Omnitronic TRM-402 4 Channel Rotary Mixer
A question here arises that why 4 channels for a rotary mixer? As we all know, older mixers used faders to control the sound, but this rotary mixer uses knobs for that very purpose. Imagine having a mixer that is expensive yet does not produce quality sound. The knobs here in the 4-channel rotary mixer ensures a high-quality sound.
Flat transitions are difficult to set with conventional mixers (having faders), but the large knobs of 4 channels provide easy and smooth transitions. In a 4-channel rotary mixer, all 4 channels can be easily switched between phone sources or inputs and line. Integrated isolator along with 4 channels ensure treble and bass that creates quality mixing. Thus, TRM-402 is among the best mixers available on the market.
Omnitronic TRM 402 Test
TRM-402 look at first glance, is quite impressable. There is a power socket for the connector and a power switch at the back of the rotary mixer. Next to it you can find the first two channels strip with the connections. Also, two stereo pairs for each line are located here. In other words, each channel has its very own grounding screw.
There is XLR in the middle as a way out for the Booth as well as for the Master. As there is no compulsion to jack, XLR outputs are preferred. But if you want to connect speakers via amplifiers, master or booth, either one can be handy here. There is also a rec out option. The mixer comes with two microphone inputs for the ‘’I need a microphone’’ people. One XLR socket is located on the front left and other is located on the top. Both are connected to a potentiometer (on top) in order to control level. The LED and an on – off switch are also located on the top of the mixer. At the back, there is a microphone input on the left, and two headphone outputs on the right.
Now moving towards how you should use the mixer. Simply connect the player, set turntable gain and you are done. One important thing you should keep in mind is that level metering is only applicable to the master sum – you can fully extend and then level, but you might lose the headroom this way.
The channels of the mixer offer to equalizers – high and low, each with centre gird. Both the EQs sound soft in cut. Also, the master sounds pretty good – not scratchy. Isolator does the job of killing the extra bass and provide the required frequency of the bass. In the test, it has been proved that the TRM-402 is the perfect choice for clubs, parties and as well as homes with a reasonable sound performance.
Omnitronic TRM-404 vs 202
As we all know that Omnitronic has launched some excellent inventions including mixers for DJs. This article has mentioned all the features of the TRM-402, but it is the advanced version of the TRM-202.
TRM-202 by Omnitronic has been popular among DJs of electronic music all over the world. But as compared to TRM-402, it is certainly a step below and the build quality is also lower. Talking about the channels incorporated in each, the core has remained the same, the channels have grown – 2 input channels in TRM-202 whereas 4 input channels in TRM-404. 2 channels do not produce the same sound quality as 4 channels that is why TRM-404 is much better than TRM-202 in sound value.
The TRM-404 produces a quality sound whereas the TRM-202 cannot compete it here. However, it also features a rotary mixer instead of faders. One thing you should keep in mind is that its ergonomic design is the plus point. Using Omnitronic TRM-402 instead of TRM-202, you will surely get the full hi-fi experience. the TRM-202 is relatively lighter than the TRM-402 (weighs 7.01 pounds). Also, there were few imperfections on the cover plate of the TRM-202 (likely due to paint drop residue) but these are not on the TRM-402, as we are already very much in detail.
