Problems Overload Protection Being Invoked - Parasound HCA-2003

I have a Parasound HCA-2003 that I recently purchased used. The area of problem appears to be in the overload protection. The amp has been tested to prove it wasn't the amplifiers themselves - they appear to be OK. It's just these overload circuits that appear to be causing the amplifer from properly working.

I've had it in a shop for over 8 weeks now. I'm frustrated with the level of - or, lack thereof, service so I've requested that they return my amp to me.

    I was careful with the connection of the speaker wires. Actually, I used banana plugs for my connections.

You may want to get an Ohm meter and check between the outputs of the amp yourself. 0 ohms means a short somewhere.
You should also check to se when you're hooking the speaker wires in that they're not frayed and touching hot to ground or hot to the amp casing. hope that helps!

What kind of pre amp do i need to operate my parasound HCA-2205A high current power amp


Any preamp should work. A preamp goes into your system between the amp and the other components which plug into it- CD player, FM tuner, Turntable.....etc. It's takes their output signal, processes it as my be Volume, bass, treble... and then send a sufficient signal to the amp to drive the amp to power your speakers. As long as the preamp output is enough for your Amps input any will work as most will be.

How to fix 2 fuses on the left of the amp? the right side work well.


Fuses only blow if there is an overload somewhere. The most likely cause being a transitor that has shorted out. Easy to spot with a multi-meter on the ohms setting. As it will be liked you have touched the test leads together!

I have an overload indicator on channel 2. I opened the lid and swapped the channel 2 module with the channel 5 module and the overload light followed the card and showed up on channel 5. Parasound said...


I believe that the output transistors may be bad. Without seeing the actual card, there is no way to tell. If the parts are under warranty, request a replacement board. If I remember correctly, the board is the field replaceable unit (smallest orderable part) anyway. If not, you will need instruction from Parasound about what to do next.

Smell like a electrical smell ocassionaly coming


Its probably getting hot so you might smell the components heating up. I would try to if possible clear up some space and try cleaning the unit with a air can. Try to get dust that builds up over time

Noisy transformer


Normally, power transformers don't hum loudly unless there is a problem in power supply circuit. If all seems normally operational, the problem may be simply anchor screws that hold transformer to frame may be loose. Try tightening them
