AirLine Micro Camera SystemOwners Manual 1IntroductionThank you for purchasing the Samson AirLine Micro Camera wireless system, a breakthrough in wireless microphone technology. It is perfectly suited for commercial videographers, corporate, as well as broadcast video professionals. The AirLine Micro utilizes the latest in miniaturized electronic components, as well as lithium-ion batteries, resulting in Samson’s smallest wireless system, while preserving the high-quality audio you expect from a Samson wireless device. The AirLine Micro system ensures clear, interruption-free perfor-mance by combining tone-key with auto-mute. This configuration allows only the transmitter’s audio to pass through the receiver, and mutes the output if there is any interference.The AirLine Micro Camera system is designed so that it can easily be integrated into your current video system, and comes with all of the necessary components to execute your video shoot or live broadcast. The system is comprised of one AL2 belt pack transmitter and one AR2 micro receiver, which are each housed in a durable aluminum chassis. The AR2 micro receiver features an 1/8” unbal-anced audio output, with microphone or line level output, USB DC-input, and RF and Battery LED indicators. The system also includes a mounting adaptor that fits into the standard hot shoe, enabling it to be attached to any video camera. The system also includes one 3.5mm-3.5mm and one 3.5mm-XLR audio cable to connect to the audio input of your camera. Also included is an LM10 omni direc-tional lavaliere microphone that allows the performer the freedom to move around while maintaining outstanding audio clarity. The AirLine Micro system utilizes fully rechargeable lithium-ion battery technology. The included AL2 transmitter and AR2 receiver feature internal rechargeable batteries, each allowing 10 hours of battery operation. Both the AL2 and AR2 can be recharged with the included AC adaptor and USB Y-cable, or with the included AR2DT docking station, or by USB bus power when connected to any USB host-equipped device. The AR2 can alternatively be powered by the included AC adaptor, for continuous operation.
AirLine Micro Camera System2IntroductionIn this manual, you’ll find a detailed description of the features of your AirLine Micro Camera system, as well as a guided tour of its components, step-by-step instructions for setting up and using your system, and full specifications. If your AirLine Micro Camera system was purchased in the United States, you’ll also find a warranty card enclosed. Don’t forget to fill it out and mail it! This will enable you to receive online technical support, and will allow us to send you updated information about this and other Samson products. If your Airline Micro Camera system was purchased outside of the U.S., contact your local distributor for warranty details. Also, be sure to visit our website (http://www.samsontech.com) for information about our full product line.Special Note for U.S. Purchasers: Should your Airline Micro Camera system ever require servicing, a Return Authorization (RA) number is necessary. Without this number, the unit will not be accepted for return. If your AirLine Micro Camera system was purchased in the United States, please call Samson at 1-800-372-6766 for an RA number prior to shipping your system. If possible, return the unit in its original carton and packing materials. If your AirLine Micro Camera system was purchased outside of the U.S., contact your local dis-tributor for service information.Battery Notice: Lithium-ion batteries are low-maintenance, and provide increased power capabilities in a lighter package, compared with NiCad (nickel-cadmium) batteries. All lithium-ion batteries have a finite number of times that they can be recharged, called a charge cycle. A charge cycle means using all of a battery’s power, but does not necessarily mean a single charge. A lithium-ion battery can be recharged when needed, and does not need to be fully discharged (contrasted with a NiCad battery) before charging again. Repetitive full discharges of the battery should be avoided, as lithium-ion batteries need to be utilized continuously for maximum life and performance. If you are not using your wireless system often, be sure to complete a full charge cycle at least every three months. If you need to replace your AL2 or AR2 battery, please contact Samson, or your local distributor.

