Connection Instructions
1. Turn the power switch off. Plug the included power supply into a surge-
protected 110VAC outlet and the 12VDC jack on the SoundBrick 550N. Only
use the power supply provided with the unit (12VDC, 500mA, center pin
positive). Many power supplies look alike, but provide different output. Using
the wrong one will void your warranty and may damage the unit.
2. Connect either the 8
Ω
or 1K
Ω
audio output jack to the phone system’s MOH
port using a mono RCA-to-RCA cable (included). If the sound system does not
have an RCA-style input, an adapter may be required (not included).
3. If you are using the night answer feature, select the incoming phone line to be
answered by the unit and split the line. For proper night answer operation you
must use the first phone line normally answered by the company’s phone
system. Connect one side of the split to the phone line’s original destination.
Connect the other side of the split to the phone line jack on the SoundBrick
using an RJ-11 telco cable (included).
IMPORTANT NOTE: The SoundBrick 550N must only be connected to a
standard analog loop-start telephone line, ahead of any other equipment
using that line. Installation on any other type of line, or on a KSU or PBX
extension will fail and may damage the other equipment and/or the
SoundBrick. To test the installation line, connect a normal analog home
telephone to the line. If the line type is correct, you will be able to place
an outgoing call and receive an incoming call using the home telephone.
4. Connect the optional 1/8” mini-plug trigger cable to the optional timer or other
trigger hardware if you are using this feature.
Step 3 – Load Messages
Messages load into the SoundBrick 550N from a cassette tape supplied by your
messaging provider and can also be loaded remotely by dialing into the unit using
a standard touch-tone phone.
Tape Load
Turn the power switch on and press the tape eject button. The motorized tape
drawer on the right side of the unit opens like a CD-ROM drive on a computer.
Place the tape into the drawer by gently sliding it under the retaining clip, audio
side facing front, then press the eject button, or momentarily push the drawer to
