The Synido Live Dock A20 is a compact interface designed for musicians and creators who work on-the-go. At roughly 8x8cm, it’s a pocket-sized audio processor that’s designed for recording onto smaller devices like phones and laptops. The size and simple design make it a great option for live streaming and casual recording, and it comes with a range of useful features for more accurate, high-quality processing.

The A20 is the mid-tier option in Synido’s interface line-up, offering significant upgrades over the Synido Live Dock 10 whilst being more portable and budget-friendly than the A30. The Synido Live Dock 10 is a much simpler adapter for basic recording; the A20 adds dedicated instrument inputs and Bluetooth capabilities. The A30 is more advanced, with physical knobs and a transmitter for a better wireless connection. It has a built-in battery, supports up to 6 hours of continuous use, and can be used while charging. The Live Dock A20 is the most balanced option for mobile-first creators, and it’s a great budget option at only $50. But is it worth it for complex recordings and more advanced setups? This article will look at the features, hardware specs, pros and cons to help you decide if the A20 is the right interface for your setup.

Technical Features and Hardware

The A20 is designed with a selection of inputs and outputs focused on mobile workflows. Despite its size, it includes several dedicated hardware controls for real-time monitoring and high-fidelity audio processing.

> High-Resolution Processing: The unit features a 32-bit DSP dual-core chip that handles all audio processing. It supports studio-standard 24-bit/96kHz resolution, making it usable for more detailed recording. The inbuilt DSP chip means there is very low latency when recording or monitoring, so you won’t be distracted by delays.

> Inputs: The A20 includes a 6.35mm (1/4″) instrument input and a 3.5mm microphone input. This enables you to record both instrument and microphone inputs at the same time, perfect for singer-songwriter style performances with vocals accompanied by a guitar or keyboard. 

> Output: There is only one output, a 3.5mm TRS port for connecting to headphones or a speaker. Both inputs and the output can be gain-staged separately, giving you the ability to hone in the levels for all your devices for a more balanced recording and playback. 

> Dual USB-C and Charging: There are two USB-C ports on the side, one for data transfer and the other for charging your device. This means you can charge your phone whilst recording or streaming, preventing the battery drain that usually limits mobile setups.

> Bluetooth and Loopback: The A20 includes a built-in Bluetooth receiver for additional wireless recording. It also features a Loopback function, which allows you to record or stream the audio coming from your computer/ phone along with your live instrument.

> Class-Compliant Drivers: The A20 is a “plug-and-play” device, which means you don’t need to install drivers or separate software; just plug it in and it’s good to go.

> Mono/Stereo Switch: A simple button allows you to switch between Mono and Stereo recording for the Instrument Input, giving you more options when recording guitars or keyboards.

Testing

When testing the A20 with my mobile setup, I found it more than enough for casual recording and multi-input work. The controls are very simple, and I did miss having preamps with physical knobs, which would’ve made the gain-staging much easier. The lack of XLR input was also noticeable, but I have enough converters to make it work.

However, I enjoyed the versatility of having separate mic, instrument, Bluetooth and Loopback inputs. If I wanted, I could’ve recorded all four inputs at once, making it possible to record or stream a four-track live performance with main vocals, main instrument, drum loop (via Bluetooth on a separate device) and backing instruments (via the Loopback from my DAW). The lack of latency was great for hearing myself in real-time, although the Bluetooth recording did have some pretty noticeable latency that had to be corrected in-DAW. Overall, I’d be happy to use the A20 in my mobile setup again (although it won’t be replacing my studio interface).

 

Pros

Cons
Ultra-Portable: At only 80g and roughly 8x8cm, it is one of the most portable 24-bit interfaces available. Build Quality: The lightweight plastic is designed for portability, but lacks the durability of sturdier interfaces.
High-Quality DSP: The 32-bit internal processing provides a clean signal with very low noise for the price. 3.5mm Mic Input: No XLR input means you can’t use professional studio microphones without using a specialized adapter.
Pass-Through Charging: The ability to keep your phone charged during a live stream is a huge feature for mobile creators. No knobs or faders: Having no physical controls makes gain-staging slow and live adjustments much more difficult.
Loopback and Bluetooth: These features make it a versatile tool for all-in-one recording and streaming.
