[. . . ] Do not open the top or bottom covers of the unit. Do not install the unit in a spot exposed to direct sunlight or excessive heat or humidity. Also avoid places with too much dust or the possibility of water splashing. When replacing a fuse, only use a new one with the prescribed rating. [. . . ] There is a Protection function installed in the unit to protect the unit and speakers from various problems. When Protection operates, the indicator informs you of the condition. Part name Self-tapping screws (ø4 × 16 mm) Terminal cover (Power terminal) Speaker level input cable External Number of View Items 4 1 1 The rated input power of the speakers that are going to be connected should be greater than the maximum output power (in Watts) of the amplifier. Use of speakers having input power ratings that are less than the output power of the amplifier will cause smoke to be emitted as well as damage. The impedance of the speakers that are going to be connected should be 2 or greater (for stereo connections), or 4 or greater (for bridged connections). When more than one set of speakers are going to be used, calculate the combined impedance of the speakers and then connect suitable speakers to the amplifier. This switch allow filtering of the speaker output signals. Only frequencies of 80 Hz or lower are output. Be sure to connect it with all the systems. Set this control according to the pre-output level of the center unit connected with this unit, or to the maximum power output of the genuineaccessory car stereo. use the diagram on the right as a guide. NOTE For the pre-output level or the maximum power output, refer to the <Specifications> in the instruction manual of the center unit. When you wish to use the unit as a stereo amplifier, stereo connections are used. the speakers to be connected should have an impedance of 2 or greater. When multiple speakers are to be connected, ensure that the combined impedance is 2 or greater for each channel. When you wish to use the unit as a highoutput monaural amplifier, bridged connections are used. When multiple speakers are to be connected, ensure that the combined impedance is 4 or greater. 2CAUTION The rated input of the speakers should be no less than the maximum output of the amplifier. The genuine-accessory car stereo shall have a maximum power output of no more than 40 W. Do not connect the speaker output leads from a power amplifier (Optional) to the speaker level input terminals of this unit, for this may cause malfunction or damage. Do not connect cables and leads to both RCA cable input jacks and the speaker level input terminals simultaneously, for this may cause malfunction or damage. Connect the power control lead to a power supply which can be turned ON/OFF by the ignition key switch (ACC line).
