MARANTZ MM7055 140w 5CH POWER AMPLIFIER
The new MM7055 is the five-channel option in the extensive range of power amplifiers we offer this year.
This component is based on the technology of the MM8003 and has the same chassis. This allows it to provide each channel with a smashing 140 W rms at 8 ohms. The ultra-wide bandwidth current feedback technology handles the highest SACD frequencies with ease, making it ideal for DTS Master Audio and Dolby TrueHD HD formats. The result: complete precision in sound and image balance, speed and dynamics. In addition, there are also XLR audio inputs, DC triggers and a Marantz bus system for remote switching on and off. Finally, we have added a new display that perfectly matches the design of the AV7005. This is truly breathtaking power and convenience.
