The Slate Digital ML-1A Modelling Microphone is a large-diaphragm condenser designed as the recording front end for Slate Digital's Virtual Microphone System, allowing recordings to be shaped using a wide range of virtual microphone models after tracking.

Compared with the original ML-1, the ML-1A introduces significantly improved technical performance, including just 8dBA self-noise, an 86dB signal-to-noise ratio and a three-position 0/-10/-20dB pad capable of handling sources up to 145dB SPL.

This pre-owned example is presented in Excellent Condition and supplied with a protective hardcase.

Importantly, the associated Slate Digital software has been de-registered from the previous owner, and a new software activation code is included in the box, allowing the new owner to register the microphone and associated software to their own Slate Digital/iLok account.

Condition Overview

Excellent Condition

This Slate Digital ML-1A is presented in Excellent Condition.

Under the Fair Deal Music grading system, Excellent Condition means the microphone shows very light signs of previous use while remaining particularly well presented and fully functional.

Software Transfer Completed

An especially important part of this package is that the associated software licence has already been prepared for transfer.

• Previous software registration has been removed
• A new activation / redemption code is included
• Code is supplied in the box
• New owner can register the ML-1A to their own Slate Digital account
• Compatible iLok account is required for software activation

This avoids the buyer receiving a microphone whose software remains tied to a previous owner's account.

What's Included?

✔ Slate Digital ML-1A Modelling Microphone
✔ Hardcase
✔ New Slate Digital Software Activation Code
✔ Software De-Registered from Previous Owner

Any additional accessories are included only where pictured or stated.

Software Registration

New Activation Code Included

The original owner has had the Slate Digital software de-registered, and a replacement activation code is included with the microphone.

The new owner can use this code together with the microphone's serial number to register the ML-1A to their own Slate Digital account.

Once correctly registered, the appropriate VMS ML-1A licence is deposited into the user's linked iLok account.

This is particularly important when buying a used modelling microphone because the physical microphone forms only one part of the complete ML-1A workflow.

What Makes The Slate Digital ML-1A Special?

The ML-1A is deliberately designed to capture a clean, neutral source signal.

Rather than committing permanently to the colour of a particular vintage-style microphone during recording, the captured audio can subsequently be processed through Slate Digital's Virtual Microphone System.

This allows the engineer to audition different microphone characters:

• While recording
• During editing
• During mixing
• After the performer has left
• Without re-recording the source

That flexibility can be particularly valuable when working quickly or recording artists who perform better without repeated microphone comparisons.

Virtual Microphone System

The Virtual Microphone System uses the ML-1A as its calibrated physical source microphone.

Within the software, the recorded signal can then be processed through virtual microphone models inspired by a broad range of studio microphone designs.

The system also provides creative controls including:

• Microphone model selection
• Mic model morphing
• Proximity adjustment
• Width control
• Rumble filtering
• Virtual preamp processing

This makes the ML-1A considerably more than a conventional large-diaphragm condenser.

Mic Model Morphing

One of the newer VMS functions allows two microphone models to be blended together.

Rather than being restricted to selecting one virtual microphone, the user can combine characteristics from two models to create intermediate or hybrid sounds.

This can be particularly useful for finding a vocal tone that sits naturally within a dense mix.

Proximity Control

The VMS proximity control allows the perceived proximity effect to be adjusted after recording.

This can help:

• Add body to a thin vocal
• Reduce excessive low-end buildup
• Refine spoken-word recordings
• Balance close-miked sources

It provides a level of post-recording control that is impossible with a conventional fixed microphone recording.

Width Control

The VMS software can also introduce adjustable stereo width from the ML-1A's mono source recording.

This can be useful for:

• Backing vocals
• Layered arrangements
• Sound design
• Cinematic textures
• Creative vocal production

Large-Diaphragm Condenser Design

The ML-1A uses a 1" / 25.4mm condenser diaphragm.

