FAQ: SD-7 Dynamic Microphone with Hemisphere Modeling

This article answers frequently asked questions about SD-7.

Getting Started

What is SD-7?

Universal Audio’s SD-7 is a hypercardioid dynamic microphone featuring Hemisphere mic modeling technology, high SPL tolerance, and included accessories.

Which cable should I use for SD-7?

A standard, balanced, 3-pin XLR cable. Pin 2 is Hot.

How do I mount SD-7?

SD-7 has an integrated standmount with angle adjustment. The standmount includes a pre-installed 5/8" to 3/8" adapter that can be removed for 5/8" mic stands. For 3/8" mic stands, leave the adapter in place.

What is the polar pattern of SD-7?

SD-7 has a fixed hypercardioid polar pattern.

How should SD-7 be positioned?

SD-7 is an end address microphone, meaning sound enters through the black grille at the top of the mic. Point the top of the microphone towards the sound source. Its hypercardioid polar pattern provides the most rejection at 135°, which can be used to eliminate unwanted sounds such as cymbals and hi-hats when positioned off-axis.

Does SD-7 come with any plug-ins or software?

SD-7 includes the Hemisphere Mic Collection plug-in. Using the same award-winning tech as our UA Sphere modeling microphones, Hemisphere gives your studio the authentic sound of essential microphones — in realtime with Apollo or natively in your DAW. You can also shape the sound of your recordings using filter, proximity, and axis controls — even after tracking.

There are no Apollo Channel Strip Presets offered with SD-7, but plenty of presets in the Hemisphere plug-in itself!
