Description
The AllScan UCI120 USB Communications Interface is a professional-grade yet low cost USB Audio/PTT communications interface that sets a new standard for AllStar, EchoLink and other PTT communications applications. The UCI120 provides the mic gain controls and Line Out jack standard features, and adding additional interior controls to fine-tune audio and mic AGC parameters.
The UCI120 is designed and optimized for use with communications microphones, speakers and other audio equipment, and is not intended to directly interface to radio transmitters or receivers.
Features
- Comprehensive LED status indicators for USB host status, Mic PTT (ASL COS), Mic Signal & Clip, and RX (ASL PTT). The mic signal and clip LEDs make it quick and easy to set mic input levels while minimizing any risk of ADC clipping
- Mic Gain Adjust and Mic Boost controls provide a 50dB gain adjustment range, supporting a wide range of communications microphones and dynamic mics. An internal 10Ω–1,500μF filter on the analog power supply ensures the lowest possible noise, particularly with older preamplified mics that do not have good supply voltage filtering or mics that combine audio and power on one line
- TRRS Line Out jack supports stereo TRS line out and an external mic in on the R2 pin with switchable bias voltage to power electret mics and headsets
- Insert I/O Jack supports the use of external audio processors. channel strips, mixers, and other audio systems. 3.5mm Tip=Send (from AGC out) Ring=Return (to ADC in)
- Internal trimmer potentiometers and DIP switches enable adjustment of nearly all mic preamp and AGC parameters. Over a dozen interior header and test point pads support easy access to all audio, power, GPIO and LED lines
- Extruded aluminum enclosure with ferrite and bypass cap filtering on all I/Os maximizes durability and EMI/RFI resistance. Optimized PCB layout with separate analog and digital power supplies and ground planes ensures extremely low noise and clear audio
- 6dB/octave bandpass filters ahead of the AGC mic preamp, ADC, and speaker amp reduce ADC clipping and AGC gain-pumping, and minimize thumps, clicks and other background noise. These filters have a smooth response curve supporting extended frequency response for other audio applications.
- Supports full-duplex audio with no dependence on PTT or COS. Works as a standard USB audio interface on Win, Mac & Linux in addition to fully supporting AllStarLink and HamVOIP
The UCI120 is now in full production. As we receive the completed PC boards from the factory we then assemble them into the enclosures and fully test each unit. Most orders ship within 3 days.
UCI120
Includes a fully assembled & tested unit, ready to plug into any RPi or MiniPC running ASL, HamVOIP, DVSwitch, or other PTT communications apps.
No Raspberry Pi, USB lead, mic or speaker is included.
Recommended Microphone:
It’s recommended to use a microphone such as the Genuine Alinco EMS-57 DTMF Hand Mic. This is the most popular DTMF hand mic on the market due to its clear audio, excellent build quality, and heavy-duty long coiled cord.
The DTMF functions on the Mic can be used to control the AllStarLink node directly without a PC or App.
Attach an external speaker with a 3.5mm mono plug.
Ensure you are using a USB-C data lead (some USB-C leads are only for charging and don’t have the data wires)
