To prevent this, connect one end of a low-capacitance shielded wire to the amplifier's ground screw (on the rear panel). [. . . ] It contains a range of installation suggestions as well as instructions to ensure safe usage. Installed properly, you can expect years of trouble-free service from this product. Input connections These amplifiers accept a broad range of input sources, including Compact Disc (CD) players; DVD, Cassette, Reelto-Reel or other tape players; Radio Tuners; Equalizers; Signal Processors. FEATURES AND CONTROLS Channel 1 and Channel 2 Power LED Display Indicate the output signal level for each channel.

Usually positive terminals are red or have a plus symbol (+), and negative terminals are black or have a minus symbol (-). Connect the speaker wires to the amplifier's left and right speaker terminals according to the terminal color polarity. Power On/Off Connecting an equalizer or external signal processor Connect the processor's OUT to the amplifier's INPUT connectors. EQ OR MIXER Channel 1 and Channel 2 Output Level Controls Lets you adjust the sound levels for each channel. Protection Circuit and Indicator The indicator will be illuminated when the amplifier is powered on and at turnon delay status; the indicator will be turned off after internal outputs are connected. The indicator will also be illuminated when the amplifier has abnormal problems, such as overload or excessive heat. STEREO OPERATION SWITCH IN "STEREO" POSITION Fan Cooling Cooling system is automatically activated whenever amplifier is turned on. This forced air cooling system rapidly exhausts interior heat, reducing operating temperature and aiding performance. REAR PANEL, XPA-240. XPA-360.
