8. Advanced Configuration

In addition to the installation of DALI functional profiles described in Section 0.3 of this manual, the DALI-PHANTOM OIAMP-2500 DBP can be further configured to meet a variety of more advanced installation requirements. The advanced configuration options are described in the following paragraphs.

Adjustment of AMP-2500 DSP advanced configuration parameters demands specialist knowledge and should only be carried-out by appropriately qualified audio technicians.

Begin by connecting the AMP-2500 DSP to a network sealed device such as a smart phone, tablet or computer. Open a web browser on the connected device and browse to the DALI PHANTOM OF AMP CONFIGURATOR web interface. The AMP CONFIGURATOR Dashboard, illustrated in Diagram 8A, will be displayed.

NOTE

AVP-2000 DSP network connection is described in Section b.2 of this manual.

The [Dashboard] displays the amplifier status, output zones and the configuration menu tabs. It also enables immediate access to volume control. The advanced functions available under each configuration menu tab are described in the following paragraphs:

8.1 AMP CONFIGURATOR [Input] Tab

The [Input] Tab provides naming, mono/stereo selection, sensitivity, and gain trim for each amplifier input channel. An internal pink noise source, provided for system testing and set up, can also enable or disabled, and adjusted for gain via the [Input] Tab. Diagram 8B illustrates the [Input] Tab.

NOTE

When adjusting input gain, the input level display should remain green. If it displays red, the input gain should be reduced.

NOTE

Compression can be useful to reduce the volume difference between loud and quiet audio materials. The lower the compression threshold is set, the more the difference between loud and soft will be reduced. The overall zone volume may need to be increased when compression is used. The default compression parameters are appropriate for most installations.

NOTES

The number of individual outputs available for configuration will depend on the AYP-2500 DSP input, zone and output mode configuration.

Routing for zones specified as stereo will automatically offer three output options: [Left], [Right] or [Sum] (summed mono). The summed mono signal can potentially be used to power a mono subwoofer from a stereo source.

AMP 2500 DSP Speaker Proseta and distinct from Functional Profiles in that they don't include amplifier input, zone or signal routing parameters.

The [SELECT PRESET FROM LIBRARY, option will be unavailable if no speaker preset libraries have been created. Speaker preset library creation and management is described in Section 7.5.

If an imported Speaker Preset data file includes locked parameters, they will be unavailable for modification.

The AMP 2500 DGP is by default installed with the correct preset for the SUB 5-100 subwoofer. If another preset or a custom preset is desired, clear the current preset and import or create your own.

Diagram 8H
AMP CONFIGURATOR [EQ] parameters

• The [Crossover & Gain] preset menu enables high or low-pass crossover filters and gain adjustment to be applied to individual amplifier outputs.
• The [Speaker EQ] preset menu enables parametric equalization to be applied to individual amplifier outputs.
• The [FIR] preset menu amplia FIR (Finite Impulse Response) based equalization filter coefficients generated by external speaker measurement software to be imported and applied to individual amplifier outputs.
• The [Driver Alignment] preset menu enables delay to be applied to individual amplifier outputs.
• The [Polarity] project manu enables the polarity of individual amplifier outputs to be reversed.
• The [Limiter] preset menu enables signal limiting to be applied to individual amplifier outputs. Clip limiting, peak limiting and RMS limiting can be individually or collectively engaged. The Peak limiter can be set to either automatic or custom parameter values. The RMS limiter has default parameter values that can be adjusted but has no automatic option.
• The [Output Mode] preset menu enables individual amplifier outputs to be switched off or configured for Lo-Z, Hi-Z or Lo-Z DTL modes. In Hi-Z modes, a high-pass filter can also be configured and applied to the output. The number of outputs available will depend on the input setup and zone setup. For example, a two output amplifier will have two outputs available if Lo-Z mode is selected but only one output available if Hi-Z mode is selected.

NOTES

FIR coefficient files in either .csv or .txt format can be imported.

In automatic mode, the back limiter parameters adjust automatically in response to Crossover & Gain high-pass filter settings.

In Lo-Z BTL (bridge-tied load) mode, two amplifier output channels are combined to create a single, double power output channel.

Use of a high pass filter with Hi Z mode loudspeakers is useful to avoid the possibility of distortion caused by low frequency line transformer saturation. Begin with the default filter setting of 70Hz. If low frequency distortion is still audible, increase the frequency setting one step at a time until the distortion is no longer audible.

