Shure RPMDL4FC/T – DL4/DH5 DuraPlex Frequency Cap, Tan (5-Pack)

Product Overview

The Shure RPMDL4FC/T is the frequency cap for the DL4 DuraPlex lavalier and DH5 DuraPlex headset microphones, in tan, supplied in a pack of five. The cap fits over the microphone capsule and boosts approximately 3–4 dB in the 10 kHz range, adding upper-frequency presence to speech and vocal capture for improved intelligibility. The tan finish coordinates with lighter skin tones and clothing for discreet deployment in broadcast, corporate, and theater production environments.

Product Description

The RPMDL4FC/T presence cap adds a capsule-level 10 kHz boost to the DL4 or DH5, improving speech clarity in reverberant spaces such as large conference rooms, houses of worship, and auditoriums — without requiring any change at the transmitter or mixing console. The tan finish is suited for lighter skin tones and is the standard choice for DL4/DH5 deployments on presenters with lighter complexions or wearing light-colored formal attire. Five caps per pack provides production-scale coverage for multi-mic inventories. This cap is the OEM replacement for the presence cap included with the DL4 and DH5 at purchase.
