Universal Audio SP-1

Universal Audio SP-1 | Matched Pair Small-Diaphragm Cardioid Condenser Microphones for Stereo Recording

A matched pair of small-diaphragm condenser microphones for high-resolution stereo capture

Universal Audio SP-1 is a matched pair of small-diaphragm condenser microphones from Universal Audio. It features a cardioid polar pattern, a 20Hz–20kHz frequency response, and built-in Hemisphere modeling technology that expands into five classic small-diaphragm condenser mic tones. Centered on pair-matching consistency, this microphone set is especially suitable for creators and recording engineers working on stereo recording, acoustic guitar recording, drum overheads, piano, and other highly detailed sources.

Compared with the traditional approach of matching two single small-diaphragm microphones by yourself, the Universal Audio SP-1 greatly lowers the barrier to left-right tonal matching, placement, and phase management thanks to its factory-matched pair and included stereo T-bar. Compared with similar purely hardware-based small-diaphragm microphones, the SP-1 stands out by combining Hemisphere modeling with proximity and axis adjustments, giving you greater flexibility for correction and shaping even after recording.

Who Should Buy

Home studio creators who want accurate stereo capture in one go while also recording acoustic guitar, drums, piano, and other instruments
Content creators or arrangers who want an easy-to-use matched pair of small-diaphragm microphones and do not want to choose two single mics with unknown consistency
Recording beginners who want to quickly build an XY setup with the stereo T-bar and reduce the difficulty of placement and phase handling
Existing Universal Audio users who want to combine Apollo Presets and Hemisphere modeling to improve recording efficiency and post-production flexibility

Who Should NOT Buy

Users who only need a single vocal microphone; this product is positioned more toward instruments and stereo recording than solo lead vocals
Beginners on a tight budget who only do simple voice recording may not fully benefit from the matched-pair and modeling features
Recordists who already own a high-end matched pair of small-diaphragm microphones and do not need a modeling workflow may have less reason to invest again

Universal Audio SP-1 Core Technology and Features

Factory-matched small-diaphragm design: SP-1 includes two matched condenser microphones, delivering more consistent frequency response, transient response, and stereo imaging between left and right channels, making it ideal for stereo recording workflows.
High-resolution stereo capture: For acoustic guitar, drum overheads, piano, percussion, and chamber instruments, it accurately captures detail, air, and spatial depth for a more complete and natural stereo image.
Cardioid pattern reduces ambient interference: The cardioid design helps reduce unwanted room reflections and background noise from the sides and rear, keeping the main source focused and clearly defined.
20Hz–20kHz full-range frequency response: Covers low-end foundation, midrange texture, and high-end extension, faithfully reproducing string plucks, cymbal air, and piano harmonic structure.
Hemisphere modeling technology: Includes the Hemisphere microphone modeling plug-in, giving access to five classic small-diaphragm condenser models so one hardware set can deliver more tonal possibilities.
Real-time modeled monitoring workflow: You can monitor and make production decisions using modeled tones during recording, shortening the time from capture to mix and improving efficiency.
Post-production proximity and axis control: Hemisphere supports proximity, axis, and filter parameters, allowing you to shape the sound during recording or fine-tune distance, angle, and filtering after the take.
Apollo Channel Strip Presets integration: When paired with a compatible Universal Audio Apollo audio interface, you can quickly load channel presets optimized for SP-1 and get EQ and compression results closer to a finished mix.
Quick stereo setup with T-bar: The included T-bar lets two microphones mount on a single mic stand for an XY stereo setup, lowering the barrier for beginners in terms of angle, spacing, and phase.
Ready-to-record out of the box: From factory matching and modeling plug-ins to stereo mounting accessories, the entire design is aimed at helping users get to a usable, listenable, deliverable recording state faster.

Hemisphere Microphone Modeling Technology

Inherits the concept of Universal Audio Sphere software and brings modeling capability to the Standard series microphones, making the SP-1 more than just a traditional small-diaphragm condenser microphone set.
Includes 5 classic small-diaphragm condenser microphone models, allowing you to switch to brighter, smoother, more detailed, or more forward recording styles depending on the source.
For creators who need both recording efficiency and tonal flexibility, it provides a broader sonic palette from a single hardware investment.

5 Classic Small-Diaphragm Condenser Modeling Tones

SD-54: A classic studio small-diaphragm tone, ideal for natural, balanced, and highly reliable stereo capture.
SD-56: Features silky highs and a softer low-end contour, especially useful for acoustic guitar, piano, and delicate instruments.
SD-84: Known for clear detail and a modern high-end character, suitable for instrument recording that needs more definition and presence.
SD-86: Delivers a crisp top end and warmer mids, practical for users who want both brightness and musicality.
SD-451: Offers a more forward, brighter tonal direction, suitable for drum kits, piano, and recording applications that need more presence.

Post-Production Proximity, Axis, and Filter Controls

The proximity control can virtually change the perceived distance between the microphone and the source, helping adjust low-end thickness, closeness, and room proportion.
The axis control can simulate changes in microphone incidence angle inside the plug-in, helping tame harsh frequency areas and especially useful for guitar amps, snare drums, and bright sources.
The filter control can further reduce low-end buildup or unwanted energy, making it easier to obtain clean, usable material during recording and mixing.
The biggest advantage is that these adjustments do not need to be finalized during recording; they can still be fine-tuned afterward, reducing the risk of a bad take.

Stereo Recording Setup and Phase Management Advantages

The greatest value of a matched pair of small-diaphragm microphones is that the left and right channels can maintain consistency more reliably, creating a natural and stable stereo image.
The included T-bar quickly enables an XY stereo setup, allowing two microphones to be mounted on a single stand, saving space and making standardized placement easier to reproduce.
For drum overheads, dual-mic acoustic guitar, piano, and ambient recording, it helps reduce muddiness caused by left-right imbalance and phase issues.

Quick Access to Usable Tones with Apollo Presets

When used with a compatible Apollo audio interface, you can load Apollo Channel Strip Presets optimized for SP-1 and quickly apply EQ and compression direction.
For users who need to deliver demos, arrangement drafts, or commercial content quickly, it shortens the time from raw capture to a usable final result.
These presets are especially suitable for creators who do not want to start from scratch every time, helping them achieve a near-finished sound with a lower learning curve.
