Logger Patch
‘Amplified’
Description
The Total Recall Logger Patch ‘Amplified’ (TR-LP-A) enables recording from digital PBX & VoIP handsets
where there is no-side tone or the level of the microphone is too low to trigger the recorder. The TR-LP-A is
simply connected between the handset / headset cord (Curly Cord) and the PBX / VoIP telephone and then
wired back to the Total Recall Recorder.
Some phone handsets have different microphone and earpiece outputs to the RJ11 (4P4C) plug. Normally
the center two wires on the handset / handset jack are the earpiece circuit and the outer two wires are the
microphone. If your telephone does not use standard connections, there is a Handset Splitter included in the
pack to reverse the input connections to the TR-LP-A.
The TR-LP-A requires a 12vDC power pack to power the amplifier which will give up to 30db gain on the
microphone and 10db gain on the earpiece. This power pack is NOT supplied with the TR-LP-A.

Installation
Depending on the type of connection of your handset / headset connection there are two ways to connect
the TR-LP-A.
Normally the center two wires on the handset / headset jack are the earpiece circuit and the outer two wires
are the microphone.
There is two ways of determining which configuration your handset is.
1. Unplug the handset from the telephone and using a Multimeter set to ‘ohms’ and the ear piece next
to your ear, touch the meter probes first on the centre two connectors of the plug, if you hear a click
in the earpiece when you make contact the handset is standard. If not try to probe the outer two
contacts. If nothing is heard on either you may not be making contact with the probes.
2. Connect the TR-LP-A the standard way. If the recorder only records one side of a call try the NoN
standard connection.
