DJ Equipment Mixers – This is one for you!
Saturday, February 20th, 2010I enjoy making recordings of my children’s piano and band concerts. Usually, I can find electrical power close by, but in cases where I can’t, it’s really nice to have the option of recording 100% via battery power, and the UBB1002 is one of just a few mixers that offer that capability.
I’ve only used mine with battery power once, but it performed beautifully, providing 18v of phantom power to my Rode NT5 mics. I ran the output of the mixer into a bus powered USB audio interface that was connected to my laptop running on battery power.
I have used a software spectrum analyzer (from [...]) to measure the frequency response and noise levels of the mixer, and it is _very_ flat. The eq controls also do an excellent job of only altering the specified frequency range. The mixer is quiet as long as you pay attention to your gain structure and keep the sliders at or below 0 dB.
If you’re experiencing excessive hiss, you’re probably feeding the mixer a signal that is too low. Try increasing the output level on your source or adjusting the gain control on the mixer. You really don’t want any of the sliders to be above 0 dB! Oh, also the output is line level, so not intended to feed the microphone input on a laptop PC. You _really_ need an external audio interface like the UCA222, FCA202, or (better) a Creative E-MU 0202 USB that accepts line level signals. If you’re using an ASIO driver on Windows, n-Track Studio 6.0 does a nice job as recording software and can take full advantage of the hardware capabilities of your audio interface, up to 24-bits, 192 kHz.
