The banana plugs are the speaker line’s termination in the binding post’s hole, and the search for them is the search for the plug’s whole figure: the 4 mm pin, the spring’s grip, the current the plug carries, and the run it terminates. The banana is the home system’s standard connector – the plug that seats in the post’s 4 mm opening, the grip the spring’s pressure holds, and the polarity the post’s marking states. What follows sets out the banana plug’s build and the pin’s figure, the current class the plug carries, the polarity at the post, and the runs the banana terminates against the forms it works beside.

The Build – the Pin and the Body the Plug Carries

The banana plug’s build is the pin and the body, and the two figures are the plug’s specification. The pin is the 4 mm contact – the diameter the binding post’s hole states, the metal the spring’s pressure grips, and the face the post’s contact meets at the seat. The pin’s length is the figure the post’s depth needs, the projection that reaches the contact behind the hole’s opening. The body is the plug’s housing – the barrel the cable’s conductor lands in at the back, the grip the hand’s seat uses, and the insulation between the pin and the cable’s jacket. The build’s figures are the pin’s diameter and length, the body’s grip, and the conductor’s landing at the back – the solder or the crimp or the quick-connect the plug’s barrel states. The banana plug’s listing gives the build’s figures, and the install’s check is the pin’s diameter against the post’s hole, the figure the standard states.

The Current Class – the Plug’s Carrying Figure

The banana plug’s current class is the figure the home run’s environment states: the home amplifier’s output drive, the living room’s load, the current the run carries in the static environment. The plug’s contacts and the conductor’s landing are rated to that class – the pin’s face carrying the current from the post’s contact to the conductor behind it, the body’s barrel carrying it from the conductor to the pin. The current class is the home’s figure against the professional’s: the stage’s amp output and the PA cabinet’s draw are the class the locking Speakon serves, and the banana’s class is the home run’s. The plug’s listing states the current rating, and the install’s check is the run’s drive against the plug’s class – the figure the home environment keeps inside, and the professional’s the reason it moves to the lock.

The Polarity at the Post – the Marking the Plug Meets

The Post’s Marking – the Polarity’s Figure

The banana plug’s polarity is the post’s marking: the plus and the minus at the binding post, the color or the symbol that states the positive and the negative opening. The plug seats in the post the marking states – the positive pin in the plus opening, the negative in the minus – and the polarity is the figure the install reads at the seat. The post’s marking is the open terminal’s polarity enforcement: the reader’s eye against the mechanism, the figure the install checks at the connect. The banana’s polarity is honest when the install reads the marking and seats the plug to it, and the check is the two pins against the two markings, the figure the pair’s connection depends on.

The Pair – the Plug’s Two in the Run’s Polarity

The banana plug’s pair is the run’s polarity in the two plugs: the positive plug on the positive conductor, the negative on the negative, the pair’s polarity matching the run’s. The cable’s two conductors land in the two plugs’ barrels at the back, and the pair’s polarity is the figure the wiring keeps at the termination – the positive conductor in the positive plug, the negative in the negative. The pair’s polarity honest at the plugs is the polarity honest at the post, and the check is the two: the conductors’ landing at the barrels, and the plugs’ seating at the post’s markings. The banana plug’s pair is the speaker line’s polarity in the two forms, and the run’s correctness is the figure the two checks keep.

The Runs the Banana Terminates – and the Forms It Works Beside

The banana plug terminates the home speaker run, and the runs repeat: the amplifier’s binding post to the speaker’s, the living room’s pair; the receiver’s speaker output to the front pair, the home theater’s static run; and the install’s permanent seating, the banana in the post the run’s life holds. The banana works beside the spade in the post’s two openings – the hole for the banana, the slot for the spade, the post’s design accepting both – and it works against the bare wire’s clamp, the screw’s seating the strands the banana’s pin seats. The form’s choice at the post is the install’s: the banana for the quick connect and disconnect, the spade for the slot’s grip, the bare for the permanent clamp. The banana’s figure is the quick seat in the home environment, and the professional’s lock is the form the stage’s grip states beyond it.

the Banana Plug in Its Figures

Real-World Application Scenarios

The banana plug works in the three runs that repeat: the home amplifier to the speaker pair, the living room’s quick connect; the receiver to the front speakers, the home theater’s static run; and the install’s seating, the banana in the post the run holds through the years. In each, the plug’s figures are the 4 mm pin, the spring’s grip, the home current class, and the polarity at the post’s marking.
