Focusrite Vocaster One
A single-XLR podcasting interface with 70dB of gain on tap — Focusrite built it to make one voice sound like it belongs on the radio.
Overview
The Vocaster One is a compact USB-C audio interface from Focusrite, aimed squarely at solo content creators — podcasters, vloggers, voiceover artists, streamers, audiobook creators, and the rest. It carries the model/SKU AMS-VOCASTER-ONE and ships in black, with a UPC of 065030860789. The premise is simple: one microphone, one host, one show, and a signal chain short enough that a beginner can be recording within minutes of unboxing.
The centerpiece is a single XLR microphone input on the rear panel, rated for 70dB of gain — a figure corroborated across Focusrite's own documentation, MusicRadar, and retailer listings. That's a serious amount of clean gain for an interface in this class, and it's the number that matters most for anyone planning to run a dynamic microphone, which typically demands far more amplification than a condenser. The input accepts both dynamic and condenser types, and a rear-panel switch engages 48V phantom power when a condenser needs it. Conversion runs at up to 24-bit resolution and a 48kHz sample rate over the USB-C connection — the manual flatly notes that 24-bit/48kHz is the standard for most podcasts, which is a fair summary of where the format sits.
Around the mic input, Focusrite has built the features that make the Vocaster One feel less like a bare interface and more like a small studio in a box. The microphone gain knob is surrounded by "halo" meters that display both signal level and gain setting simultaneously, so you can see what you're doing without a DAW open. Three illuminated buttons handle Auto Gain, Enhance, and mute. Auto Gain sets the level for you; Enhance applies one of three presets to shape the tone. LEDs confirm when phantom power and the USB connection are active. It's a deliberately simplified control surface, and the design goal stated in the manual is exactly that: to get users of all experience levels to clear, consistent recordings quickly.
Connectivity extends beyond the computer. A 3.5mm TRRS jack on the rear panel provides a two-way phone connection — audio in and out — so you can pull a remote interview off a phone and record it, or feed the phone your mix. A second 3.5mm TRS socket connects to a video camera, letting you record audio to the camera's track in sync with the video rather than syncing in post. Monitoring is handled either through the front-panel ¼" TRS headphone socket or a pair of rear-panel ¼" TRS sockets for speakers, with listening level controlled from the top panel.
The unit weighs 348g and measures 195mm wide, 50mm tall, and 113mm deep — small enough to sit on a desk beside a laptop without crowding it, which is presumably what Thomann meant by calling it "compact." Focusrite's manual states the Vocaster One is compatible with Mac and Windows, and with Apple iPads that have a USB-C port, so the tablet-only crowd isn't locked out.
Key Features
70dB Microphone Gain Range
Seventy decibels of gain is the headline number here. For context, that's enough headroom to drive low-output dynamic microphones — the kind podcasters often prefer for their rejection of room noise — without pushing the preamp into audible hiss. The figure appears consistently across Focusrite's site, MusicRadar, and retailer documentation, which is about as solid as corroboration gets. The mic input is a balanced female XLR on the rear panel, and the manual notes the interface accepts a range of microphone models, including both dynamic and condenser types.
48V Phantom Power with Rear-Panel Switch
Condenser microphones need phantom power, and the Vocaster One supplies it at 48V via a dedicated rear-panel switch. Two LED indicators on the top panel show when phantom power and the USB connection are active, so there's no guessing whether the mic is actually receiving voltage. It's a small thing, but on an interface aimed at beginners, visible confirmation of phantom power status prevents a lot of confused troubleshooting.
Halo Meters Around the Mic Gain Knob
The microphone gain control is ringed by what Focusrite calls "halo" meters, which display both the microphone signal level and the gain setting at the same time. This is the feature that most defines the Vocaster One's user experience — you can set gain by eye without opening any software. The manual describes the meter behavior in the Vocaster Hub software, where the bar should stay green most of the time, with amber only on the loudest peaks, and red indicating the gain is set too high. The hardware halo mirrors that logic.
