Introduction What are SoundPals? Each Graham-Patten 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: •...
Unpacking and Inspection When you receive your SoundPals modules, inspect the cartons for signs of damage. Contact your dealer and the shipper immediately if you suspect any damage has occurred during shipping. Check the contents of each box to be sure that all parts are included. If any items are missing, contact your dealer immediately.
ADC-24 About the ADC-24 The SoundPals ADC-24 is a stereo 24-bit, analog-to-digital AES converter. The unit takes two line-level analog inputs (on XLR connectors), and converts them to one digital AES output (provided on both XLR and BNC connectors simultaneously).

6) Power Connector — accepts the power jack from the 6 VDC power supply. Refer to “External Power” for more information regarding external power. 7) Power LED — the large green LED below the power jack lights when power is applied.

Plug a 6 VDC power supply into the appropriate voltage outlet for your specific country, and connect the end of the cord into the ADC-24 jack marked +6V. Secure the locking ring finger tight. The green LED below the jack lights when power is applied.
To align the left and right analog outputs: 1. Connect a reference analog tone generator to the ADC-24’s LEFT IN and RIGHT IN connectors. 2. Turn on the reference tone generator, and adjust it to the level that you want to correspond to -20 dB below digital clipping.

• Advanced — Multiple Analog Inputs to Digital Mixer In this application, ADC and DMIC SoundPals are combined to provide multiple analog inputs to a digital mixer. An analog ATR feeds an ADC, and then to the mixer via AES.
ADC-24 Internal Jumpers This section provides information about the ADC-24’s internal jumpers and adjustments. NOTE For detailed instructions on opening and closing the ADC-24, see Appendix A, “Inside the Module.” The figure below shows the ADC-24’s internal jumper locations: Input...

2. Carefully slide the internal circuit board and front panel assembly through the housing. Keep the case horizontal so that the BNC bushing stays with the connectors. 3. Replace, but do not tighten, the four Phillips screws in the front corners of the SoundPals module.
Repeat with the four rear plate corner screws. 7. Replace all Philips XLR mounting screws at the rear of the SoundPals module. 8. Replace the BNC nut and associated lock washer at the rear of the SoundPals module. CAUTION Do not over tighten the screws.
