Niles Audio Speaker manual Setting the DIRECT/DIFFUSE Sound Field Balance, Acoustic Fine Tuning

SETTING THE DIRECT/DIFFUSE SOUND FIELD BALANCE

Each HDFX also includes a companion FX/CUT control (see Figure 18) that allows adjustment of the direct/diffuse sound field balance to provide realistic effects regardless of room size.

In large rooms (where the loudspeakers are farther away from the listening position), use the FX setting for a more direct sound.

In small rooms, use the CUT setting for a more diffuse sound.

Figure 18. The HDFX includes BIPOLE/DIPOLE and FX/CUT controls.

ACOUSTIC FINE TUNING

Each HDFX loudspeaker features separate, baffle-mounted TREBLE/CUT and BASS/CUT controls for acoustic fine-tuning after installation, as shown in Figure 19.

If an HDFX is placed near a boundary, use the CUT setting to lower the bass response by 3 dB.

If an HDFX is placed in a room with highly reflective surfaces like glass or tile, use the CUT setting to lower the high-frequency response by 3 dB.

Figure 19. The HDFX features TREBLE/CUT and BASS/CUT controls.

INSTALLING THE GRILLE

At each loudspeaker, carefully fit the grille into its recess so that it is barely in place. Starting with one corner, gently press the grille around the loudspeaker, pushing it in a little bit each time. Be gentle – the aluminum grille can be easily bent out of shape. When properly installed, the grille will be absolutely flush in appearance with the surrounding frame.
