In automatic mode, the peak limiter parameters adjust automatically in response to Crossover & Gain high-pass filter seings. 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 possibili of distortion caused by low frequency line transformer saturation. Begin with the default filter seing of 70Hz. If low frequency distortion is still audible, increase the frequency seing one step at a time until the distortion is no longer audible. 26 27Diagram 8K Amplifier Signal Flow Schematic Analog 3OutputMatrixZones A - BOutputs 1 - 2 Analog 2InputSensitiviAnalog 1Input Gain InputSensitiviInput Gain InputSensitiviInput Gain Analog 4SPDIF (stereo) SPDIF Out (stereo).Zones A (le) and B (right) Pink Noise Gain LevelAdjustment LevelAdjustment CompressorCompressorDelayDelay

8.6 Setup and Signal Routing

Thanks to the DALI PHANTOM CI AMP CONFIGURATOR the AMP-2500 DSP amplifier oers considerable versatili 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 Lo-Z or Hi-Z modes. This versatili enables, for example, dierent inputs to be routed to dierent 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.

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

• Select an input sensitivi option from the [Sensitivi] drop-down menu: +14dB, +4dB, -10dB and “[Microphone]” options are available. Generally, the +14dB or +4dB 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 sensitivi required for microphones. 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:

• Name zones by ping 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.

• Speci 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 BTL mode or Hi-Z mode, the AMP-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 le and right channels of a stereo signal (summed mono) or treating the le and right channels of a stereo signal independently (split mono). 28 298.9 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] Seings menu illustrated in Diagram 8L. 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 8 has a low output impedance and is able to supply a maximum current of 10mA. GPIO Pin 1 and Pin 3 both oer ground connections: Pin 1 is connected directly to the amplifier chassis. Pin 3 is connected to the chassis via a 220 Ohm resistor. The “so ground” connection of Pin 3 is potentially useful for managing ground loops that may cause audible hum.
