Here is a little money saving tip for running cables to powered monitors and PA speakers. In the past it was a firm rule that you should only use “speaker cables” for these applications. Speaker cables are built heavier to carry the boosted signal coming from a power amplifier where as line level cables such as instrument, patch, and microphone cables are not designed to handle this increased load. Since most of the studio monitors as well as many of the PA main speakers on the market today are self powered, the rule does not apply in powered speaker applications.

Since the signal in powered speakers is not amplified until after it reaches the speakers internal amplifier, you will money and get the right connection by using line level cables instead of the generally more expensive speaker cables. I personally prefer to use balanced XLR cables since their signal is stronger and much more resistant to unwanted noise and interference. If you do decide to go this route, you will want to make sure your speakers as well as your signal source are set up for XLR input or output. If this isn’t the case, a TRS (Tip-Ring-Sleeve) cable will work just fine.

If you are upgrading from unpowered speakers to powered models, you really should consider switching out your old speaker cables for line level cables. Speaker cables will still work, but have an extreme likelihood of affecting the sound quality in adverse ways. Using the correct cabling for the appropriate hookup will always yield the best result in every musical application.

I would like to note that if you are still using unpowered speakers with a power amplifier, you will still need to follow the important rule of using only quality dedicated speaker cables to make the connection.
