Filter

In this menu you can assign a frequency

band to the connected speakers that

corresponds to their recommended

operating range. The screen is subdivided

into three: Front, Rear and Subwoofer. In

each area, in the left half you can set the

crossover frequency of the high pass filter

as well as its Q factor (dB/Oct.). In the

right half are the crossover frequency and

Q-factor of the low pass filter. The blue line

shows the set slope of the filter. „Bypass"

means that the signal is unfiltered and

contains all frequencies.

The filter settings also apply to the

corresponding preamp outputs.

When you have done the preferences,

go back to the main menu, and touch the

„Save to Amplifier" button

to transfer

the preferences to the amplifier. During

the saving process do not switch off the

amplifier as this may lead to malfunction

and/or damage. You can also save the

preferences on your smartphone. To do

this, press the „Save on Phone" button

, and enter the desired filename.

Time Alignment

In this menu you can apply a time delay to the speaker signal to simulate an ideal listening

position.

You can call a help menu at the top right corner of this menu. Note the distance between

your listening position and each speaker. Choose the most distant speaker as the refer-

ence for the other speakers.

With the aid of the following example, calculate the values for your speakers:

(FL)

front left is

0.80 m from the listening position

(FR)

front right is 1.40 m from the listening position

(RL)

rear left is

0.50 m from the listening position

(RR)

rear right is

1.30 m from the listening position

(SubW) subwoofer is 2.00 m from the listening position

Value for FL = SubW – FL

→ FL = 2.00 – 0.80 m

Value for FR = SubW – FR → FL = 2.00 – 1.40 m

Value for RL = SubW – RL → RL = 2.00 – 0.50 m

Value for RR = SubW – RR → RR = 2.00 – 1.30 m

SubW remains at the value „0"

When you have done the preferences, go back to the main menu, and touch the „Save to

the Amplifier" button

to transfer the preferences to the amplifier. During the saving

process do not switch off the amplifier as this may lead to malfunction and/or damage.

You can also save the preferences on your smartphone. To do this, press the „Save on

Phone" button

, and enter the desired filename.
