How to make a radio connection to the subwoofer.

Connecting audio amplifier to separate the radio, whether it is CD player, tuner or a combo-station, in principle, the process is simple.Almost every cassette recorder is equipped with RCA jacks for audio output to an external device.Power, acting as the receiver receives the signal on the audio input.Accordingly, the connection of the amplifier to the standard achieved by the radio interconnect RCA cable c selecting a specific number of linear channels.

small problem can occur if the amount of output jacks recorder does not coincide with the number of input terminals of the amplifier.For example, radio has two standard outputs stereo.A built in amplifier 4 receiving channel: a pair of front speakers and a pair of surround speakers and a subwoofer.To repeat the incoming audio signal to each channel amplifier using an input selector.Sometimes, the signal is passed through several amplifiers: output from the first input to the second.Alternatively, the signal is repeated crossover.

What to do when the radio is not linear output

Often there are cases in which amplify the sound from the radio is problematic due to the lack of line outputs.Then how to implement the radio connection to the receiver?One can use several different methods.They differ in sound quality and cost of implementation.Consider a radio connection through high-level inputs.

principle of connection is very common.The amplifier is fed through the input channel signal from the radio.Normally if you are connecting speakers to the radio, the signal passes through a built-in mikrousilitel player hits the speakers.In our case, instead of to the speaker sound you want to redirect the input of an external amplifier.The magnitude of the signal line can be up to about 10-15 watts.All that is needed is to equip the relevant high-level amplifier inputs, which will be supplied to the source signal line.

Likewise, you can see the radio connection to the subwoofer with integrated amplifier sound.It is even easier, as each model is equipped with a subwoofer with one or more high-level inputs.The delivery system is often included cable and a separate AC power cord for the signal.

connection to the amplifier via the high level input is often subjected to extensive criticism.However, the reasons for it are not so essential.Yes, there is a slight difference in sound with the original signal, but it is almost imperceptible.Especially when it comes to solid quality amplifier or subwoofer.If you only need to implement the radio connection to the subwoofer, the sound is quite acceptable.

Paradoxically, a system with high quality sound can make some distortion due to the nature of their design, which are not so noticeable in the midrange.In short, the connection to the high-level input has a greater advantage than linear.And the price, and ease of connection is in favor of the former.

But do not think that this method does not provide a good, more than acceptable sound.Yes, there are amplifiers with premium personal signal sources for certain expensive audio systems.But they also come with high-level input jacks for compatibility.

Even if the amplifier input channels are no high-level signal can always be converted into linear.For this purpose the size of match converters.Their price is acceptable.The choice must be reasonable and balanced.Do not chase for cheap converters.It is best to use products known manufacturers middle or top grade.
