Do RCA cables go to input or output?
Your amplifier gets its input signals from the receiver’s output typically via RCA cables. RCA cables come in stereo pairs, in various lengths. When running new speaker wires from your amplifier’s output to the speakers, any size wire from 18- to 14-gauge will work fine.
What is stereo RCA input?
The RCA connector (or RCA Phono connector or Phono connector) is a type of electrical connector commonly used to carry audio and video signals. The name RCA derives from the company Radio Corporation of America, which introduced the design in the 1930s.
Can a stereo cable be used as a single audio input?
There are occasions, though, when someone wants to treat that source device, perhaps a smart phone connection with cable terminating with an 1/8″ stereo plug, as a single (mono) audio input. You CANNOT simply wire it directly to a single balanced input!
How do you wire a stereo system with 3 wires?
Very often, an inexperienced audio person will attempt to wire the stereo pair’s three wires directly to the input’s 3-pin balanced input. They dutifully connect one signal to the plus terminal, the other signal to the negative terminal, and the shield to the ground terminal.
How to combine two signals into one mono signal?
The correct solution is to provide some sort of mixer circuit, so each output signal sees a relatively higher impedance and those two signals are then properly summed/mixed to a single mono output. The solution can be either an active mixer (expensive) or a simple inactive/passive mixer circuit (inexpensive).
Can I connect a stereo line-level device to an input channel?
It is not uncommon to try to connect a stereo line-level or headphone-level output device, such as a smartphone, PC audio output, or a CD player, to an input channel of some product.
