Connections - Bose FreeSpace 6 Installer's Manual

2.0 Installation

2.9.3 Connections

Note: To prevent excessive mechanical stress on the wire connections, use cable ties or other strain relief for the
signal and loudspeaker cables.
If using a push-to-talk microphone, be sure the push-to-talk switch is properly wired so that it places a short circuit
across the microphone output except when the user presses the switch.
CAUTION
Improper connection can damage both the source equipment and the FreeSpace
guide for information on nominal output voltage, output impedance, and balanced and unbalanced outputs.
Note: Sources are either balanced or unbalanced. Call 1-800-288-2673 (in the U.S. and Canada) or your local Bose
office and request the "Balanced and Unbalanced Source Terminals" information packet (PN183072).
Input connections
Paging microphone
Telephone systems (PBX) and a
central paging signal (such as in
malls)
Music source
Remote control
The remote volume control wires carry small DC voltages (less than 15V) derived from high impedance circuits and
do not constitute a safety hazard. Two of the conductors are at the chassis ground potential of the amplifier.
• Use the black pair to connect the potentiometer to the Remote Volume connector on the amplifier
• Use the white pair to connect the switch to the Remote Select switch on the amplifier
The bare wires connecting the remote control to the amplifier are not a hazard. Shorting any or all of them will not
damage the system. However, if the wires are not properly terminated, there may be unwanted source selection or
muting of the system.
Note: For convenience during setup, connect the remote control temporarily using a short cable.

Instructions
1. Connect the signal wires of the paging microphone to the quick connect
terminal block.
2. Insert the quick connect terminal block into the paging microphone input.
Follow the connection diagram for a balanced or an unbalanced source found
in the "Balanced and Unbalanced Source Terminals" information packet
available from Bose. Call your local Bose office and request it.
The following two audio sources are available:
• Music Input A accommodates either balanced or unbalanced configurations.
– For balanced sources, use the quick connect terminal block.
– For unbalanced sources, use the RCA (phono) connectors.
• Music Input B accepts unbalanced RCA plugs only.
The cable should consist of two wire pairs (22-24 gauge or heavier), with an
overall jacket. Select the wire according to safety agency requirements for the
installation. No hazardous voltage is present on these wires. One twisted pair
might be two white wires, the other pair two black wires.
