Connecting the sound amplifier to a separateradio tape recorder, whether it's a CD player, tuner or combo-station, in principle, the process is simple. Almost every radio is equipped with RCA sockets for outputting audio signal to an external device. The amplifier, acting as a receiver, receives a signal on the audio inputs. Accordingly, the amplifier is connected to the original radio tape recorder by means of an interconnection RCA cable with the choice of a certain number of linear channels.
A small problem can arise ifthe number of output jacks of a radio tape recorder does not coincide with quantity of input sockets of the amplifier. For example, the radio has two standard stereo outputs. And the amplifier has built-in 4 receiving channels: a pair for front speakers and a pair for side speakers or one subwoofer. To repeat the incoming audio signal to all channels of the amplifier, use the input selector. Sometimes a signal is passed through several amplifiers: from the output of the first to the input of the second. Or the signal is repeated by a crossover.
What to do when there is no line output on the radio
Often there are cases when amplify the sound withthe radio tape recorder is problematic due to the lack of linear outputs. Then how to connect the receiver to the receiver? You can use several different methods. They differ in sound quality and in the cost of implementation. Let's consider connection of a radio tape recorder through high-level inputs.
The principle of connection is very common.To the amplifier through an input channel the signal from a radio tape recorder is given. Usually, if the speakers are connected to the radio, the signal, passing through the built-in micro amplifier of the player, hits the speakers. In our case, instead of outputting to the speaker, the sound must be redirected to the input of an external amplifier. In this case, the magnitude of the linear signal can reach about 10-15 W. All you need is to equip the amplifier with the appropriate high-level inputs, which will be fed with a linear source signal.
In the same way, you can consider connectingA radio to a subwoofer with the built in amplifier of a sound. It's even simpler, because each subwoofer model is equipped with one or more high-level inputs. A system cable often includes a power cable and a separate cord for signal transmission.
Connecting to an amplifier via a high inputlevel is often subjected to extensive criticism. However, the reasons for it are not so significant. Yes, there is a slight discrepancy in the sound with the original signal, but it is almost imperceptible. Especially if it's a solid quality amplifier or a subwoofer. If you only need to connect the radio to the subwoofer, then the sound will be quite acceptable.
Paradoxically, systems with high qualitysound can make some distortions due to the peculiarities of their design, which are not so noticeable in middle-class systems. In short, connecting to a high-level input has a greater advantage than a linear one. Both the price and ease of connection add up in favor of the former.
But do not think that this method does not allowget a good, more than acceptable sound. Yes, there are premium amplifiers with personal signal sources for individual expensive audio systems. But they are also equipped with high-level input jacks for compatibility.
Even if the amplifier does not have input channelshigh level, the signal can always be converted to linear. For this, converters of match size are used. Their price is quite acceptable. The choice should be reasonable and balanced. It is not worth chasing cheap converters. It is better to use products of famous manufacturers of middle or top-class.
