1. Sensor Input Terminal [SENSOR INPUT 75 Ω]: Connection via F-connector and coaxial
cable for the infrared wireless sensors . It also supplies power to the sensors (24 V) .
2. Input Terminals [TV/DVD, CD, COMPUTER, MP3]: Connections for TV/DVD, CD,
COMPUTER, and MP3 .
3. Line Output Terminal: Provides a line level output for connection of personal FM systems,
recording devices, or video conferencing systems . All input signals, including microphones
and auxiliary inputs, are mixed and provided at the line output terminal .
4. AUX mute setting switch [OFF/LOW/HIGH]: Default setting is LOW . Sound from the
microphone will decrease (LOW or HIGH) the volume of external audio devices that are
connected to the input terminals . The OFF setting doesn’t allow for muting . The LOW setting
provides for a standard level of attenuation . The HIGH setting provides for faster attenuation .
Set the switch to LOW for normal operation .
5. Speaker Output Terminal: Connections for the speakers (8 Ω) .
6. PA Input Terminal: When a Public Announcement system is connected, announcements
are played through the speakers . The user can also select to reduce the auxiliary input levels

devices, connect the ground terminal of each device to reduce the difference in potentials
between devices .
10. Mount for Cable Clamp: Used to bundle cables and speaker wires with tie wraps .
11. DC Power Supply Terminal [24 V IN, 1.2 A]: Connects the specified AC adapter for power .
