A PAIR (one red, one black) OF GOLD-PLATED 4mm BANANA PLUGS (Please see photo)
These 4mm plugs enable a very high quality connection in domestic HI-Fi and Professional Studio speaker systems where large diameter cables are used.
They can be stacked end on end with other 4mm plugs or cable / plugs up to 7mm can be inserted through the side of the plug and clamped by the screw mechanism.
Available in any quantity - please telephone or email for prices.
I have been using these In my studio (Crown and Quad amps, Tannoy Super Gold & Tannoy Reveal monitors) and Domestic hI-fi for the past 20 years without a breakdown or hitch.
