Features of the Marantz MM7055 :

• 5 channel power amplifier
• Porthole Display with Blue Illumination Accent
• 140W/ch (8 ohms), 170W( 6 ohms) RMS Power (20Hz-20kHz)
• RCA and balanced XLR inputs
• “Current Feedback” Amplifier Output Stage
•  Custom Sound Tuning
• Marantz Reference-Grade Filter Capacitors and High-Speed Output Transistors
• Gold Plated, High Grade Loudspeaker Terminals
• Flasher Input/DC Trigger In/Out /RC-5 Remote Control

The MM7055 power amplifier produces 140 watts of high current output from each of its five channels. This is “real world” power, too, measured across the full audio bandwidth (20 Hz – 20 kHz) at 8 ohms with 0.08% Total Harmonic Distortion. Among other attributes, this means the MM7055 is capable of long-term power delivery into low impedance speakers. A massive power supply includes a multiple-secondary EI-core transformer and over 65,000 µF of custom-designed energy storage capacity to meet the demands of today’s current-hungry loudspeaker designs.

Balanced inputs and single-ended RCA inputs are both supported, and audiophile grade, gold-plated four -way binding posts insure tight connections to your choice of speaker wire. The MM7055 includes input and output jacks for DC “trigger” pulses as well as RC-5 jacks for total remote control convenience, even with legacy Marantz products. The chassis itself is heavy gauge steel for maximum isolation from external vibration as well as electromagnetic and radio frequency interference. And chassis depth is less than 14½” so the MM7055 will fit quite nicely on a shelf, in a cabinet, or in a conventional system rack.

Power. Functionality. Dependability. And classic good looks. The MM7055 is, simply speaking, a Marantz.
