Attenuation Pad Digital Audio Coax Baluns Series (Front View) (Back View) Multi-Circuit BNC to XLR Digital Audio AES Balun Inline Baluns UniPatch System fully loaded with 16 AES Baluns for 64 110-75 Ohm circuits (allows modules to be mounted either way) ADC proudly offers a full series of precision Balun products: three XLR to BNC Inline Baluns; ® plus numerous Multi-Circuit Baluns that can be used in our UniPatch system or in throwdown applications. For over 50 years ADC has been the leader in audio and video patching products with unsurpassed quality, reliability and innovation. To complement its full line of connectors, ADC has introduced a series of 110 Ω to 75 Ω AES impedance matching Baluns. By converting balanced signal over twisted pair cable to unbalanced signal over coax, the Audio Coax Balun permits the extension of digital audio signal transmission distances. Twisted Pair (Balanced) Connector Application BNC Connects, extends and lengthens digital audio cable runs by converting twisted pair to coax. 75 to 110 XLR E3 Transformer QCP Series Features Balun Circuitry • Signal distribution to use with video patch panels, routers and VDAs Twisted Pair (Balanced) Connector • Permits longer cable runs over coax BNC • SMPTE 276M & AES3 Transmission Standards • Capable of carrying 2 channels AES/EBU 75 to 110 XLR Transformer E3 digital audio over coax QCP Balun Circuitry with Attenuation Pad 3.09” 78.4 mm w w w . a d c . c o m • + 1 - 9 5 2 - 9 3 8 - 8 0 8 0 • 1 - 8 0 0 - 3 6 6 - 3 8 9 1 0.75” 18.9 mm Spec Sheet Digital Audio Coax Baluns Series Inline XLR to BNC Baluns Features • Digital Audio Impedance Matching • Precision machined robust body and connectors BNC to XLR Inline Baluns Specifications ELECtRICAL Operating Range: .1-6 MHz Maximum Voltage: 5 Vpp Return Loss: Better than 23 dB Insertion Loss: Better than .26 dB MAtERIAL Precision machined brass bodies ENVIRONMENtAL Tested to IEC68, MIL-STD-202 85.5 mm (3.37”) 78.4 mm (3.09”) 18.9 mm (0.75”) 18.9 mm 85.5 mm (0.75”) (3.37”) 18.9 mm (0.75”) O r d e r i n g I n f o r m a t i o n Description Catalog Number Inline Baluns, twisted Pair-Coax, 110 Ω – 75 Ω Inline Male XLR to BNC Balun BAL-XLR-BNC-M Inline Female XLR to BNC Balun BAL-XLR-BNC-F Inline Female XLR to BNC Balun with 10 dB Attenuation BAL-XLR-1VBNC-F w w w . a d c . c o m • + 1 - 9 5 2 - 9 3 8 - 8 0 8 0 • 1 - 8 0 0 - 3 6 6 - 3 8 9 1 2 1 0 / 0 6 • 1 0 3 4 1 3 A E Digital Audio Coax Digital Audio Coax Baluns Series ® UniPatch Multi-Circuit Baluns AES 110 Ohm to Precision transformers, AES 110 Ohm to 75 Ohm Balun glass epoxy circuit board, 75 Ohm Balun (E3) true 75 Ohm BNC connectors (QCP) Features • Uses E3 or QCP punchdown connectors • Digital Audio Impedance Matching • Can be mounted in the standard UniPatch • Unique removable attenuation pad capability frame or used in a throwdown application allows users to control individual circuit’s voltage outputs • Uses precision BNC connectors Specifications ELECtRICAL Operating Range: .1-6 MHz Maximum Voltage: Variable Return Loss: Better than 28.5 dB 10 Input Insertion Loss: Better than .14 dB Voltage 9 2 volts 3 volts 8 4 volts ENVIRONMENtAL 5 volts 7 6 volts Tested to IEC68, MIL-STD-202 7 volts 6 8 volts 9 volts 5 10 volts 4 3 2 1 0 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 Attenuation Pad Value (dB) Pad any of 4 circuits from 0-20 dB with removable attenuation pad values O r d e r i n g I n f o r m a t i o n Description Catalog Number UniPatch Multi-Circuit Balun, AES Audio to Coax , 110 Ω – 75 Ω UniPatch E3 to BNC 4-Circuit Balun AM-411075-E3 UniPatch QCP MKII to BNC 4-Circuit Balun AM-411075-MKII w w w . a d c . c o m • + 1 - 9 5 2 - 9 3 8 - 8 0 8 0 • 1 - 8 0 0 - 3 6 6 - 3 8 9 1 3 1 0 / 0 6 • 1 0 3 4 1 3 A E Digital Audio Coax Output Voltage (p-p) Digital Audio Coax Baluns Series ® UniPatch Multi-Circuit Balun/Audio Splitter Features • Digital Audio Impedance Matching • Can be mounted in the standard UniPatch frame or used in a throwdown application • Unique removable attenuation pad capability allows users to control individual circuit’s voltage outputs • Cost efficient splitting done passively without need for active equipment • Uses E3 or QCP punchdown connectors • Uses precision BNC connectors AES 2:4 Splitter Balun Specifications ELECtRICAL Operating Range: .1-6 MHz Maximum Voltage: Variable Return Loss: Better than 25 dB Insertion Loss: Better than .2 dB ENVIRONMENtAL Tested to IEC68, MIL-STD-202 O r d e r i n g I n f o r m a t i o n Description Catalog Number UniPatch Multi-Circuit Balun/Audio Splitter, 110 Ω - 75 Ω Split 2-Circuit Input Audio (QCP) into 4-Circuit Output Coax (BNC) AM-2110-475-MKII Split 2-Circuit Input Audio (3-Pin) into 4-Circuit Output Coax (BNC) AM-2110-475-E3 w w w . a d c . c o m • + 1 - 9 5 2 - 9 3 8 - 8 0 8 0 • 1 - 8 0 0 - 3 6 6 - 3 8 9 1  1 0 / 0 6 • 1 0 3 4 1 3 A E Digital Audio Coax Digital Audio Coax Baluns Series ® UniPatch Multi-Circuit Front Facing Balun Features • Digital Audio Impedance Matching • Can be mounted in the standard UniPatch frame or used in a throwdown application • Uses E3 connectors • Uses precision BNC connectors • Full front access Specifications ELECtRICAL Multi-Circuit Operating Range: .1-6 MHz Front Facing Balun Return Loss: Better than 28.5 dB Insertion Loss: Better than .14 dB ENVIRONMENtAL Tested to IEC68, MIL-STD-202 -20 -25 -30 -35 -40 -45 -50 0 1 2 3 4 5 6 7 8 9 10 Frequency (MHz) Return Loss O r d e r i n g I n f o r m a t i o n Description Catalog Number UniPatch Multi-Circuit Front Facing Balun, AES Audio to Coax , 110 Ω – 75 Ω UniPatch E3 to BNC Front Facing Balun AM-411075-E3-FF Web Site: www.adc.com From North America, Call Toll Free: 1-800-366-3891 • Outside of North America: +1-952-938-8080 Fax: +1-952-917-3237 • For a listing of ADC’s global sales office locations, please refer to our Web site.
