[0.19 lb] Overall, excellent.

I only wish they offered a model with five channels, mini stereo jacks on all inputs, and have one channel with built in audio isolation transformer. Obviously, that would cost more, but then it would go from a great mixer to a perfect one.

[2.7 x 2 x 1.2"] RDL makes a very good series of mixers. This line mixer works very well and saves space. Great for mixing line level inputs

[0.19 lb] Nice and simple DA that works well for balanced signals. Wish it came with it's own PSU but eh.

[0.19 lb] Just needed to have one ceiling mounted microphone output go to two destinations. Nothing fancy. That describes this item - nothing fancy. It gets the job done in a small space, don't need special training to install- it's easy!

[0.19 lb] I've always loved using these in radio, so when I had to build a microphone distribution amp, this was my first and only choice.

[2.7 x 2 x 1.2"] We installed this near the sound desk as a big visible vu meter of the output of audio going to our livestream. It works quite well and doesn't seem to add any noise to the system (or if it does, its negligible enough to not matter once the audio is compressed to the livestream). Plus, its 5x cheaper than anything else like it!

[0.19 lb] Have you ever become frustrated when folks power up an amp rack while a source is delivering a full-scale signal to it? The large LEDs in this unit are eye-catching enough to act as a console output pilot light which might catch enough attention to avoid the situation. There are even more useful applications for the unit... so don't write it off as a toy before trying it.

In our application, a 52kW amp rack is controlled by an innocent-looking key switch. Imagine that someone turns off the keyswitch and then uses the mains level controls as a handy headphone volume knob while the amps are off. Without the eye-catching LEDs displaying mains level, its easy for the next person to activate the keyswitch, deafening those in the path of the 52kW amplifier output.

[0.19 lb] This item worked as expected. It was purchased to amp a line level signal going into an amp. Just make sure you purchase the power supply as well. It is sold separately from the device itself.

[2.7 x 2 x 1.2"] I bought this from B&H in June 2014. It's now Dec 2019, and this amp is still performing flawlessly. I use it to combine 3 different audio sources into a single output that I distribute to various powered speakers throughout my house. I like that I can set the amplification for each source to make each source equal volume on the output. That way I don't have to constantly jockey the volumes when I play a new source. I also love that I don't have to switch anything around. I can play all three (or four) source at the same time if I want, or just stop one and start the other without having to touch any input switches or anything. I have my computer, my bluetooth adapter, and my record player pre-amp all on this thing, and I can easily just start playing the new source without touching anything. I love it. I have it mounted vertically behind the little table that holds the livingroom computer so if I do ever need to adjust anything, it's quick and easy. I do sometimes use the knob to adjust the volume of my record player input.
