The Earthworks M30 G2 microphones will fully replace M30 models in July 2026. This change comes as a result of the manufacturer phasing out the M30 in favor of the M30 G2. Telestra Level D customers who have previously purchased the M30 microphone as part of the ASTi Level D hardware kit (PN: CH-LVLD) will receive the M30 G2 in the event of a refresh.
Significant differences between the models are as follows:
| M30 | M30 G2 | |
|---|---|---|
| Length | 9.5" | 8" |
| Frequency Response | 3 Hz–30 Hz | 5 Hz–30k Hz (±1 dB) |
| Sensitivity | 34 mV/Pa | 10 mV/Pa |
| Phantom Power Requirements | 24 V–48 V | 12 V–48 V |
| Weight | 0.5 lbs | 0.3 lbs |
M30 G2 packaging differs from M30 packaging to account for the length difference between the models. Don’t be alarmed if you receive hardware in packaging that doesn’t match what was shown at purchase.
To properly configure the M30 G2 for an ACU2 channel, set the input gain for the corresponding channel to +2 dB (M30) or +12 dB (M30 G2). You can adjust the input gain from the Telestra web interface under Network Devices > Hardware > ACU2s. Ensure the ACU2 and corresponding channel settings you’re modifying on the Telestra web interface match the ACU2 and corresponding channel to which you've connected the microphone. Go to “Network Devices” in the Telestra Web Interface User Guide for further information about modifying ACU2 channel input gain.
The position of the microphone in the simulator must precisely match the position used in the aircraft, as documented in the aircraft data package. Specifically, microphone tip positioning is crucial for replicating audio results. Ensure the length difference between the M30 and M30 G2 is accounted for when adjusting microphone configuration within the simulator.
