D-A2

D-A2 – Line Output Assembly

The D-A2 is a passive audio output module that provides one or two unbalanced consumer-level audio outputs from a balanced line-level source. Designed for professional AV installations, it ensures reliable signal conversion and isolation in systems requiring consumer-level outputs.

The module features gold-plated RCA jacks for high-quality signal transmission and corrosion resistance. Transformer isolation between the balanced input and unbalanced outputs prevents ground loops and interference. The input shield is separated from the chassis ground to reduce hum induction.

The D-A2 fits standard wall boxes (e.g., RDL WB-1U) or can be mounted directly into cabinets or racks. It is not intended for use as an audio input panel.

Functionality

• Application: professional AV installations, audio distribution systems
• Signal conversion: from balanced +4 dBu line level to unbalanced consumer level
• Supports single or dual outputs from a mono source
• Transformer-isolated outputs – eliminates interference and ground loops
• Isolated input shield – reduces hum
• Mounting: wall boxes, cabinets, or racks

Features

• Connector type: 2 × RCA (phono), gold-plated
• Signal type: unbalanced audio
