Banana Plugs, Jacks and Cables

Banana Plugs

Banana plugs have a bulge metal leaf with a fine cylindrical pin. The snug fit keeps the plug tightly fit into binding posts. You have seen back end of the pin has often screwed, soldered or crimped. 

    The main purpose of banana plugs is making a secure and perfect connection to equipment. Banana Plugs connect a receiver or amplifier to your amp or speaker. But if you don’t have banana pins to your receiver, you can use bare wires.

    Bare wires often look untidy and when you want to move the speaker, it has been a tedious task. In this case, banana plugs will come to your rescue and you feel relaxed from the manual tightening of bare wires. 

     Banana plugs are convenient for wall installations as compared to bare wires. It also saves you from an accidental short circuit.

Banana Jack

Banana jacks are the female connectors that are fit nicely to the male connector banana plugs. It has various dimensions where different types of plugs can be fitted easily. 

      The ideal jacks have five-way binding posts that are bare wires, spade connectors, pin connectors, banana plugs, and dual banana plugs.

Banana Cables

Now, you have the plugs and jacks but without cable, the signal won’t transmit to your speaker. Banana cable is a medium to connect male plugs and female jacks. 

    It transfers the signal from the receiver to speaker. Copper coated cables are ideal choices but they should be properly insulated. Otherwise, copper will react with oxygen to form copper oxide.

Product characteristics of banana plugs

 

Installation

Installation comes with soldering, crimping, screw fitting, and auto install. For soldering, you should have a nice soldering iron that can make soldering your cable wire to plugs.

   For crimping, the wire is crimped around nicely to connect plugs. Screw fitting comes with two types, open screw type, and close screw type.

   Wider gauge wire can be nicely fit into open screw type while close screw type is suitable for narrow gauge wire. In auto install, just open the cable of the plug, fit your wire nicely and tighten the cable. Now, the plug has long lasted and no need of reinstalling multiple times.

Shrouded and Unshrouded

Shrouded plugs have proper insulation coverings while unshrouded has no insulation coverings. It is often termed as sheathed and unsheathed.

Retractable and Unretractable

Retractable plugs have a spring-loaded sheathed cover which can be opened and closed. However, unretracted plugs have no spring-loaded sheathed cover.

Body Structure

The best body structure comes with high-quality brass and it has a gold plating for a better signal. Plugs will come with high or low-quality materials body structure and plating.



Color coding

Most of the plugs will come with red and black color coding for nice polarity identification. However, some plugs come with without color coding.

Acceptance of AWG wires

The best quality plugs can fit into 12 to 18 AWG wires. Some plugs can support 8- 18 AWG wires while some can support only 8 AWG wires.

Compatibility

The best quality plugs are compatible with bare wires and spade connectors. Some plugs will support only bare wires while some plugs support only spade connectors.

Screw type

The ideal plug is closed screw type which can give the fine finishing of your plug. However, a quality number of plugs will come with an open screw type.

Warranty

You will get the lifetime warranty for gold plated plugs. Plugs without gold plating can have one to five years of warranty. It depends upon the specific company policy.

                       How to install banana plugs on speaker wire

Special attention for buying banana plugs

 

Avoid traditional soldering or crimping banana plugs. Soldering unnecessarily produces fumes and smoke. If you are highly expert in crimping, then only use crimped banana plugs. Always purchase a mechanical plug where you can fasten the screws by screwdrivers.

Gold plating body will give you the best audio fidelity. Audio fidelity will define from four key factors that are ‘frequency response’, ‘distortion’, ‘noise’, and ‘time-based errors’. So, for a nice and clear sound quality always use the gold plated plugs.

Gold plated not only gives the best audio fidelity but also prevents from corrosion. So using gold plating plugs can be long-lasting.

Before purchasing plugs, see specifically your cable dimensions. Your wire gauge must match the correct banana plugs.

Non-collapsing tips maintain the shape of your plugs even if you can remove and insert multiple numbers of times. So for better durability pick non-collapsing tips.

Always use the best sound quality banana plugs. Sound quality can be best determined by impedance level. The low impedance level tells that there is no flaw of design and they are perfect in sound quality.

 If you want a firm grip to your socket, then it is better to choose a 9 leaf banana plug as compared to 4 leaf banana plugs.

 Dual banana plugs will create a desired pressure on the wire. Ultimately you will get the maximum output. If your jack supports dual banana plugs, then I suggest you purchase dual ones.

 Choose low resistance banana cable, because of lower the resistance, higher the sound quality. So, you should choose thick wire, low gauge, and short length cable for enhanced sound quality.

 Most of the banana plugs will come with 12 pairs while some come with 6 pairs and 14 pairs. So, if you are getting a high pair of plugs at an affordable price, then I suggest you get the maximum pair of plugs.
