NILES AUDIO CORPORATION – 1-800-BUY-HIFI
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.
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.
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.
