Introduction Introduction Thank you for purchasing this Audio-Technica product. This PLL synthesized wireless microphone system operates in the UHF band frequency, with two groups of four frequencies. Please read this manual carefully before operating the AT-One system. This manual covers the function and operation of the wireless microphone system.
Receiver Functions Receiver Front: 1. Antenna: Detachable UHF antenna with BNC connector 2. Power Button 3. RF Red LED: Displays the reception status of the RF signal 4. AF Green LED: Displays the reception status of the AF signal 5. UP Channel Button: Tap forward to select an interference free channel 6.
Receiver Functions Receiver Rear: 1. Antenna BNC Receptacle: This provides a connection to the supplied antennas or to coaxial cable used with an antenna divider, antenna booster or remote antennas 2. Balanced XLR Audio Output 3. Unbalanced 1/4” Jack Output 4. Mic/Line Switch: Use this to adjust the audio output of the wireless microphone system for mic level (-20dB) or line-level (0dB) 5.
Transmitter Functions Handheld Transmitter: 1. Power/Mute Button 2. Power/Mute/Battery Status LED Indicates the power/mute/battery level status 3. Channel Selector: Change the channel setting from 11-14 or 21-24 4. Battery Compartment: Insert two AA batteries making sure the polarity is correct 5.
Transmitter Functions Bodypack Transmitter: 1. Antenna 2. Power/Mute Button 3. Power/Mute/Battery Status LED: Indicates the power/mute/battery level status 4. Input Connector: 4-pin locking connector (HRS) 5. Channel Selector: Change the channel setting from 11-14 or 21-24 6. Gain: Rotary control adjusts the sensitivity of the transmitter’s audio to the level of the connected mic or instrument 7. 10dB Switch: Activate this switch to attenuate the signal by an additional 10dB. 8.
Transmitter Functions Power/Battery Status LED: LED Status Green Ready Red Muted Green Flashing On, low battery Red Flashing Muted, low battery No Light No power System Operation System Setup: For best operation the receiver should be at least 1 m above the ground and at least 1m away from a wall or metal surface to minimize reflections. The transmitter should be at least 2m from the receiver, as shown in in the diagram below.
System Operation Connecting the receiver: Plug the DC 12V 500mA power supply into the power connector on the back of the receiver. The power connector is supplied with interchangable UK and EU adaptors. Connect the receiver output to an audio mixer or amplifier input, using a standard audio cable with 3-pin XLR or 6.35mm Jack connectors. Never use balanced and unbalanced audio outputs at the same time, this may cause signal loss or increased noise. Line Mic Set the attenuation for mic or line input.
System Operation Handheld Microphone/Bodypack Transmitter set up: Open the battery cover and insert AA batteries into the battery compartment making sure the polarity is correct. Unscrew the bottom of the handheld mic and open the battery cover to insert AA batteries into the battery compartment, making sure the polarity is correct. Press and hold the power button on the microphone/bodypack transmitter for 4 seconds to turn on.
System Operation Squelch The squelch function is used to adjust the audio output level to suppress the noise levels. If you experience interference in RF spoiled areas (e.g. areas with a lot of mobile phones) or cross talk between transmitters, increase the squelch level until the interference is gone. Please note that increasing the squelch level will decrease the operating range of the system. If the squelch level is high, you may need to move the transmitter closer to the receiver.
System Operation Troubleshooting Problem Solution No Sound - Check the power supply of the transmitter and receiver - Check that the transmitter and receiver are tuned to the same frequency - Check that the receiver is correctly connected to the mixer or amplifier - Check whether the transmitter is too far from the receiver or the Squelch control is set too high - Check for obstuctions between the transmitter and receiver Sound Interference - Check the location of the aerial for obstacles - When using
System Operation Rackmount Setup: To mount the receiver in a 19”standard rack using the included rack kit, attach the L shaped brackets to the opposite end of the unit and mount in the rack unit. To connect two receivers in a 19”standard rack using the optional AT8677 rack kit, attach the short L shaped brackets to the opposite end of each unit, and connect the units together using two metal connecting plates.
