Connecting to Remote Devices
Physically install the remote SelecTone device(s) following the instructions included with the device.
Balanced Line Application
For 300GC, 300GCX, 300X, 302GC, 302GCX, 302X or 50GC speakers, an AM25CK Connector Kit is
required for connection to the balanced signal output of the 300SCW-1. The AM25CK properly terminates
the balanced signal lines to the amplifier in the 300GC, 300GCX, 300X, 302GC, 302GCX, 302X and
50GC. As shown in Figure 3, connect the white input wires on the AM25CK to the terminals TB1-4 and
TB1-5 of terminal block TB1 on the 300SCW-1. The AM25CK and AM70CK Connector Kits are NOT
polarity sensitive, but polarity must be observed when placing speakers in close proximity to each other.
