"The PAiA 9700 Series takes a decidedly high level, systems approach to Synthesizer Module design. Rather than individual elements such as a single VCO, VCA or Envelope Generator, each PAiA module combines multiple elements and a powerful patch-over hardwired normaling scheme behind a single compact panel. Common synth voices can be realized with few patch cords but elements can also be accessed individually for maximum versatility in creating complex, unique timbres. A lot of synth power gets packed into a small space at a low cost. Even a "small" system of only four modules, such as the P9700S, provides the sound generating power of as many as 15 conventional modules, including:

2 VCOs
2 VCFs
2 VCAs
1 Balanced Modulator
1 Noise source
2 AR Envelope Generators
1 ADSR Envelope Generator
MIDI to CV Converter
Glide Processor
CV Scale/Offset Processor
Power Supply

System level design also improves performance and lowers cost. Local voltage regulation and Star grounding on and between modules means a low noise floor and no parasitic modulations or interactions such as oscillator locking. Distributing costs like circuit boards, panels and power connectors across multiple elements dramatically lowers per element cost.

All modules are scaled for 1Volt/octave Control Voltages with standard 100k ohm input impedance. Nominal signal level is approximately +10dB. Modules are designed for ±18V. unregulated bipolar power but ±15V. regulated supplies can also be used.

FracRak accessory kits have heavy duty 1/8" black anodized and screen printed aluminum panels that are 2U high (5-1/4") and provide 1/8" phone jacks for patching. "
