Bass Management; Speaker Setup - Emotiva UMC-1 Operation Manual

BASS MANAGEMENT

Unlike higher frequencies, it is difficult to discern exactly which direction lower bass is coming. The UMC-1 has a bass
management system which takes advantage of this effect. It allows you to choose whether your speakers will play the
full frequency range or if the bass will be redirected to the subwoofer. The advantages of redirecting the bass to a
subwoofer include the following:
The overall bass of the system is improved as subwoofers are specially designed for this frequency range.

The subwoofer can simultaneously play the bass from all the speakers, in addition to its own low frequency

effects channel (LFE).
There is no loss in perception of the position of movie or music sound effects, as the ear cannot easily locate

the position of low frequency sources.
Smaller speakers can be used for main front, center and surround, as they do not have to reproduce the low

frequency range. This leads to a saving in speaker expense and room space.
Your amplifiers do not waste power reproducing the low frequency range when using a powered subwoofer.

Nearly all home audio subwoofers are self powered.
The Emo-Q room correction and speaker setup system will set all your speaker sizes, distances and crossovers.

These can also be set manually to tailor the settings to your specific needs.
Dolby Digital and DTS modes are designed especially for complete systems with front, center, and surround

speakers and subwoofers. You need all of the speakers to get the best performance from your Home Theater.
If you do not have a subwoofer connected, then you should not use the bass management system (so set all of
the speakers to Large). Without a subwoofer, you will be missing the 5.1 LFE (low frequency effects)
information.
Note: A subwoofer is required if the front speakers are set to SMALL.

LEVEL CALIBRATION
•
This is where you use the test tones to set the volume levels of your speakers and subwoofer. Emotiva recommends
using a high quality SPL (Sound Pressure Level) Meter for this step. (Use this selection for manual set up only. Emo-Q
will set the levels for you).
First set your sound level meter at your approximate ear level where you normally sit. Follow the instructions that came
with your SPL Meter for optimum LEVEL CALIBRATION
To do this, manually press the MENU button on the Remote Control. From the MAIN MENU scroll to SETUP, press
ENTER. When the SYSTEM SETUP menu appears scroll to SPEAKER SETUP, press enter again. When the SPEAKER SETUP
menu appears press enter when LEVEL CALIBRATION is highlighted.
