Helix HXA-500 tripping protection mode

Hello I recently developed a problem with my Helix HXA-500 amp. Upon initial power up I get the green LED showing normal status. However about .5 sec after power up it switches to protection mode with a yellow LED. Consulting my owner’s manual a yellow LED indicates “speakers shorted to ground”. But after checking OHM loads to each component every thing seems in order there. So I pulled out in interior of my car looking for breaks in the cabling shields. No breaks were found any where. So I decided to see if the amp would power up with the speaker leads completely disconnected. And I got the same result listed above. (Amp tripping to protection mode) So I decided to check external power lines for high resistances. And I found no resistance problems either. And the supplied voltage to the amp is normal as well. Around 13.5 volts (engine off) (14-15 volts running)

I can only conclude that it’s a problem internally to the amp. This amp has never been abused with vibrations or heat NORE driving low OHM loads.

Here inlays my problem: due to installation issues and space requirements I can not fit another brand/make of amp to replace it. Comparable amps are simply too large to fit into the allotted space. And since Helix/Brax isn’t sold in the USA any more finding a replacement has been very frustrating. Do you know of any companies here in the United States that are competent/capable of repairing my amp?

I should note that I have tried to contact Helix/Brax several times to no avail. In a effort to find a factory approved service facility. I guess they would rather ignore my e-mail/calls rather than translate every thing into german.



Thank you for your time and effort on this matter

    No i havent tryed unhooking the RCA's, however the same RCA's also feed a kenwood amp for the subs. And the kenwood powers up fine and puts out sound as normal. Given that the second amp functions normaly i didnt suspect a problem there. But i will check into it.



    Thank you for you time and effort.

Have you tried unplugging your RCA's? There could also be a fault in the ground on the RCA cables.

    I'm getting in touch with an amplifier repair shop to see if they can help you with your issue. I'll keep you posted.

    Hello again =)

    Hi,
    Repairing the Helix should be no problem. The symptoms seem to indicate a bad channel. Any one of the 5 channels, when damaged, can cause the amp to go into PROTECT and shut the power supply down. When this happens, none of the channels will play.
    This amp uses TO-3 style outputs. We only stock a few of these style outputs, so we might have to order them. They should be readily available. The repair should take about 2 weeks. You get a 90 day parts and labor warranty. We pay return shipping.
    If you would like to send it in for repair, just go to www.amprepaircenter.com and click on "Submit Repair". Once it arrives, we will contact you with an exact diagnosis and cost.
    Thanks,

The Limit Prot LED on my RCF Art-321A speaker remains on upon power up. The speaker also pops upon powering down. What do you think it could be? Thanks


The amp is blown. Some popping on power down is NOT uncommon, but the protect LED means the pwer amp is out of balance which is ******* speakers. Take in for repair.

Welcome to Fixya
If this happened recently then try to reset the printer to factory state. Please see procedure below:
1.Connect the Canon PIXMA iX4000 printer to the power cord. ( note : If the automatic power-on function is enabled in the printer, the printer enters the service mode for the first time, but it will never enter the service mode if the printer is turned off by the Power button. This is because the printer remains to be turned on internally if the power is turned off by the Power button. To prevent this, disconnection of the power cord is required before starting the printer in the service mode ) .

2.With the Canon PIXMA iX4000 printer powered off, while pressing the Resume/Cancel button, press and hold the Power button. (note : Don't release the buttons. The Power LED lights in green to indicate that a function is selectable.)

3.While holding the Power button, release Resume/Cancel button. (Don't release the Power button.)

4.While holding the Power button, press Resume/Cancel button 2 times, and then release both the Power and Resume/Cancel buttons.

5.When the Power LED lights in green, press the Resume/Cancel button 4 times to reset waste ink counter in the Canon Pixma iX4000. (note : If the Power LED does not light in green the printer does not enter the service mode, disconnect the power cord and plug it again. Then start from step 1 to start the printer in the service mode again).

6.At the end of the service mode, press the Power button. The paper lifting plate of the sheet feed unit will be raised.
Note :

Each time the Resume/Cancel button is pressed, the Alarm and Power LEDs light alternately, Alarm in orange and Power in green, starting with Alarm LED.
Other specified number of time(s) according to the function listed in the table below.

Time(s) LED indication Function Remarks
0 times Green (Power) Power off
1 time Orange (Alarm) Service test print
2 times Green (Power) EEPROM information print
3 times Orange (Alarm) EEPROM initialization
4 times Green (Power) Waste ink counter resetting
5 times Orange (Alarm) Destination settings
6 times Green (Power) Print head deep cleaning (Cleaning of both black and color)

Thank you for using Fixya!

Power led flashes and amp doesnt work at all


Hello hexi_86, The amp is going into protection mode. If it goes into protection immediately upon power up, either the amp itself is defective or it is getting too high or too low of a voltage or current, or the outputs are shorted. 1) Make sure that the battery voltage, as measured at the amplifier?s +12 volt and ground terminals, is 11 volts or more (your alternator voltage is typically about 13.8 volts). So if you have 11 or less at the amp terminals, your wiring is too small or defective. 2) Check all +12 volt and ground connections. 3) The use of loudspeaker impedances below the recommended minimums will cause the amp to draw excessive current. Check by removing the speaker wires one at a time to locate a shorted wire or defective speaker. 4) Check all speaker connections. 5) Remove RCA inputs and see if the amp powers up properly. A shorted or grounded RCA cable can cause the amp to go into protection. If all these check out, the amp itself is probably shorted internally, most likely the output MOSFET's. In this case it needs professional repair or replacement. Hope this helps.

If the amp goes into protect mode, it's likely due to shorted output transistors. To eliminate other possible problems, read through the following page:

If the problems are not with the wiring, follow the link at the bottom of the page to the Amplifier Repair Primer page.

Green LED comes on then fades out


This is common when the output transistors have failed. The amp powers up and the amp senses a problem and goes into protection mode. Generally, there is a protection LED but not all amps have them. To be sure that the problem is not installation related, check the DC voltage across B+ and ground when the amp tries to power up. If the voltage remains above 11 volts, the problem is almost certainly due to a failed component in the amplifier. Disconnect the signal lines and all speakers (disconnect the wires from the amp terminals) and try to power it up. If it powers up, you could have a defective speaker or defective wiring. If the amp still fails to power up, the amp should be checked by a qualified tech.

Power on problem


Time for a little repair here. It seems that one or more channels have developed an excessive drain on the supply, and has caused the threshold to trip and shut you down. It's more than likely shop time at this point....accordianman
