DESCRIPTION

MODEL AOP-SP70 AUDIO CONVERSION UNIT

Model AOP-SP70 is usually paired with the TLO to convert the signals of Model
TLO for compatibility with the receiving device for providing two-way audio. The
AOP-SP70 drives the audio signals into the audio input and output of the IP
Camera, etc, for transmission over the network and to an existing computer (or
other devices) at the receiving site. Person at the receiving site hears the audio
through the computer speaker or through a headphone. For talkback to the
remote site (TLO location), the computer’s microphone is used to transmit audio
back through the network to the AOP-SP70. It is then amplified and sent out to
the speaker portion of the remote TLO. The AOP-SP70 provides power to the
TLO and contains adjustments for microphone gain and speaker volume. A 12Vdc
power supply is included with the AOP-SP70.

MODEL TLO OUTDOOR SPEAKER/MICROPHONE

Model TLO is a two-way speaker and microphone and re-entry horn for high
volume penetration. Weatherized for outdoor applications, the microphone and
speaker horn are all within one housing. In operation, the TLO together with the
AOP-SP70 provides hands-free bi-directional audio communication with the audio
receiving device (DVR, IP Camera, etc.).

MICROPHONE CONNECTION OF TLO

The short cable extending from the back of the TLO is the microphone connection and consists of three wires:
red, black and bare. Using recommended wiring (West Penn 356 or equivalent), make microphone
connections using 20 gauge wire nuts and matching red wire with red, black with black and bare wire with

bare wire. See diagram next page.

SPEAKER CONNECTION OF TLO

Speaker connection is located near the rear of the TLO and has a plexiglass window. Remove window and
connect the speaker portion of West Penn 356 (green and white wires) to the two terminal screws marked 1
and 2.

CONNECTION TO AOP-SP70

Locate the 4-pin terminal block (marked A, B, C, SP) and connect as follows:

1) Red wire goes to Pin B Audio Output

2) Black wire goes to Pin C Ground (audio)

3) Bare wire goes to Pin C Ground (speaker)

4) White wire goes to Pin SP Speaker Output

NOTE: Pin “A” is not used. Both black and bare wire connect to Pin C.

CONNECTION FROM AOP-SP70 TO DVR, IP NETWORK CAMERA, ETC.

After wiring connection has been applied to the 4-pin terminal block of the AOP-SP70, run other end of cable to the audio
receiving device’s audio Input/Output (usually either RCA, 3.5mm mono or 3.5mm stereo). If Audio In/Out of DVR, IP
Camera, etc. is 3.5mm type, refer to the specific instructions to determine if mono or stereo. Solder on the appropriate
plugs to match the “Audio In” and “Audio Out” of the DVR, etc. as shown on page 5.
