Introduction
DA-14 User Guide Page 1
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:
•In a “standalone” configuration, each SoundPals module is designed to perform a specific
audio processing function such as ADAT-to-Analog conversion. In this way, each module
functions as a perfect low-cost adjunct to larger mixing consoles (such as the Graham-
Patten D/ESAM series) — for single-purpose processing tasks.
•In a “system” configuration, SoundPals can be linked to form more comprehensive digital
audio tools. For field recording, studio applications, and workstation applications,
SoundPals can be used to seamlessly perform functions that would otherwise require
extensive peripheral gear. Best of all, SoundPals “systems” can be re-configured quickly
and easily — to suit your changing audio production requirements.
All SoundPals modules are extremely compact, rugged, and identical in size for ease of
installation, interconnection, and use. In addition, SoundPals support AES3id. This allows
longer, more robust AES signal distribution using standard coaxial cable. Error free distances of
1000 feet can be attained using inexpensive coaxial cables.
Documentation Conventions
The following documentation conventions are used in this guide:
•Buttons, knobs, connectors, and switches are indicated in bold-faced capital letters. For
example:
Adjust the left GAIN TRIM to …
•Primary sections are listed in bold text, with a line above:

Signals and Values
Note the following important information regarding audio signal level:
•AES3 = Balanced output with 2 channels of digital audio (left and right)
•AES3id = Unbalanced output with 2 channels of digital audio (left and right)
Warnings
Please observe the following important warnings:
•Heed all warnings on the unit and in the instructions.
•Do not use this product in or near water.
•Route power cords and other cables so that they are not likely to be damaged.
Disconnect power before cleaning. Do not use liquid or aerosol cleaners; use only a
damp cloth.

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.
Power Supply Note
SoundPals are delivered with a power connector only. A separate power supply must be
obtained. Graham-Patten 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 Graham-Patten.

About the DA-14
The 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 Model A provides four balanced AES3 outputs on XLR connectors.
•Model B
The DA-14 Model B provides four unbalanced AES3id outputs on BNC connectors.
NOTE The printed legend on the rear panel indicates the DA-14 model.
Both models include one AES3 input (on an XLR connector) and one AES3ID input (on a BNC
connector). Note that only one input can be used at a time.
The DA-14 offers the following features:
•Choice of balanced AES outputs (XLR) or unbalanced AES3id outputs (BNC).
•Terminating or bridging inputs
•Accepts (and regenerates) any AES or AES3id digital input signal between 30 KHz and
50 KHz sampling frequency.
•Power and Status LEDs
•Optional rack mounting tray (1 RU)
•Compact size, rugged construction
The figure below illustrates the DA-14’s front panel:

1) AES Balanced Input — the AES IN XLR connector accepts a balanced AES input
signal.
2) AES Unbalanced Input — the AES IN BNC connector accepts an unbalanced AES
input signal.
NOTE Do not connect both AES inputs at the same time.
3) I/P ERR — this LED lights when no signal is applied to the input, or when the signal is not
valid. A non-valid signal exhibits errors such as format violations, bit errors, low level, or
incorrect frequency. When I/P ERR is lit, output is muted.
4) Power LED — the green LED lights when power is applied.
