Page 4: Introduction
Introduction What are SoundPals? Each RJM & Associates SoundPals module is essentially a digital audio building block that can be used independently, or interconnected to perform more advanced mixing and audio processing functions. SoundPals can be used in both standalone and system configurations: In a “standalone”... -
Page 5: Unpacking And Inspection
SoundPals are delivered with a power connector only. A separate power supply must be obtained. RJM & Associates offers several power solutions for both domestic and international customers. Refer to “External Power” for detailed power specifications for users who wish to configure their own power source, rather than purchase one from RJM. -
Page 6: About The Da-14
DA-14 About the DA-14 The RJM & Associates SoundPals DA-14 is a one-input, four-output “data regenerator” for distributing AES digital audio signals. Two versions of the DA-14 are available: Model A • The DA-14/A provides four balanced AES3 outputs on XLR connectors. - Page 7 AES OUT 1 AES OUT 2 AES OUT 3 AES OUT 4 1) DA-14 Model — the printed legend indicates the model: A (AES, balanced) or B (AES3ID, unbalanced) NOTE The Model A (with balanced XLRs) is shown above. The Model B provides unbalanced BNC connectors.

Page 8: Installation
Plug a 6 VDC power supply into the appropriate voltage outlet for your specific country, and connect the end of the cord into the DA-14 rear panel jack marked +6V. Secure the locking ring finger tight. The green LED on the front panel lights when power is applied. -
Page 9: Operation And Application
S/PDIF to AES conversion • Because the DA-14 can operate in a range as low as 165mv, it can be used as an S/PDIF to AES converter. By using an S/PDIF adapter on your S/PDIF source and connecting it to the DA-14’s BNC input, you can achieve full level AES output (times four), provided that the source output is above the 165mv threshold. -
Page 10: Interconnection
Basic Digital Distribution • In this application, the DA-14’s input is connected to an AES source (such as the ADC- 24). The unit’s four AES digital outputs are connected to AES destination devices in your facility. Note that both DA-14 models are shown. -
Page 11: Multiple Outputs
Multiple Outputs • In this application, three DA-14 units are bridged together to produce 12 identical AES outputs. Note that the last DA-14 in the chain is terminated externally with a 75 terminator. NOTE All internal termination jumpers should be removed for this configuration. Refer to the “DA-14 Internal Jumpers”... -

AES signals, place jumper J903 between pins 2 and 3. When the jumper is between pins 1 and 2, the LED only indicates invalid AES signals (this is the default position). DA-14 Troubleshooting The table below lists several DA-14 problems, and provides a variety of “checklist” procedures designed to solve them. Problem Procedure No signal at any •... -

Page 15: Closing The Module
Closing the Module Use the following steps to close the DA-14 module: 1. Ensure that product label is on the bottom. 2. Carefully slide the internal circuit board and rear panel assembly through the housing. If BNC connectors are present, keep the case horizontal so that the bushings stay with the connectors. -
