| 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.

T.H.D.: | 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. | 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. | L1800 600W-600W 4ohm (360W-360W 8ohm)
