The Control Elements . . .
. . . on the front Panel
1. The MONO MIC/LINE Channels
Your THE T.MIX DPM 1122 is equipped with 12 low-noise microphone
preamplifiers with optional phantom power, 50 dB of gain and over
100dB of S/N ratio. You can connect almost any type of microphone.
Dynamic microphones do not need phantom power. Use phantom power
only with condenser microphones but make sure that the phantom power
button is disengaged before connecting the microphone. Phantom power
will not damage your dynamic microphones, so make sure to read the
microphone instructions manual before engaging phantom power. These
channels are also equipped with 1/4“ TRS balanced/unbalanced LINE-
IN plugs to connect line-level instruments such as keyboards, drum
machines and effect devices.
2. MONO Channel INSERT
This is where you connect external sound processors such as
compressor-limiter, equalizers, etc. The insert point is available on the
first 12 MIC channels only. For the other channels you can always insert
the processor in between the sound source (such as keyboard or drum
machine) and the THE T.MIX DPM 1122 input. The insert sockets can be
used as direct-outs to feed the input of a multi-track recorder.
3. STEREO INPUTS
These are channels 13/14 and 15/16. They are organised as stereo pair
and provided with 1/4” TRS phone sockets. If you connect only the left
jack, the input will operate in mono mode, that is the mono signal will
appear on both mix channels. You can use these inputs with a stereo
keyboard, drum machine, etc.
4. MONO Channel TRIM
This control is provided with 2 different indications: One is for the MIC
and the other for LINE levels. When you use a microphone, you should
read the MIC ring (0~-50dB); when you use a line level instrument,
you should read the LINE ring (+15~-35dB). For optimum operation
you should set this control in a way that the PEAK LED (17) blinks only
occasionally in order to avoid distortion on the input channel.
5. STEREO Channel TRIM
When you use a line level instrument, you shall read the ring (+20~-
20dB).For optimum operation you shall set this control in a way that the
PEAK LED (
k
) blinks only occasionally in order to avoid distortion on the
input channel.
6. LOW-CUT Button
By pressing this button you will activate a 75 Hz low frequency filter with
a slope of 18 dB per octave. You can use this facility to reduce the hum
noise infected by the mains power supply, or the stage rumble while
using a microphone.
EQUALISER
There are 3 bands EQ with sweepable MID on all mono input channel
1-12: HI, MID and LOW band.
There are 4 bands fixed frequency EQ on the stereo channel 13-16: HI,
HI-MID, MID-LOW and LOW band. All bands provide up to 15 dB of boost or cut.
