ACOUSTIC FINE TUNING

Each HDLCRbx loudspeaker features separate Treble Cut and Dialog Enhance controls on the rear for acoustic fine-tuning after placement, as shown in Figure 4. Adjust these controls as follows:

•Initially set Treble Cut to Flat and Dialog Enhance to Normal.

•If a HDLCRbx is placed in a room with highly reflective surfaces like glass or tile or the reproduced sound is too bright, set the Treble Cut switch to – 3 dB to lower the high- frequency response.

•Listen to dialog being reproduced on the HDLCRbx. If you want it more pronounced, set the Dialog Enhance switch to Enhance to boost the mid-frequency response.

CHECKING LOUDSPEAKER PHASE

Loudspeaker wire has two conductors. On both your loudspeaker and amplifier, one conductor is attached to the negative (–) terminals, while the other is attached to the positive (+) terminals. Usually, the wire is marked for your convenience, but the marking can be done in the following different ways:

•Stripe on one wire

•Ribbed area you can feel on one conductor

•Different colors of metal wire on each conductor

•Fabric strand or string wound into one of the conductors
