 APF (All Pass Filter)

This filter modifies only the phase, passing the signal at all frequencies. This is mainly used to correct the

phase at the crossover band. APF 1st will invert the phase at the specified frequency by 90° and for entire

frequency bands by 0°–180°, while APF 2nd will invert the phase at the specified frequency by 180° and

for entire frequency bands by 0°–360°. For APF 2nd, you can adjust the Q setting.

 Horn EQ

CD (Constant Directivity) horn speakers have the characteristic of rolling-off the level of the high-fre-

quency range. Horn EQ is an equalizer that compensates for this characteristic. For this reason, the Gain is

limited to 0 dB or higher, and the Frequency is limited to 500 Hz or higher.

 Delay

Here you can specify a delay for the signal. The delay time can be specified in units of milliseconds, samples,

meters, or feet. This is provided at two locations; in the input section and in the Speaker Processor.

• Delay Scale does not support parameter link.

Parameter Range Function

q Delay

ms: 0–500

(0–1,300 for the input section)

SAMPLE: This will depend on the

sampling frequency.

METER: 0–171.8

(0–446.7 for the input section)

FEET: 0–563.6

(0–1465.4 for the input section)

Specifies the delay time.

There are two edit boxes; the upper shows milli-

seconds, and the lower shows the units selected

by [Delay Scale].

w ON On/Off Turns the delay on/off.

e Delay Scale

SAMPLE

METER

FEET

Selects the units in which the delay time is speci-

fied. The selected button will light, and the units

will change for the lower of the [Delay] edit boxes.
