DANGEROUS MUSIC

1. Digital In/Thru

Feature:  The rear panel of DAC-ST sports a 25 pin D-Sub connector (commonly called a DB25) wired to the 

Tascam AES digital standard.  Remember, this connector can be wired for AES or S/PDIF or any 
combination of the two.  The pinout wiring diagram resides in the appendix of this manual (vs. your 
appendix, in case it was removed).  

Benefit:  This is a 4 channel digital input and through.  Now you can (A) switch between sources while 

monitoring with the same converter and (B) pass the signal forward to it’s next destination.  

“So What?” (A)  Here’s why this is mad cool.  Monitoring all your digital sources through the same 

converter levels the playing field.  

Example:  “What’s all that extra top end on the CD pressing?”  Might just be “crunch” generated from the 

D/A converter.  “Why can’t I pinpoint the ride cymbal?”  Jitter from that cheap CD player could 
be smearing the image.

Tip: 

Dangerous  Music  is  so  concerned  about  the  inviolability  of  your  audio,  that  the  DAC-ST  will 
actually clean up jitter from squalid incoming sources and pass it through with defined edges.  The 
instantaneous lock range is 32 kHz to 192 kHz.

“So What?” (B) Passing the signal forward opens up a myriad of possibilities. 
Example:

 •Monitor the main mix from Pro Tools.  Pass this on to external hardware.

 

•Compare the effected version.  Pass through back into Pro Tools and effect with plug-ins.

 

•Compare against the original and hardware effected versions.  Pass through to an external 

recorder.

 

•Compare the output of the final recorder with all the aforementioned sources.  Now make 

accurate, critical decisions based on true comparisons. Pass through to a digital meter or see tip 

below.   

2. Selected Digital Out

Feature: 

 

Connect a digital meter here.  

Benefit:  Every time you change DAC-ST sources, the digital meter will follow the audio currently being 

monitored.

Tip: 

Connect to an external recorder to create multiple versions for comparative listening.

3. Analog Out (stereo)
