transmitters that have traditionally required specialized adapters that attach to external
batteries. PSC has effectively eliminated the need for this additional hardware with
these auxiliary power supplies. The NP-1 battery receptacle is located in the bottom
right corner. This receptacle will also accept 10 AA alkaline batteries housed in a
battery tray designed to be inserted into the NP-1 battery slot. PSC doe not
recommend that alkaline batteries be used when powering wireless receivers; however,
as they will not deliver enough power to simultaneously operate the mixer and the
receivers. External power supplies can be introduced through the Hirose™ 4-pin plug
located in the lower right corner. The pin configuration of this connector is Pin 4 (+,
positive) and Pin 1 (-, negative) and accepts DC power from 10 – 18 Vdc. This DC
input is protected from reverse polarity to that the mixer will not be damaged from
inadvertent polarity mismatch. In the event of reverse polarity the mixer will simply not
power up.
Conclusion
PSC has set numerous benchmarks with the AlphaMix ensuring that it will be a
dominant force among ENG/EFP mixers in its class. The ergonomic design allows ease
of operation and accessibility to all critical switches from the outside of the mixer. A
small number of switches are located on the bottom of the mixer; however, the need to
adjust these controls is rare. In the event that they do need adjustment they can be
easily accessed by slipping the mixer out of its carrying case. Numerous PSC
exclusives have been unveiled with this versatile mixer that set it apart from other
mixers in its class including:
1. Very low noise preamplifiers.
2. 3 LED meters on each input channel.
3. Remote control slide fader that boom mounts.
4. Dual Hirose™ 10 pin connectors for multi-camera feed.
5. Balance mono output.
6. Internal NP-1 receptacle
7. Built-in and calibration switchable battery monitor.
8. Custom LCD peak meters that emulate Camcorders.
9. Wear-proof subsurface silk-screening.
