Allo USBridge Signature - Ultra Low Noise Audio Streamer with Raspberry Pi Compute 3+

USBridge Sig was build using RPI compute module so from a software point of view, this will give you access to the latest kernels. The focus of the device is to lower the noise on USB bus with USB hub IC (TI) and a separated Ethernet to USB IC (Axis).

To lower the noise of the USB Allo had to lower noise on EACH rail. In total, USBridge Sig uses more than 30 LDOs. Even the SD card power rail has a dedicated LDO. There are zero switching elements on board. Of course, since this is based on RPI compute, Allo decided to include the standard RPI connector. Anything that works on an RPI will work on the USBridge Sig. For example, you can use a DigiOne / DigiOne Sig to make a full fledge streamer that outputs USB, BNC and coaxial.

Technical Details:

• Audio output on USB is full 512 DSD / PCM 768Khz (DSD 1024 theoretically possible)
• 10 layers PCB
• 30+ LDOs on board
• RPI connector compatible with any HAT PCB
• 3 USB ports, 1 reserved for DAC, 2 for WIFI/BT dongles
• Ethernet Speed tested at 330Mbs
• 3 x USB 2.0 Host: 1 on rear side marked as USB CLEAN, 2 on front side marked as Wi-Fi/BT (USB 2.0 ports capable of delivering up to 900mA)
• 1 x HDMI (Rear side)
• 1 x Gigabit Ethernet Port (AX88179 chipset) MicroSD card slot for OS (8GB or above)
• Power: 5V/3A through USB-C connector DigiOne Signature Clean Power: 5V/1A adaptor source or battery pack power 5V to 9V range LED Status: Power (PWR) green LED shows the power status and ACT red LED shows the SD card activity

Allo Usbridge Signature		Allo USBridge Signature Aluminium Case
USBridge Signature uses the Raspberry Pi compute module to leverage the latest kernels. The aim of the Allo Usbridge is to have the noise as low as possible. By means of a USB bus with USB hub IC (TI) and a separate Ethernet to USB IC (Axis).		Aluminium Case for USBridge Signature or USBridge Signature + DigiOne Signature.

Allo DigiOne Signature		Allo Shanti Dual Power Supply
The DigiOne Signature from Allo is the most advanced digital SPDIF transporter for the Raspberry Pi with BNC- and Coaxial-outputs. It delivers even lower interfering signals and noises thanks to its new power management with split PSUs for Pi and sound card. The additional case panel with the cutouts for the DigiOne Signature is required for the case.		The Allo Shanti is a linearly regulated power supply with two outputs (5.2V / 3A and 5.2V / 1.2A) for the individual powering of a Raspberry Pi and sound card. Ideal for Allo DigiOne Signature.
