Designed as a successor to the IFBT4, the IFBT20 offers two transmitter channels, enhanced connectivity, updated interface, new form factor, and convenience features to the IFB product family. It has been designed to work with the new IFBR1B and IFBR1C receivers and is ideal for Broadcast TV News & Production, Location Sound, and backstage communication. The IFBT20 is also an ideal transmit base station for Point-to-Point audio using the full-fidelity Digital Hybrid Wireless mode and compatible receivers.The IFBT20 includes a USB-C port for firmware updates and an IR port for fast setup with compatible receivers. A large, high resolution, backlit LCD and tactile push buttons provide an intuitive interface that is highly visible in daylight or dimly lit conditions.The half-rack transmitter provides two audio inputs which can be individually configured to be analog or digital. The input connectors are full size XLR/TRS combo types for balanced mic, line level analog or AES3 signals, and are protected from DC on the signal lines.Input preamp circuits use a special balanced amplifier with very high common mode rejection to minimize hum and noise. The modulated RF signal is filtered before and after amplification to suppress out-of-band noise and spurious signals. Dante inputs are included for installations with audio over IP.The system is designed and developed with the rugged, durable packaging youve come to rely on. The transmitter chassis is all-metal. The front panel is an aluminum extrusion with a durable powder coat finish.The IFBT20 half-rack transmitter features user-selectable transmission power to cover a wide varity of applications. Firmware updates are made via the USB-C port on the front panel of the housing via Wireless Designer software. The procedure is very simple using a standard USB-C cable connected to a Mac or PC.Setup and adjustment are enabled through a backlit LCD, tactile buttons and an intuitive menu structure. Input gain is adjustable over a wide range in 1 dB steps to optimize modulation and limiting for maximum signal to noise ratio and minimum distortion.Band A1: 470.100 537.575 MHzMain Features:IFB and Point-to-Point applications2 independent audio transmissions per 1/2 RU enclosureDigital Hybrid Wireless and IFB compatibility modesUSB-C port for firmware updatesDante compatibleIR (infrared) port for fast setup with compatible receiversUser-selectable RF carrier per channelDurable aluminum housingInput configurations for Mic, Line, ClearCom, RTS1, RTS2, and AES digitalUSB-C and Ethernet data connectionsCompatible with Wireless Designer SoftwareSpecifications:RF Power Output:- Two carriers; one audio channel each- IFBT20: Power adjustable on each carrier to 10, 25, 50, 100 or 250mW- IFBT20/E01: Power adjustable on each carrier to 10, 25 or 50mWAntenna Output: 2 x BNC jacksOperating Frequencies:- IFBT20 Band A1: 470.100 537.575 MHz- Band B1: 537.600 607.950 MHz- IFBT20/E01 Band A1: 470.100 537.575 MHz- Band B1: 537.600 614.375 MHz- Band C1: 614.400 691.175 MHz- NOTE: Its the users responsibility to select the approved frequencies for the region where the transmitter is operatingFrequency Selection Steps: 25 kHzFrequency Stability: 0.002%Modulation: FMEmission Designator: 110KF3ESpurious Radiation: Compliant with ETSI EN 300 422-1Equivalent Input Noise: 128 dBVLatency:- Digital Source: 2.3 mS to analog receivers (IFBR1B, IFBR1C)- 3.6 mS to digital receiver in IFB mode (M2Ra)- 3.6 mS to Hybrid receiver in NU Hybr mode (Venue 2, LR)- Analog Source: 1.2 mS to analog receivers (IFBR1B, IFBR1C)- 2.5 mS to digital receiver in IFB mode (M2Ra)- 2.6 mS to Hybrid receiver in NU Hybr mode (Venue 2, LR)Audio Frequency Response:- IFB mode: 100 Hz 8 kHz, 1 dB- NU/EU Hybrid Mode: 40 Hz 20 kHz, 1 dBAudio Input Levels:- 0 dBu for Line, RTS1 & RTS- -10 dBu for ClearCom- -42 dBu for mic dry inputs (no phanton power)- +/- 50VDC maxAudio Input Config: Balanced and unbalanced, selectable for Line, Mic, RTS1, RTS2 and ClearComm, or AES Digital (Dante selectable for RJ45 inputs)Audio Input Jack: 2 x combo XLR/TRS/AES3 connectorsAudio Input Impedance: Greater than 2K balanced; >1K unbalanced at any gain settingDante Connection: 2 x RJ45, 4 audio RX channels, internally routableEthernet Connection: RJ45USB Connection: USB-C on front panel for firmware updates via Wireless DesignerIRDA: IR transceiver for receiver setupHeadphone Jack: 3.5 mm stereo jackPower Requirements: 9-18 VDC via Hirose 4-pin connectorPower Consumption: <10 WattsWeight: 2.2 lbs (997.903 grams)Dimensions:- Height: 1.750 in. / 44.45 mm- Width: 8.375 in. / 212.7 mm- Depth: 7.750 in. / 196.8 mm
