Speaker Settings and Adjustments
Refer to Figure 10 for locations. It is recommended to use a No. 10440-002 Maintenance Cable (sold
separately) to perform the following adjustments.
Speaker Volume
The Speaker Volume potentiometer, R91, adjusts the signal level to the speaker from the page line. It is
accessible through a small hole in the bottom of the amplifier so there is no need to open the amplifier to
make this adjustment. The default setting is 4 watts for an 8-ohm speaker and 2 watts for a 16-ohm
speaker.
Warning: Maximum output power may exceed rated speaker wattage resulting in speaker damage.
Speaker Mute
The amplifier can mute the associated speaker during page operation to eliminate feedback. To mute the
associated speaker, remove the amplifier from the enclosure, if installed. Open the amplifier as
previously described. P11 on the Main PCBA mutes the speaker during page activation when in the
EN
position (default). P11 in the
DIS
position allows broadcast to the speaker during paging.
