Balanced Microphones with Phantom
Balanced microphones, including phantom powered shotgun microphones, can be connected
to the A10-TX. 12 V and 48 V phantom power are available for microphones requiring it. For
microphones that can properly operate on 12 V phantom, such as the Schoeps CMIT, select 12
V phantom to significantly increase battery runtime.
Line-Level Sources
Wireless systems are often used as “camera hop” systems. For most camera hop applications
the output of a field mixer is connected to a wireless transmitter. The wireless receiver output
is connected to the camera input. The line level input selection simplifies using the A10 Sys
-
tem 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, 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:
•
Lav 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
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
The A10-TX 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 are not
sound files and require conversion using Audio Ltd’s Mic2Wav application. (For more informa
-
tion, see
). After conversion, a usable 48 kHz digital audio WAV
file is made. Files recorded in the A10-TX are approximately 1/3 the size of WAV files generated
from corresponding .mic files, saving valuable space on the microSD card. Files have a maxi
-
mum 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:
»
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
.
An indicator flashes in the display to show that the A10-TX is recording. This indicator is also
shown on the A10-RX, in the TX data screen, accessed by pressing the Right button on the
A10-RX receiver.
