Frequently Asked Questions - AFM-20DSP-AEC Kramer

How do I connect to the AFM-20DSP-AEC via Ethernet?

Connect a straight-through or crossover cable from your PC to the ETHERNET RJ-45 port on the rear panel. By default, DHCP is enabled. If direct connection, set your PC to a static IP in the range 192.168.1.x (excluding 192.168.1.39). Open a web browser and enter the device IP (default 192.168.1.39). Log in with username Admin and password Admin.

How do I configure Acoustic Echo Cancellation (AEC) for a conference call?

Connect a microphone to an analog input (e.g., port 1). In the DSP webpage, enable AEC Mic for that input and click AEC. Set the Far Side Input Selector to the digital input (e.g., USB_B) that receives the remote audio. Enable Echo Cancelling and adjust parameters like Noise Reduction and Comfort Noise Level as needed. Route the microphone input to outputs via the Matrix page.

How do I route audio inputs to outputs?

In the embedded webpages, go to the Matrix page. Click a cross-point between an input and an output to create a route (turns green). To set volume, click the cross-point volume area and adjust the knob. You can route multiple inputs to the same output or one input to multiple outputs.

What I/O configurations are available?

The device supports seven analog I/O configurations: 16x4, 14x6, 12x8, 10x10, 8x12, 6x14, and 4x16. Select one in the A/V Settings page under I/O Config and click Set.

How do I reset the device to factory defaults?

Press and hold the RESET recessed button on the rear panel for about 5 seconds. This resets all settings to default parameters, including network configuration. Alternatively, use the web interface: go to Settings > Device Automation and select Reset to Factory.

How do I use the built-in power amplifier?

In the DSP or Matrix page, select which outputs to duplicate to the amplifier. Go to Duplicate to Amplifier Output and choose an output for Amp 1 (left) and Amp 2 (right). Connect speakers to the SPEAKER OUT terminal block: for Lo-Z stereo use L+/L- and R+/R-; for Hi-Z mono use Hi-Z and COM. In A/V Settings, select Hi-Z or Lo-Z and configure voltage (70V or 100V) for Hi-Z.

What is the default IP address?

The default IP address is 192.168.1.39. The device has DHCP enabled by default, so it may obtain a different IP from your network router. Check the connected router's DHCP client list or use a direct connection with static IP to find the device.

How do I link analog input or output pairs for stereo?

In the DSP page, click the link icon next to two adjacent ports (e.g., IN 7 and IN 8). When linked, adjustments made to one channel (like gain, EQ) are applied to both. This can also be done via the Matrix and Mixer pages.

How do I store and recall presets?

On the Mixer page, adjust settings then click Store and select a snapshot button (1-9). To recall, click the desired snapshot. For system presets, go to A/V Settings, choose a preset from the System Preset drop-down, and click Load or Save as. Presets can be locked via Protocol 3000 commands.

Input / Output Channels Operation

This section describes the function of the input and output sliders (the examples in this section, showing the inputs, apply also to outputs).

Note - In figures 21 and 22 below, meters (left side) display on a scale of -100 dBFS to 0 dBFS maximum (above this is clipping or audio saturation). On the right side, the gain level points to amplification for positive values and attenuation for negative values.

Level Measurement Indicators:

The audio signal enters the digital system at a certain level and is measured in dBFS units (dB relative to full scale, the maximum value).

• Maximum level indicator – shows the highest registered level (in RMS) and can change only if a higher level is detected. Click the indicator to reset to the current maximum value.
• 0dBFS – refers to the maximum signal level that can enter the system. signal levels higher than the system limit are clipped.
• Current maximum level indicator – displays the current maximum level and holds it until a higher value is detected.

Figure 21: Level Measurement Indicators

Gain/Attenuation Fader

• Maximum level – 15dB is the maximum gain.
• Unity gain – when volume fader is set to 0dB, the input level is not changed.
  • Volume fader – slide to increase or decrease the audio level.
• Minimum level – -100dB is the maximum attenuation.
• Current fader position – shows the current position of the fader. You can also type a volume level into this box and press Enter on your PC.

Defining AEC Settings

This section is for AFM-20DSP-AEC only.

AEC, Acoustic Echo Cancellation is used to cancel echo (or feedback) during conference calls. The AEC feature consists of one remote input and two individual microphone inputs. When AEC is enabled, it looks for the remote echo audio that was picked up by the individual microphone and then cancels the echoed audio in the microphone input. Besides removing the echo, AEC does Noise Reduction and Comfort Noise Generation.

Note - Far side input is configured into the AEC reference module. AEC module uses this Far side configuration as reference to remove echo from the microphones.

The steps below illustrate a typical conference call setup in which AEC is turned on to remove the Far Side echo. The microphone is connected to analog input port 1 ("MIC 1") and the digital input, USB, is connected to a computer with a speaker system.

To use the AEC:

1. From the Navigate List, select DSP.
2. Below Analog Inputs select the port to which the microphone is connected. In this screenshot, the microphone is connected to port "MIC 1":

Figure 51: MIC connected to analog IN 1

1. Select AEC Mic and then click AEC.

Figure 52: ACE Mic and AEC start up

The AEC Configuration window opens.

Figure 53: AEC Settings

1. Set the AEC settings based on the AEC parameters table below.

We recommend using the default settings. If you changed the default settings and later decide to return to the default settings, double-click the words Acoustic Echo Cancellation.

AEC Parameters Table:

Parameter	Description	Value
Echo Cancelling	Enables the AEC function. If this is disabled, the module does not perform any AEC functions and all mic inputs to the module are directly passed to the direct output of the module.	On/OffDefault: On
Noise Reduction	Enables Noise reduction on individual Mic Inputs. If this parameter is enabled, the noise reduction algorithm is applied to individual mic inputs and suppress the detected noise by the noise reduction level.	On/OffDefault: On
DC Filter	Removes DC	On/OffDefault: On
Noise Reduction Level	Set how many dB suppress the noise when Noise Reduction is enabled.	40 to 0Default: -10
Double Talk Echo Reduction	When both local end (mics) and far end (remote) audio sources are present at the same time, this is a Double Talk situation. Under this scenario an additional echo reduction algorithm is applied, and it uses the Double Talk Echo Reduction setting to configure the amount of echo to reduce.	-50 to 0Default: -6
Comfort Noise Generator	If enabled, a background comfort noise is generated and applied to the individual output if it is detected that the input mic is completely silent. This comfort noise is useful so that remote end user does not hear a complete silent channel and mistakenly think that the line has dropped.	On/OffDefault: On
Comfort Noise Level:	The noise level generated when Comfort Noise Generator is enabled. If you are mixing a lot of Mics before sending to the remote end, you must reduce this Comfort Noise level as all noise is summed before sending to remote end.	-60 to -30Default: -50.0
Delay	Delay to be applied to all Mic Inputs.	0 to 50Default: 0
Reset	Resets the AEC

1. Below Digital Inputs > click USB and select USB 1.1.

Figure 62: Input sent to Auto Mixer before going to the Matrix

The input is now set to enter the Auto Mixer before going to the Matrix.

Gain Sharing Auto Mixer Inputs

Each input includes:

Mute	-100 to 16 dB, 0.01dB steps.
RMS Meter	-80 to 40 dB, 0.1 dB steps.
Auto Gain Meter	-100 to 0 dB, 0.1 dB steps (Shows calculated gain for each channel).
Manual On	Changes the gain from automatic (off) to fixed (on).Note - While Manual On, the gain for the channel is fixed and does not impact other channels.

Gain Sharing Auto Mixer Outputs

Each output includes:

Gain	-100 to 16 dB, 0.01 dB steps and Mute control.
Priority	Ranges from 1 to 11 (with 1 being the highest and 11 the lowest).An input channel with a higher priority will have a larger gain applied dependent on the Slope value and difference in priority between channels.
Slope	1 to 3, 0.001 steps determine the gain difference between priorities.With a Slope of 1 there is no gain.With a Slope of 2, 2dB for each point of priority difference between channels.A Slope of 3 creates a 4dB gain per point of priority.
Gain Response Time	The amount of time (in milliseconds) it takes to apply a new gain value to a microphone channel.(0.2 to 2000 ms, 0.1 ms steps)

The Auto Mixer is now configured.

FAR AGC (Automatic Gain Control)

FAR AGC keeps the volume at a set level. When the input is below a threshold, it amplifies to bring the level up to the Target Output Level. When the input above threshold, it reduces the gain to bring it back below the Target output Level.

Figure 63: FAR AGC Settings window

FAR AGC Parameters

Target Output Level	-40 to 0dB Detection Threshold (-80 to -20 dB) is the point at which the AGC begins to raise the gain of the signal.
Response Time	1ms to 40,000ms is the period of time before the AGC begins to act when the level is over or under the Target output Level.
Recover Time	1ms to 100,000ms is the amount of time after the Target Output level is below the set level before the AGC begins to increase the gain.
Ratio	1:1 to 5:1 is how much the change can increase/decrease the gain between samples.
Contour HPF	(On/Off) allows higher frequencies to pass regardless of the level.
Noise Threshold	-100 to -40dB is where the noise floor can be set.
Leakage Enable	(On/Off) enables leakage on the ALC so that short-term instances of over/under.
Target Output Level	Target Output Levels are ignored for this amount of time. Leakage Time (100ms to 100,000ms) is how long the leakage is allowed before the gain begins to compensate.

Protocol 3000

Kramer devices can be operated using Kramer Protocol 3000 commands sent via serial or Ethernet ports.

Understanding Protocol 3000

Protocol 3000 commands are a sequence of ASCII letters, structured according to the following.

- Command format:

Prefix	Command Name	Constant (Space)	Parameter(s)	Suffix
#	Command		Parameter

- Feedback format:

Prefix	Device ID	Constant	Command Name	Parameter(s)	Suffix
~	nn	@	Command	Parameter

• Command parameters – Multiple parameters must be separated by a comma (,). In addition, multiple parameters can be grouped as a single parameter using brackets ([ and ]).
• Command chain separator character – Multiple commands can be chained in the same string. Each command is delimited by a pipe character (|).
• Parameters attributes – Parameters may contain multiple attributes. Attributes are indicated with pointy brackets (<...>) and must be separated by a period (.).

The command framing varies according to how you interface with the VS-88UT. The following figure displays how the # command is framed using terminal communication software (such as Hercules):
