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 Compact 9.2 1U installation mixer is built to combine maximum audio possibilities and needs for a pub, school, or public area without scarifying on the ease of use. The user can adjust 3 microphone levels and 2 line levels. Both line levels have 6 selectable input sources which are shown on a clear display. On each line input it is possible to select a pre-programmed label which is shown on the display, so there is no need to do difficult programing. This will help users to select the desired source for the desired area, because the Compact 9.2 also has 2 individual zones. All gain, EQ, phantom power and technical settings are on the backside. Once the installer has set everything correctly the user doesn't need to worry about difficult settings, only volume and source select are available on the front panel. The front panel also has a special input if you like to connect a device instantly. This input can be switched between line and phone mode. The phone mode adjusts the input sensitivity into the correct value for MP3 players, smartphones or tablets. Now you can playback your MP3 devices directly without signal loss. The Compact 9.2 is the perfect solution for situations where non-technical users need to operate professional audio systems.

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.
