It is advisable when leaving the house, or during a thunderstorm, to disconnect the equipment from the mains supply. EQUIPMENT MAINS WORKING SETTING Your Marantz product has been prepared to comply with the household power and safety requirements that exist in your area. This product can be powered by 120 V AC only. COPYRIGHT Recording and playback of any material may require consent. For further information refer to the following: -- Copyright Act 1956 -- Dramatic and Musical Performers Act 1958 -- Performers Protection Acts 1963 and 1972 -- any subsequent statutory enactments and orders SM-17SA The SM-17SA is a power amp that can be switched between stereo and monaural operation (BTL operation). In addition, the SM-17SA is equipped with a line amp that is compatible with fast BTL amps. This capability makes an even more advanced audio system possible by allowing you to connect another power amp to your system so that you can implement biamp drive for the speaker system. ABOUT THIS USER GUIDE Refer to the Figures on the page 10 at the rear of this user guide. All references to the connections and controls that are printed in BOLD type are as they appear on the unit. 1 ENGLISH ENGLISH CONNECTIONS The connection method illustrated below is used when the SM-17SA is being used as a stereo power amp. For details on other connection methods, refer to the examples on the following page.

To AC power outlet CONNECTIONS OF AMPLIFIER Connect the output jacks of your pre amplifier to the INPUT jacks Connection of speaker systems Each of the speaker systems connected to this unit should have a impedance between 4 and 16 ohm. Connecting a speaker system with a lower impedance than 4 ohm may activate the protection circuitry during sound reproduction. The output terminals are provided with the positive ( :Red) and negative ( : White) polarity, and the input terminal of each speaker system also has the polarity ( and ). Caution: If you will be using two speaker systems, or you will be using the SM-17SA in BTL mode, use speaker systems that have an impedance of at least 8 ohm. If you connect a speaker system that has an impedance of less than 8 ohm, the SM-17SA's protective circuitry may be worked, making the amplifier incapable of normal stereo playback.

Turn clockwise to tighten. 2 ENGLISH ENGLISH EXAMPLES OF USAGE The examples shown below illustrate a Marantz PM-17SA (pre-main amp) and an SM-17SA being used in combination for bi-amp drive of a speaker system that is compatible with bi-wiring.

For example, if the for bi-wiring are shared, bi-amp connection is not possible with that speaker system. (The system will not operate correctly because the amp's protective circuits will be worked, etc. ) For details, refer to the user guide provided with the speaker system, or contact the manufacturer of the speaker system. AC OUTLETS [SWITCHED] The switched outlet is turned on and off by the main power switch. [UNSWITCHED] Use this outlet as the power supply for a component that does not need to be turned on and off by the main power switch. [. . . ] What seems to be a serious malfunction is often due to a simple operation mistake. If the trouble still persists after checking, please consult your dealer or nearest MARANTZ service agent. The amplifier does not work and the warm-up meter lamp does not light. [. . . ]
