For phono outputs (record players, microphones, etc.) good shielding against interference fields is particularly important. This is provided by the WBT-0102 that features the brass sleeve of higher conductivity connected to the minus pole – but otherwise is all nextgen™. (75 ohms up to 200 MHz) Utilizes pure copper contacts. The maximum size conductor that can be used is 1.5mm² / 16-17 AWG. Maximum diameter of cable with dielectric is 9.1-11.3 mm² / 0.358-0.445 inches². The barrel is offered in black only.
