| Content | 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. |
The MZ-372 allows multiple audio sources (19 total) to be mixed, muted, and routed to 2 redundant outputs, controlled by familiar volume sliders and assignment buttons. Input signals can be inserted via 6 audio channels, each consisting of 2 sets of unbalanced RCA stereo pairs, and 6 XLR inputs for a total of 12 sets of RCA inputs and 6 XLR inputs. In addition, channels 2/3/4 can be set to accommodate phono-level signals for use with a turntable. Lastly, and located conveniently on the front panel, one additional XLR input is available driving a studio quality mic preamp and ducking circuit for easy voiceover and announcement work.
Multiple Zone Outputs
Twin outputs each feature a combination of balanced XLR or RCA unbalanced connectors for easy integration into virtually any audio system. This flexibility allows combinations of microphones, CD/DVD/Blu-ray players, instruments - or any other audio source - to be selected or muted, and sent simultaneously to the dual outputs, each with it’s own volume control. Finally, the convenient "Talkover” function will automatically lower any mixed channel source so the microphone connected to the front panel can easily be can be heard in whichever zones you choose.
Easy, Immediate Control
Familiar volume sliders, switches/buttons, EQ knobs, and mute buttons make the MZ-372 simple and fast to operate and set up. There is even a master recording stereo output, which can send audio to an external recorder which makes event or music performance capturing easy. The Booth outputs provide another stereo feed with independent control for additional monitoring.
- Maximum flexibility for audio routing, input selection, and multiple redundant output flow, perfect for integrator, musical instrument, and residential applications
- Multiple inputs include 12 sets of stereo RCA-type, 6 selectable mic/line XLR, and a dedicated front-panel XLR mic input; 19 total input "sets”
- Channel audio sources can easily be selected, muted, and contoured via simple volume sliders, toggle switches/buttons, and knobs
- Two redundant output channels each with stereo XLR balanced and unbalanced RCA-type connectors; each with separate volume control
- Separate stereo booth, recording, and headphone outputs each with independent control
- One additional mic-compatible XLR input on the front panel with "Talkover” function automatically lowering source audio
- Independent three-band EQ per each of the 5 channels and a two-band EQ on the additional front panel microphone input
- Compact 3U 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.
