5. Subwoofer Outputs
These outputs are provided to allow you to connect one or two powered subwoofers to your BasX
PT-100. Both of these outputs deliver the same line level signal, which is the sum of the two audio
channels on the PT-100 (monaural summed signal). This signal is full range, and is intended to be
used with one or two subwoofers which include their own low pass filters and level controls. This
signal could also be used to feed a separate center-channel speaker.
Note: The PT-100 doesn’t include internal bass management filters. The signal coming from the
Subwoofer Outputs is a summed, monaural, full range signal. You are expected to use the level
and filter controls on your subwoofer(s) to match the levels of your sub(s) to the levels of your
main speakers, and to apply low-pass filtering to prevent the range of frequencies produced
by your subwoofers from overlapping those produced by your main speakers. Most modern
subwoofers include these controls; refer to your subwoofer’s instructions for more details.
6. Main Outputs
These outputs are the main stereo outputs on your PT-100. They should be connected to the
unbalanced input on your power amplifier. These outputs provide a standard level signal which
is compatible with virtually all audio power amplifiers (or a line level input on a preamp or
integrated amplifier).
7. FM Antenna Input
Connect an FM Antenna to this input to allow the FM tuner to receive FM radio stations. The
included FM antenna will provide reasonable reception in strong signal areas.
Note: Connecting an external FM antenna to your PT-100 will usually allow you to receive more
FM stations, and improve the signal strength on weak stations. You will also find that changing
the position and orientation of the antenna will often have significant effect on how many
distant stations you receive, and on the strength and signal quality of even local stations.
8. Digital Audio Inputs
The PT-100 provides several different digital audio inputs to accommodate a variety of digital
audio sources.
• The Coax input accepts PCM electrical S/PDIF digital audio signals up to 24/192k. This input is
often used to connect the digital audio output from a CD player or Blu-Ray disc player.
• The Optical input accepts PCM optical S/PDIF digital audio signals - often referred to as Toslink
- up to 24/192k. This input is used to connect the Toslink output from a TV, disc player, or
media player.
• The asynchronous USB input accepts digital audio from a computer or other digital audio
source that supports USB. It supports standard PCM digital audio up to 24/96k.
