- Take a multimeter placed on the setting for the insulation and continuity tests then press “select” to set it in Ohm meter.
- The black banana-type cable and plugged it into the COM port.
- the red banana cable will be placed on the resistance measurement port as in photo number 1.
How many volts should RCA cables have?
LOW LEVEL (RCA)
A good quality RCA audio source should have a voltage rating around 1-2 Volts and a low impedance. The voltage is the “strength” of the signal and the “impedance” relates to signal integrity once the RCA is plugged into the amplifier.
How do you test RCA output on a head unit?
How much resistance should an RCA cable have?
Suffice to say you need a 75 ohm coaxial cable (often called “video” cable) for the best results in terms of an RCA cable.
