. . . on the rear Panel

50.  AC Inlet with FUSE Holder

Use it to connect your DPM 1122 to the main AC with the supplied AC cord. Please check the voltage 

available in your country and how the voltage for your unit is configured before attempting to connect your 

unit to the main AC.

51.  POWER ON/OFF Switch

This switch is used to turn the main power ON and OFF.

52.  VOLTAGE Selector

There are two kinds of voltages for your operation. From this switch you can select the voltage at 

100~120VAC or 220~240VAC. Always set this switch according to the voltage available in your country.

53.  SPEAKERS Jacks

These jacks are used to connect speakers. They are configured with 4-way speakon connectors and 1/4” 

phone jacks. You can determine the signal that is output to these jacks according to the setting of the 

AMPLIFIER MODE select switch.

Note:

 In order to avoid damage to the built-in amplifier, please pay attention to the allowed impedance of 

the speaker. Very low load impedances may damage the amplifier.

Installation and Connection

Ok, you have got to this point and you are now in the position to successfully operate your DPM 1122. 

However, we advise you to read the following section carefully to be the real master of your mixer. Not paying 

enough attention to the input signal level, the routing of the signal and the assignment of the signal will result 

in unwanted distortion, a corrupted signal or no sound at all. So you should follow the following procedure for 

every single channel:
1.  Turn down all input and output gain controls.

2.  Connect phantom powered microphones before switching on the +48 Volt phantom power switch.

3.  Set the output level of your THE T.MIX DPM 1122 or the connected power amplifier at no more than 75%.

4.  Position EQ controls on middle position.

5.  Position panoramic (PAN) control on centre position.

6.  Increase the input gain properly for maintaining the good headroom and ideal dynamic range.

7.  Depending on the actual application, turn slowly the input and output level controls for obtaining the 

maximum gain before distortion.

8.  Now repeat the same sequence for all input channels. The main LED meter could move up into the red 

section. In this case you can adjust the overall output level through the main mix control.
