Can you connect speaker out to line in?
3 Answers. You can safely connect the Green (normally “Line Out”) to the Blue (normally “Line In”). The Pink (normally “Mic”) input is generally designed to handle more amplification and since line-out operates at higher levels, you would likely overdrive the signal and not be able to hear anything anyways.
What is speaker attenuation?
Attenuators are placed between the output of the amp and the speaker. They replicate the ohm load of a speaker so the amp doesn’t “know the difference”. The reduced wattage that isn’t converted to heat is then sent to the speaker.
How many speakers can amp power?
But there are other options to consider. Most external amplifiers can power more than one speaker per channel. For example, a 4 channel amplifier may be able to power up to 8 speakers. In fact, if you wire it correctly, you will be able to pull up to twice as much power out of the amp.
Is line out same as speaker out?
Line out is an unpowered line-level signal, meaning it does not contain extra power to run speakers. Speaker-out has power, and generally can adjust the volume with software, like inside windows.
How do I connect 4 speakers to a 2 channel amp?
Connect wire from the positive terminal of amplifier to positive terminal of first speaker. Now connect wire from negative terminal of first speaker to positive terminal of the second speaker. Then connect wire from negative terminal of seond speaker to negative terminal of left of the amplifier.
What is line in input for audio?
A line-in (line input) is an audio socket that is found on audio interfaces, computer sound cards, and some mixers. It’s used to connect an external audio device such as an instrument, microphone, or CD player (remember those?). Conversely, mic-in is for microphones – you connect a wired or wireless mic to a mic-in.
How do you get attenuation?
The amount of attenuation in a given network is determined by the ratio of: Output/Input. For example, if the input voltage to a circuit is 1 volt (1V) and the output voltage is 1 milli-volt (1mV) then the amount of attenuation is 1mV/1V which is equal to 0.001 or a reduction of 1,000th.
How much attenuation do I need for speaker signal to line level?
So attenuation of about 20 dB is needed to bring the signals to right level. This conversion can be done easily using 10:1 voltage divider circuit. The circuit below is a resistor voltage divider circuit which just does about 10:1 voltage attenuation.
Can a speaker be connected to a line level?
Sometimes it is necessary to connect a device which has only speaker outputs to external amplifier’s line level inputs. Because speaker levels are much higher than line level signals, the direct connection does not usually give satisfactory results.
How much power does a speaker level circuit need?
The circuit is connected to the speaker output of the amplifier and can be used in parallel with the existing speakers. Speaker level signals are usually in 3..20V range (amplifiers up to 50W output power).
Do you need transformer to convert speaker level to line level?
So IF you were pushing a 2W peak level into that speaker, a 1:1 transformer on the old speaker wire is likely about right to interface with a line input. You don’t strictly need the transformer, but it’s a good idea in order to isolate the grounds of the two systems, and the output will now be balanced.
