'Input Name' (1)

Local name of the analog audio input.

'Input Mode' (2)

Specification of the gain level structure of the analog audio input.


The microphone pre-amp is activated, and the input gain is pre-set to a level of +30 dB.


The input gain is set to the line level. Presetting: 0 dB


This analog audio input is not used.


Activates the analog audio input and switches back to the latest gain level setting ('Mic/Level').

Use 'ON' and 'OFF' to switch the analog audio input quickly without changing the selected input gain.

When microphones PT1002, PT2003, PT2008 or PT2009 are connected to analog audio inputs, select always the 'Line' level 'Input Mode'.

That ensures high audio quality and similar audio input level when switch between the microphones.

'Gain' (2)

Set the gain of the input signal.

'Phantom Power' (2)

Optional activation of the phantom power of an analog audio input. For example, the microphone of the PT2001 desk call station requires phantom power.

'Controlled By' (3)

It is possible to control the input volume from an external source.

'Extern 1…8'

The gain is controlled via the analog control input of an external 0...10 V source. For example, you could use a potentiometer that is connected directly to the analog control input of the local station.

'Preset 1…8'

The gain value is specified by Preset 1…4

'AudioCtrl 1…8'

Reserved for future use.

'Rval 1…8'

Reserved for future use.

Compressor/Limiter (4)

For each channel the following parameters are configurable:

Enable or disable

  • Limiter
  • Compressor/Limiter

'Thres (Threshold)' (4)

If the input signal level rises above the threshold value, the compressor will activate.

You will find more information on how to configure the compressor in chapter ''Compressor/Limiter' tab (20).'

'Ratio' (4)

Define the compression ratio of the compressor.

  • Ratio 1:1 -> no compression,
  • Ratio 1:2 -> 50% compression of the part of the signal exceeding the threshold

Example of analog audio input 3:

  • Compressor Threshold = -20 dB, Ratio = 1:2
  • Input levels below -20 dB are not affected
    • Example input -30 dB -> output -30 dB
  • Input levels above -20 dB will be compressed by 1:2
  • Example
    • input level 0 dB
    • output level = compressor threshold + compressed value
    • input level 0 dB -> 20 dB above -20 dB, (compressor threshold)
    • 20 dB compressed by 1:2 -> 20 dB / 2 = 10 dB (compressed value)
    • output level = – 20 dB + 10 dB = -10 dB

Limiter (20) see 'Compressor/Limiter' tab (20)

Output levels above 5 dB are set to 5 dB

'Feed Network with' (5)

Define the feeding behaviour of the program channel at the ‘PACE-Net’ network.


this input is not used to feed into the network


always feed the selected network channel

Triggered signal

only feed the network channel if the input level is above the triggered signal threshold (21)

<test signal>

feed a testsignal. The waveform, frequency, and sound level settings can be configured in the 'Test Signal settings' area.

Note: ‘Triggered Signal’

Only network channels are affected by the triggered signal setting to reduce the data rate at the “PACE-Net” network.

Local channels of this station are not affected by this setting.

Network channel No // program channel or priority channel (6)

This number identifies a network channel. The number must be unique within the system.

Available feeds are displayed on the 'Audio Feeds' tab. Feeds with a number 128…255 will be upgraded automatically to priority channels, which are used exclusively for call station functionality.

Network channel number
Press the up/down arrow to select the next available channel number.

Double click the channel number to clear it. In the above graphic, the number is 50.

'of default AudioGroup' (6)

Reserved for future use.

'Network Channel Name' (7)

Global name of the feeding channel.

'Keypad' (24)

A keypad function is configured for analog audio input 1.

The ‘Keypad’ button is only displayed if a keypad function is configured for analog audio input 1.

'AVC' (25)

The AVC function is enabled for analog audio input 4.

The ‘AVC’ button is only displayed if the AVC function is enabled.

See 'Automatic Volume Control' (AVC) settings (22).
