User manual SONY TA-N55ES

[. . . ] This chapter describes how to connect a Sony TA-E9000ES control amplifier, your speakers, and your other audio components to the power amplifier. Check that you received the following items: · Before you get started ⷠTurn off the power to all components before making any connections. ⷠDo not connect the AC power cords until all of the connections are completed. ⷠBe sure to make connections firmly to avoid hum and noise. [. . . ] ⷠTo obtain a higher power output when using speakers with a nominal impedance greater than 8 ohms, connect the speakers using BTL connections. Set the SPEAKER IMPEDANCE selector on the rear panel according to the type of speakers you are connecting. When making normal (non-BTL) connections to your speakers, be sure the OPERATION selector on the rear panel of the power amplifier is set to "NORMAL". If you have a separate two channel (stereo) amplifier that you would also like to use with the front speakers, connect it to the EXTRA 2 CH INPUT jacks. Use one power amplifier for the front and center speakers, and one for the rear speakers. Make the following connections if you would like to use your integrated stereo amplifier to power the front speakers and this unit to power the rear and center speakers. Set the volume control on your integrated stereo amplifier to the center position (roughly 12 o'clock). Using the Power Amplifier with a Digital Signal Processor If necessary, you can use more than one power amplifier. Make the following connections if you need more power than provided by the normal connections. Use one power amplifier for the front and center speakers, and one for the rear speakers. When making BTL connections as shown in this illustration, the gain level on the TA-N55ES center speaker output drops about 6 dB compared to the output of the other speakers. * When OPERATION is in this position and a center speaker is connected, the center speaker gain level drops about 6 dB. When this happens, raise the level of the center speaker on the AV control amplifier (TA-E9000ES, etc. Should any solid object or liquid fall into the cabinet, unplug the power amplifier and have it checked by qualified personnel before operating it any further. Before operating the power amplifier, check that the operating voltage is identical with your local power supply. If you are not going to use the power amplifier for a long time, be sure to disconnect the power amplifier from the wall outlet. To disconnect the AC power cord, grasp the plug itself; never pull the cord. ⷠAC power cord must be changed only at the qualified service shop. Place the power amplifier in a location with adequate ventilation to prevent heat buildup and prolong the life of the power amplifier. ⷠDo not place the power amplifier near heat sources, or in a place subject to direct sunlight, excessive dust or mechanical shock. ⷠDo not place anything on top of the cabinet that might block the ventilation holes and cause malfunctions. ⷠDo not place the power amplifier: ­ Any place that is not level or unstable. [. . . ] / The protective device on the power amplifier has been activated because of a short circuit. Turn off the power amplifier, eliminate the short-circuit problem and turn on the power again. / Check that the speakers and components are connected correctly and securely. / Make sure all connections are made with the correct polarity (+ and ­).
