Overview 

 
The 2Bus LT is a 16x2 summing amplifier designed to help the users of digital audio 
workstations achieve better mix performance through the use of existing equipment in 
their studios. The designers and their colleagues have noted that while DAWs offer 
unprecedented flexibility in multitrack recording and editing, the resulting mixes from 
these systems generally don’t equal those of high-end analog recording systems in terms 
of sound quality, preservation of spatial detail, and ‘no latency’ ergonomics. In today’s 
portable environment and with the cost of maintaining and housing legendary recording 
equipment, the choice of a big desk is impractical for many users of DAW systems. We 
want to bring together the best of both worlds. It is in this spirit that the Dangerous 
engineering team is designing and manufacturing an exciting array of summing, mixing, 
monitoring, metering, and mastering equipment to meet the needs of today’s recording 
engineers, producers, and artists. 
  

Hook up 
 

 

 
The 2Bus LT is designed to mix the outputs of two eight channel D/A converters to a 
stereo recorder (16x2).  The 2Bus LT is easily stackable to increase channel numbers and 
system functions when linked with another 2Bus LT, Mixer, Monitor, or 2Bus. All the 
XLR’s are pin 2 hot and the connector groups are described as follows: 
 

EXPANSION IN 

Patch from the Main Output of a 2Bus, LT, or Mixer to sum into 
the mix bus. 

 
IN 1-8, IN 9-16

 

The inputs are arranged into eight sets of XLR’s. They can be 
plugged into directly from the D/A converters but system 
flexibility (and fun) goes way up with the addition of a patch bay 
for ease of outboard equipment use. The pin out is on page 10. 

 
REMOTE ONLY 

This connector is not used. 

 
DC IN 

 

It is best to make sure that the power supply is unplugged when 
connecting the DC power cable to prevent damage to contacts in 
the connectors. 

 
MAIN OUT 

The Main Output feeds the mixdown A/D converter. 

 

MON OUT 

These jacks have the same signal as the Main Outputs. They are to 
feed the Dangerous Monitor or other monitor section.
