2 Operation
2.1 Protecting Your Speakers
It's wise to avoid clipping the amplifier signal. Not only does clipping sound bad, it can damage high-frequency
drivers. To prevent clipping, use software to enable the peak voltage limiter in your amplifier built-in DSP. That
way, no matter how strong a signal your mixer produces, the amplifier will not clip. Set the limiter threshold so
that mixer signals above 0 dB or 0 VU on the mixer meters do not quite drive the amplifier into clipping.
Also, avoid sending strong subsonic signals to the amplifier. High-level, low-frequency signals from breath pops
or dropped microphones can blow out drivers. To prevent subsonic signals, use one of these methods:
□ Insert a high pass filter between mixer output and amplifier input (or between mixer and limiter).
□ Switch in high pass filters at your mixer. Set the filter to as high a fre-quency as possible that does not affect
your program. For example, try 35 Hz for music and 75 Hz for speech. On each mixer input channel, set the filter
frequency just below the lowest fundamental frequency of that channel's instrument.
2.2 Startup Procedure
Use the following procedure when first turning on your amplifier:
1. Turn down the level of your audio source.
2. Turn on the Power switch. The LCD Control Screen should light up.
3. Turn down the amplifier Encoder knobs (Level controls).
4. Turn up the level of your audio source to an optimum level.
5. Turn up the amplifier Encoder knobs (Level controls) until the desired loudness or power level is achieved.
6. Turn down the level of your audio source to its normal range.
If you ever need to make any wiring or installation changes, don`t forget to disconnect the power cord.
For help with determining your system`s optimum gain structure (sig-nal levels) please refer to the user`s manual
Application Guide.
2.3 Precautions
Your amplifier is protected from internal and external faults, but you should still take the following precautions for
optimum performance and safety:
1.Before use, your amplifier first must be configured for proper operation, including input and output wiring
hookup. Improper wiring can result in serious operating difficulties. For information on wiring and configuration,
please consult the Setup section of this manual or, for advanced setup techniques, consult Crown`s Amplifier
Application Guide available online at
2.Use care when making connections, selecting signal sources and controlling the output level. The load you
save may be your own!
3.Do not short the ground lead of an output cable to the input signal ground. This may form a ground loop and
cause oscillations.
5. Setup output channed EQ parameter
6. Setup route of each channel and delay, HPF, LPF, Limit parameter.

4.WARNING: Never connect the output to a power supply, battery or power main. Electrical shock may
result.
5.Tampering with the circuitry, or making unauthorized circuit changes may be hazardous and invalidates all
agency listings.
6.Do not operate the amplifier with the red Clip LEDs constantly flashing.
7.Do not overdrive the mixer, which will cause clipped signal to be sent to the amplifier. Such signals will be
reproduced with extreme accuracy, and loudspeaker damage may result.
8.Do not operate the amplifier with less than the rated load impedance. Due to the amplifier output protection,
such a configuration may result in premature clipping and speaker damage.
9. CAUTION - SHOCK HAZARD: Potentially lethal voltages exist at the output connectors when the amplifier is
turned on and is passing a signal.
Remember: We is not liable for damage that results from overdriving other system components.

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.
software
software software
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.
