PRO MIXER DX2000USB User Manual
7.  Sub Bass
The sub bass output  
(63) 
 on the back panel comes with two rotary controls, 
one for output LEVEL  
(62) 
 (max. +22 dBu) and another for adjusting the crossover 
frequency of the low pass filter, CROSSOVER FREQUENCY. 
(61) 
 (low pass filter 
variable from 30 Hz to 200 Hz). This can be used to drive a very low frequency 
sound system in a studio or club to provide added bottom end.
◊ 
Sub bass units are often useful in small studios where there is no room 
for large extended-range monitors in front of the mixer.
8.  Controlling External Devices
8.1  Desk lamp
A connector  
(37) 
 for an optional standard 12 V working light is offered, 
immediately above the bargraph meters. You should only use 5 Watt lights. 
8.2  Remote control of audio devices
We have not yet mentioned the big non-latching TRACK START buttons  
(20) 
 
immediately below the faders on channels 3 to 7. These have nothing to do with 
the audio side of your desk. They are REMOTE CONTROL buttons for interfacing 
with certain audio sources such as CD players, CART machines etc. which have 
remote jacks built into them. Please refer to the manufacturer’s specifications 
to see if your equipment conforms to this protocol. If it does, connection to 
the DX2000USB is by simple jack leads  
(55) 
 on the rear panel. Please ensure 
that your equipment’s remote control output does not exceed 30 V DC/50 mA 
(This is unlikely!).
The advantages of REMOTE CONTROL are purely ergonomic—you don’t have 
to stretch over the desk to bring in an audio file, jingle or music CD in on cue. 
For clarity of function it is best to associate each REMOTE button on the 
DX2000USB with the device supplying audio to the stereo channel immediately 
above it. Otherwise things could get very confusing! Please refer to the 
specifications of the equipment you want to connect.
8.3  Sound-to-light
A mono audio output  
(60) 
 is provided for connection to lighting controllers with 
a sound-to-light facility. Connection is via a standard ¼" jack on the back panel. 
Sensitivity is conveniently adjustable from the DX2000USB by the LIGHT LEVEL 
knob  
(40) 
 to the left of the bargraph meters. Too high, and the lights will stay on, 
too low and they won’t flash at all. Adjust LIGHT LEVEL until lights flash in time 
with the music.
