TDT50 & TDT150 INSTALLATION INSTRUCTIONS

Disconnect AC power from the amplifier.
Remove the amplifier top panel by removing 17 screws (6 on each side, 3 on back and 2 on front).
Please note that front screws are longer.
If the mounting bolts have two nuts, remove one and save. These nuts will be used to hold the transformers in place. If the mounting bolts have only one nut, do not remove. Transformer will be held in place with supplied nut.
Install transformers as shown in figure 1.
Locate the amplifier circuit boards and jumpers.
Each amplifier card represents two individual output channels; one odd and one even (refer to figure 2 for reference).
Using a pair of pliers, remove the black and red jumper from the associated amplifier channel.
Following the diagram below (figure 3), connect the wires as indicated.
Please note that wires on odd channel are mirrored from wires on even channel.
Replace amplifier top panel (longer screws go on the front).
Assign channel HPF (High Pass Filter) by flipping the appropriate channel rear panel dip switch. (figure 4)
Apply appropriate rear panel “xfmr” voltage sticker. (figure 5)
