Personal Experience with the Audio A10 System

I first purchased the A10s brand new, shortly after they were released in 2019. I got the dual receiver and 2x A10 transmitters along with the cables required to power the receiver in my sound bag and an adapter and cable for using an A10 on a boom. I also purchased some DPA adaptors for my lavalier microphones so I could continue to use my DPA 4071 microphones with the new A10 transmitters.

Overall, I’ve been fairly satisfied with the A10 system, being impressed with the various features it offers, but there have also been some struggles with the system too along the way which I will get into in the blog. The A10 system has since gone on to be succeeded by a new model, the A20, now under the umbrella of the Sound Devices brand. However, it doesn’t take away from the fact that the A10s are a fantastic piece of kit, so let’s get into the features of the system!

  1. Power Consumption and Heat Generation: One downside of the A10 Radios is the power-hungry nature of the dual receiver unit, which can lead to excessive heat generation in the sound bag, potentially impacting performance and longevity.

  2. Signal Range Variability: While the A10 Radios offer impressive signal range in optimal conditions, some users have reported inconsistency, with signal strength varying unpredictably, even at short distances.

  3. Monitoring Limitations: Despite the capability for local recording, the inability to monitor audio directly from the microSD card is a drawback, limiting real-time feedback during recording sessions. However, this is a frequent occurance in most transmitters which offer a local recording feature.

  4. Subpar Mobile App: The A10 Radios' mobile app, while offering remote operation features, suffers from poor Bluetooth connectivity and usability issues, detracting from its overall effectiveness.
