cursor will move to tens of hours. Press the up or down key to adjust tens of hours. 

Then press the right arrow to move to hour units and adjust using up/down. The

Note: The timecode generator is not crystal locked and may lose or gain a few 

seconds per hour, it is intended as a test not a reference generator, it may be

More/Tone Loop 
 

Tone loop enables output tone output and audio input at the same time. Input and 

output signals may be selected to analogue or AES formats with adjustable input and 

output gain and adjustable frequency. This is useful for testing operation of external 

equipment, checking frequency response etc. Analogue signals are output on the left 

channel output XLR and input on the left channel input XLR. AES signals are output 

on both AES channels and input may be selected to monitor/meter left or right 

channels.
