Product Overview

The Ultimate Drum and Amplifier Multi-Pack for Modern Hybrid Studios

The Universal Audio SD-3 3-Pack brings unmatched value and sonic adaptability to multi-microphone tracking environments. Recording a cohesive drum kit or a complex guitar backline usually requires deploying multiple specialized microphones, which can quickly exhaust a studio's budget. By packaging three high-performance, compact SD-3 dynamic microphones into a single retail bundle, Universal Audio offers a unified tracking solution that ensures structural consistency, tonal balance, and identical frequency baselines across your entire drum shell setup or multi-cabinet guitar rigs.

While these microphones deliver a beautifully punchy, smooth sound in their passive analog state, the inclusion of the free Hemisphere Mic Collection software transforms this trio into a comprehensive multi-mic network. Since the software loads individually on each DAW track insert, you can assign completely different classic microphone personalities to each individual physical mic. This allows you to run a vintage broadcast capsule emulation on your snare drum while simultaneously treating your rack and floor toms with aggressive, modern punch—all using the same physical microphone model.

Product Description

Three-Point Acoustic Coverage for Phase-Consistent Tracks:

Using identical microphones across multiple matching sound sources—such as rack toms, floor toms, or side-by-side guitar speakers—is a major secret to achieving a professional mix. The SD-3 3-Pack ensures that the transient response, phase characteristics, and capsule sensitivity remain perfectly matched across your tracking channels. This uniformity eliminates uneven phase cancelation and irregular frequency spikes, giving you an organic, tightly locked foundation that sits cleanly in your mix.

Compact, Low-Profile Shells for Tight Spatial Placement:

Each individual SD-3 microphone is built with a highly compact, low-profile chassis measuring just 3.58 inches in length. This miniature form factor is specifically designed to fit easily into ultra-tight spaces where bulky standard dynamic microphones cannot navigate. It allows you to position the capsule deep within complex drum setups—close to the drum head and safely out of the way of a drummer's flailing sticks—or position it directly against a guitar amplifier’s cloth grille with millimeter precision.

Harness Five Legendary Microphones Simultaneously:

The companion Hemisphere Mic Modeling plug-in runs natively inside your DAW (VST, AU, AAX) or in real-time through Apollo hardware. It lets you adjust the virtual proximity effect to alter low-end warmth, change the virtual axis angle to tame harsh high-frequency cymbals, or toggle between five renowned dynamic microphone emulations independently on all three channels:

• DN-57: Emulates the industry-standard, mid-forward dynamic microphone used on almost every hit record since 1965—perfect for giving snare drums immediate bite and crack.

• DN-545: Based on the historic Unidyne III capsule layout used to record Brian Wilson’s lead vocals on Pet Sounds, delivering a smooth, classic mid-century warmth.

• DN-604: Models the current-production, European compact clip-on dynamic microphone that is a global studio standard for handling aggressive, fast percussion attacks.

• DN-409U: Recreates a highly sought-after German companion microphone that adds incredible low-end body, punch, and smoothness to electric guitar cabinets.

• DN-4: Recreates a modern, punchy compact instrument microphone engineered to help percussion and low-mid brass frequencies punch effortlessly through dense modern arrangements.

Tour-Ready Durability and Elegant Styling:

Every microphone in the SD-3 Trio Pack features an all-metal chassis with Universal Audio’s signature retro-modern cream finish and heavy-duty protective grilles. This passive dynamic system requires no 48V phantom power, making it incredibly durable and resistant to high acoustic signals. To ensure a complete setup right out of the box, the package ships with three dedicated standmounts with internal thread adapters and a custom protective storage pouch to keep your trio safe during transport or storage.
