The MZ-372 allows multiple audio sources (19 total) to be mixed, muted, and routed to 2 redundant outputs, controlled by familiar volume sliders and assignment buttons. Input signals can be inserted via 6 audio channels, each consisting of 2 sets of unbalanced RCA stereo pairs, and 6 XLR inputs for a total of 12 sets of RCA inputs and 6 XLR inputs. In addition, channels 2/3/4 can be set to accommodate phono-level signals for use with a turntable. Lastly, and located conveniently on the front panel, one additional XLR input is available driving a studio quality mic preamp and ducking circuit for easy voiceover and announcement work.
Multiple Zone Outputs
Twin outputs each feature a combination of balanced XLR or RCA unbalanced connectors for easy integration into virtually any audio system. This flexibility allows combinations of microphones, CD/DVD/Blu-ray players, instruments - or any other audio source - to be selected or muted, and sent simultaneously to the dual outputs, each with it’s own volume control. Finally, the convenient "Talkover” function will automatically lower any mixed channel source so the microphone connected to the front panel can easily be can be heard in whichever zones you choose.
Easy, Immediate Control
Familiar volume sliders, switches/buttons, EQ knobs, and mute buttons make the MZ-372 simple and fast to operate and set up. There is even a master recording stereo output, which can send audio to an external recorder which makes event or music performance capturing easy. The Booth outputs provide another stereo feed with independent control for additional monitoring.

LD Systems zone 423 2-Zone-Mixer
The ZONE 423 is a full featured zone mixer with 4 line and 2 microphone channels, that can be assigned to a master and a zone output, as well as inputs for an external emergency announcement system and remote-controlled switching mute. Through versatile connectivity, the compact 2U rack device is the perfect control centre for PA systems in food outlets, clubs, hotels, fitness centres, and is also excellent for presentations and DJs.
In addition to the two balanced microphone inputs with variable Gain and Talkover level,12V-phantom power, and a shared 3-Band-EQ, the ZONE 423 offers Line, Phono-, and Aux-stereo connections in RCA format, a FOH-input with balanced stereo jack plugs as well as a USB and 3.5mm mini jack. The USB-port is used as a stereo input and output and allows the mixer to be used as an external audio interface. The four input channels have individual gain controls with signal and peak value display, 45 mm faders for adjusting the volume and cue buttons.
The master and zone sections each have their own EQ, balanced XLR and unbalanced RCA outputs: the master output via terminal block connectors and the zone output using a mono sum switch, and 100 Hz high-pass filter. The stereo level indication can be set to master or zone, and the maximum output level can be preset for both on the back of the mixer. In addition to an adjustable headphone connection for pre-listening, the ZONE 423 also has a recording output.

LD Systems ZONE 622 2-Zone Mixer
The ZONE 622 is a particularly compact 1U zone mixer with 6 line and 2 microphone channels, that can be assigned to a stereo or a mono master output. The device has all the essential functions, an input for an external emergency announcement system with its own volume control, and a connection to the remote-controlled switching mute. The ZONE 622 is suitable as a sound system for separate zones in restaurants, clubs, hotels, fitness centres, and for presentations.
The two balanced microphone channels with stereo jack inputs are equipped with controls for Gain, Talkover volume, Talkover attenuation, 12V phantom power and a shared 2-band EQ. The line channels 1 and 2 can also be used to connect unbalanced microphones, and channel 6 is specially designed for balanced FOH signals. The stereo input channels of the ZONE 622 have a Cue button and volume control signal display, and the channels 1-5 have an additional gain trimmer. Furthermore, the zone mixer has a 3.5 mm mini jack input and a USB port , that is used as a Stereo Input and Output (Recording Out). So you can use the ZONE 622 as an external audio interface.
The stereo and mono output sections have their own meters, 2-band EQ, trimmer for adjusting the maximum output level, as well as electronically balanced jack plugs and terminal block connectors. In addition, the stereo section has unbalanced RCA jacks. An adjustable headphone jack for previewing and a recording output complete the equipment for the ZONE 622.
