Emotiva USP-1 - Manual (Page 14)

Bass Management – Low Pass/High Pass Filters
The USP-1 offers a full range speaker
connection, as well as offering a bass
management system that allows you to optimize
your sound when using a powered
14
subwoofer.
Bass Management Close-up:
1. Low Pass filter frequency control
2. Balanced (XLR) subwoofer output
3. RCA subwoofer output
4. High Pass filter frequency control
5. High Pass left and right speaker outputs
6. Full Range left and right speaker outputs
Full Range Outputs
Conventional stereo, 2 channel outputs. When
using the Full Range outputs (6), the speakers
receive full frequency range.
Full Range frequency response: 5Hz - 80kHz full range outputs, with less than 0.05dB of deviation.
Low Pass/High Pass Outputs
When using the Low Pass and /or High Pass outputs, a crossover is engaged for the subwoofer (Low
Pass), and for the left and right speakers (High Pass). Both filters have a rotary frequency control
selector which sets the frequency of the crossover, from 50Hz to 250Hz (12dB per octave slope).
Full Range and High Pass/Low Pass modes work simultaneously. This allows for several possible
combinations:
1. Full Range only
2. Full Range plus Low Pass (adding a subwoofer)
3. High Pass/Low Pass
There is no ‘wrong way’ or ‘right way’ to use these settings – it’s all about what sounds good to you, and
what works best with your speakers.
Full Range Only:
Recommended for users with full range speakers that are capable of producing full bass tones.
Use the Full Range outputs (6) for full range speakers.
Full Range Plus Low Pass:
Recommended for users who like the sound of their full range speakers using all frequencies, but want to
add more bass to the mix using a subwoofer.
Use the Full Range outputs (6) for the left and right side speakers, and use either the Balanced (2) or
RCA (3) subwoofer outputs. The Low Pass filter frequency control selects the frequency where the
subwoofer is added to the mix. It is recommended to start at 80Hz (shown in the Bass Management
diagram, in the 11:00 position), and then adjust either towards a higher or lower frequency, until you are
satisfied with the result.
