INTRODUCTION Thank you for purchasing the Marantz MA6100 power amplifier for your sound system. Please take a few minutes to read this manual thoroughly, before you attempt connections and operation. The Marantz MA6100 is a monophonic (single channel) amplifier, that is designed for home theater and high quality audio systems. 3. NAMES AND FUNCTIONS MONO POWER AMPLIFIER MA6100 ENGLISH 2. FEATURES · The MA6100 is a monaural power amplifier developed for use in hi-fi AV systems. · It is a high-power power amplifier with all-discrete circuit configuration with rated outputs of 125 W/8-ohms. · It is designed with narrow panel area to reduce the installation area. The width becomes 17-3/8 inches (440 mm) when 5 units are placed side by side. · The small space requirement is ideal for use as an extension amplifier for AV components such as a Dolby Digital Surround processor. · It is provided with the MARANTZ remote control capability so its power can be controlled from a MARANTZ preamplifier or integrated amplifier (MARANTZ remote control compatible products). · The power of the unit can be switched by remote control using a video signal or DC signal.

AC OUTLET 120V 60HZ UNSWITCHED 200W MAX SPEAKER SYSTEM 8 OHMS 4 Nq POWER switch Press the button to turn power on (POWER ON mode), and press it again to turn power off (POWER OFF mode). When it is required to remote control the power mode of the MA6100, be sure to leave this switch in the POWER ON mode. i SPEAKER SYSTEM terminals Connect with speakers using speaker cords. Respect the + and - polarity when connecting speakers. Use speakers with an impedance of 8 to 16 ohms. Nw POWER ON/STANDBY indicator A POWER ON/ STANDBY indicator, the indicator glow red when the unit is in Standby mode and blue when the unit is On. o AC OUTLET ENGLISH This receptacle supplies AC power regardless of the power switch setting. The total power consumption of the equipment connected to this receptacle should not exceed 200 W. If you want to connect the MA6100, you can connect only one unit here. Do not connect more than one MA6100 in series. e Audio INPUT jack Connect the preamplifier output to this jack. !0 Power cord r Audio INVERT OUTPUT jack This jack is for output of signal which was inverted from the normal input signal. Insert the plug at the extremity of the power cord into a 120 V AC household AC outlet. To Enjoy sound with a higher quality, it is recommended to match the power connection polarity with other components. The white-lined wire of the power cord is the neutral (GND) wire. t REMOTE CONT. IN jack Connect with the remote control output jack of a component which is compatible with MARANTZ remote control system. The remote control allows to switch the power of the MA6100 between the "POWER ON" mode and "STANDBY" mode. y REMOTE CONT. OUT jack Connect with the remote control input jack of a component which is compatible with MARANTZ remote control system. u EXT. CONT IN jack Not connected when the power is to be controlled from a MARANTZ remote control unit. Connect to the video signal output of a video component when the power is to be controlled based on a video signal. The external control allows to switch the "POWER ON" and "STANDBY" modes of the unit according to the "presence" and "absence" of video signal. When the video signal becomes absent while the power of the unit is on, it enters the "STANDBY" mode in about 4 seconds; the unit enters the "POWER ON" mode again when the video signal is input again. As the control data of the EXT. CONT IN jack is also output at the REMOTE CONT. OUT jack, the MA6100 units connected after this unit can also be switched between the "POWER ON" and "STANDBY" modes. Leave Power switch q in the ON position. * External control using a signal from 5 to 13 V in place of video signal is also possible using this jack. However, as this scheme belongs to the professional use, please consult MARANTZ if you want to adopt such an external control scheme. 5 4.
