TRx3210 Pin Flip Switch (Full Range Operation)
Carvin TRx3210 loudspeakers come with a speaker pin flip switch. In full range/passive mode, this switch
allows the user to select operation from either pins 1+ & 1- (standard) or pins 2+ & 2-. This can significantly
simplify speaker cable runs by half with 4-pin TwistLoc cables. Below is an example of how the pin flip switch
is used.
Remove rubber plug marked NORMAL/ PIN FLIP from connection panel. Using a small flat-head screw
driver, carefully insert screwdriver into opening and slide switch to the down position for Pin Flip operation.
This will enable use of pin 2+ & 2- to drive this speaker module. Note: pins 1+ & 1- will be no longer used in
this cabinet. Replace rubber plug after change.
When using the PIN FLIP feature, you must switch to
FULL RANGE mode.
