4 HEAD DELAY SXG-FV1 SPN 1001 board only (no enclosure)

SPN1001 FV1 chip on board is from Profusion PLC.

IMPORTANT: 
Please read about FV-1 / SPN1001 REVERB IC and how it works online before ordering this board.
 
PCB size 55 x 50mm

The board fits Hammond 1590B enclosure.
 
What is on the board:

  1. Audio input 2 pins - signal and ground.
  2. MIX (DRY/WET) potentiometer 
  3. TAPE SPEED potentiometer 
  4. TAPE AGE potentiometer 
  5. FEEDBACK (SWELL) potentiometer 
  6. VOLUME (output level) potentiometer 
  7. 4 HEAD switches 
  8. Audio output 2 pins - signal and ground.
  9. "CLIP" RED LED
  10. "EFFECT ON/OFF LED" - pedal switch green LED
  11. +9V power supply 2 pins - positive and ground.
The delay board is Binson type drum / tape recorder and player. 
Tape runs and you control its running speed with a "TAPE SPEED" 
and tape "quality" wear and tear with a "TAPE AGE" potentiometers.
Each head spaced in a distance. Commutating which head is activated - delay effects changes. 
All 4 Heads can play at the same time or any combination of them.
 
You will receive the board assembled and tested.
If you do not need the potentiometers soldered on a board - please add for me a message making an order.
You will need a low noise power supply +9V for the board.
All connectors are included.
 
How SPN1001 works there are lot of information online, please read before.
 
FV-1 / SPN1001 REVERB IC
The delay board is based on FV-1 / SPN1001 REVERB IC and its original version from Spin Semiconductor. The FV-1 is extremely easy to include in any audio system. For all practical purposes, the FV-1 can be treated as an analog part. Although the FV-1 is fully digital internally, it has been designed with internal power supply bypassing and careful attention to signal pin protection devices so that only a clean power supply and expected analog techniques are required at the PCB level. The Spin Semiconductor FV-1 is a complete reverb solution in a single IC. With integrated stereo 24bit ADC and 24bit DACs, the FV-1 can be treated like any other analog component in your systems  signal path.
 
SAMPLE RATE
The crystal oscillator is designed for the standard 32768 Hz watch crystal. The sample rate of the system will be at this applied rate. At 32768Hz, the ADC and DAC bandwidth will be 15KHz.
 
All you need is to make an enclosure for the delay board.
