Connections
The 160SL is connected for operation using the rear panel XLR connectors. Note that the two rear panel input
sections have a push-switch which lifts the contact on pin #1 (ground). Keep this switch in the OFF position (pin
#1 connected) until all connections are made. Be sure that your input and output cables are wired in the “pin
2-hot” configuration, which is printed on the rear panel of the 160SL. For more information on other types of
connections, refer to the section entitled Operating Notes.
When connecting the 160SL, refer to the following steps:
• Turn OFF all equipment BEFORE making any connections.
• Mount the 160SL in a 2U rack space. (Optional)
The 160SL requires a two rack-space height and a standard 19 inch rack-space width. It can be
mounted above or below anything that doesn’t create excessive heat, since it requires no special
ventilation. Ambient temperatures should not exceed 113°F (45°C) when equipment
is powered.
Caution: Never remove the cover. There are no user serviceable parts inside.
• Make connections via XLR connectors.
• Plug in AC power cable and power ON the unit.
Note: Check the line voltage printed on the rear panel of the 160SL and verify that it is correct for your area.
Two Basic Compressor Setups:
A: Channel One shows processing of a group
or aux main output. Signal goes to the 160SL
input from the output/insert send of the
console, and returns to the console via the
input/insert return of the same group/aux
on the console.
B: Channel Two shows connections for
processing a signal from a single channel.
Input of the 160SL is fed by the channel insert
output/send, and returns to the console via
the insert input/return.
