| Content | LD Systems ZONE 624 4-Zone Mixer
The ZONE 624 is a fully-equipped zone mixer with 6 line and 2 microphone channels, that can be assigned to a stereo or a mono master output. The compact 3U rack device also has inputs for an external emergency announcement system and remote-controlled switching mute. Due to its extensive connectivity the ZONE 624 is the extremely flexible control centre solution for PA systems in food outlets, clubs, hotels, fitness centres, and many other areas.
The two balanced microphone inputs have a shared 3-band EQ, 12V phantom power and Talkover functions; the Talkover attenuation can be individually set for all zone outputs on the back of the unit. The 6 stereo input channels of the ZONE 624 are equipped with gain control, signal and peak LEDs, 45 mm faders, Cue buttons and RCA connections; channel 6, in addition with balanced TRS inputs for FOH signals. The device also has a switchable Aux input via 3.5mm mini jack and a USB port, that is used as a stereo input and output (recording out) and turns the ZONE 624 into an external audio interface.
The master section outputs are electronically balanced and use XLR connectors and terminal block connectors. The stereo zone also has unbalanced RCA connectors. The maximum output level for all of the zones can be individually set. The three mono outputs of the ZONE 624 each have a 2-band EQ, a selectable 100 Hz high pass filter, and a MIC mute switch with a level indicator; the inputs 1-6 or the stereo master signal can be selected as a source. The stereo output is equipped with a 3-band EQ, a control for the Talkover sensitivity and two LED chain level meters. Furthermore, the ZONE 624 has a recording output and a controllable PFL headphone jack for previewing.

| The MZ-223 allows multiple audio sources to be mixed, segregated, and routed to 3 independent zones or destinations using familiar volume sliders and assignment buttons. Input signals can be inserted via 5 audio channels, each consisting of 2 sets of unbalanced RCA stereo pairs. A total of 10 sets of RCA inputs are provided. Channels 1 and 2 can be set to accommodate phono-level signals for use with a turntable. In addition located conveniently on the front panel, 2 mic-compatible
The independent 3-zone outputs each have a combination of balanced professional XLR or RCA unbalanced configurations for long runs or connection to common residential power amplifiers or speakers. This flexibility, for example, allows music to be routed to ZONE1, ambient noise or natural sounds to ZONE2, a separate music track or a voice announcement can be routed to ZONE3, while the convenient "Talkover” function will automatically lower any mixed channel source so the microphone can be heard while speaking.
- Easy operation and routing via familiar volume sliders, toggle switches/buttons, and knobs
- 3 Independent Zone outputs with stereo XLR balanced and unbalanced RCA connectors per channel
- 5 separate input channels, each with two sets of stereo RCA inputs
- 2 additional mic-compatible XLR inputs on the front panel
- All audio can be mixed or segregated per channel, and routed to the 3 separate Zones/Outputs
- “Talkover” function automatically lowers other source content while microphones are in use
- Independent 3-band EQ per output channel and per microphone input
- Compact 2U rack mount design
