Blackstar Fly 3 PSU Official Power Supply for Fly 3 Mini Portable Amplifier.

Product Information

These speakers have different sounds for all sorts of reasons, but one of the main ones is that the construction and electrical characteristics mean certain frequencies peak or dip. Fly 3 can be powered by batteries or an optional power adapter (regular pedal adapter will not work as it requires 6.

There's a bunch of maths (sorry math if you are in the USA) which speaker designers use to make ports in their cabinets resonate at the frequency they want. FAQ2: I've plugged my guitar/pedals into both the Blackstar Fly3 and into another guitar amp, and I get hum. soft clipping around IC1A and will give much more noticable distortion, as well as reducing the signal voltage into the next stage. Treble and bass roll-off is most likely part of speaker simulation circuit and doesn’t seem to be affected by ISF control.Don't confuse this with audio limiting (although there are a lot of similarities) which limits the envelope of the audio signal (in other words how loud it is).

I thought I'd see a cheap linear power amp chip, a couple of op-amps at most, maybe some clipping diodes, and that's about it. Blackstar placed an "RF choke" on the wiring of their supply (it's a round black cylinder) which helps eliminate high frequency hum. You might think a low pass filter is just for audio but in fact they're used all over the place in electronics, and in this case on power supply rails.These get seen at the Amp input -sig and so get amplified (the Amp amplifies the difference between -sig and +sig).

Fly 3, like most of other “warm digital delay” circuits uses PT2399 delay chip that is imperfect to begin with.In any case TR1 must turn on when the +5V rail is up (I mean switched on) and provide a steady current to light the red LED .

Along the bottom from left to right is the frequency in Hertz (a German scientist's name - which fits well with a German made loudspeaker). If your goods develop a fault within the warranty period, we'll quickly repair or replace the item for you.I recently accidentally plugged a 300ma 12v adapter into my fly 3 bass and now it no longer powers on with batteries or adapter, no LED, no sound. Instead, I've found a consumer type Class-D power amplifier chip, a sophisticated clipping circuit which is love-child of a Tube Screamer and a DS-1, a separate headphone amp IC, and a whole bunch of carefully designed op-amp based EQ filters. This enhanced warranty is in addition to the standard Gear4music and manufacturer warranty policies, and the Gear4music terms and conditions of trade. The audio shield is maintained because it is still connected to Ground at the source end (where the signal comes from). Smaller caps are there to deal with higher frequency supply currents, and large caps are there to act as a resovoir when there are large current spikes, which evens out bumps in the voltage.
