Audio Adjustment <Network>

Filter Adjustment <FTR> (Open state)

The following adjustments can be made during filter adjustments. Make the appropriate adjustments for the reproduced frequency band and characteristics of the connected speaker unit.

Filter frequency adjustment: Every 1/3 octave

Level adjustment: 0.5 dB/1 step

The cut-off frequencies of the high pass filter (H.P.F.) and the low pass filter (L.P.F.) of each band (subwoofer, low, mid, high) and the reproduction level of each band are set up.

Range	Cut-off frequency	Cut-off frequency	Level adjustment
	of H.P.F.	of L.P.F.	range
Subwoofer-range	20 Hz — 100 Hz	25 Hz — 250 Hz	–24	— +10 dB
Low-range	25 Hz — 250 Hz	250 Hz — 10 kHz	–24	— 0 dB
Mid-range	200 Hz — 10 kHz	2 kHz — 20 kHz	–24	— 0 dB
High-range	1.6 kHz — 20 kHz	8 kHz — 20 kHz	–24	— 0 dB

Slope adjustment: PASS, –6 dB/oct. — –36 dB/oct. (Every –6 dB/oct., total of 6 steps)

The slope (inclination of attenuation of filter characteristics) of H.P.F. and L.P.F. is set up.

Note:

•When the slope is set as PASS, the audio signals bypass the filter circuit, cutting out the effect of the filter circuit.

•In order to protect the speaker unit, H.P.F. has no PASS set up for high ranges.

•In order to protect the speaker unit, H.P.F. has no PASS set up for mid-range, however you can set to PASS by changing the settings (refer to page 36, step 8).
