About the DAC-24
The RJM & Associates SoundPals DAC-24 is a stereo, 24-bit, AES digital-to-analog converter.
The unit offers the following features:
•
Stereo headphone monitoring with level control
•
24-bit D/A converter
•
Automatic detection and de-emphasis
•
LED indicators for emphasis and valid AES input
•
Separate analog output level adjustments
(-10 to +4 dBu at -20 dBFS)
•
Terminating or bridging input
•
Optional rack mounting tray (1 RU)
•
Compact size, rugged construction
The DAC-24 takes one AES input (on an XLR or BNC connector) and converts it to two analog
outputs (on XLR connectors).

GAIN
1) Stereo Headphone Connector — accepts standard low-impedance TRS stereo
headphones.
2) Headphone Gain Control — adjusts stereo headphone volume. The control does not
affect analog output levels.
3) Left Analog Output Gain Trim — the L GAIN trim sets the analog line level for the left
channel output.
4) Right Analog Output Gain Trim — the R GAIN trim sets the analog line level for the
right channel output.
5) Emphasis Detection LED — the EMPH LED lights when the channel status bits of the
AES input signal indicates that pre-emphasis has been applied to the signal. If the
sampling frequency is within 4% of 48 KHz, 44.1 KHz or 32 KHz, de-emphasis correction
is automatically applied.
6) AES Input Error LED — the ERR LED lights when no signal is applied to the AES 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.
