Perry is correct about the resistors opening up and sometimes they are even nice enough to show you by changing color. Just tech out the little transistors used by the protection circuit also, they might have been fried along the way to your bench Strength: The sub channel very super powerful at 1ohlm my hcca a orion Oldskool dual 2ohlm is rocking tremendously load hits so hard just waiting for ny ears to start bleeding. At first glance, you’ll notice several key improvements Rubicon Nano’s signal inputs, power/ground, and speaker connections are all relocated to the. Specifications: Class D Rubicon Mono Channel Amplifier. The FEBs are fairly cheap to buy save the time and dump it for a new one, Jaime ships fast out of Nor-Cal where we live. Model Reviewed: Soundstream Rubicon 550-5. We’ve adopted the most optimum Class D performance, reliability, and smaller footprint platform for the Rubicon series amplifiers and present to you Rubicon Nano. Rubicon brings the famous Soundstream quality into a no-nonsense, yet fully loaded, timeless amplifiers. Removal of the defective devices should release the rest of the circuits from being light up. I am the engineer that designed and manufactured all of the Old School Soundstream amplifiers and crossovers from 1981 through 1998, all REFERENCE, CLASS A’S and old RUBICON amps. Given this situation then the fault from the bad channel is causing the other symptoms. SOUNDSTREAM OLD SCHOOL AMPLIFIERS Hello, my name is Wade Stewart. Since only one channel is blown I am figuring logically that the rest are OK. the FEB it sends the signal to that clip LED and they are all interconnected so I am thinking if you remove the bad FEB board and the driver transistor located nearby the rest of the LEDs should be extinguished Try this to check my thinking. The 0.33 resistors are critical to the proper operation of this circuit.Īs for the clip LEDs please see the driver board i.e. This is your DC offset/ over current protection circuitry. Headphones are optimally suited for analyzing tonal artifacts in a recording but completely distort distance perception.If you have the schematic then look at the emitter resistors that you need to change they are current sense lines going to a MPSA-92 transistor on the output of each channel. "Headphones are completely unsuited for judging the spatial rendering of a stereo recording that is intended for loudspeaker playback. Headphones are optimally suited for analyzing tonal artifacts in a recording but completely distort distance perception." -LINKWITZ Amplifiers Soundstream Rubicon 2500.1 Soundstream Rubicon 2500.1.

"It's enormously important to understand that there is absolutely no possibility of having any pleasure in life at all without skill. Soundstream RN5.2000D Rubicon Nano 2000W Class D 5-Channel Amplifier. Unfortunately very few of our current genre of acoustic tests have had this kind of introspection." - Geddes It is the perceived sound quality that matters not the measured quality – unless that measurement has been scaled and correlated to subjective perception through valid psychoacoustic tests. "Blind reliance on measurements can be misleading ‐ one needs to tie those measurements back to subjective perception. The room response gives a picture of the steady state SPL, where sound generation and sound dissipation in the room have reached their equilibrium." -Linkwitz The resulting curves must not be taken as a 1:1 representation of what is heard as loudness at different frequencies. " The room response must be averaged to recognize trends in the summation of direct and reflected signals at the microphone.
