| Content | With the MA200 mixing amplifier series, the APart engineering team has created some unique, original and above all, complete electronics. Never before has a mixer amplifier had all the features to meet a contractors demand for nearly every application.
- The most important features:
- 200 watt 100 Volt mixing amplifier
- 4 mic inputs (phantom via internal switch)
- Mic inputs have integrated speech filters and are high-class transistor balanced
- 4 Line inputs
- 4 Loudspeaker output zones can be selected (switch on/off) and have LED indication. Zone 4: selection of "Music only”, "microphone only” or both music and microphone.
- Bass-treble tone control
- Master volume control
- 3-Level priority system:
- 1. Emergency input: directly to the power amplifier (vol adjustable)
- 2. VOX Mute: Voice activated mute (adjustable) on MIC input 1 mutes all other inputs
- 3. Contact closure mutes all line inputs
- LED indication on front pannel when line inputs are muted
- 24V ouput power is activated via contact closure. Can be used to switch the 24V priority
- relays of volume controls.
- Integrated 2-tone chime has an adjustable volume and is activated by contact closure
- Build-in dynamic limiter (-3dB)
- Record output via RCA
- PRE AMP OUT - AMP IN makes it possible to insert an external signal processor or to add
| 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
| 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.

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.

| REVAMP1680 is a professional 16-channel digital power amplifier with 16 x 80 watts output power @ 4 ohms, but the unit is also bridgeable to 8 x 160 watts @ 8 ohms. This 3 rack units high amplifier with very high channel separation also has a dual analog power supply with toroidal power transformers. The standby power consumption is very low, less than 0.5 watts!
Another smart feature of the REVAMP1680 is the switching mode standby power supply with multiple auto power on/off options. You can power on or power off the unit via a trigger input, audio sense... The trigger input is ideal when you want to switch on the power amplifier automatically using an external AC or DC trigger signal coming from your audio system. The amplifier will be switched on as long as the trigger voltage is present. Alternatively, you can set the power on mode switch to the audio trig position: the amp will automatically switch on when a sufficiently strong audio signal is present at the input and automatically switch off after a few minutes of silence.
This amplifier is equipped with 2 stereo bus inputs with pass through. These bus inputs are ideal when you want to hear the same audio signal in different output zones with the advantages you need less audio cables and the installation can be done very fast.
With its very low standby consumption and the fact the amplifier can easily be integrated in any audio project, the REVAMP1680 will soon become your favourite multi channel power amplifier. |
