Typical 909A/B universal coupler
The 909A is the direct current (DC) version of the coupler, and cabinet power
supplies -48 VDC power. The 909B is the alternating current (AC) version, and
power is supplied from a separate power supply (such as the KS-22911L2).
The DIP switches on the unit set:
■
Protection/Paging selection
—
For AUX trunk paging and malicious call
trace, set to C2. Set the switch to C1 for all other applications.
■
Output attenuation (-9 or -15 dBm)
—
Setting depends on output level of
music source.
■
Output impedance (8 ohms, 1.5 k
Ω
, and 50 k
Ω
)
—
This switch only
requires setting if the Protection/Paging switch is set to C2 and the coupler
is supplying background music to a customer-supplied paging amplifier.
The pinouts for J1, J2, and J3 are provided in
Table 2
,
Table 3
, and
Table 4
. Refer
to these tables when connecting music or paging equipment.
