A10-TX-US User Guide
Overview
• Low-noise, studio-grade balanced input for microphones and line level inputs with analogue
limiter and 48 V phantom power.
• State-of-the-art 100% digital long-range modulation delivers the longest transmission
distance of any system on the market.
• Standard and long-range modulations offer full bandwidth (10 Hz – 20 kHz), ultra-low
distortion, and high dynamic range.
• Built-in Bluetooth® to remotely control the A10-TX-US from an Android or iOS device
using the A10-TX-US Remote app.
• Powered by two AA (LR6) batteries.
Digital wireless for today and tomorrow.
The A10 Digital Wireless System is designed for the technical demands and requirements of
today’s RF-hostile, multi-channel productions. The A10-TX-US and A20-Mini digital transmitter
and A10-RX two channel receiver deliver broadcast-quality audio and reliable digital RF
performance with an easy, multi-system setup.
The A10’s proprietary digital RF topology and Advanced Digital Diversity System is the result of
years of research, laboratory experimentation, and customer experience. The result is a wireless
link with full 20 kHz audio bandwidth, high dynamic range, ultra-low distortion, an extremely
low 2 millisecond end-to-end delay in Standard modulation. The A10 System allows the user to
operate up to 20 channels in an 8 MHz TV channel, maximizing spectrum efciency.
With rmware version 5.00, the A10/A20 Wireless System delivers the longest transmission
distance of any system on the market.¹ The state-of-the-art, 100% digital long-range modulation
offers the same great audio quality (10 Hz – 20 kHz) as our Standard modulation scheme with a
longer range for both line-of-sight and heavy multipath transmission.
The core of the A10-TX-US transmitter is its low-noise, high-dynamic-range analog input. It
accepts signals from low-level lavalier microphones to balanced line-level. The 3-pin LEMO
input offers analogue limiters, 5 volt bias for lavalier microphones, as well as 12 and 48 volt
phantom power for balanced microphones.
The wireless boom has become a requirement for many productions. The A10-TX-US is the
rst digital wireless transmitter that accepts either lavalier microphones or a phantom-powered
balanced microphones. With the A10-TX-US mounted on the boom pole a user gains numerous
advantages, including:
• 1/4-wave antenna in free-space for maximum RF radiating efciency,
• The exibility to mount the transmitter at the top, bottom, or clipped to a boom operator’s
belt,
• A true balanced input with superior noise rejection and immunity to induced RF interference,
• Integrated digital recorder with precision timecode generator (for Mic / Line-level
operations),
• Convenient Bluetooth control,
• Built-in 12 or 48 V phantom power with a full 10 mA supply,
• One unit which accepts lavaliers, balanced microphones, and line-level camera hop signals.
