5) Input gain level knob

You can set the input signal level depending on the

connected audio source to reach the optimal output level.

You can check the output level on the Output level meter

(5). If Dante input is selected you can adjust the level of

Dante signal.

6) High Pass Filter switch

You can turn ON the HPF to eliminate low frequency

disturbances like pops or microphone handling noise. The

cut-off frequency of the HPF is 160Hz. It is very handy for

speech. If you need to distribute the music or full-range

signals it is handy to have the HPF switched off.

7) Compressor/Limiter switch

If you need to reduce the dynamics of the input signal

and/or be sure that the output signal will not be higher

than the nominal output level please switch this button

ON. Function of the compressor and limiter you can see

on the Gain reduction level meter (6). It is very good for

speech.

8) PFL button

To check your levels only for one input, push this button

and you can see the level of output for corresponding

input. You can easily see if all microphones have the good

output levels and identify, if some of the microphones are

too loud or too silent in the output.

9) Microphone level indicator bar

You can visually monitor the level of each microphone

output signal in 5-segment output indicator bar with signal

clip LED. If this red light is flashing you should reduce the

gain of the microphone.

10) Gain Reduction indicator bar

If Comp switch is set to ON, you can visually monitor the

level of Gain reduction on this 4-segment indicator bar.

11) Routing switch

Each microphone could be routed to 2 separated groups

or to both groups at the same time. This is useful, if you

have two (or four) lecterns and you want to route signal

from each microphone (or group of 2 microphones) to

separated tracks. Reporters can edit the recording easily,

if they have both lecterns on separated tracks. You can

label the outputs in the output extender with names of

the lecterns or groups and reporters easily decide which

group output they want to use.

12) Test signal oscillator operation switch

To test signal level, which is coming to the outputs, you

can switch this Test 1,6 kHz sine signal oscillator on.

After recipients set the levels in their recording devices,

you should switch this function OFF. When compressor

switch is set to ON, output signal level won't exceed this

maximum output level.

13) Global group output level indicators

You can check output levels of each group individually

here in 7-segment level indication bar.

14) AFL button

You can check output levels of each group individually

here in 7-segment level indication bar.

15) Headphones output connector

If you want to monitor the output by your headphones,

you can plug them to this connector (6.3 TRS/Jack stereo

connector).

16) Headphones output level knob

If you have your headphones plugged in, you can adjust

the level of monitoring the output by turning this knob to

set your comfort hearing level. Please be careful when

setting the levels, too high monitoring volumes can

damage your hearing ability!

17) Power ON indicator

When AudioPressBox® is turned on, this indicator lights up.

18) Power switch

With the power switch, you can turn your AudioPressBox®

ON or OFF.

19) Group A Mic/Line Outputs 1-24 + Group B Mic/

Line Outputs 1-24

Mic level output XLR connectors – every output is

individually transformer isolated.

20) Mic/Line level select switch

You can set if you want to get Mic (-20dBu) or Line (+6dBu)

level from individual output

21) Power supply connector

Plug the mains cable to AudioPressBox® here.
