9. LCD Control Screen
Integrated LCD with blue back light, controls amplifier setup and operation.
The LCD Control Screen and its controls let the user adjust the amplifier's attenuation and muting, configure the
amp, set up and view error monitoring (such as temperature and load supervision), and recall DSP presets. The
presets allow the user to quickly reconfigure the amp for various applications.

14. Balanced Analog XLR Loop-Through Outputs
Two 3-pin male XLR output connectors are pro-vided (one per channel). The signal at these connectors is
paralled with the input signal for feeding the input signal to other amplifiers.
15. RS485 In-Out
Rj45 sockets. Used for transmission of remote control data over long distance or multiple unit applications.
16. Speakon Output Connectors
Class 1 output wiring required.
These two connectors accept 2-pole or 4-pole Speakon connectors. The output1 Speakon connector is wired for
both channels so it can be used for bridge-mono wiring or for stereo wiring of two speak-ers to a single Speakon
connector.

Protect LED
Each channel has a Protect LED that will light when the load connected is lower than 1 Ohm or amplifier broken.
11.Clip/Limiter LED
Each channel has a LED that light at the real clipping point (more than 0.5% T.H.D.) and also indicates the input
signed is compressed by amplifiers.
12.Signal bar LED
Each channel has a bar LED, as the input signal strength increase, the green SIGNAL -30dB, -24dB, -18dB, -
12dB, -9dB, -6dB, -3dB, 0dB LED indicators light respectively.
13. Balanced Analog XLR Inputs
A 3-pin female XLR connector for each chan-nel.
Standard 15 amp IEC inlet. Voltage range is indicated above IEC inlet.
S.N. Label
Every unit has a label indicating: the model, and the barcode serial number.
Fan exhaust ports
Heated air exits the amplifier through the exhaust ports, located on the rear of the amplifier chassis. Be sure not
to block this ports, especially when rack mounting the amplifier.
3 Advanced Operation
3.1.1 Introduction
A
preset
is a group of DSP settings that configure the amp for a specific application. For example, you might use
one preset that optimizes the amp`s DSP for a Line Array. You might use another preset that sets up the DSP for
a stereo pair of loudspeakers of your choice. You can choose any of ten presets with the LCD Control Screen.
1. Installed presets.
Some presets are already installed in your DPi Series amplifier. You access them with the
LCD Control Screen as described above. When recalled, each preset will automatically set the DSP parameters
for a particular application.
2. User presets.
Using software, you can create your own custom DSP pre-sets, label them, and send them to
the DPi Series amplifier. The amp stores those presets in firmware. You can recall those presets from the LCD
Control Screen.
3.1.2 Installed Presets
To select a preset that came installed in your amplifier:
1. Press the
Menu
button below the LCD Control Screen.
2. Turn right encoder-1 knob to see subprogram.
3. Turn an Encoder knob until you see the preset number you want to recall.
4. Press the Enter button to select that preset number.
The preset will automatically set the DSP parameters for that particular application.
3.1.3 User Presets
User presets are DSP presets that you set up. This is the basic procedure:
1. Adjust the DSP settings as desired in the software (not with the LCD Control Screen).
2. Save this group of settings as preset. Give it a label.
3. Download the preset to the DPi Series amplifier. See the Presets Help file in software for details. Basically, you
will open and engage a data frame.

4. Setting the parameters of the DSP in the DPi Series amplifier is done using the IQwic software, not by the
amplifier LCD Control Screen. For example, if you want to set filter Q, compression ratio, or graphic EQ, you
would do so within the IQwic software.
Adjusting DSP parameters within
can be done in two ways: with a software directly. The Wizard asks a
series of questions to help you set up DSP parameters for loudspeakers.
After setting the DSP parameters as desired:
1. Save them as a preset in
. Presets are stored and recalled through the Presets Page in
.
2. Download the preset to the DPi Series amplifier.
3. When you want to recall the preset, select it on the LCD Control Screen.
