When I turn-off the amplifier there is also a POP on the speakers and one can see the speakers stay in a inflated or deflated position for a short while. When I tried to turn up the gain of the mono output I heard some crackling, then one of the speakers connected to one of the 4 primary channels inflated or deflated (probably DC voltage on speaker outputs ?), not sure whether it inflated or deflated as I hastily turned back down the gain before the speaker overheated. The mono-output was even weaker than the rest of the channels and it was noisy. Can be bridged all the way down to a 1/2 ohm. Has built in crossovers for a clean and hassle free installation. Then I fired it up with speakers connected and I noticed the analogue amperage indicator of out power supply went over 3 ampere for a fraction of a second, during which their was a loud POP out of the speakers before it idled nicely.Īll 5 channels produce sound, though very low, much lower than I have ever heard even out of the less powerful models such as 200s and 405s. Reference 405 by Soundstream this is what the guy sent me Capable of powering your entire system with an underrated 50 X 4 + 200 X 1 2ohms. We put the amp back together to see what happens and when I hooked it up (without any speakers) it idled nicely at about 1.5 ampere.

The solderings were pretty good, but I must say I often find them to be better on these s /sx amps than on the original Reference amps (mainly driver board solderings), though the s / sx have other issues.

We did an ohms test with the DMM on the rectifier diodes which are problematic on Reference amps but they did not appear to be shorted on this amp. We removed the board, refreshed some solderings and sprayed some contact cleaner on the switches and worked them back and forth many times. The seller told me only two of the five channels were functional. I purchased a malfunctioning 705s for a friend of mine.
