The 1202-VLZ PRO is the updated, upgraded version of Mackie’s classic 12-channel compact mic/line mixer. The unit incorporates Mackie’s new ultra-high quality XDR™ (Extended Dynamic Range) mic preamps with the best RFI rejection of any compact mixer design. Added benefi ts include maximum freedom from ground loops and impeccable sonic performance that meets or exceeds the specs of esoteric, outboard mic preamplifi ers. The XDR design is the only compact mixer mic preamp that is totally impedance independent: frequency response does not change even with extremely long cable runs or exceptionally high-impedance mic inputs.
