The MM 8z features eight stereo Inputs. Each of the four assignable buses contains its own three band EQ, allowing separate equalization of different sources. The four faders are grouped in two pairs, allowing a custom mix of two input sources on each side of the crossfader. One of the new features added to the MM 8z are two Pre/Post crossfader assign switches. They allow individually assigning source 1 or 4 to Pre- or Post-crossfader. This allows another mixer, drum machine, synth or wireless mic to be controlled from source 1 or 4, while sources 2 and 3 still use the MM 8z's Crossfader. This powerful new feature greatly increases the flexibility of the MM 8z, making it one of the most capable mixers in it's price range. The second feature is the addition of a Crossfader Contour control. This allows adjusting the 'shape' of the Crossfader response from a gentle curve for smooth, long running fades, to the steep pitch required for top performance cut and scratch effects. Active Crossfader* technology combines state of the art voltage controlled amplifier design with a professional quality crossfader control. This combination sets new standards for performance, reliability and serviceability. Virtually all crossfader noise is eliminated. Channel to channel crosstalk is greatly reduced and the off isolation of the faded channel is greatly increased. Active Crossfader technology dramatically increases the service life of the crossfader. In the unlikely event of crossfader failure, there is no loss of signal. If a crossfader becomes rough or noisy, it may be 'hot-swapped' during a performance with no interruption of the audio signal. Simply use the input faders to set the audio levels while the crossfader is out of service. The crossfader may be replaced with either a 60 mm version or a 45 mm version, your choice. Each of the four Phono (RIAA) Inputs switch to Line Level via rear panel switches. Both the Main and Aux Mic Inputs route through Bass and Treble controls. The Main Mic input has an Effects Loop. The main program signal includes a stereo Master Loop for equalization or processing. The Tape Output can be switched to exclude the Master Loop signal and record the unprocessed program signal. The MM 8z doesn't scrimp on its powerful Headphone Cueing system in which one or more channels may be cued at one time. The metering can be switched to monitor stereo main output or mono cue on one side and mono program on the other. The MM 8z's recessed top mounted jacks provide room for cabling in tight DJ coffins or racks without sacrificing its compact 4" depth.