Auto Gain, Enhance, and Mute Buttons
Three illuminated buttons sit on the top panel: Auto Gain, Enhance, and mute. Auto Gain handles level adjustment automatically — Thomann's listing describes it as a "function for level adjustment," and the manual frames it as one of the tools that lets users of all experience levels achieve clear, consistent recordings quickly. Enhance offers three presets for tonal shaping, confirmed by both Thomann and thomannmusic.com. The mute button does exactly what it says. None of this is exotic, but the combination is what makes the Vocaster One approachable for someone who has never touched a preamp before.
Two-Way Phone Connection via 3.5mm TRRS
The rear-panel 3.5mm TRRS jack is a genuinely useful inclusion for interview-based shows. TRRS means the connection carries audio both in and out of the phone, so you can record a remote guest's audio directly from a phone call and simultaneously send your own mix back to them. The manual explicitly frames this as a way to "record interviews or other audio from your phone to your camera or computer." For solo creators who occasionally bring on a guest, it's a cheaper and simpler solution than a dedicated phone hybrid.
Camera Output for Sync Recording
A second 3.5mm TRS jack on the rear panel connects to a video camera's external audio input. The manual states you can "record to the audio track of a camera in perfect sync with your video" — meaning no post-production sync step. For vloggers who shoot on a camera and want better audio than the onboard mic provides, this is the feature that makes the Vocaster One a one-stop shop rather than a computer-only interface.
Vocaster Hub Software
The Vocaster One ships with Vocaster Hub, a companion application that Focusrite describes as "designed with simplicity in mind." It provides access to settings and gives full control of the show's mix as it's sent to recording or streaming software. The software also unlocks loopback — MusicRadar lists "two stereo streams accessed via Vocaster Hub software" — and handles the USB stream routing, which MusicRadar specifies as "10 in 4 out." The Hub duplicates the hardware controls (mic level, the three buttons) on screen, so you can work entirely in software if you prefer. Focusrite recommends installing it, noting it "unlocks the full potential of the interface."
USB-C Connectivity and Bus Power
The Vocaster One connects via a USB-C port on the rear panel and is powered over that same connection — the manual instructs users to power it on by pressing the power button next to the rear USB port. A USB Type-A to Type-C cable is included in the box. On first connection, the manual notes, your computer recognises it "in the same way as if it were a USB memory stick," which is a pleasantly frictionless way to describe driver installation. Focusrite also notes that on Windows, the driver installs automatically when Vocaster Hub is installed.
Historical Context
The Vocaster One is part of Focusrite's Vocaster range, which also includes the Vocaster Two and the Vocaster One Studio bundle (the latter pairing the interface with a Vocaster DM1 dynamic microphone and HP60v headphones). A comparison published by specsradar.com concluded that the Vocaster Two and Vocaster One are "virtually identical in their technical specifications," though that's the source's own conclusion rather than a manufacturer statement. The interface has also been compared directly against the Scarlett Solo in at least one YouTube comparison, though no details of that comparison are documented here.
The design brief, as stated in Focusrite's own manual, was to serve "podcasters, vloggers, voiceover artists, streamers, audiobook creators, and more," with an explicit emphasis on users of all experience levels. The Auto Gain and Enhance features exist specifically to deliver "clear and consistent recordings quickly" — a design philosophy that prioritizes speed of setup over depth of control. No production years or release date are documented in the available sources.
Collectibility & Value
The Vocaster One is a current-production interface, not a vintage piece, and there is no meaningful collector market for it. Pricing varies by region and currency: Focusrite's Vocaster range page lists $209.99, though the exact product association of that figure is ambiguous — it appears alongside a bundle description. Retail listings show ₹32,085.00 original / ₹30,480.00 current in India, and R4 650.00 original / R3 560.00 current in South Africa. These are regional prices in different currencies and are not necessarily contradictory.
Warranty coverage is documented as a limited 3-year manufacturer warranty (B&H Photo Video) and a 3-year Thomann warranty, with Thomann also offering a 30-day money-back guarantee and a repair service. No common failures, maintenance requirements, or spare parts availability information is documented for this model.
