The Zaxcom IFB Receiver Replacement Knob (5-Pack) is a precision-printed spare part designed specifically for the Zaxcom ERX3TCD Digital IFB Receiver. These replacement knobs deliver perfect snap fitment that matches the original factory specification — restoring full control of your IFB receiver quickly and affordably when the original knob cracks, strips, or goes missing on set.
Selling as a 5-pack means you'll have spares on hand for future replacements or to share across a sound department managing multiple ERX3TCD units. The knobs are printed from durable material to withstand daily handling and the wear of professional production environments.
The Zaxcom ERX3TCD is a staple of professional sound departments worldwide, and small hardware failures like worn or missing knobs shouldn't take a receiver out of service. This affordable replacement pack keeps your IFB system operational without the lead time or cost of a full unit repair.
