Input Connections - Samson RSX115 Owner's Manual

Input Connections

The RSX has a pair ¼" (TS) phone and Speakon® connectors wired in parallel. This enables you
to directly connect an extension cabinet to an RSX speaker.
Only use one ¼" or Speakon® connector as an input connector from an amplifier. Typically, you
will only connect a single extension cabinet to an RSX cabinet, but it is possible to daisy-chain
multiple cabinets. When wiring multiple cabinets in parallel, attention must be paid to the over-
all impedance of the loudspeaker system, and the minimum load impedance of the amplifier.
Please see the chart below for typical impedance calculation for multiple speaker arrangements.
It is recommended, especially for installation applications, to use Speakon® style connectors
because they lock into jacks providing a secure connection, are able to handle high current, and
the contacts do not cause a momentary short when connecting to an amplifier or speaker cabi-
net.

Typical Impedance Calculations
16Ω + 16Ω = 8Ω
8Ω + 16Ω = 5.3Ω
8Ω + 8Ω = 4Ω
8Ω + 16Ω + 16Ω = 4Ω
16Ω + 16Ω + 16Ω + 16Ω = 4Ω
4Ω + 8Ω = 2.7Ω
4Ω + 4Ω = 2Ω
