Sound Devices A20-HH Custom Kit (8-Pack)

Complete Modular Bundle for Eight A20-HH Wireless Microphones
The Sound Devices A20-HH Custom Kit-8 provides a comprehensive set of modular components to assemble and personalize eight A20-HH digital handheld microphones. Designed for rental houses, touring engineers, broadcast teams, or production professionals who demand flexibility and customization, this kit includes all key accessories—CD1 capsules, control rings, collars, body shells, clips, and protective pouches. It’s ready to be deployed, customized, or branded to fit any event, tour, or show.

Factory-Calibrated CD1 Capsules for Uniform Sound
This kit includes eight CD1 dynamic cardioid capsules, each 100% factory-calibrated to ensure consistent frequency response and sensitivity across every unit. Designed specifically for vocal clarity, the CD1 capsule features a cardioid pattern optimized for live and broadcast use, with a smooth response from 50 Hz to 15 kHz. Its dual-diaphragm, dual-voice coil structure ensures minimal handling noise and uniform polar behavior across the frequency spectrum.

Durable Modular Shells Built for Customization
Every kit includes eight A20-HH Body Shells that are paintable and easy to replace. Whether you're branding your microphones with logos, coordinating mic colors with costumes, or simply customizing the appearance, these rugged shells make it simple. Designed for road use, each shell is weather-resistant and built to handle stage abuse, making them ideal for touring productions and live broadcasts.

Flexible Thread Compatibility with Reversible Collars
Included in the kit are eight A20-HH Capsule Collars—modular thread adapters that support both Shure and Sennheiser-style capsules without the need for external adapters. Flip the collar to switch formats in seconds. This flexibility enables you to use a wide range of capsules with your A20-HH system, keeping your workflow agile while reducing gear redundancy.

Control Ring Simplicity with LED Status Indicators
Each A20-HH transmitter build includes the A20-HH Control 0 Ring, which features no physical buttons and a clean design, ideal for performers who don’t need on-mic interaction. It does include a multicolor status/audio level LED, giving talent and techs visual feedback without clutter or complications. As always, rings are swappable with other control ring types for expanded functionality if needed.

Pouches and Clips for Transport and Performance
Rounding out the kit are eight A20-HH Pouches and eight A20-HH Mic Clips. The pouch features a soft interior and durable exterior, perfect for protecting the microphone during transit and storage. The mic clip features a threaded adapter compatible with both 3/8" and 5/8" stands, with a smooth-fit angle for easy slide-in and removal during live use. Together, these accessories provide the convenience and durability needed for daily professional use.
