SPEAKER 81 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,
l
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
l
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.
l
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. (See Fig. 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.
Make the other electrical connections. (See previous page.)
