If the microcontroller (U1, LPC2142) has NEVER been programmed before Connect the Serial 4-pin header to J2. IMPORTANT!! The header MUST be connected with the correct polarity or fatal damage can result.

To reprogram a device, it is first necessary to put it in bootloader mode. This is done by shorting TP17 to ground during a power up. After the unit powers up, the ground can be removed or left connected, doesn’t matter.

Open up the CLoader Utility 2.10 or newer If fw is older than 1.0.22.0 send .hex file. Otherwise, send .s file How to Use the CLoader Utility Instructions: Simply run this utility with an amplifier connected to USB, it should show up in the dialog window.

It can also usually be found in the forums section of the Crown web site (www.crownaudio.com) -The next place to look would be my share drive. I usually keep beta firmware and different versions of the CLoader Utility there.

(Program) 2. 2M-bits (256 kBytes) of serial flash U15. (Program and Data Memory) When firmware is loaded via RS-232, it uses a very low level bootloader on the microcontroller and only the on-chip flash is reprogrammed.

The DSP/uP has no other information about output signal of the amplifier. Given the latency of the amplifier and conversion stages, the fastest the output signals can be limited is about 15ms.

It is based on the number of clip events. If the clip eliminator routine has counted 243 clip events and run the limiter all the way down to -24dB, it continues to count clip events.

The temperature compensated servo transistor Q109 is located under the same heat sink ( + ) and near the LM75. The bias set string with D174, R180, R144 and R179 run about 400ua and are not under that heat sink. With the pot R144 centered an bias on the collector to emitter voltage of Q109 measured across C109 should land about 1.9 to 2 volts.

R130, R132 (main feedback) and C104 form the voltage feedback and high pass function for the power stage. D3 is a clamp function. Using standard long stepped bursts of waveforms will result a normal high pass step recovery of the at the amplifier output, which may initially look abnormal to other high passed amplifiers.

Energy is also transferred back to C196 through D26. If the voltage at C196 is maintained at a point greater then the lower bound for the Vkstart sense comparator, U16B, then the controller circuitry becomes sustained by the converter itself and the kick start cycle is terminated.

The demands and feedback signal both feed a virtual ground at the inverting input. Both local feedback around the error amplifier and global feedback from the amplifier rail are employed. A single diode (D73) provides an asymmetric voltage clamp that properly bounds the error amplifier.

None Crown XTi Changes: 1. Changed the sequence of events at power up. After initialization the DSP output is muted for a longer period of time to guarantee the amplifier has enough time to bias up before getting signal.
  • Page 157 找资料学技术，故障求助 请到http://bbs.bjjdwx.com 海量维修资料免费下载 Crown XTi Known Issues: 1. Amplifiers built before September 2006 must use the CLoader utility and .hex file to update firmware. See detailed instructions at: http://www.crownaudio.com/amp_htm/cdi-dsi-xti-firmware-update.htm 2. Older versions of firmware (prior to 1.1.2.9) sent the full serial number to the Windows HID driver. If this driver receives any zeros in the serial number, it will not allow more than one USB amplifier online at a time and will in fact crash very hard when this occurs.
  • Page 158 找资料学技术，故障求助 请到http://bbs.bjjdwx.com 海量维修资料免费下载 About the CLoader Utility: When you download System Architect from the web, or get it from a CD, the CLoader Utility will be included. The CLoader is a very small and simple program that is used to load new firmware into a USB enabled amplifier.
