User manual BLAUPUNKT COLORADO CM 168

[. . . ] We recommend making and testing all electrical connections before installing the receiver. Connect the leads (wires) according to instructions below. Don't assume that a seemingly-matching wire harness in the vehicle matches the receiver's wire harness wire-for-wire. Your Blaupunkt dealer may be able to sell you adapter harnesses for your vehicle, which can make connections much easier. [. . . ] (See below. ) GB 2 SPEAKER & AMPLIFIER CONNECTIONS The receiver's Dual-Level Fader allows you to fade between the front and the rear channels using the receiver's internally-amplified output via front and/or rear speaker leads AND/OR its 4-channel preamp output, providing tremendous flexibility in configuring your audio system arrangement: · You can connect a speaker (regular, co-axial or tri-axial speakers or component speaker system, all hereafter referred to simply as "speaker") to each of the receivers' four pairs of speaker leads. · With the Blaupunkt preamp output adapter 7 607 893 093 (available separately), you can provide 4-channel preamp output to additional external amplifiers and power multiple speakers or speaker systems through those amplifiers. (Blaupunkt amplifiers and speakers available separately). · You can use either or both of these two methods. 10A F RR R R LF L Fig. 6 + + + + - LR RR LF RF Connecting Speakers to the Outputs from the Receiver's Internal Amplifier To prevent short circuits or serious damage to the receiver and/or speakers: · · · · · · · · · · · · Disconnect the vehicle battery's negative terminal before making connections. Connect the speaker leads only as indicated on the speaker wire block. 6) Only use speakers that have impedance ratings of 4 ohms or higher and have power-handling capabilities greater than the receiver's stated power level. The receiver's internal amplifier is designed to handle a 4-ohm load on each pair of speaker leads. DON'T connect two speakers to a single pair of speaker leads ("in parallel") unless both speakers each have at least 8 ohms impedance. DON'T connect the left and right speaker leads to each other or to the same speakers. DON'T connect the front and rear speaker leads to each other or to the same speakers. DON'T connect the negative speaker leads to each other. DON'T connect the positive speaker leads to each other. DON'T connect any active speakers (with built-in amplifiers) to the speaker leads unless their owner's manuals specifically state that this is O. K. Cover the ends of any unused leads with electrical tape. This will prevent them from touching the vehicle or each other and causing a short-circuit and damage to the receiver or vehicle. (See previous page. ) GB 3 Connecting Additional Amplifiers or an Equalizer to the Receiver's Preamp Output Obtain the Blaupunkt RCA 4-channel preamp output adapter 7 607 893 093 from your dealer. It includes a blue/white trigger lead for switching the amplifier on and off. Connect the adapter into the top left section of the connector block on the back of the receiver. 7) Follow the amplifier's or equalizer's instructions regarding connection. [. . . ] 3) Note: Handles that have snapped into place can only be removed after you have pulled the receiver out of the complement. Remember where you store the "release handles". 8 601 910 002 1 2 1 2 Fig. 3 Fuse Replacement When replacing the fuse, be sure to use one with the correct amperage, which will be stated on the fuse case. Never use a fuse that has a stated amperage exceeding the one supplied for this receiver as this could cause malfunction and serious damage to the receiver. GB 6 Cleaning the Connectors The receiver may not operate properly if the connectors between the receiver and the detachable face are contaminated with dirt. [. . . ]
