free sonic reproduction of the most complex audio sources, be it dynamic musical peaks or whispered dialog. Measuring less than 14” deep from front panel to rear speaker terminals, this stereo power amp has a sophisticated and elegant industrial design. The chimney-shaped heat sink efficiently processes the heat emitted from each side of the amp and a quiet cooling fan removes the heat from the chassis, cooling the inside. A high-sensitivity temperature sensor IC is used to control the cooling fan's rotation speed to minimize noise. This unit is equipped with a remote power control function. The RCA Remote Control input is connected to the preamp and the output can be connected to other compatible Marantz components; CD player, DVD player, Tuner, etc.
