General
The Mackie ProFX v2 series is a range of complete, durable analogue mixers with outstanding sound quality. Apart from the ultra-rugged construction, the Mackie Vita preamps are an important feature that virtually guarantee noiseless amplification of your microphones. The Mackie ProFX12v2 contains no fewer than six of these high-quality preamps, hence the six XLR inputs. Stereo sources can be connected using the four jack inputs. Moreover, the sixteen high-quality digital effects, the built-in USB audio interface, and the 7-band master EQ should prove to be very handy.
ProFX12v2: Inputs
The ProFX12v2 is a live mixer that is extremely suitable for smaller musical groups. It's possible to connect an electro-acoustic (bass) guitar to the Hi-Z input, a keyboard and laptop to the stereo inputs, and multiple vocal and instrument microphones to the five remaining XLR inputs, for instance. A balanced mix is easy to make using the 60mm volume faders and 3-band equalizers on each channel. In addition, you could use an effect like reverb or chorus to add spaciousness to your sound. You can even adjust the acoustics with the master EQ.
The Full Package
The more experienced audio engineer will immediately notice how much the ProFX12v2 has to offer. This complete mixer features an output for a floor monitor, for instance, of which the mix is adjustable via the aux controls. The overall volume is easy to adjust with the monitor fader, and the RCA tape I/O has its own handy volume control. Other useful features include the break switch (to mute all channels), the phantom power supply for condenser mics, and the USB interface for digital recording or playing back a stereo mix via your PC or Mac.
