Figure 94: CPS Configuration for L3276 Tone Remote Adapter
(For a 15 Channel Remote Control)
NOTICE: The above configuration is considered typical. The L3276 Remote Tone Adapter
provides alternate configurations that are supported by SLR 5000 Series Repeater as well. See
L3276 Remote Tone Adapter Manual for additional details.
Tone Remote Adapter settings
The input and output levels should be adjusted per the Tone Remote Adapter’s instructions. The
summary below gives a brief overview of the high level characteristics and typical Tone Remote
Adapter settings for configuration with the SLR 5000 Series Repeater.
Radio Rx
The SLR 5000 Series Repeater’s Receiver audio will yield 330mV rms into 50 kΩ with an RF input
signal deviating at 60% RSD. With the Remote Tone Adapter’s own loading impedance, the “Radio Rx”
signal delivered to the phone patch is at a high enough drive level to leave jumper S10 in the factory
default position (position is “out”).