AirLine Micro Camera System4Quick StartPlease follow these basic procedures for setting up and using your AirLine Micro:1. For your AirLine Micro system to work properly, both the receiver and transmitter must be on the same channel. Remove all packing materials (save them in case your unit needs to be serviced in the future) and check to make sure that the supplied receiver and transmitter are on the same channel. Note: The channel number is laser-engraved on the back of the AR2 and AL2 chassis. If these channels do not match, please contact Sam-son Technical Support at 1-800-372-6766. If your unit was purchased outside of the U.S., please contact your local distributor.2. Before using your AirLine Micro system you should fully recharge the transmitter and receiver batteries. Plug the AC adaptor into a power socket. Connect the USB Y-Cable into the USB socket on the AC adaptor. Plug the two mini-USB connectors into the USB ports on the AL2 transmitter and AR2 receiver. When the transmitter and receiver are completely charged, the BLUE LED indicator will turn off. 3. Remove the USB cable and continue with setup. 4. Physically place the receiver where it will be used (if desired, the AR2 receiver model can be used with the included AR2DT dock) and fully extend the antennas.5. Turn your audio system off and connect the receiver’s 1/8” unbalanced output jack to the microphone or line level audio input of your video camera, amplifier or mixer. Set the AR2 Mic/Line Level switch to match the input. 6. Turn on the receiver using the Power Switch. When on, the Status Indicator will be steady YELLOW.
AirLine Micro Camera SystemOwners Manual 5Quick Start7. Turn on your AL2 transmitter by pressing and holding the Multi-Function Switch, until the Status Indicator LED flashes GREEN; then release it. The AL2 Status Indicator will now light steady GREEN. The AR2 receiver Status Indicator will change from YELLOW to GREEN, indicating that it is receiving a valid RF signal.8. Position the LM10 lavaliere microphone onto your lapel, as close to your mouth as possible but off to one side (to prevent a nasal sound) and be sure the mic is unobstructed by clothing. Bear in mind that omnidirectional microphones (mics which pick up signal from all directions) are more prone to feedback problems than unidirectional (cardioid or hypercardioid) microphones. In general, you can avoid feedback by taking care not to use any microphone directly in front of a PA speaker (if this is unavoidable, try using an equalizer to attenuate high- or mid-range frequencies which cause the feedback “squealing”).9. Turn on your connected amplifier and/or mixer, but keep its volume all the way down. Make sure the AL2 transmitter is not muted. Note: If the AL2 is muted, the AL2 Status Indicator LED will flash GREEN and the AR2 Status Indicator will flash GREEN. To un-mute the AL2, press the Multi-Function Switch and the Status Indicator will light steady GREEN. 10. Speak or sing into the microphone at a normal performance level while slowly raising the audio input control of your amplifier or mixer, until the desired volume is reached.11. If you hear distortion at the desired volume level, determine if the Status Indicator LED on the receiver is lighting RED. If the Status Indicator is RED, simply move the microphone further from your mouth. If the Status Indicator is lighting GREEN, make sure that the gain structure of your audio system is set correctly (consult the owners manual of your mixer and/or amplifier for details).
AirLine Micro Camera System6Quick StartIf you hear a weak, noisy signal at the desired volume level, make sure that the gain structure of your audio system and the Audio Output Level switch are set correctly. If the Audio Output Level switch is set correctly and the signal coming from the receiver is still weak and/or noisy, simply position the microphone closer to your mouth. If you feel that the level of the microphone needs further adjustment, press and hold the AL2 Multi-Function Switch while the unit is powered on until the Status Indicator turns off; then release the switch. Press and hold the Multi-Function Switch again for five sec-onds. The AL2 Status Indicator will first flash GREEN, then flash YELLOW, to show that you are in Volume Adjustment mode. Press and release the Multi-Function Switch once, and the microphone volume will increase one level. To continue to adjust the microphone volume, continue to press and release the Multi-Function Switch. There are five levels. With each increasing level, the Status Indica-tor will flash faster. After level five is reached, the transmitter will cycle back down through the levels each time the Multi-Function Switch is pressed. As the levels decrease, the Status Indicator flashes slower. When the desired level is reached, release the Multi-Function Switch. The AL2 will return to normal operation after 10 seconds, and the Status Indicator will light steady GREEN.12. Do a walk-around through the intended area of coverage while observing the AR2’s Status Indicator; it should stay steadily GREEN, indicating sufficient RF reception in all areas of intended use. If the AR2’s Status Indicator lights YELLOW, it signals RF dropout (or the receiver may be muted). Reposition the device (or its antennas) as necessary. If extended range coverage is required, another AR2 true diversity receiver (set to the same channel as the transmitter) should be used.13. If you have followed all of the above the steps and are still experiencing difficulties with your system, please call Samson Technical Support (1-800-372-6766) between 9:00 a.m. and 5:00 p.m. EST. If you purchased your system outside of the U.S., please contact your local distributor.
