POWER SUPLY UNIT

Wersja-C

Power for the NV73pq preamplifier is provided by a dedicated external power supply unit PSU NV73.
The PSU has two output sockets and can power two preamps NV73pq or NV73p.
The PSU's design allows disconnecting signal ground from the ground to eliminate the ground loop
during studio setup.
PSU's chasis is made of the same materials as the NV73pq preamp and harmonizes with its design.
PSU NV73 is sold separately.
