70v in-line distributed audio systems generally require less cable gauge than standard 4/6/8 Ohm
systems. However some attention should be paid to the cable type vs speakers used to obtain the right
output. Note the general recommendations below:

Please carefully select the receiver amplifier input side or “IN Amplifier” side of the TIC SP70vTA
transformer and remove the screw cap. Insert your cable from the amplifier being careful not to lose
or misplace the waterproof “O ring” or washer seal. Strip about half inch of insulation from the positive
and negative/ common cables and screw connect accordingly. Re-tighten the screw/ seal over the
cable to complete that connection. See picture below:
