AFM-20DSP – Introduction

Introduction

Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been providing a world of unique, creative, and affordable solutions to the vast range of problems that confront the video, audio, presentation, and broadcasting professional on a daily basis. In recent years, we have redesigned and upgraded most of our line, making the best even better!

Getting Started

We recommend that you:

• Unpack the equipment carefully and save the original box and packaging materials for possible future shipment.

• Review the contents of this user manual.

Go to www.kramerav.com/downloads/AFM-20DSP or

www.kramerav.com/downloads/AFM-20DSP-LE to check for up-to-date user manuals,

application programs, and to check if firmware upgrades are available (where appropriate).

Achieving the Best Performance

• Use only good quality connection cables (we recommend Kramer high-performance, high-resolution cables) to avoid interference, deterioration in signal quality due to poor matching, and elevated noise levels (often associated with low quality cables).

• Do not secure the cables in tight bundles or roll the slack into tight coils.

• Avoid interference from neighboring electrical appliances that may adversely influence

signal quality.

• Position your Kramer AFM-20DSP / AFM-20DSP-LE away from moisture, excessive sunlight and dust.

Safety Instructions

Caution:

• This equipment is to be used only inside a building. It may only be connected to other equipment that is installed inside a building.

• For products with relay terminals and GPI\O ports, please refer to the permitted rating for an external connection, located next to the terminal or in the User Manual.

• There are no operator serviceable parts inside the unit.

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).

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 24: 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 the desired volume level into this box and press Enter on your PC.

Using Expander Module

Use the Expander module to increase the difference in loudness between the quieter and louder sounds, so that the quiet sounds (usually background noises) become quieter while the loud sounds become louder. The levels of audio signals that fall below the set threshold level are reduced.

To adjust the expander module:

1. In the Navigation pane, click DSP. The DSP (Main) page opens.

2. Click Exp. The button turns light blue and the Expander module page appears.

Page 30

Kramer Electronics Ltd.

AFM-20DSP – Processing Audio Signals

3. Click the Off button . The Exp module turns on .

Figure 28: Processing View – Expander Module

4. Define the following:

▪ Threshold – Decreases the volume of audio signals that are below the threshold

level.

▪ Attack Time – Sets the response speed of the expander to signal levels above the

threshold.

▪ Release – Sets the response speed of the expander to signal levels below the

threshold.

5. Open the Ratio drop-down box to set the extent to which the volume is decreased. The higher the ratio the more the audio level below the threshold is lowered.

The Expansion (dB) indicates the amount of expansion in a dB scale.

Expander settings are adjusted.

Using HPF (High Pass Filter) Module

A High Pass Filter passes signals that are higher than a certain cut-off frequency. Frequencies under the cut-off frequency are attenuated. Use the HPF module to cut off low frequencies and let higher frequencies pass.

To adjust the HPF:

1. In the Navigation pane, click DSP. The DSP (Main) page appears.

2. Click HPF. The button turns light orange and the High Pass Filter module page appears. The left side shows the input volume slider.

Page 31

3. Click the Off button . The HPF module turns on .

Figure 29: Processing View – HPF Module

4. Set the cut-off frequency.

5. Select the HPF low-cut algorithm type (or select None):

▪ Bessel – A linear filter with maximum linear phase response. It is often used in audio

crossover systems.

▪ Link R (Linkwitz-Riley) – An Infinite Impulse Response (IIR) filter used in audio

crossovers. Consists of a parallel combination of low-pass and high-pass. The filters are usually designed by cascading two Butterworth filters, each of which has a -3dB gain at the cut-off frequency. The resulting Link-R filter has a -6dB gain at the cut-off frequency.

▪ Butter (Butterworth) – Designed to have a frequency response as flat as possible in

the passband.

6. Select the HPF slope (24, 18, 12 or 6dB/Oct) – set the filter drop-off per octave from the filter frequency.

HPF parameters are adjusted.

begin working. If a signal is too low or does not cross the threshold, the compressor allows the signal to pass through unchanged.

▪ Attack Time – The response speed of the compression to signal levels above the

threshold.

▪ Release – The response speed of the compressor to signal levels above the

threshold.

AFM-20DSP – Protocol 3000

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

<CR>

• 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):

Function

Description

Syntax

Parameters/Attributes

Example

Set protocol permission.

For devices that support security, LOGIN allows the user to run commands with an End User or Administrator permission level. When the permission system is enabled, LOGIN enables running commands with the User or Administrator permission level When set, login must be performed upon each connection

The permission system works only if security is enabled with the “SECUR” command.

It is not mandatory to enable the permission system in order to use the device

In each device, some connections allow logging in to different levels. Some do not work with security at all.

Connection may logout after timeout.

COMMAND
