Line Output Assembly The D SERIES-A2 is a passive audio output assembly that provides one or two unbalanced consumer level audio outputs from a balanced line-level audio source. It may be connected to the +4 dBu line level output of any RDL product, even if that output is simultaneously feeding other equipment. The D SERIES-A2 circuit design provides a high degree of audio isolation if a user accidentally feeds a consumer-level source into the D SERIES-A2. The attenuation of such reverse signals is sufficient for most installations. Active RDL modules are available for complete isolation if required. The D SERIES-A2 output jacks are transformer isolated from the balanced line input, and the input shield is separated from the case ground to reduce the possibility of induced hum. The D SERIES-A2 is not intended as an audio input panel.The D SERIES-A2 fits directly into back boxes, available from RDL, to fit cabinets or US or international walls ( RDL WB-1U). It may also be mounted directly into cabinets or most standard US single gang electrical boxes.Features: Wall Mounted Consumer Level Outputs Single or Dual Outputs from Mono Source Gold Plated Phono Jack Outputs Transformer Isolation of the Line Outputs Unbalanced Audio Outputs from a Balanced Line Input High Attenuation of Reverse Signals Specifications: Input Level: +4 dBu, nominalInput Connector: Full size barrier blockInput Impedance: 10 k balanced bridging, monaural Output Connectors ( 2): Phono jacks with gold contactsInput Connections ( 4): CASE GROUND, SHIELD, + , - Frequency Response: 50 Hz to 20 kHz ( 1 dB) Attenuated Signal-Reverse Path: < -50 dB ( at 150 balanced source output, +4 dBu reference, -10 dBV signal injected into output jack)Power Requirement: PassiveDimensions: Height: 4.13 in. 10.49 cm-Width: 1.7 in. 4.32 cm-Depth: 2.15 in. 5.47 cm Mounting Box Req.: Width: 1.80 in. 4.57 cm-Depth: 1.75 in. 4.45 cm
