User manual ALPINE MRV-F302

[. . . ] When connecting the MRV-F302 to the fuse box, make sure the fuse for the intended circuit of the MRV-F302 has the appropriate amperage. The MRV-F302 uses female RCA-type jacks for connection to other units (e. Due to the high power output of the MRV-F302, it is important that all connections are clean and well secured, or damage could result. When installation and connections are completed, check the followings: a) Connections are proper. [. . . ] Your Alpine dealer knows best about noise prevention measures so consult your dealer for further information. 1 , 2 RCA Input Jacks (CH3/4), (CH1/2) Connect these jacks to the line out leads on your head unit using RCA extension cables (sold separately). Be sure to observe correct channel connections; Left to Left, Right to Right, Front to Front and Rear to Rear. 3 , 4 RCA Pre-out Jacks (CH1+3) , (CH2+4) 5 , 6 Speaker Output Terminals (CH1/2) , (CH3/4) The MRV-F302 has two sets of speaker outputs. Do not use the speaker (­) terminals as a common lead between the left and right channels. A Battery Lead (Yellow) (Sold Separately) Be sure to add a 30 amp fuse as close as possible to the battery's positive (+) terminal. This fuse will protect your vehicle's electrical system in case of a short circuit. If you need to extend this lead, the wire gauge should be 8 AWG or larger. B Remote Turn-On Lead (Blue/White) (Sold Separately) Connect this lead to the remote turn-on or power antenna (positive trigger, (+) 12V only) lead of your head unit. Cautions on wire lead connections In case of using the lead (power supply cord) purchased at the market, use the hexagon screws and the hexagon wrench included as the accessory to make connection easier. Improper handling may cause troubles, so make the connections correctly by referring to the description shown below. A special care will be necessary for the connections using the hexagon screws, so we recommend you to ask the connection for your dealer. If the wire size used is unknown, ask to the shop you get the unit, service shop, Alpine Service Center, etc. ) of the wire leads by about 7 ­ 10mm (9/32" ­ 3/ 8") from the lead end to exposure the conduction leads. If length of the conduction leads with the cover removed is too short, incorrect connection may occur and this may cause operation failure or sound interruption. On the other hand, if the length is too long, an electrical short-circuit may occur. Tighten the hexagon screw with the hexagon wrench, and the lead will be fixed. 4) Before making this connection, dress a short-circuit prevention rubber tube to the leads. To prevent disconnection of the leads or drop of the unit, do not grasp the leads when carrying the unit. O , s Input Mode Selector Switch a) Set to the "ST" position (center) when the two channels are used in stereo. the CH-1 (or CH2) input will output at the Speaker Output Ter1 ST 1+2 minal CH-1 (or CH-2). B) Set to the "1" position when the two channels are used for one channel of a stereo bridged system. [. . . ] Using this connection method, the MRVF302 will turn on and stay on as long as the ignition switch is on. If this is objectionable, a SPST (Single Pole, Single Throw) switch, in addition to the 3A fuse mentioned above, may be installed in-line on the MRV-F302 turn-on lead. Therefore, the switch should be mounted so that is accessible by the driver. 1 Remote Turn-On Lead 2 Power Antenna 3 Blue/White Wire 4 To other Alpine components' Remote Turn-On Leads 5 SPST Switch (optional) 6 Fuse (3A) 7 As close as possible to the vehicle's ignition tap 8 Ignition Source 4 -Channel System/Système à 4 canaux/Sistema de 4 canales 5 Use either RCA line level or speaker level inputs.
