PC-2A Supplemental

PC-2A Supplemental

The front panel of the PC-2A compressor has been intentionally designed to be minimal. This is so that musicians can focus on playing without the uneccessary distraction of too many knobs and buttons. However, although the front panel layout is simple, the PC-2A is no one trick pony. Within this little pedal there’s a full-featured pro-audio grade side-chain which controls the photo-optical attenuator. It’s a killer combo as you get the low distortion, fast attack and slow release inherent in a photocell coupled with the wide dynamic range and purity of a vacuum tube signal path, and the control of a side chain.

PC-2A internal ‘knee’ and ‘attack’ trimpots (note the silver plated circuit board!).

The PC-2A side-chain allows some additional control of the photocell to slow it’s attack time and extend it’s release time by a set amount. The attack time can be slowed using the internal ‘Attack’ trimpot to further reduce ‘pumping’ artifacts until they are inaudible. Rotate the ‘Attack’ trimpot anti-clockwise for ‘fast’ attack and clockwise for ‘slow’ attack. This is very useful with acoustic guitars fitted with piezo pickups, giving them a fuller more rounded tone.

There’s also an internal ‘Knee’ trimpot which smooths the PC-2A’s transition into compression to further improve transparency. Rotating the ‘Knee’ trimpot anti-clockwise gives a ‘hard’ knee transition into compression like a limiter and clockwise for a ‘soft’ knee and more gradual transition into compression. With the ‘Knee’ trimpot fully clockwise and a slow attack the PC-2A is incredibly transparent, in fact you won’t be able to hear it compressing at all, but you will hear it working as a tone enhancer. It works fabulously on ‘difficult’ instruments such as 5-string active bass, that is, instruments with wide dynamic range, fast transients and wide frequency response – situations where a transistorised or opamp based compressor would not be able handle the signal without loss of clarity, definition and coherence.

These two audio tools do essentially the same job These two audio tools do essentially the same job—compress (level out the dynamics) your guitar signal using class-A vacuum tube electronics and photocells. However, the Leveling Amplifier has a few extra bells and whistles up it's sleeves. It was primarily designed following requests from sound engineers and musicians for a four knob version of our PC-2A photo-optical tube compressor to include 'attack' and 'knee' knobs. We took this on board but, being engineers, we also added several other really cool features including balanced transformer isolated output, gain pad, tube boost, dynamic equaliser and parallel tube input stage (4 triode tube gain stages in parallel) for hyper-quiet operation.#effectrode #PC-2A #compressor #compressorpedal #levelingamplifier #tubeeffects #guitarpedals #guitarfx #effectspedals #guitar #pedalboard #guitareffects  #guitargear #guitarist #knowyourtone #guitarpedal #stompbox #guitarplayer #geartalk #fxpedals #guitars #electricguitar #pedalboards #guitare #guitarra #chitarra
