7. Manual On/Auto On Switch
Put this switch in the Auto On position if the amplifier is
being used as part of a JBL Synthesis system. When used
in this way, the S5160 will automatically turn on when the
Power switch is depressed and the surround processor is
activated. For other installations, or should individual control
of each component be desired, put this switch in the
Manual On position. The amplifier will then be controlled
solely by the front-panel switch.
8. In/Out DIN Jacks
If you are using the amplifier as part of a JBL Synthesis
system, it is necessary to use these jacks to interconnect to
other system components so that control signals (Power
On/Off and Music/Cinema mode switching) can be trans-
mitted from one unit to the next, starting at the surround
processor, through the equalizer and amplifiers, and ending
at the speakers. Follow the connection diagrams on the
following pages for detailed information regarding these
connections. Make connections to these jacks only as
shown in the diagrams. If these jacks are used in any other
manner, e.g., to control electric screens, the unit can be
damaged and the warranty will be void. For specific electrical
information on these jacks, contact JBL Synthesis
Customer Service at 516.255.4JBL.
Do not plug anything into these jacks if you
are not using the S5160 with a JBL Synthesis
system.
9. Speaker Mode Control Connectors
The front left and front right speakers are switched
between Music and Cinema modes by signals present
at both the DIN connectors (as described in Section 8)
AND the two-conductor connectors shown at
ª
.
The installer may find it preferable to use two-conductor
wire (18-gauge recommended) rather than long multi-
conductor DIN cables for the mode-switching connection
between the S5160 and these two speakers. Adaptors
supplied with the S5160 are used at the speaker end of
the wire to allow connection to the speakers’ DIN input
connectors. Proper polarity must be observed, as shown in
the wiring diagrams; reverse the connections at one end of
the wire if the speaker(s) do not switch modes – from
horn (Cinema) to tweeter (Music).
Note that five-conductor DIN cables MUST be used
between all other components to allow correct power and
mode switching, and that the same warning not to plug
anything into these jacks if you are not using the S5160
with a JBL Synthesis system applies here; do not attempt
to use these jacks to control anything other than the
mode-switching function of JBL Synthesis speakers, as
this may damage the S5160 and will void the warranty.
10. AC Inlet
Your S5160 is shipped with an IEC-type removable power
cord that mates with the AC inlet on the rear panel. To
ensure proper operation, use the supplied power cord.
This amplifier is NOT a multivoltage unit; using a
power cord that is not compatible with a 120V, 60Hz AC
wall receptacle will void the warranty.
