| Content | The MA125 is a very compact, professional PA mixing amplifier for commercial and industrial applications. The MA125 can drive 8 Ohm or constant voltage loudspeakers. The MA125 has 4 microphone inputs with integrated speech filters, 4 selectable line inputs and one emergency line / telephone input. MIC input 1 is meant to be the main microphone paging input. Its signal can be fed via the front jack or via the XLR3, DIN5 or Euroblock connector at the back. When needed, two APart paging microphones (MIC-PAT-D) can be wired in parallel on each microphone input.
The MA125 has a 3-level priority system. The emergency line / telephone input at the back has the highest priority. MIC1 has the second priority level and the third priority level can be activated by a dry contact at the back of the amplifier. This dry contact mutes all background music inputs. It also activates the integrated chime. The level of the chime can be adjusted at the back of the amplifier. Activation of the dry contact, releases a 24V output power? this can be used to switch the relays of loudspeaker attenuators or other devices. When needed the signals mixed via your MA125 mixing amplifier can be recorded or distributed via the record output. Further the MA125 is supplied with detachable 19” brackets.
The MA125 is the device to built professional industrial applications. You can insert an extra EQ (such as the APart PXQ2215) into the signal path or add extra power amps (e.g. PA240P), using the pre-amp out / power amp in RCA connectors. | User's manual [5,41 MB]
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.

| 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.
