Phone Patch Level Settings
The input and output levels should be adjusted per the phone patch’s instructions. The summary below
gives a brief overview of the high level characteristics and phone patch settings for configuration with
the SLR 5000 Series Repeater.
Disc
The Receiver audio yields 330 mV rms into 50 kΩ with an RF input signal deviating at 60% RSD.
With the phone patch's own loading impedance, the "Disc" signal delivered to the phone patch is at a
high enough drive level to leave jumper JP1 in the factory default position (position A).
Tx Audio
The transmitter yields 60% RSD with 80 mV rms into the Tx Audio port.
The "Tx Aud" signal delivered by the phone patch is at a high enough drive level to leave jumper JP3 in
the factory default position (position B).
CTCSS/ DCS DECODE INPUT/ COR
Set the jumpers on the phone patch as follows:
• Set jumper JP6 to position A, to match the SLR 5000 Series Repeater's active low indication of a
PL/DPL detect.
