Parametric EQ

AllSonanceDSPampliermodelsfeaturea10bandparametric

EQ. Adjustments made to the EQ will be displayed on the output

frequency response graph. We strongly suggest not adjusting the

EQ without proper measurement equipment.

EQ Frequency Hz

be adjusted.

EQ-Q

This setting determines the width of the adjustment range.

The lower the number the wider the bandwidth. The higher the

number the narrower the bandwidth.

EQ-Gain +/- dB

Thelevelofeachparametricadjustmentcanbeset+/-12dB.

Careful adjustment of the EQ gain is necessary to prevent damage

to the speakers. Always increase the level as little as possible.

the target frequency response.

Delay

Delay is shown in milliseconds, feet and meters. You can make an

entryinanyofthethreeeldsandtheothereldswillbecalculated

automatically. The minimum delay is .01 milliseconds, the maximum

delay is 12 milliseconds. This function is useful when compensating

for distance between satellites and subwoofers for instance.

Tilt Control

The tilt controls are very sophisticated bass and treble control.

By selecting a start frequency and level you can ramp the bass and

ortrebleupordown.Theeectofthetiltcontrolisvisibleinthe

Low Tilt/High Tilt

Thissettingturnsthelowandhightiltcontrolsonando.

Frequency

Enter the start frequency of the tilt in Hz. To boost the low

frequencies you would typically set the low tilt to 100Hz. To boost

the high frequencies you would set the high tilt to around 5kHz.

Gain

Thegaincanbesetin1dBsteps+/-12dB.Whensettingthegain

use as little positive gain as possible to minimize the risk of damage

to the loudspeakers.

Filter Type

6dB,12dB,18dBand24dBperoctaveButterworthltersare

available in the pull down menu. The higher the number the faster

the speakers output will be reduced below or above the crossover

frequency. In a typical satellite subwoofer system the crossover

frequency would be around 80-100Hz for both the high and low

passlters.

All of the above output power ratings are when connected to an 8

Ohm load.
