                TSA-2A1
Telephone Supervisory Adapter
For telephones that do not have side-tone on the ear piece











The TSA-2A1 is used to provide a method of connecting supervisor monitoring equipment to
the handset (or headset) circuit of a telephone that does not have side-tone (no mouthpiece
audio is present on the ear piece of the phone – also called talk-back). It can be used on
most telephone styles that have a standard modular handset or headset jack (4P4C). If the
phone you wish to monitor has side-tone, as with 99.9% of business phones, you should
use the simpler and less expensive
TSA-3LM.

Installation
The TSA-2A1 is supplied with cables and connectors which have been wired for use with
Total Recall and Telecorder. The cable between the TSA-2A1 and your recorder may be
extended as needed. Only the center two wires in the output cable (red & green) are used to
feed audio to your recorder.

1.  Unplug the handset cord from your telephone set and plug it into one of the two jacks on
the TSA-2A1 adapter labeled “Handset/Headset — IN/OUT”.

2.   Using the short cable which was supplied with the TSA-2A1, plug one end of the cable
into the handset jack on your phone and the other end of the cable into the remaining
“Handset/Headset — IN/OUT” jack on the TSA-2A1. Your telephone should now function
normally as you have simply connected a short extension into the handset cord. Normally the
center two wires on the handset jack are the earpiece circuit and the outer two wires are the
microphone. If your telephone does not use standard connections, the TSA-2A1 may have to
be re-wired so that the recorder is connected to the correct wires.

3.   Plug the supplied AC adapter into the “Power (12vDC)” jack and AC power.

4.   The “Audio Out” can now be connected to your supervisory equipment (voice logging
recorder, monitor amplifier, etc.). The TSA-2A1 comes with a twenty-five foot cable which can
be used between it and the input on your recorder. Do not connect the “Audio Out” to anything
other than the audio input of your monitoring equipment. Never connect it to a phone line.

5.   There are two small screwdriver adjustable controls on the TSA-2A1. One adjusts the
level of microphone audio that is on its output (up to 30db gain), and the other adjusts the
earpiece audio (up to 10db gain). Adjust clockwise to decrease, counter-clockwise to
increase the output level as needed. Secure the cables.

Notes:  The TSA-2A1 is warranted to be free from defects in materials or workmanship for
one year from the date of purchase. Damage to products resulting from physical abuse or
electrical misuse voids this warranty. Out of warranty units will be repaired for a nominal
handling charge plus the cost of parts and transportation. If the unit requires service,
disconnect and return to the factory or place of purchase for repair.
