XSP-1
10. High Pass Crossover Frequency Adjustment
Adjusts the cut-off frequency for the High Pass filter on the Main Outputs. Fully counter-
clockwise corresponds to 50 Hz; fully clockwise corresponds to 250 Hz.
11. Low Pass Crossover Frequency Adjustment
Adjusts the cut-off frequency for the Low Pass filter on the Subwoofer Outputs. Fully
counter-clockwise corresponds to 50 Hz; fully clockwise corresponds to 250 Hz.
Note: Combining the bass management on the XSP-1 with other bass management
(like the crossover settings on some subwoofers) is usually not recommended.
If you’re using the bass management on the XSP-1, you will usually get the best
results by setting your subwoofer to “flat” or “direct” if possible.
12. Full Range / Low Pass Selector (for Subwoofer Outputs)
To make the Subwoofer Outputs of the XSP-1 full range (and disable bass management
for the Subwoofer Outputs), set this switch to the right (away from the Low Pass
adjustment screw). Setting this switch to the left (towards the adjustment screw) enables
bass management for the Subwoofer Outputs. When bass management is enabled, the
Subwoofer Outputs carry only the low frequency part of the audio spectrum (the crossover
point is set using the Low Pass adjustment (11)).
The Subwoofer Summed Output provides a signal that is a sum of the Left and Right
Subwoofer Outputs, and is appropriate for use with a single subwoofer. Some subwoofers
include internal (and non-defeatable) bass management, and so work best with a full range
signal for their input.
When the HT Bypass (Home Theater Bypass) mode is enabled, all three of the Subwoofer
Outputs carry buffered copies of the signal received at the Home Theater Sub Input (the
signal is reduced by 3 dB on the Left and Right Outputs).
Note: To set the XSP-1 for “full bass management”, set both switches towards the
center (towards each other).
Note: The High Pass and Low Pass crossover points are typically set to the same
frequency for smoothest blending of high and low frequency bands, but this may not
be optimum in all systems.
13. IR In and IR Out
The IR Input is used to allow IR control of the XSP-1 even if it’s located inside a cabinet or
in another room, and accepts the output of most standard IR receiver modules.
The IR Output repeats the signal received by the IR Input (and the receiver on the
front panel of the XSP-1), and so can be used to “repeat” an IR control signal to other
components within range of the XSP-1.
