Unbalanced Line Application; Figure 4 25 Vrms Connections; Figure 5 Model 300Ck Connections (Unbalanced Line) - Federal Signal SelecTone 300SCW-1 Manual De Instalación Y Mantenimiento

See Figure 4. For 25 Vrms line operated speakers, connect them directly to the balanced signal output of
the 300SCW-1. Connect the speakers in parallel to the terminals TB1-4 and TB1-5 of terminal block TB1
on the 300SCW-1. Unlike the unbalanced line output, this output is not switched.
IMPORTANT: Use the balanced signal output only if there are no SelecTone system devices connected
to the unbalanced signal output (across TB1-1 and TB1-2).

Unbalanced Line Application

For existing SelecTone systems using the 300CK Connector Kit, use the unbalanced signal outputs
on the 300SCW-1. A 300CK Connect Kit is required to connect a 300GC, 300GCX, 300X, 302GC,
302GCX, 302X or 50GC to the unbalanced signal lines. The 300CK properly terminates the signal
lines to the amplifier in the 300GC, 300GCX, 300X, 302GC, 302GCX, 302X and 50GC. Connect the
blue wire on the 300CK to the
SIG HI
300CK to the wire from the 300SCW-1 as shown in Figure 5.
