Telecast Adder 162 User Manual page 9

Any 15 VDC external power supply used with the Adder 162 must provide 2.5 amperes
continuous current.
Any 15 VDC external power supply used with the Adder 322 must provide 3.5 amperes
continuous current.
Although the Adder 162/322 assembly will operate at 10 VDC, ≥13.8 VDC is required to charge
the internal backup battery. System operation below 15 VDC can cause battery charge
depletion.
The internal battery is automatically charged whenever 13.8 VDC is provided at the INPUT
POWER connector shown in Figure 2 on page 3. Full charge takes 16 hours, and will power
Model 162 for 30 minutes and Model 322 for 15 minutes.
Audio I/O is via 3-pin XLR connectors with industry standard wire locations. See Table 2 and
Figure 4.
The XLR connectors are located on the front panel of each module. On the input modules, XLR
connectors are female Neutrik type NC3FPR-H. On the output modules, XLR connectors are
male Neutrik type NC3MG-H. Refer to Figure 4.
