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.
The DMIC-24 offers the following features:
•
Sensitivity adjustments in 5 dB steps (-20 to -60 dBu)
•
LED level indicators for normal and overload conditions
•
Support for phantom power with Enable/Disable switch
•
Significant status bits selectable with internal dip switch
•
Two low-level, low-impedance inputs on XLR connectors
•
One AES balanced output (XLR), plus one simultaneous unbalanced output (DATS on
BNC)
•
Recessed DIP switches, well-suited to field work
•
Optional rack mounting tray (1 RU)
•
Compact size, rugged construction
Two versions of the DMIC-24 are available:
•
44.1 KHz Model
This model defaults to 44.1 KHz, via the internal crystal. However, if an external
reference is applied to the
AES REF connector, the output frequency will lock to the
reference.
•
48 KHz Model
This model defaults to 48 KHz, via the internal crystal. However, if an external reference
is applied to the
AES REF connector, the output frequency will lock to the reference.
NOTE The printed legend on the rear panel indicates the default frequency.

1) Left Mic Sensitivity — the 8-position DIP switch adjusts left microphone sensitivity in 5
dB steps (-20 to -60 dBu).
2) Right Mic Sensitivity — the 8-position DIP switch adjusts right microphone sensitivity in
5 dB steps (-20 to -60 dBu).
3) AES Unbalanced Output — provides AES unbalanced output via BNC. Output is
concurrent with the rear panel balanced output (XLR) — both can be used
simultaneously.
