Powering - AKG SPC4500 Manual Del Usuario

• Please note that these antennas may boost their RF output (ERP) in their pre-
ferred directions. In order to keep RF output within legal limits, make sure to
use antenna cables of the correct length for each type of cable, e.g., RG58:
16 ft. (5 m) for an RA 4000 W or 33 ft. (10 m) for an SRA 2 W.
• To power the SPC 4500 you can use either a suitable AC adapter or the optional PSU
4000 central power supply.
• Do not connect to the SPC DC input any AC adapter other than a type deliver-
ing an output voltage of 12 VDC and an output current of 1.4 A or higher.
• Check that the AC mains voltage stated on your power supply is identical to the
AC mains voltage available where you will use your system. Using the power
supply with a different AC voltage may cause irreparable damage to the unit.
• If you connected neither a suitable standard AC adapter nor a PSU 4000 to
DC ONLY 12 V/2 A SST, you will need to power each transmitter from a sepa-
rate power supply.
1. Connect the DC cable of a 1.4-A AC adapter or the DC output on the PSU 4000 to
the DC ONLY 12 V/1.4 A SPC jack on the antenna combiner rear panel.
2. Connect the DC cable of a 2-A AC adapter or the DC output on the PSU 4000 to the
DC ONLY 12 V/2 A SST jack on the antenna combiner rear panel.
3. Connect the AC adapter/PSU 4000 to a convenient AC outlet.
