If you need to send AES/EBU digital audio signals to multiple destinations, you must use a Distribution Amplifier (D.A.). Unlike analog audio, digital audio signal cannot be passively split using "Y-cords" or resistive dividers.

The new Digital D.A. 2X8 is the perfect solution! It provides up to 8 outputs from a single digital source. Its 8 outputs can also be split into two groups, providing 4 outputs each from a pair of digital sources.

 

Description

The Digital D.A. 2X8 is a dual-mode distribution system for AES/EBU digital audio signals. It is ideally suited wherever digital audio signals must be routed to multiple destinations. The Digital D.A. 2X8 produces outputs that are exact copies of the input signal(s). There are no changes to any data or timing, and no jitter, delay, or latency is added. The unit is compatible with any sample rate up to 96 kHz.

The Digital D.A. 2X8 has two inputs and eight outputs. There are two operating modes, selected by a recessed front panel pushbutton. In Single mode, unit operates as a 1-in, 8-out D.A: a single input signal is reproduced on all 8 outputs. In Dual mode, it operates as two independent 1-in, 4-out D.A.s: each of the 2 input signals produces 4 outputs. There is no interaction between the two channels.

The presence of output signals is confirmed via a front panel LED for each output group. All inputs and outputs are individually transformer isolated. Input termination is user selectable. Input signals are conditioned to correct for low levels and high frequency rolloff caused by long cable runs. The output signals conform to AES/EBU standards.

The Digital D.A. 2X8 uses euroblock connectors for all I/O. Mating connectors are supplied. The unit is powered with an internal AC power supply. The Digital D.A. 2X8 is 1/3 rack-width and can be rack mounted using the optional rack shelf, or wall mounted with optional wall/cabinet mounting brackets.