8.5 [Settings] Tab

The [Settings] Tab enables miscellaneous amplification settings to be configured and installation data to be recorded. The [Settings] Tab provides access to further sub-menus. Diagram BI illustrates the [Settings] Tab

• The [System Information] menu provides text fields for the recording of installation data.
• The [Device] menu records amplifier specific information such as the model number and firmware version. A firmware update routine and identifier button can also be found under the [Device] menu.
• The [Backup & Restore] menu enables amplifier functional profiles to be downloaded to an external archive, and enables previously saved configuration files to be uploaded and adopted by the currently connected amplifier. Explained in Section 5.3.1.

• The [Speaker Library] menu enables management of speaker preset libraries. Libraries of speaker preset files (20) can be created, and existing libraries can be imported, edited or fully deleted. Diagram 8J illustrates the creation and management of speaker preset libraries.

• The [Power Management] menu enables various automatic switch-on and standby options to be engaged. The Power Management menu also offers a United Mute function.

• The [GPIO] menu enables configuration of the multi-purpose GPIO interface pins.

8.6 Setup and Signal Routing

Thanks to the DALIPHANTOM CI AMP CONFIGURATOR the AMP-2500 DSP amplifier offers considerable versatility in terms of sources, signal routing, installation zones and output modes. Inputs can be freely assigned to installation zones, and those zones assigned freely to the available amplifier outputs in either 1.6 Z or Hi Z modes.

This versatility enables, for example, different inputs to be routed to different output zones.

The following paragraphs describe and illustrate the recommended procedure for configuring input, zone and output routing. A general signal flow schematic is also illustrated in Diagram 8K.

8.7 Input Setup

Open the configuration Dashboard and select the [Input] Tab. The [Input] Tab is shown in Diagram 8B.

• To edit default input names simply select and type in the Input Name field.
- Define a mono or stereo input by selecting the appropriate option. Defining a stereo input will reduce the total number of discrete inputs available.
- Select an input sensitivity option from the [Senitivity] drop-down menu +14dB, 4dB, +0dB and 'Microphone' options are available. Generally the +14dB or +0dB options are appropriate for 'professional audio' source hardware with balanced outputs, while the 10dB option is more appropriate for 'consumer audio' source hardware with unbalanced outputs. The [Microphone] option provides the significantly greater sensitivity required for microphone.

NOTE

Only dynamic microphones are suitable for connection. Phantom power for condenser microphones is not provided.

- If necessary, adjust the input gain using the slider or up/down icons. Gain adjustment is intended to be used for fine output level adjustment following initial use.

8.8 Zone Setup & Routing

Open the configuration Dashboard and select the [Zone] Tab. The [Zone] Tab is shown in Diagram 8C

• Select the zone to be configured. The number of zones available and their channel format (stereo or mono) will depend on the amplifier input setup and output mode (Lo-Z or Hi-Z). For example, a two output amplifier can have the following zone configurations:
• 1x stercio Le Z zare
• 2 x mono Lo-Z zones
• 1x mono I II-Z zone
• 1x mono Lo-Z BTL zone
• Name zones by typing in the Zone Name field.
• Adjust the zone volume if required by using the slider.
• Define a mono or stereo zone by selecting the appropriate option. Defining a stereo zone will reduce the total number of further zones available.
• Specify an input for the zone by selecting from the drop-down menu. Selecting a stereo input for a mono zone will automatically sum the stereo channels to mono.

NOTES

When configured in Lo-Z DTL mode or Hi-Z mode, the AMF-2500 DSP amplifier operates in 'bridged' mode where the output of two channels is combined. This means that the number of output channels available in these modes is half that available in Lo-Z mode.

Mono signals might be mono at source, created though combining the left and right channels of a stereo signal (summed mono) or treating the left and right channels of a stereo signal independently (split mono).

8.9 GPIO Setup and Connection

The AMP-2500 DSP amplifier provides a GPIO socket that enables remote control of volume, standby, mute and trigger functions. The GPIO connector pin functions are described in the [GPIO] Settings menu illustrated in Diagram BL. The connection of GPIO based remote volume control and standby/mute are illustrated in Diagram 8M and Diagram 8N respectively.

NOTES

The GPIO connector must not be used for any unintended purpose. Amplifier damage may result from incorrect use of GPIO.
Shielded cable must be used when connecting standby switches and potentiometers via GPIO.
GPIO Pin 9 has a low output impedance and is able to supply a maximum current of 10mA.
GRID Pin 1 and Pin 3 both offer ground connections. Pin 1 is connected directly to the amplifier chassis. Pin 3 is connected to the chassis via a 220 Ohm resistor. The "soft ground" connection of Pin 3 is potentially useful for managing ground loops that may cause audible hum.
