Page 7: Introduction
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: •... -
Page 8: Unpacking And Inspection
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. -
Page 9: About The Dmic-24
DMIC-24 About the DMIC-24 The SoundPals DMIC-24 is a dual microphone pre-amplifier with a built-in, 24-bit analog-to-digital AES converter. The unit takes two low-level, low-impedance inputs, amplifies the signals, and converts them to one AES output on both XLR and BNC outputs. - Page 10 AES REF RIGHT IN LEFT IN 1) DMIC-24 Version — the printed legend indicates the default frequency (either 44.1 KHz or 48 KHz). 2) Power Connector — accepts the power jack from the 6 VDC power supply. Refer to “External Power” for more information regarding external power.

Page 13: Advanced - Sub-Mix From Analog Equipment
In this application, SoundPals are combined to provide a sub-mix (from analog equipment). Dual mics feed the DMIC-24, and then the DMIX. An analog ATR is converted in the ADC, routed through a DFADE for level control, and then to the DMIX. -

1. On the rear panel, remove the four Phillips screws from the four corners of the SoundPals module. 2. On the front panel, remove all Philips XLR mounting screws from the SoundPals module. 3. On the front panel remove the BNC nut and associated lock washer. -
Page 19: External Power
Any power supply meeting these specifications will supply adequate power for a single SoundPals module. Although the specification is written for power supplies running from AC line inputs, DC (battery) sources may be used if they meet all of the listed requirements. -

(CE compliant). Note the following important points regarding the DMIC-24: • Under normal conditions, a DMIC-24 requires about 300 mA. • When phantom power is used, 500 mA (with low ripple) is required. Only the GPS-supplied universal power supply or the Elpac MI2007 is satisfactory for the DMIC- 24, when phantom power is used.
