Legacy FOCUS SE - Fine Tuning; Treble Trim Adjustment; Bass Trim Adjustment

22
To facilitate proper set-up of your speakers in a variety of room situations,
we have included several heavy duty toggle switches on the terminal plate,
located on the back of the loudspeaker. All switches in the “up” position
represent the “anechoic flat” position.
TREBLE Trim: - Nominally flat in the up position
-
Negative 2dB at 10 kHz in the down position
(shelving for brighter rooms)
BASS Trim: - Nominally flat in the up position
-
Negative 2dB at 60 Hz in the down position
(also raises impedance for budget receivers)
