Production Update 5/16/22 - The assembly house shipped the first production units to us. DHL says we will get them Tuesday next week (17th). We will need a few days to begin testing and shipping units. Current back orders should be completely shipped by week of the 30th.
Pi 2 Design - Mercury Streamer
The Mercury Streamer, designed and manufactured by PI 2 Design, is a Compute Module 4 based device designed for Professional, Studio Grade, Digital Audio Streaming. The Mercury Streamer converts the Compute Module 4 I2S Interface to High Definition Professional Digital Audio Coax, OPTO and Balanced XLR. These multiple, simultaneously active digital audio outputs allow the Mercury Streamer to optimally interface with virtually any High Performance DAC on the market.
The major features of the Mercury Streamer are as follows:
The major features of the Mercury Streamer are as follows:
- COMPUTE MODULE 4 - This module provides 4 High Performance ARM Cores, Dual 4K HDMI Output, PCIe x1, Gigabit Ethernet, 8GB DRAM
- M.2 2280 SSD - A Standard M.2 Socket is provided for nVME Storage via the CM4 PCI Express x1 Link. The socket supports both “M” and “B” Key devices.
- GIGABIT ETHERNET - A standard RJ45 Provides the interface to the CM4 Gigabit Ethernet I/F.
- DUAL EXTERNAL USB2.0 - This connector provides two USB2.0 Host Ports.
- EXTERNAL HDMI - One 4K HDMI Connector allows access to CM4 HDMI Output 0.
- AES TRANSMITTER – The industry standard WM8804 converts the CM4 I2S stream to AES3/SPDIF formatted data at 24-Bit up to 192Khz Frame Rate
- AES COAX OUTPUT – A 1:1 Isolation Transformer provides Bit Perfect Impedance Controlled Digital Audio Data @ 1V AES Standard Level.
- AES BALANCED OUTPUT – An RS-485 Transmitter with a 1:1 Isolation Transformer provides balanced audio data via the Professional XLR Connector
- TOSLINK OPTICAL OUTPUT – Isolated Optical Transmitter Drives Consumer Level DAC’s
- SPDIF COAX OUPUT - A 1:1 Isolation Transformer provides Bit Perfect Impedance Controlled Digital Audio Data @ 0.6V Consumer Standard Level.
- DIFFERENTIAL I2S OUTPUT – An LVDS Differential Transmitter drives the I2S Bus over an HDMI Connector. Pinout conforms to PS Audio Standard.
- HIGH RESOLUTION CLOCKS – A pair of Ultra-Low Noise NDK NZ2520SDA oscillators drive the WM8804 in non-PLL mode for the lowest possible noise.
- ULTRA-LOW NOISE LDO’s – Two Ultra-Low Noise LT3042 LDO’s (0.9 uV noise and 80 dB PSRR) are used to supply the WM8804 and the NDK Clock’s.
- LINEAR PRE_REGULATOR - LT2941 LDO 5V pre-regulator allows the entire power chain to be linear when an external linear PSU is used.
- LOW NOISE PCB LAYOUT – 4-layer Split Ground PCB with noise reduction techniques refined from years of High-Speed Mixed-Signal Design work.
- EXTRUDED ALUMINUM ENCLOSURE – Rugged, Aircraft Grade Aluminum, Anodized for Scratch Resistance
- PRE-PROGRAMMED 32GB SD CARD - Mercury comes with a 32GB SD Card loaded with Volumio 3.x (other OS's TBD)
