The Design of the D-Sonic M3-5400-7
When the box for the M3 arrived, I knew I was going to be dealing with a serious piece of equipment. Weighing in at 58 lbs and measuring over 18" wide and 15" deep, the unit immediately commands attention.
The build quality of the M3 appears very solid and well constructed. Dennis informs me that power allocations to each channels were determined by measuring the normal mix that D-Sonic measured in movies and concert films. As such, each channel is labeled on the back of the unit. Both XLR and RCA inputs are included. The speaker outputs are gold plated and appear to be of very high quality.
Two power ports are also included to deal with the power needs of an amp outputting this kind of wattage. D‐Sonic includes two high quality, low gauge power cords with each unit. A 12-volt trigger input is also included so that the unit can go into sleep mode when not in use.
The front of the M3 is unassuming - all black with a small blue light under the logo indicating that the unit is receiving power. This light remains on whether or not the unit is in sleep mode or powered up. From production photo's that Dennis has sent me, it appears that my M3 a pre-production model. This unit had a 525-watt ICEpower module for the center channel, different from the non-ICEpower modules used in the other 7 channels. The production model will use the same newer tech for all 7 channels. You will also notice slight differences in the logo in production photos vs. what I had. Otherwise, Dennis assures me that all components are exactly the same as what you'll see currently shipping from D‐Sonic.
The M3 is passively cooled – as such there are no fans or other moving parts to contribute any unneeded noise.
