A10-TX-US User Guide
A10-TX-US User Guide
See the
Frequency Tables
in this guide for a complete list of frequencies corresponding to the
channel and sub channel selections.
Audio Input and Control
The A10-TX-US input accepts a wide range of audio input types, including lavalier micro-
phones, balanced microphones, and balanced and unbalanced line level signals. 12 V and 48 V
phantom power is available for balanced microphones. The Selection Menu offers options for
audio level control, input type, limiters, and low cut filter.
Lavalier Microphones
Unbalanced lavalier microphones wired in two-wire mode, are directly compatible with the
A10-TX-US input. When connected, the A10-TX-US auto-detects the presence of a lav mi-
crophone.
Balanced Microphones with Phantom
Balanced microphones, including phantom powered shotgun microphones, can be connected
to the A10-TX-US. 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-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:
• 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, 1 dB increments
Set input levels so that the limiter is active only on the strongest peaks.
Antennas
The SMA antenna connector is used to mount the included 1/4-wave whip antenna. For specialty
applications external, high-gain transmitting antennas can be attached to the SMA connector.
Make certain to connect only passive antennas to the A10-TX-US.
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. When
multiple wireless systems are in use keep transmitters separated by at least 1/2-wave distance of
the transmitted frequency.
Remote Control
The A10-TX can be remotely controlled from an Android or iOS device running the A10-TX
Remote app. The app is available as a free download from the Google Play store and iOS App
store, respectively.
With the A10-TX Remote app, you can:
1 -
Change the transmitter’s name; it is set to
the transmitter’s serial number by default.
2 -
Monitor Sleep status, Battery status, and
