4.3 Presets

4.3.1 Introduction

Your I-Tech HD amplifi er has a wide variety of onboard Digital Signal Processing (DSP). Some applications for this DSP are speaker confi guration (setting the drive levels, frequency bands, delays and limiting for your particular speakers), EQ, fi ltering, compression, and much more. Those functions are described in Section 4.6. System Architect software lets you adjust the DSP settings, such as fi lter slope, compression ratio, EQ frequency bands, and so on.

A preset is a group of DSP settings that confi gure the amp for a specifi c application. For example, you might use one preset that optimizes the amp’s DSP for a JBL Vertec 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 50 presets with the LCD Control Screen.

Preset 1 is the factory default preset and cannot be overwritten. It sets up the amplifi er for stereo operation with no DSP.

The I-Tech HD amplifi er works with two types of presets:

1.User presets. Using System Architect, you can create your own custom DSP presets, label them, and send them to the I-Tech HD amplifi er. The amp stores those presets in fi rmware. You can recall those presets from the LCD Control Screen.

2.Downloadable presets. Crown and JBL engineers have designed presets that are optimized for various JBL loudspeakers, such as Vertec Line Arrays. You can download presets from the I-Tech pages in the Crown website www.crownaudio.com. Then in the software, or with a USB drive, send the preset fi les to the I-Tech HD amplifi er, where you can recall them from the LCD Control Screen.

We will describe each type of preset in detail.

4.3.2 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 System Architect 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 I-Tech HD amplifi er. See the software Help fi le for details. As soon as you save the setting as a preset, it is sent to the amplifi er. Another option, described on the next page, is to transfer the preset fi le using a USB drive.

4.Select that preset from the LCD Control Screen. The preset will automatically set the DSP parameters as you set them up in the control software.

Setting some parameters of the DSP in the I-Tech HD amplifi er is done using the control software, not by the amplifi er’s LCD Control Screen. For example, if you want to set fi lter Q, compression ratio, or graphic EQ, you would do so within the System Architect software.

5.When you want to recall the preset, select it from the Preset screen in the LCD display. The preset will automatically set the DSP parameters as you set them up in the control software.

4.3.3 Downloadable Presets

Crown and JBL engineers have designed I-Tech HD DSP presets that are optimized for various JBL loudspeakers, such as Vertec Line Arrays. To use them, follow this procedure in System Architect:

1.Go to the I-Tech pages at www.crownaudio.com.

2.Select Downloads.

3.Click on the fi le of your choice. It will download to your computer.

4.In System Architect, see the Help fi le on Presets for details on downloading the preset to an I-Tech HD amplifi er. Basically, you will open and engage a data frame. The fi le will overwrite the preset you designate. Another option, described on the next page, is to transfer the preset fi le using a USB drive.

5.Recall the preset from the LCD Control Screen. Then your amp will be

confi gured to work with the specifi ed loudspeaker model.

Section 4.8.19 describes the Presets Manager screen in System Architect.
