Linear PCM (LPCM)/Pulse code modulation This stands for linear pulse code modulation, which is the signal recording system used for music CDs and DVDs. m3u Playlists created using the WINAMP software have a playlist file extension (.m3u). MP3 MP3 is short for MPEG Audio Layer 3. It is an audio compression standard set by a working group (MPEG) of the ISO (International Standards Organization). MP3 is able to compress audio data to about 1/10th the level of a conventional disc. MS ADPCM This stands for Microsoft adaptive differential pulse code modulation, which is the signal recording system used for the multimedia software of Microsoft Corporation. Multi-session Multi-session is a recording method that allows additional data to be recorded later. When recording data on a CD-ROM, CD-R or CD-RW, etc., all data from beginning to end is treated as a single unit or session. Multi-session is a method of recording more than 2 sessions on one disc. Number of quantization bits The number of quantization bits is one factor in the overall sound quality; the higher the bit-depth, the better the sound quality. However, increasing the bit-depth also increases the amount of data and therefore storage space required.
Packet write This is a general term for a method of writing on CD-R, etc., at the time required for a file, just as is done with files on floppy or hard discs. VBR VBR is short for variable bit rate. Generally speaking CBR (constant bit rate) is more widely used. But by flexibly adjusting the bit rate according to the needs of audio compression, it is possible to achieve compressionpriority sound quality. WAV WAV is short for waveform. It is a standard audio file format for Windows. WMA WMA is short for Windows Media" Audio and refers to an audio compression technology that is developed by Microsoft Corporation. WMA data can be encoded by using Windows Media Player version 7 or later. Windows Media and the Windows logo are trademarks or registered trademarks of Microsoft Corporation in the United States and/or other countries.

Installation
Before making a final installation of the unit, temporarily connect the wiring to confirm that the connections are correct and the system works properly. Use only the parts included with the unit to ensure proper installation. The use of unauthorized parts can cause malfunctions. Consult with your nearest dealer if installation requires the drilling of holes or other modifications of the vehicle. Install the unit where it does not get in the drivers way and cannot injure the passenger if there is a sudden stop, like an emergency stop. The semiconductor laser will be damaged if it overheats, so dont install the unit anywhere hot for instance, near a heater outlet. If installation angle exceeds 60 from horizontal, the unit might not give its optimum performance. (Fig. 1) When installing, to ensure proper heat dispersal when using this unit, make sure you leave ample space behind the rear panel and wrap any loose cables so they are not blocking the vents

Connecting the Units

This unit is for vehicles with a 12-volt battery and negative grounding. Before installing it in a recreational vehicle, truck, or bus, check the battery voltage. To avoid shorts in the electrical system, be sure to disconnect the battery cable before beginning installation. Refer to the owners manual for details on connecting the power amp and other units, then make connections correctly. Secure the wiring with cable clamps or adhesive tape. To protect the wiring, wrap adhesive tape around them where they lie against metal parts. Route and secure all wiring so it cannot touch any moving parts, such as the gear shift, handbrake and seat rails. Do not route wiring in places that get hot, such as near the heater outlet. If the insulation of the wiring melts or gets torn, there is a danger of the wiring short-circuiting to the vehicle body. Dont pass the yellow lead through a hole into the engine compartment to connect to the battery. This will damage the lead insulation and cause a very dangerous short. Do not shorten any leads. If you do, the protection circuit may fail to work when it should. Never feed power to other equipment by cutting the insulation of the power supply lead of the unit and tapping into the lead. The current capacity of the lead will be exceeded, causing overheating. When replacing the fuse, be sure to use only fuse of the rating prescribed on this unit. Since a unique BPTL circuit is employed, never wire so the speaker leads are directly grounded or the left and right speaker leads are common. Speakers connected to this unit must be highpower types with minimum rating of 50 W and impedance of 4 to 8 ohms. Connecting speakers with output and/or impedance values other than those noted here may result in the speakers catching fire, emitting smoke, or becoming damaged. When this products source is switched ON, a control signal is output through the blue/white lead. Connect to an external power amps system remote control or the cars Auto-antenna relay control terminal (max. 300 mA 12 V DC). If the car features a glass antenna, connect to the antenna booster power supply terminal. When an external power amp is being used with this system, be sure not to connect the blue/white lead to the amps power terminal. Likewise, do not connect the blue/white lead to the power terminal of the auto-antenna. Such connection could cause excessive current drain and malfunction. To avoid a short-circuit, cover the disconnected lead with insulating tape. Insulate the unused speaker leads without fail. There is a possibility of a short-circuit if the leads are not insulated. To prevent incorrect connection, the input side of the IP-BUS connector is blue, and the output side is black. Connect the connectors of the same colors correctly. If this unit is installed in a vehicle that does not have an ACC (accessory) position on the ignition switch, the red lead of the unit should be connected to a terminal coupled with ignition switch ON/OFF operations. If this is not done, the vehicle battery may be drained when you are away from the vehicle for several hours.
