standard in the recording industry. Two independently controlled audio channels make the 
TC1280 ideally suited for any system requiring precise control over audio delay. Uses include 
concert delay towers, balcony delay in theatres, mastering delay, audio for video format 
conversion, matching of video processing delays, etc. anywhere that high quality time delays 
are desired with minimum effect to signal quality.

device. 

 

• 

Dynamic range > 100 dB is excellent for live sound performances. 

 

• 

Absolute stereo phase linearity within 2 microseconds. 

 

• 

Delay time increments adjustable down to 5 microseconds for exact adjustments needed
