PRO MIXER DJX750 User Manual
(42) 
The DJX750 features an integrated effects loop for the connection of an 
external effects device. The MONITOR signal is taken at the SEND output 
and routed, for example, to a reverb processor. Thus, the signal at the SEND 
connector is identical to the headphones signal and is selected with the 
MONITOR CUE buttons  
(16)
.
(43) 
The externally processed signal is added to the MASTER output signal via the 
RETURN connectors. The effect signal volume may only be adjusted at the 
output control of the effects device itself.
(44) 
The MASTER output is for connecting to an amplifier and can be adjusted 
with the MASTER fader  
(18)
.
◊ 
Always turn the power amps on last to avoid inrush currents that can 
easily damage your speakers. And, to avoid sudden and unpleasant 
surprises for your ears, make sure there is no signal at the DJX750 
before turning on the power amps. To be sure, slide all the faders to the 
bottom and switch all controls to the zero position.
(45) 
The BOOTH output gives you an additional option of connecting an amplifier 
in order to, for example, feed the signal into your monitors or to bring sound 
to an extra area. The BOOTH output level is regulated by using the BOOTH 
LEVEL control  
(20)
  of the MASTER section.
(46) 
Using the TAPE output you can record your music by connecting devices such as 
tape decks, DAT recorders etc. Unlike the MASTER output, the output volume is 
fixed, making it necessary for you to adjust the input level on the recording device.
(47) 
The POWER switch powers the DJX750 on. You should always make sure that 
the POWER switch is in the “Off” position when initially connecting the unit 
to the mains.
◊ 
Merely switching the unit off does not mean that it is fully disconnected 
from the mains. When not using the unit for prolonged periods of time, 
please unplug the unit’s power cord from the power outlet.
(48) 
This is the connector for the power cable. This is where the advantage of a 
sophisticated internal power supply can be seen: the pulse behaviour of each 
amplifying circuit is mainly determined by the voltage reserves available. 
Each mixing console is equipped with numerous operational amplifiers 
(op amps) to process line level signals. Due to limited output of their power 
supplies, many mixing consoles show signs of “stress” when subjected to 
heavy loads. But not your DJX750: the sound is always clear and transparent.
(49) 
FUSE HOLDER / VOLTAGE SETTING. Before connecting the unit to the mains, 
ensure that the voltage setting matches your local voltage. Blown fuses 
should only be replaced by a fuse of the same type and rating. On some 
units, the fuses holder can be switched to one of two positions, i.e. 230 V and 
120 V. Please note: should you desire to operate the unit outside Europe at 
120 V, a higher fuse rating is required.
◊ 
To disconnect power from main, pull out the main cord plug. 
When installing the product, ensure that the plug is easily accessible. 
If mounting in a rack, ensure that the mains can be easily disconnected 
by a plug or by an all-pole disconnect switch on or near the rack.

3.  Initial Operation
◊ 
Ensure adequate air supply and to avoid overheating do not place the 
unit near radiators etc.
◊ 
Before you connect your unit to the mains, please make sure that your 
local voltage matches the voltage required by the unit. The fuse holder 
on the mains connector has 3 triangular markings, with two of these 
triangles opposing each other. The unit is set to the operating voltage 
printed next to these markers and can be set to another voltage by 
turning the fuse holder by 180°.

Caution
Please note that when operating the unit at 120 V, a higher fuse rating is 
required. Please refer to the “Specifications” for details. 
If you set the unit to a different mains voltage, be sure to  use a fuse of the correct 
type and rating. Please refer to the “Specifications” for details.
◊ 
Blown fuses must be replaced by fuses of the correct rating! 
Please refer to the “Specifications” section for the applicable rating. 
Before you change the fuse, switch off the device and pull the plug to 
avoid electric shock or damage to the device.
The mains connection is made using the enclosed power cord and a standard IEC 
receptacle. It meets all international safety certification requirements.
◊ 
Please make sure that all devices are properly grounded. For your own 
safety, never remove or disable the ground conductors from the devices 
or on the power cords. The unit must always be connected to the mains 
outlet with a protective grounding connection.
◊ 
The sound quality may diminish within the range of powerful 
broadcasting stations and high-frequency sources. Increase the 
distance between the transmitter and the device and use shielded 
cables for all connections.
