TLN-866 Gate Processor

Gate generator/delay & pulse stretcher

The TLN-866 Gate Processor is a gate delay, a pulse stretcher, and a gate generator. Any signal that momentarily exceeds +1.5V can be used to "arm" the processor and create a GATE signal at the output. This output GATE is held for the HOLD time but doesn't appear at the output until the DELAY time has passed. HOLD and DELAY times can be from 5 milliseconds to 10 seconds (or longer if you wish). A handy pushbutton on the front panel addresses the need for a manual GATE signal in your synth. A bicolour LED is used to indicate the processor's status: RED when the processor is armed and GREEN when the output goes high.

The TLN-866 can be used to create an echo of a gate signal. For example, if the HOLD and DELAY times are 4 seconds, a one second long gate signal at the input will result in a one second long gate signal at the output 3 seconds after the input gate has gone low. Spooky.
The dual TLN-866 pictured at left features two independent channels (A & B) with the following controls:

• HOLD A/B: sets the length of time the output signal is held high after the input has gone low, from one millisecond to 10 seconds (or longer).
• DELAY A/B: sets the delay time before the output signal goes high from one millisecond to 10 seconds (or longer).
• IN A/B: input signal, any signal that exceeds +1.5V can be used to arm the processor.
• OUT A/B: the held and delayed gate signal.
• GATE A/B: pushbutton to manually arm the processor.
• LED A/B: bicolour LED is RED when the processor is armed and GREEN when the output goes high.
