I dont think it have one / or lets say i have never looked for one.
The vantrue.us website is lagging behind their other website vantrue.net. I downloaded the EBG311 firmware from the vantrue.net website.I couldn’t find the new firmware this morning but. All I saw on the Vantrue site was the update from 7/27
I checked this part, it is a false panel without holes, and it was probably not bad make holes for ventilation too.In the upper part of the cooling radiator, a Wi-Fi module plate is glued inside, it can significantly block the ventilation inside the case.
I have no idea exactly what is meant by having an "optimized microphone". That could be a different microphone or placing the current microphone in a different location.Awww man, what a bummer.
I guess the good news is, it will at least get fixed in future production units.
I'm one of those people that believes audio quality is truly 50% of the game, and just as important as video quality.
In movies, youtube videos, dash cam footage, just about everything.
I'd even be willing to take apart my A119 Mini, and replace the microphone with new optimized one if it becomes available.
Is is OK to complain about a "free item" I received. lol
Both of the Vantrue E1 test units I've tested have a VERY LOUD audio volume. The recording level at times is so high it can clip the audio. Most of the audio is just MUCH LOUDER than other dash cameras. The A119 Mini's audio volume is at a whisper level (except for the announcements from the A119 Mini) while the Vantrue E1's audio volume is like someone shouting through a megaphone. The audio volume for VIOFO A229 Duo and VIOFO T130-3CH are "just right".That remimds me I need to test the audio on the Vantrue E1.
I haven't gathered any on road test footage yet.
I'm still testing its functionality, and what not.
From the FCC pictures it looks like the microphone is mounted on the case on the left side (looking from the back of the camera). The second arrow points to the M+/M- connection points on the circuit board.
The A119 Mini's audio volume is at a whisper level (except for the announcements from the A119 Mini)
If I recall correctly, the early units had the mic taped to the capacitors. They eventually moved it to the side, taped in front of the vents. Seems that's were it is on the Mini now, so I'm surprised it's that low.When first introduced the A119 V3 had the same issue, although I wouldn't quite characterized it as a whisper the audio level was way too low. I experienced it with two early units. The issue was eventually remedied with a firmware update.
Here's the info from my 2-Aug-2022 post about the audio levels for the Vantrue E1, VIOFO A119 Mini, VIOFO A229 Duo and VIOFO T130-3CH.Internal Microphone Audio Level Test
In my Vantrue E1 dash camera thread, I posted a link to a YouTube video with some sample video footage and a quick audio test of four dash cameras (Vantrue E1, VIOFO A119 Mini, VIOFO A229 Duo, VIOFO T130). The A119 Mini audio was at a very low volume. The Vantrue E1 was at a very high volume (almost to the point of being clipped).
My Vantrue E1 - Audio Level Post
Audio Test 2
I uploaded audio from Epidemic Sound music subscription to my iPhone. This is audio I can use in my YouTube videos to avoid a copyright claim on my videos. I had the dash cameras operating in normal mode and while vehicle was stationary (in my garage and with the HVAC blow motor off), I played one of the Epidemic Sound sound tracks over my car's audio system. I set the audio level output from the car radio (Chevy MyLink radio head unit) to a level of 13 (not super quiet, not ear drum piercing, at a normal listening level).
I downloaded the video files from all four dash cameras and imported them into Adobe Premiere Pro so I could examine the mono audio tracks created by each dash camera.
Here are the status lines from all four cameras showing their time clock values are within 2 seconds of other dash cameras in the test.

The next two screen shots are of the four audio tracks dB levels (1st pic = full sample, 2nd pic = one example of one of the peaks).

The Vantrue E1 has firmware VT-EBG311 that was released on 01-Aug-2022. The VIOFO A119 Mini is running a test firmware version of V1.0_0714 which was to have optimized the audio recording level. The A119 Mini's audio level is very low. The A119 Mini's recording level is actually an improvement over the V1.0_0621 firmware, but nowhere near where it needs to be for the dash camera. The VIOFO A229 Duo and VIOFO T130 have very similar audio recording levels.
The audio levels shown in the second pic show a wide variance in the audio track dB levels.
-10.7 dB - Vantrue E1
-37.9 dB - VIOFO A119 Mini
-22.9 dB - VIOFO A229 Duo Front
-21.3 dB - VIOFO T130-3ch Front
Audio Test Results - In My Opinion
Vantrue E1 - Volume is too loud
VIOFO A119 Mini - Volume is well below where it needs to be
VIOFO A229 Duo - Volume is "just right".
VIOFO T130 - Volume is "just right".
I've reported my findings to both Vantrue and VIOFO.
The A119 Mini's audio level has been an issue from day 1 of testing. I was given a test firmware V1.0_0714 which optimized the audio level in the firmware and it did slightly increase the audio level from almost impossible to hear to what I'm calling "a whisper" level. The A119 Mini's audio level is 15 to 16 decibels below the levels of the A229 Duo and T130 audio.When first introduced the A119 V3 had the same issue, although I wouldn't quite characterized it as a whisper the audio level was way too low. I experienced it with two early units. The issue was eventually remedied with a firmware update.
