Gain Setting - Gato Audio DPA-4004 User Manual

Gain setting

The DPA-4004 has a default voltage gain setting of 26dB. In some system setups it can be useful to change the voltage gain to adapt diff erent
connected equipment. The gain setting switches are located inside the DPA-4004 and can be adjusted with the assistance of a technician.
For each channel there is a two-way micro switch with these combinations:
Gain adjustment SW1
- 2.0 dB on
0.0 dB (default)* on
+2.5 dB off
+6.0 dB off
* The default state matches the voltage gain for the Gato Audio DIA-250 and DIA-400 integrated amplifi ers.
Please note that when a section is bridged, both micro switches for each channel must be set to the same value.
