The Marantz Model 15 Solid State Stereo Power Amplifier is an instrument without precedence in performance and rugged reliability. As renowned audio authority Julian Hirsch exclaimed, "if any amplifier can be termed ''indestructible''. This is the one." two independent and identical monophonic amplifiers, each with its own power supply, are bracketed together and mounted to a handsome gold anodized front panel that matches both the Model 7T preamplifier and Model 10B tuner. Because the channels are completely isolated, you suffer no power loss, "cross-talk', or other interactions that oftentimes occur from simultaneous operation of both channels with only one power supply. The amplifiers are direct-coupled, providing instantaneous recovery from overload and full rated power throughout the full frequency range. At any audio frequency, and on any output impedance from 4 to 16 ohms, the Model 15 is lower than on any other currently available power amplifier. You can use the Model 15 with any loudspeaker on the market, from a 4 Ω acoustic suspension system to the 16 Ω electrostatic. And, a built-in fool-proof protection circuit gives instantaneous and unobtrusive protection without causing annoying program interruptions.
All of these features combine to bring you completely reliable operation - year in and year out. The performance of the marantz Model 15 establishes wholly new standards of technical excellence for amplifiers of all types.
