SubwooferCongurationandAdjustment

The Emotiva X-Ref 10 includes an advanced DSP Management System, which is

accessed via a push-to-engage rotary encoder. The results are displayed on a back lit

LCD display, which remains lit while conguration is in progress, but switches off after

a short time when not in use; a press of the encoder button turns the display back on.

The diagram on Page 18 of this manual shows the complete Menu system of the X-Ref

10.

Conguring the Crossover settings

When the X-Ref 10 is connected to a preamp or pre/processor that includes bass

management, the X-Ref 10 X-Over (crossover) setting should be set to Direct. When

connected to a source that does not prevent high-frequencies from being sent to the

subwoofer, set the crossover frequency to obtain a smooth blend between the X-Ref 10

and your main speakers.

Adjusting the Volume setting

The Volume should be set so that the sound produced by the subwoofer blends with

your music rather than standing out from it. Your music should have deep, clean, solid

bass, and movie effects should have the impact and punch that you want, but you

shouldn’t actually hear the subwoofer as a source of sound.

Adjusting the Phase setting

The Phase setting is used to match the phase of the X-Ref 10 with your main speakers,

and any other subwoofers you have installed, to prevent cancellation effects in the

range of frequencies produced by both. Adjust the Phase setting to produce the most

overall output in the frequency range where the X-Ref 10 overlaps with other speakers.

Conguring the Preset setting

The Music (Flat) Preset on the X-Ref 10 offers at frequency response (except as

modied by the EQ settings), while the Movie Preset adds about 6 dB of bass boost at

45 Hz. In a typical installation, the X-Ref 10 is congured with the Music Preset as the

default, and a trigger output from your pre/processor is attached to the X-Ref’s Movie

EQ Trigger input. Music is played using the Music (Flat) Preset, while the trigger from

your pre/processor switches the X-Ref 10 to the Movie preset for movies.

Adjusting the Equalization settings

The X-Ref 10 offers two separate bands of full parametric equalization to correct for

variations in room response and allow you to match the response of your X-Ref 10

perfectly to any main speakers. Each parametric equalizer section allows you to set

a center frequency (Frequency), and a lter bandwidth (Q), and then adjust the gain

of only that band of frequencies up or down. A higher value for Q corresponds to a

narrower range of affected frequencies. Each EQ can be used to boost or reduce a

specic band if required, for example to eliminate a troublesome room resonance.
