TZ Dual VCO

Dual thru-zero VCO with VCA controlled FM input

The TZ Dual VCO is two full featured VCOs on in a single 16HP module. Both VCOs output sine, square, saw, triangle and PWM wave forms. Each VCO also has thru-zero and exponential FM input. The type of FM is selectable using a toggle switch. An important feature of TZ Dual VCO is the FM input for each VCO can be control by a VCA input. A potentiometer adjusts the overall maximum of the FM input while the VCA provides an amplitude envelope.

Each VCO has the following inputs:
* 1V/Oct
* PWM CV
* FM signal
* FM signal VCA

Each VCO has the following wave form outputs:
* Sine
* Square
* Saw
* Triangle
* PWM
*
Each VCO has these adjustment knobs:

• Coarse
• Fine
• PWM
• FM amount
• The upper VCO can be synced with the square wave of the lower VCO. A three position toggle switch is used to select hard sync (up), soft sync (down), or no sync (center).

Current requirements - 130mA +12V, 130mA -12V
