Control Settings and Connecting Your TR-1D / TR-3D
TR-1D / TR-3D’s built-in High Pass 100Hz crossover. Use care in this instance because you’ll be driving
the satellite speakers full range, risking overdriving their woofers and/or clipping the amplifier.
The 100Hz filter mentioned above allows bass management at speaker level. The built-in filter subtracts
bass below 100Hz from your satellite speakers and should be used if your receiver or amplifier lacks bass
management and you don’t want to run the satellites full range. Running very small satellite speakers at
high levels, full range, risks damaging them. Since you now have a subwoofer take the burden of trying
to reproduce deep bass off the satellites and let the sub handle it. (generally recommended).
In such a hookup, connect the speaker wires from your amplifier/receivers’ speaker output connectors to
the TR-1D / TR-3D High Level In binding posts, then connect another set of speaker wires from the
subwoofer’s corresponding channel High Level Out terminals to the input terminals of the appropriate
speaker. Remember to set the subwoofer Crossover control to 100Hz to match the internal variable
low-pass to the fixed high-pass.
Bass Equalization: This control selects between 0, +3dB and +6dB. Adjust for the best bass
performance in your room, keeping in mind that the primary goal should not just be more bass––
quantity is not always quality. Ideally, the transition between sub and main speakers should remain
seamless and inaudible. If you can identify the location and presence of the TR-1D / TR-3D, your
subwoofer volume, the crossover point, or the EQ is probably set too high (or some combination of
the three).
Phase: This switch adjusts the relative phase between the subwoofer and main speakers. This is set
properly when the subwoofer plays most evenly and fully for any given setting of its level control with a
smooth crossover transition to the satellite speakers. The easiest way to test this is in the prime listening
seat while someone else alters the phase control setting. Use either a test-tone generator (there are free
software tone generators available online that let you use your computer to produce test tones), test
tones from a test CD/DVD, or music that has bass that runs up and down the scale from deep bass to
mid-bass. In particular, pay attention to the transition from the subwoofer to the satellites with the
Phase switch in both positions.
AC Line Cord: This supplies power to the TR-1D / TR-3D’s internal electronics. The TR-1D / TR-3D must
be plugged in to the proper power 110/220 receptacle in order to operate properly.
