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.

| REVAMP4240T is a professional 4-channel digital power amplifier with 4 x 240 watt output power @ 100 volt, but the unit is also bridgeable to 2 x 480 watts @ 100 volt. The unit incorporates a high efficient SMPS power supply and outputs with efficient Class D output topology. REVAMP4240T is the ideal amplifier for applications with 4 zones in mono, 2 zones in stereo or even bridged dual mono or bridged stereo systems. This amplifier contains an intelligent variable speed cooling fan that only will be activated in case of emergency.
In order to match each input to its respective source the input sensitivity can be adapted to your needs. The input stage also features a build-in 250 Hz HP-filter to optimise the system for use on horn speakers whenever you would need this. Each pair of outputs can be bridged to give you 2 x 480 watts of output power! The very intuitive front display shows what is going on with one blink of an eye. The output power is constantly under control thanks to our own made limiter that prevents annoying pumping limiter sound but yet keeps the system fully under control and you still have that dynamic sound. Ease of use, high-tech, reliability and a wide versatility has never been as cleverly combined as in this REVAMP4240T amplifier. | 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 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.

| 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. |
