Overview 

 
The 

Monitor

 is designed to be the cornerstone of a recording studio by 

providing a convenient method for listening to and metering the different 
stages of the recording process. Careful attention to detail has resulted in a 
unit of stunning ergonomic clarity and unprecedented performance in a 
compact enclosure. The user will discover that the ability to select between 
different analog and digital sources as implemented in 

Monitor

 allows 

accurate assessment of program material without quality differences in the 
signal paths clouding the user’s judgment. 
 
The built in digital to analog converter provides a solid basis for comparing 
digital sources directly without being subjected to the inevitable differences 
in calibration and sound quality between the converters in separate pieces of 
gear. Many times, the engineer can be fooled by differences in sound quality 
of “clones” (DAT from a CD) because the different brands of equipment 
don’t sound the same even though the data on the carriers is the same. The 
topology of 

Monitor

 lets the engineer concentrate on the music and not the 

process. 

 

Hooking up your Dangerous Monitor 
 

 

 

The connectors on the back of 

Monitor

 are arranged into 5 groups. The first 

is the 

AES IN

 and 

THRU

 connectors. The user is to plug AES signals into 

the female XLR connectors. Up to four devices are selectable for routing to 
the built in D/A converter and digital meter feed. The XLR male connector 
provide an uninterrupted through. 
 
 
The second connector group is the “meter feeds” group. These jacks allow 
the selected analog and digital sources to be sent to meters and/or phase 
scopes to allow visual aid to the monitoring process. A breakout cable is 
provided for the 

A-MTR

 feed.
