PAiA Documentation

I thought that it may be helpful to list where to find documentation for the 2720 and 4700 synthesizer. I'm going to link to the pages that the manuals/schematics are stored on and not the direct download.

2720-1 VCA (schematic only)
2720-2a VCO (schematic only)
2720-3B Band Pass Filter (schematic only)
2720-3L Low Pass Filter (schematic only)
2720-4 Function Generator (schematic only)
2720-5 Control Oscillator / Noise Source
2720-6 controller Vinyl Strip/S&H
2720-7 Power Supply
2720-8 Keyboard manual (13.6 MB)
2720-8 Illustrations Supplement (5.7 MB)
2720-9 Glide manual (5.9 MB)
2720-11 Envelope Follower
2720-11 Envelope Follower (schematic only)
2720-12 Inverter/Buffer
2720-12 Inv. Buffer (schematic only)
2720-14 Sine Converter/PWM (schematic only)

For documentation regarding building the 2720 modules read: Building the 2720 series modular.

If anybody has links to the scans of the manuals that I don't have please provide a link and I'll post them here.

Current Draw for PAiA 2720 and 4700 Modules

2010-05-30T10:40:00.000-07:00

I thought that this info may be helpful to others. Below is the current draw (the amount of amperes) for most early PAiA modules. An amp, as you probably know, measures the amount of energy being consumed by each module. Make sure you don't get amps and voltage confused. There's a lot of great resources out there for learning about these units of measurement.

PAiA 2720 Modular Series Synthesizer:
2720-2 (VCO): +/-9v @25ma
2720-5 (Control Osc.): 18v @ 1.75ma
2720-9 (Glide) +/-9v @1.5 (each)
2720-11 (Env. Follower): +9v @6.5ma, -9v @ 7.5ma
Keyboard +9v@ 1.5ma. -9v @3ma, 18v @ 1ma

- If anybody needs any of the other 2720 series modules measured, let me know. I'm going to get around to doing the modules (that I have) that aren't listed at some point..

PAiA 4700 Series Modular Synthesizer:
4710: +18v @10ma, +9v @ 1.5ma, -9v @7ma
4711: +/-9v @ 4ma
4712: +/-9v @ 3.5ma
4720: 9v @ 20ma
4730: +9v @ 15ma, -9v @25ma
4740: +18v @ 17ma
4750: 18v @ 1.75ma
4760: +18v @ 50ma, +/-9v @ 1ma
4762: +/-9v @ 25ma, 18v @ 25ma*
4770: (Watt Block): 117v 50/60khz, +/-9v @100ma or 18v @100ma (out)
4780: +18v @50ma, +/-9v @1ma

* Includes 2720-8 and 2720-9 circuitry.
