DESCRIPTION


BODE SHIFTER 1.1

Added: Pitch and FM (Frequency Modulation) inputs
Added: Input and Output volume controls on Panel B
Added: Frequency Drift - the drifting amount will increase by increasing the amount of frequency shift

*The automation now works correctly.

BODE SHIFTER 1.0

A digital reproduction of a legendary and rare analog frequency shifter.

A frequency shifter is a highly specialised module capable of shifting the spectrum of a signal by a fixed amount. This is very different from a pitch-shifter and other effects such as ring modulation or frequency modulation.

The BODE SHIFTER allows you to shift the frequency linearly within a number of ranges, the widest of which shifts the signal by approximately ±5kHz at its maximum setting. Upwardly shifted (B) and downwardly shifted signals (A) are available simultaneously, both as independent signals, and as a user-defined mix of the two (MIX).


AMOUNT OF SHIFT:
Shifts the frequency of the incoming signal between the maximum and minimum ranges shown.


SCALE:
The scale switch has six positions, as follows:

Zero
None of the pitch shifting mechanisms have any affect upon the signal.

EXP
The input frequency is multiplied by a factor to create the upward shifted signal, and divided by
the same factor to create the downward shifted signal. The maximum amount of shift is
approximately ±2kHz.

5, 50, 500, 5k
The input frequency is shifted upward and downward by an arithmetic amount. The maximum amount of shift is approximately ±5Hz, ±50Hz, ±500Hz, and ±5kHz respectively.


MIXTURE:
You may control the relative proportions of the downward shifted
('A') signal and the upward shiftet ('B') using the associated MIXTURE A/B knob.

The relative proportions of both signals will be send to the 'MIX' Out.


ZERO ADJUST:
In Analog World it is used to calibrate the 'Frequency Shifter Module' each time you change the SCALE setting. To do so, set the Pitch Control knob to Linear "0" (the 12 o'clock position) and then rotate the ZERO ADJUST until the associated LED stops blinking. This shows that
there is no shift in the A or B signals, and that the RANGE is correctly centred.

Can be also used as a second stage to shift and modulate the AMOUNT OF SHIFT. The amount of this Control is ±10% of the SCALE control.


SQUELCH:
When the input signal drops below the threshold, a noise gate cuts off the output, thus minimising unwanted noise and artefacts generated from background noise.

Squelch threshold
You may set the threshold between 0dB (at which point all signals are rejected) and -60dB (which gates the output only when the very quietest signals are received at the input).

Marius, I see you have taken a sabbatical from working on Blocks, just wondering if it's permanent?