Large-diaphragm condensers are commonly chosen for:

• Lead vocals
• Voiceover
• Acoustic guitar
• Piano
• Guitar cabinets
• Room microphones
• Percussion
• General studio recording

The microphone's clean source response is specifically designed to provide an appropriate foundation for subsequent modelling.

Low Self-Noise

The ML-1A has a rated self-noise figure of only:

8dBA

This is a substantial improvement over the original ML-1's 17dBA specification.

Low self-noise is particularly valuable when recording:

• Quiet singers
• Spoken word
• Delicate acoustic instruments
• Distant sources
• Ambient material
• Sources requiring substantial preamp gain

86dB Signal-To-Noise Ratio

The ML-1A offers an 86dB A-weighted signal-to-noise ratio, helping capture clean material with minimal unwanted noise contribution from the microphone itself.

Three-Position Pad

The ML-1A features a hardware pad with three settings:

• 0dB
• -10dB
• -20dB

Using the -20dB setting allows the microphone to handle sound pressure levels of up to approximately 145dB SPL.

This significantly expands its usefulness with loud sources.

Suitable For Loud Sources

With the pad engaged, the ML-1A can be used on sources including:

• Guitar amplifiers
• Loud vocalists
• Brass
• Percussion
• Drum room positions
• Powerful acoustic instruments

This makes it substantially more versatile than a microphone designed purely around vocal recording.

Cardioid Polar Pattern

The ML-1A uses a fixed cardioid polar pattern.

Cardioid microphones primarily capture sound arriving from the front while reducing pickup from the rear.

This makes the microphone particularly useful for:

• Vocal isolation
• Home studios
• Reducing room reflections
• Instrument recording
• Controlling bleed between performers

Who Is It For?

Power Requirements

The Slate Digital ML-1A requires 48V phantom power from a compatible:

• Audio interface
• Microphone preamp
• Mixing console
• Channel strip

No external dedicated power supply is required.

A suitable XLR microphone cable and phantom-powered input are required for operation.

Audio Interface Requirements

The ML-1A itself outputs a conventional analogue microphone-level XLR signal.

It therefore requires a suitable microphone preamp or audio interface.

For best modelling results, the recording chain should generally be kept clean and neutral before the VMS software is applied.

Software Requirements

The ML-1A uses Slate Digital's Virtual Microphone System software.

A compatible computer, DAW and Slate Digital/iLok account are required for the software workflow.

Current supported plugin formats include:

• AAX
• AU
• VST2
• VST3

Software compatibility should always be checked against the buyer's current operating system and DAW before purchase.

Software Licence Transfer Note

The software associated with this microphone has been de-registered from its previous owner.

A new activation code is included in the box for the purchaser.

The buyer will need to:

1. Create or use their own Slate Digital account
2. Enter the supplied activation code
3. Register the ML-1A serial number
4. Link an iLok account
5. Download the relevant Slate Digital software

This provides the buyer with a clean registration route rather than relying on access to the previous owner's account.

Hardcase

A hardcase is included with this microphone.

This provides useful protection during:

• Transport
• Studio storage
• Mobile recording
• Session work

Fair Deal Music Verdict

★★★★★ 5/5

The Slate Digital ML-1A is an extremely flexible studio microphone for producers who value the ability to make tonal decisions after the recording has already taken place.

Its 1" condenser capsule, exceptionally low 8dBA self-noise and 0/-10/-20dB hardware pad make it suitable for considerably more than vocals, while the VMS software transforms the clean source recording into a highly adaptable production tool.

This example is particularly attractive as a pre-owned purchase because the software has already been de-registered from its previous owner and a brand-new activation code is included in the box.

That means the new owner can register the microphone and software under their own account rather than receiving hardware whose associated licence remains tied elsewhere.

Presented in Excellent Condition and supplied with a hardcase, this is a particularly complete used ML-1A package for studio recording, vocal production, voiceover and content creation.
