There are two models of the A10-TX-US transmitter to cover this frequency range. Multiple A10 Digital Wireless systems can be used simultaneously on nearby adjacent frequencies without worry of intermodulation interference since the A10 Digital Wireless System and its digital RF transmission is inherently immune to intermodulation. Systems can be used together when separated by at least 400 kHz. Use the scan tool on the A10-RX receiver to search for available frequencies. ª When using A10 Digital Wireless systems in conjunction with analogue RF systems, an intermodulation plan needs to be addressed for analogue receivers. Channel, Sub Channel, Frequency To simplify frequency selection, frequencies are divided into channels and sub channels. · Channel - corresponds to broadcast television channels used in geographic region. · Sub Channel - channels are divided in 400 kHz increments called sub channels to speed up frequency selection. The number of sub channels depends on the channel mapping selected. · Tune - specific frequencies within the transmitter's tuning range can be selected in 25 kHz increments. To change TV channels, use the Left button to highlight the TV Channel. Press the centre Menu button to select the TV channel. Select the sub channel until the desired sub-channel is selected. - 10 - 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 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 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 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 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 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. Mute Button When the Mute Button function is enabled, holding the Left button for 1 second toggles Mute on or off. While Muted, the transmitter LED flashes red. The paired Receiver channel display Muted on the channel screens. Audio is muted at the transmitter input, this means both recorded and transmitted audio will be silent.

The use of any other type is forbidden. - 11 - A10-TX-US User Guide 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. File Storage Proprietary MIC files generated by the A10-TX-US are stored on FAT32-formatted microSD cards. The microSD card slot is located in the battery compartment and is accessed by removing the battery nearest the display. If no microSD card is inserted in the unit, a `No card detected' message is indicated. New cards, or cards with material that can be overwritten, can be formatted in the A10-TX-US. ª Formatting deletes all existing recordings present on the card. There is no provision to manage files from the A10-TX-US. File management, including file renaming and individual file deletion, is done when the microSD card is mounted to a computer via a card reader. File Conversion MIC to WAV The MIC files generated directly on the A10-TX-US are not usable until converted. Audio Ltd. provides a free Mic2Wav conversion utility, available for download from the Audio Ltd. website: www.audioltd.com. This utility--available for Mac or Windows operating systems--converts MIC files to usable Broadcast WAV files. ª Mac operating systems need to be in 24-hour time to correctly reflect timecode values. Enter macOS System Preferences (/Language & Region/Time format) and change to 24 hour format. - 12 - A10-TX-US User Guide Timecode and Time-of-Day Clocks The A10-TX-US includes high-precision internal clocks to maintain time-of-day/date and SMPTE timecode. These clocks run continuously when AA batteries are in the unit and draw negligible current (less than 1 uA). The A10-TX-US design incorporates a supercapacitor to power the time-of-day clock for several days in the absence of batteries. The supercapacitor reaches full charge when batteries have been in the unit for five minutes. Time-of-Day Clock The time and date clock holds time and date for files recorded on the A10-TX-US, and can be used for the Time of Day timecode value. To set time and date: 1. Enter the Selection Menu option real time clock. (Menu > System > Set Time/Date) 2. Use the center Menu button to move between year, month, day, hours, and minutes. Use the Left and Right buttons to change the values. 3. Press the center Menu button to select the Return arrow and view current values. Press again to exit. External LTC Jamming External LTC timecode can be applied to the A10-TX-US to synchronize its internal timecode clock. Synchronization of timecode clocks is called "jam syncing". To jam the A10-TX-US timecode clock, navigate to Menu > Record/TC > Timecode in the Selection menu. Connect an LTC timecode source to the 3-pin LEMOTM input connector using either the AC-TCLEMO or AC-TCBNC-IN cables. The A10-TX-US will jam its timecode clock from the incoming timecode signal. ª While in the Timecode menu, RF transmission and recording are deactivated on the A10-TX-US. The timecode clock remains accurate when the transmitter is powered or in standby mode. When the unit is powered down accurate timecode is held for six hours. After six hours the timecode clock is reset to its default value. Timecode Output The transmitter's 3-pin LEMO connector also functions as a timecode output connection. In the Selection menu navigate to Menu > Record/TC > Timecode. While in this screen, timecode can be sent out of the A10-TX-US using the AC-TCLEMO or AC-TCBNC-OUT cables. Upon exiting the Timecode screen, the 3-pin LEMO reverts back to the selected lavalier, microphone, or line input. RF transmission is reactivated, and recording is available for mic or line inputs. - 13 - A10-TX-US User Guide Remote Control The A10-TX-US 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.

Maintain close proximity to the transmitter for reliable connection. User Groups The User Groups feature allows for the easy, intuitive naming of specific frequencies for each A10 transmitter used on set, and grouped together for faster tuning. The operator of an A10 receiver may then easily switch between transmitters by choosing alphanumeric names, such as "Jack" and "Jill", instead of having to remember and manually tune to different, specific numerical frequencies. For instance, a producer or director may want to monitor several different actors' wireless transmitters. Rather than having to keep a list of all of their frequencies, each transmitter may be - 15 - A10-TX-US User Guide pre-assigned a frequency and given an actor's name. Then only those pre-assigned frequencies that have been named will be available as possible options for tuning. User groups are created in Mic2Wav--a utility application available as a free download from the Audio Ltd. website to Mac or Windows-based computers--and then uploaded, as ALUG files, to A10 transmitters and receivers. To create a new user group: 1. Open Mic2Wav on your computer. 2. Do one of the following: · On a Mac, select User Group File > New. · On a PC, select File > User Groups > Create a new file. 3. Name the new group. 4. Select a range of frequencies via the Band drop-down list. Options include A, B, C, D and Any. This will automatically restrict users in the group to the frequencies within that band. Selecting Any will make frequencies within all bands available for assignment to users in the group. ª All A10-TX will have the available bands listed on the printed label inside the battery compartment door as well as displaying the frequencies capable of being generated by the transmitter in Menu > System > Info. 5. Select OK. The User Group Editor screen appears with fields for the first user (U1) available. 6. Enter a Name and Frequency for U1 in the fields provided. The A10-TX transmitter's serial number is optional. Entry of ineligible frequencies (or characters) will cause the text in the field to appear red. Mic2Wav will automatically fills in .000 as the subchannel variable for frequencies entered as a whole number. Mic2Wav automatically follows the best-practice method of spacing adjacent transmitters by at least one subchannel, preventing possible interference from other transmitters. 7. Click Add (on a PC) --or the Plus (+) button on a Mac-- to add the user to the group. This also adds a new line for the next user (U2, U3, etc).
