Description

The Digi-2 (dual input AES/EBU to analog converter module PCB) allows selected Wohler Technologies products to receive input

signals in the AES/EBU or SPDIF digital audio data formats. Sampling rate and format selection are sensed and set automatically.

Two front panel mounted bi-color (red/green) LEDs provide visual indication of input signal status. The LEDs light green when

receiving a valid, error-free data stream but turn red when errors are detected. There are two AES/EBU inputs, which can be

configured with unbalanced 75 Ω BNC connectors or balanced 110 Ω XLR connectors. This PCB also features a four-channel

balanced analog line-level output, which can be configured with unbalanced 75 Ω BNC connectors or balanced 110 Ω Phoenix or

XLR connectors.
