The ZMX862 six-channel, two-bus mixer from Alto features a compact and portable design, and is ideal for live sound reinforcement applications for bands or speakers, in small to medium venues.
Versatile inputs include two low-noise discrete microphone preamps with switchable phantom power, two stereo input channels with balanced 1/4" TRS jacks for keyboards and drum machines, and a stereo RCA aux input to plug in your MP3/CD players.
Each channel is equipped with a three-band EQ, an FX send for external effects, and a Monitor send to create monitor mixes. They also feature a high-headroom circuitry which preserves your mix's full dynamic range.
The LED metering provides precise visual feedback for hands-on mixing, while the color-coded sections and knobs help you identify and quickly reach for controls in dimly lit environments.

Re: ZMX862 balance control: On channel 5/6 and ...
Re: ZMX862 balance control:
On channel 5/6 and 7/8 there is a "balance" control with a typical left/right setting, but it definitely works differently from the typical preamp control.
I happened to have my left/right output cables reversed. Not realizing those were the ones reversed, I tried switching the left/right input cables on channels 5/6. All that did was when the balance control was moved from in one direction or other it just cut out one channel, and the output was always decreased in the direction of the way the balance knob was moved, despite reversing the input cable. So, it appears that the channel 5/6 and 7/8 balance controls don't change the balance of the INPUTS, but change the balance of the output.
If anyone can correct my understanding of what's going on with the balance controls, it would be good to know.
Asked by: Gerald
Since channels 5/6 are stereo input channels, the balance controls treat that as one stereo out. This means that when the balance is centered at the 12 o'clock position, left input is coming fully out of left output, and right input is coming out of right output. When you adjust the balance knob, the focus of the signal is adjusted to the channel the knob is turned to, decreasing the overall level of the opposite channel and decreasing the overall signal output of the stereo channel.

Can I just hook it up to my phone or do I need a USB?

What else would I need along with this mixer to hook it up to my computer?
Asked by: Anonymous
You would need either an interface or another mixer. It will be cheaper to get a USB mixer that is an interface as well. You always need to access the computer through the USB port. The 3.5mm headphone jack is only good for listening to headphones. This would be a good choice for you and its USB out right into your computer. Use the mains out for your speakers. See below that is a mixer and interface. Just take the USB out into your computer. I assume you have software. Here is the B&H part number B&H # BEQ1202USB.
