standards that Dangerous Music is renowned for.  The DAC-ST is a stereo D/A converter that allows the engineer 
to monitor from and switch between any one of the five digital sources without interruption.  The source is selected 
from the Dangerous ST Remote and simultaneously routed to the Selected Digital and balanced analog outputs.  Only 
instantaneous switching between sources allows truly accurate comparisons.  (“Am I A/B-ing the mix to the CD, or 
to the CD Player’s Converters?”)  The DAC-ST solves this conundrum elegantly, while delivering the mastering quality 
conversion that you’ve come to expect from Dangerous Music.  Bon Appetit.

1. S/PDIF RCA Input

 

Feature:   Ultra quick digital access for external S/PDIF devices like a field recorder, cd player, synth or 

laptop. 

 

Benefit:  Avoid rack diving with a flashlight duct taped about the head.

2. S/PDIF to Input 1 Button

 

 

Feature:   Upon depressing the switch, SPDIF Digital Input from the RCA jack on the faceplate is routed  

 

 

to Input One.  The default is Digital Input one, accessible via DB25 connector on the rear of the  

 

 

unit.

 

Benefit:  No patchbay required!  Like a 5th input.
Tip: 

,

  The rear Digital Inputs may be utilized for AES or S/PDIF in any combination.  No transformer is 

required.  Simply purchase a snake wired in accordance with the pinout diagrams in the appendix 
of this manual (preferably Mogami Cable of course).  How is this black magic possible?  The S/
PDIF standard is 500 millivolts peak to peak and the AES standard is 5 volts peak to peak.  The 
DAC-ST is happy receiving anywhere from 300 millivolts to 5 volts, well within tolerances, so you 
can keep on mixing the music, while we tame the Danger.

3. Digital Input Selected LEDs

 

 

Feature:   Visual confirmation that a specific digital source has been selected by the Monitor ST Remote.   

 

 

Yellow LED on = source selected.  Yellow LED off = source not selected.

 

Benefit:  Avoid putting post-its on all your gear to remember the combinations-- what?  I already forgot...

  

Operation: The input source is selected from the Monitor ST Remote using the “Additional Switching”  

 

 

buttons.

4. AES LED Lock Indicator

 

 

Feature:  LED lights to confirm that the D/A has locked to the selected digital input.  The D/A has an
