![]() ![]() Now the KA-3500 doesn't have any way of adjusting DC offset without replacing some resistors. To test a more metallic tone, we went for a tight, Mesa-style saturation via the Treadplate model. If you are listening to an amp with 100mV or more of DC offset, you have some serious distortion happening. BIAS Amp 2 is a solid improvement over its predecessor, with stronger, more responsive amp tones. Amp is way out of spec.ġ00mV to ?: High enough voltage will cause the protection circuit to kick in (where is dependent on how it was designed). On the desktop version of BIAS AMP 2, you can find the preset menu located on the panel right next to the ToneCloud icon. Distortion is probably not audible.ĥ0 - 85mV: Not good but not enough to put your speakers or equipment at risk. BIAS AMP 2 organizes its global amp presets into several categories. Die integrierten IRs sind eine echte Erleichterung und das Bluespack macht auf den ersten Blick auch einen guten Eindruck. If you read '0V', you may have a capacitor output, or your meter is set wrongġ6mV - 50mV: Acceptable, especially at the lower end of this range. Having other applications running will eat up the CPU usage as well. ![]() Lower Buffer Size and/or higher Sample Rate setting will also cause higher CPU load. CPU will overload more easily on certain presets with more effects and/or dual amp setting. Connect the multi-meter directly to the +ve and -ve of the speaker terminals on the amp (A or B doesn't matter. The crackling noise is due to insufficient CPU usage. Set multi-meter to read DC volts, at a low scale (say 200mV to 500mV)ħ. Set the source input to something unused (not Phono)ĥ. So yeah, I get it that taking them out of service for restoration and writing a big check isn't a happy thought for most, but it is an investment at this point as a single good and other bad amp just doesn't have the value, but (documented and proper) restored amps do.Start with the DC offset - that one you can do without opening up the amp. BIAS FX 2 Desktop Product Information Amp & Cab Model List. and I now realize that they sound better. In the end, the listening experience is much more relaxing and I can leave the room to use the bathroom without leaving the door open listening for bad sounds. made it worth the time and money to totally restore. ![]() Mine were in exceptional working condition, sounded great, the excitement that they are all original, but since I wanted to actually use them the real risk of losing a power transformer to a runaway bias or losing all of my expensive output tubes. Transform your computer or mobile device into a fully customizable guitar and bass rig with BIAS FX 2 packed with hyper-realistic amps, pedals, HD racks, and more. Tut was es kann und wertet den Gitarrensound beim Homerecording extrem auf. OMNYSS is powered by our award-winning BIAS FX 2 amp & effects software platform, and comes with BIAS FX 2 LE. Dazu ist es im Vergleich zu anderen PlugIns mit ähnlicher Ausrichtung deutlich preisgünstiger. and when it does it might cause other damage. Das Positive Grid BIAS Amp 2 Plugin bildet eine Vielzahl an klassischen Amps sehr detailgetreu nach. Every time they're turned on, every time you leave their sight, there is a risk that something is just about to fail. Égaliseur graphique, préamplis Glassy, Crunch et Insane et Poweramps sans compter de nombreux baffles. 36 modèles damplis HD et blocs dextension blues et basses inclus. Please report back on this exercise before asking again, without this information we're guessing here.Īlthough it would be nice to continue turning them on and listening blissflully to the music that spills forth knowing that the components and design were first-rate in its time. Logiciel de modélisation dampli polyvalent avec de nombreuses capacités dédition. If you swap tubes between the amplifiers and the noise does not come back, I'd suspect a bias issue (resistors). If it stays with the same amp after changing all of these things, it is likely a capacitor (but can be a resistor) and doesn't the MC30 have one selenium rectifier? You can move all of the large tubes, then small, and eliminate the tubes that way. I don't see any response as to whether you have tried the above: turning the gain down, swapping tubes between the amplifiers, swapping speakers and inputs between the amplifiers.įirst try turning the gain up/down, if it changes with the gain then swap the input cables left/right, if not then swap speaker cables left/right, if it still doesn't change swap tubes left/right.Trade each item one at a time until you find which (if any) moves the noise to the other channel. It should be the same in all three points. Check your bias voltage on pin 5 of both E元4s, then check it where the 220K grid leak resistors meet. I guess we can rule out a noisy transistor.
