User manual NAD C270

[. . . ] Do not use this unit near water; for example, near a bath tub, washbowl, kitchen sink, laundry tub, in a wet basement or near a swimming pool. The unit should be installed so that its location or position does not interfere with its proper ventilation. For example, it should not be situated on a bed, sofa, rug or similar surface that may block the ventilation openings; or placed in a built-in installation, such as a bookcase or cabinet, that may impede the flow of air through its ventilation openings. The unit should be situated from heat sources such as radiators, heat registers, stoves or other devices (including amplifiers) that produce heat. [. . . ] When Bi-Amping with different models of power amplifiers, it is likely to occur that one power amplifier has more "gain" than the other, resulting in a mis-match in level for the woofer and tweeter of the speaker. Adjust the level control so that woofer and tweeter are in perfect balance with each other (identical gain of power amplifiers). Connect the output from a pre-amplifier or processor, such as a surround-sound decoder, to this set of inputs. Use a twin RCA-toRCA lead to connect to the left and right `Audio Output' of the preamp or processor to the Fixed-In sockets. NOTES: Always turn the C270 and other components in the system off before connecting or disconnecting anything to the "Fixed In" or Variable In" sockets. When using the "Variable In" sockets, make sure the "input Select" switch (No. INPUT LEVEL CONTROL The Input Level control works in combination with "Variable In" (No. With the control the volume to the power amplifier can be adjusted from zero (counter clock-wise) to maximum (turned up all the way clock-wise). Refer also to section "Variable In" in this chapter for more information. NOTE: Always turn the C270 and other components in the system off before connecting or disconnecting anything to the "Fixed In" or Variable In" sockets. FIXED IN The Fixed Inputs take the input signal straight to the power amplifier's circuitry. This set of inputs is normally used in a system with only one power amplifier or multiple but identical power amplifiers. Refer also to section "Variable In" in this chapter for more information. Connect the output from a pre-amplifier or processor, such as a surround-sound decoder, to this set of inputs. Use a twin RCA-toRCA lead to connect to the left and right `Audio Output' of the preamp or processor to the Fixed-In sockets. NOTES: Always turn the C270 and other components in the system off before connecting or It is disconnecting anything to the "Fixed In" or Variable In" sockets. When using the Fixed In sockets, make sure the "Input Select" switch (No. Set to "FIX" for use with "Fixed In" and to "VAR" for use with "Variable In". Refer also to section "Variable In" in this chapter for more information. Use the Speakers A connectors for the `main' speakers and use the Speakers B connectors for a second pair, for example, extension speakers located in another room. Under normal operation, connect the right speaker to the terminals market `R +' and `R-' ensuring that the `R+' is connected to the `+' terminal on your loudspeaker and the `R-' is connected to the loudspeaker's `-' terminal. connect the terminals marked `L+' and `L-' to the left speaker in the same way.

Använd en signalkabel av hög kvalitet från förförstärkarens utgångar till "VARIABLE" ingångarna på C270 TÄNK PÅ ATT se till att apparaterna är avslagna innan några anslutningar görs till "FIXED" eller "VARIABLE" ingångarna. Om du skall använda förstärkaren som vanligt ansluter du höger högtalare till terminalerna märkta "R+" och "R-" och försäkra dig om att "R+" är ansluten till högtalarens pluspol och "R-" är ansluten till högtalarens minuspol. anslut vänster högtalare till "L+" och "L-" på samma sätt.
