INSTALLATION INSTRUCTIONS
SSL-A & SSL-B SoundSource Links
OWNER’S MANUAL
The SSL-A & SSL-B SoundSource Links are modules that permit
high quality audio to be transmitted over long lengths of
twisted pair cable. Specifically, they allow two remote audio
sources to be connected to the Aux1 & 2 inputs of the
SpeakerCraft SoundSource in-wall music center over Cat.5
cable. The SSL-A accepts normal unbalanced line level stereo
audio inputs and converts the audio to balanced outputs. The
balanced outputs are then passed over long cable lengths (up
to 500’ of Cat. 5) to the balanced line inputs of the SSL-B. The
SSL-B then converts the audio back to unbalanced line level for
connection to the Aux1 & 2 inputs of the SoundSource. Up to
4 SoundSources can be so connected to share the same two
audio sources. Connections are also provided for IR control of
the remote audio components.

SSL-A & SSL-B SoundSource Links
FEATURE DESCRIPTIONS
1.+/- 15V DC IN – 3.5mm 3-circuit jack accepts bipolar power input from the
SoundSource to power the SSL-B Link.
2.Aux1 & Aux2 Audio Out – RCA type jacks connect the unbalanced line
level stereo audio to the Aux1 & Aux2 Audio Inputs on the SoundSource.
3.IR In – 3.5mm 2-circuit jack accepts the IR REMOTE OUT from the
SoundSource for control of the remote audio sources.
4.Mounting Holes
5.GND IR Out – 2-terminal spring type connector provides for connection of
inter-room 2-conductor wire for IR control of the remote audio sources.
6.Audio Link In, Aux1 & Aux2 – Spring-loaded EZ-Connect terminals accept
wire sizes 18 to 28 AWG. Usually you would pull Cat. 5 twisted pair cable
for these balanced line audio input signals from the SSL-A.
7.12V DC IN – 2.1mm jack, center pin +. Accepts 12V DC regulated power
supplies to power the SSL-A Link. Use the SpeakerCraft
PS-1.0 Power Supply (included).
8.Aux1 & Aux2 Audio In – RCA type jacks allow connection of two standard
line level stereo audio sources (unbalanced) to the SSL-A.
9.IR Out – 3.5mm 2-circuit jack accepts the connection of IR Emitters for
control of the remote sources.
10.GND IR In – 2-terminal spring type connector provides for connection of
inter-room 2-conductor wire for IR control of the remote audio sources.
11.Audio Link Outputs, 1 through 4 – Spring-loaded EZ-Connect terminals
accept wire sizes 18 to 28 AWG. Usually you would pull Cat. 5 twisted pair
cable for these balanced line audio output signals for up to four SSL-B’s.
Shielded Cable Note: The SSL-A and SSL-B balanced line system, using
twisted pair unshielded Cat. 5 cable, has been found to work with excellent
signal to noise ratio under many simulated conditions. However, if you feel
there may be extremely high levels of EMI interference at the installation
site, it may be safer to pull shielded (Cat. 5) cable.
