There are three common causes for noise, including static, for the ProMedia 4.1, as well as some less-common causes. 1) A failing 50k potentiometer will cause noise, which will be noticeably affected by adjusting volume. This is common for both the main (4-gang) 50k potentiometer, as well as...

If anyone does decide to move on from their ProMedia 5.1, please let me know. There continues to be interest in the systems, since the consumer market the past decade has gone away from the power, clarity and compactness that Klipsch combined in the ProMedia 5.1. I can likely find a new owner...

Hi, I can help you with your ProMedia 5.1. I just have a busy day ahead, and may not be able to give any detailed answers until later in the weekend.

Hi, This is Henry, stpeteshepherd on ebay. You may reach me at [email protected]. I have an older email address cited a couple of places on this forum, and I did not want to post my new gmail address in the chat, to confuse people who still reach me via juno.

Just to clarify: you have shared pictures of a 4.1 ProMedia (with purple and green input plugs), but are referring also to the 2.1 and 5.1. All three of these ProMedias are quite different, and the 2.1 itself has gone through more than three significant redesigns. It can be confusing. The 5.1...

Hi, The discoloration under the 2N5551 transistor, 22v zener and two resistors is normal. The heat has caused the transistor and zener diode to become heat-sensitive & intermittent eventually on quite a few of these, but still less than 10% of repairs I see. The 680 ohm and 5110 ohm resistors...

Hi, I've repaired the hiss on hundreds of ProMedia 5.1 amplifiers, and once properly repaired and upgraded, it can be solved. The noise could be from a number of places in the AC-DC converter board, or even (not the most likely) the BASH HC1011 board that you replaced on the digital converter...

I would not replace cables that are still working fine. However, if you ever do have issues with noise or loss of one or more channels, the first place to look would be the input cables. A bad cable, especially if it is intermittent, can cause many headaches trying to track down the source. The...

The Klipsch individual amplifier boards fail only very rarely (about one in 500 repairs), and then it is a single board that fails, not a pair. The input cables fail so frequently that I won't reuse them, and the static you describe is consistent with a failing cable or oxidized...

Hi, I may have done your repair. (Your ID here does not show up in my file, but I may have you stored under your given name). The 3.5 mm cables are responsible for about three out of every four ProMedia 5.1 loss of channel issues such as you describe. About one in five is due to a sound card...

Hi, The bulging capacitor should definitely be replaced. I recommend using Panasonic FR replacements. If you had a 4.1 (with the push button switch), I would look for charred adhesive on the bottoms side of the circuit board inside the control pod/preamplifier, which can cause white noise...

Monoprice has 22 AWG cable that length, 3.5mm to 3.5mm for under $8, part number 5582. I've used these cables in 10 ft length with very good results. Monoprice 35ft Premium 3.5mm Stereo Male to 3.5mm Stereo Male 22AWG Cable (Gold Plated) - Black Product # 5582

Hi Nigel, The satellite speakers are 6 ohm, so they can be used with most AV receivers. Typical home speaker impedance is 8 ohms, but good quality receivers can handle down to 4 ohms. They are are efficient and produce good volume per watt, but are not rated for big power. You mentioned the...

If you decide to get rid of the circuit boards for the ProMedia 5.1, I would be interested in them, as well as the control box/pod for that system. I could provide a Fed Ex Ground label, too, if you are in the lower 48 states. There is some core value, and it keeps them out of a shredder or...

When individual satellite channels fail, over 98% of the time the problem is not inside the Klipsch amplifier. (I can only recall about 3 individual amplifier failures in 1000 repairs). First rule out the input cables. The factory input cables were not designed to last 20 years. Frequently they...

The ProMedia 5.1 amplifier for the subwoofer section is rated for 170 watts. Each 8" sub speaker is rated 6 ohms and 100 watts, so 200 watts combined as a pair. In the subwoofer they are wired in series, so have an effective 12 ohm impedance. If they are rewired in parallel that would be a 3 ohm...

Yes, I can help you. There is also Horst in Ohio.

Hi, It has been some years since I posted. I am still doing ProMedia repairs (begun in October 2005). 2020 saw three big improvements: a) an engineer (initials JH; not sure if he wants privacy) helped me develop replacements for the ceramic BASH HC1011 boards that become intermittent. About 1/3...

A few months ago you asked if someone repairs ProMedia 2.1 systems. I do, both the earlier version with the power switch, and the later version without a switch. The earlier version is preferred by many owners.

There are a few typical causes for the satellite speakers to not work--from as simple as a failing 2N5551 transistor or 22v zener diode, to replacing a ceramic BASH HC1011 module (sometimes it will make noise or be intermittent). I am still brand new to this forum, so I am not yet familiar with...

Just a courtesy heads up: I am still repairing Klipsch's ProMedia 5.1. This thread has not been very active recently, so I get emails asking if I am available. As others have noted in past years on this thread, my contact email with juno is correct. Not sure if I may post my own email address...
