Mackie B248 Recording/PA Console (24x8x2)

The 8-bus Series was designed to eliminate the last barrier between you and audio creativity - the 32x8, 24x8 are capable of sound quality equal to or better than that of $100,000 consoles. Mackie's 8-bus consoles have recorded more platinum albums and major motion picture soundtracks than any other mixer in their class - they set the standard for affordable 8-bus consoles.

Excellent for project studios and digital multi-track recording when combined with digital multi-track or hard disk recording systems. A Mackie 8-bus console not only creates major label CDs, but also major motion picture soundtracks and network quality commercials.

Features include low-noise/high-headroom mic preamps on every channel, as well as channel inserts and direct outs. In the channel strip you'll find Mackie's truly musical EQ - with Hi and Lo shelving EQ, parametric Hi-Mid, and sweepable Low-Mid EQ - as well as our Low Cut Filter, which allows you to eliminate mic thumps and room rumble from your mix, and use your EQ for music and vocals.

With Mix B, "in-line monitoring" is a breeze. Six aux sends and 6 aux returns allow you to use all the effects you want. And the 8-Bus's complete talkback and phones level controls make communicating with the talent a snap. There's much more:

When you get right down to it, the 8ÝBus Series of recording consoles is a value at many times the price. The fact that artists and producers of every shape and size have sworn by them means when you buy an 8ÝBus you'll be in good company.
