A10-TX-US User Guide
System as a camera hop. Select Line in the Selection Menu to accept balanced or unbalanced
line level inputs.
ª To connect balanced microphone or line level sources to the A10-TX-US a cable wired as
described in the specifications or the AC-BALXLR cable is required. This connects the shell
of the LEMO connector to pin-1 of an XLR connector.
Audio Level Control
Input levels are controlled from the Audio Gain option in the Selection Menu. The gain range
available is source-dependent as follows:
• Lavalier setting: 0 dB to 40 dB, 1 dB increments
• Line setting: -10 to 16 dB, 1 dB increments
•
Mic setting (with 20 dB pad): 16 to 40 dB, 1 dB increments
• Mic setting (with no pad): 36 to 60 dB, 1 dB increments
Set input levels so that the limiter is active only on the strongest peaks.
Antenna
The SMA antenna connector is used to mount the included 1/4-wave whip antenna. The use of
any other type is forbidden.
For best operation and transmission power with the included 1/4-wave antenna keep it in the free
field. If worn on a body keep the antenna away from direct contact with the wearer’s body.
Recording
On the A10-TX-US, the record feature is only available for line and mic-level operations. It is
intended for wireless boom and remote microphone locations that do not require a two-wire
lavalier. When the A10-TX-US auto-detects the presence of a lavalier microphone, recording is
disabled.
The A10-TX-US incorporates a data recorder that stores encoded digital waveform and timecode
data in proprietary, data-compressed binary .mic files.
Files recorded on the A10-TX-US are not sound files and require conversion using Audio Ltd’s
Mic2Wav application. (For more information, see “File Conversion .MIC to .WAV” ). After
conversion, a usable 48 kHz digital audio WAV file is made. Files recorded in the A10-TX-US
are approximately 1/3 the size of WAV files generated from corresponding .mic files, saving
valuable space on the microSD card. Files have a maximum duration of six hours. After six hours
the file is automatically split into another recording. Resulting WAV files are sample accurate
across file splits.
To begin recording on the A10-TX-US:
1. Ensure Menu > Audio Setup > Lav/Mic/Line is set to either Mic or Line options.
2. Select Menu > Record/TC > Record.
Recording can also be initiated from the A10-TX Remote App. The default file name of the
.mic file is the serial number of the A10 transmitter; however, the file name may be renamed
via the A10-TX Remote app. For more information, see Remote Control .
A Record “dot” indicator flashes in the display to show that the A10-TX-US is recording. This
indicator is also shown on the A10-RX, when paired with the A10-TX-US, in the TX Data
screen.
