A10-TX-US User Guide
ª Remember, for a given channel / sub channel, the actual frequency will change depending on
the TV Channel Mapping setting.
The frequency is displayed with an asterisk (*) when the tune value does not fall within the pre-
allocated sub channel.
See the Frequency Tables in this guide for a complete list of frequencies corresponding to the
channel and sub channel selections.
Modulation
Modulation can be set to Standard (Std) or Long Range (LR) in Menu > Settings > Modulation.
When compared to Standard Modulation, Long Range Modulation has better sensitivity. This
increased sensitivity results in more robust performance in challenging RF environments.
ª The Modulation setting must match between the A10-TX-US and the A10-RX in order for the
transmitted signal to be received.
Audio Input and Control
The A10-TX-US input accepts a wide range of audio input types, including lavalier microphones,
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 lter.
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 lavalier
microphone.
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 signicantly increase battery runtime.
Line-Level Sources
Wireless systems are often used as “camera hop” systems. For most camera hop applications
the output of a eld mixer is connected to a wireless transmitter. The wireless receiver output
is connected to the camera input. The line level input selection simplies using the A10
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 specications 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.
