User Manual
• For dierenal (i.e. fully balanced) ampliers using one REL, simply use the standard connecng scheme
with the excepon of NOT connecng the black wire to a negave speaker terminal. Instead, it should
rst be allowed to “oat” or hang down without connecon to ANY terminal. Should hum occur using this
method, please try connecng to an unused RCA connector on the rear of a preamp or amplier. Please
contact your dealer should there be any quesons concerning this or any other hookup procedure.
NOTE: 212/SX models are equipped with internal circuitry to allow connecon to many Class D (digital) ampliers.
Warning: Do NOT connect the Black wire to the main Class D power amplier’s speaker ground terminal.
Some Class D ampliers produce posive voltage at the amplier’s speaker ground terminal (black) and
connecng the REL’s ground will produce an undesirable shorng to ground. If connecng to
a Class D amplier, follow the above connecon procedure for dierenal ampliers.
