LAB GRUPPEN POWER AMPLIFIERS - LUCIA - 70V, 100V
This range of single-channel amplifiers have been designed for applications in retail, education, restaurant and office environments, powering 70V or 100V speaker lines. The compact half-rack, 1U amplifiers can be installed near to the audio source, such as lectern, projector or reception counter, as opposed to a remote systems room. Wall-mounting is possible with the supplied wall-mount bracket; optional pole-mounting and rack-mounting kits are also available.
These LUCIA - Localised Utility Intelligent Amplification - amplifiers have differing power outputs; all are compliant to Energy Star efficiency guidelines. They have of two inputs which are mixed down to a mono signal, to feed the single channel output. All have the same automatic standby mode as the LUCIA low impedance amplifiers (see Lab Gruppen Power Amplifiers - LUCIA - Low impedance for further details), where the unit is set to standby mode if no audio input signal is sensed for a period of 20 minutes, thus consuming less than 1 watt.
All inputs and outputs are detachable screw terminal blocks, positioned on the rear panel, other than the alternative inputs on unbalanced RCA (phono) connections. The 2 to 1 mix can be remotely adjusted by way of software on a connected PC or Mac. This also gives access to DSP functionality such as 'Automatic Dynamic Loudness Contouring', and pre/post-mixer EQ filtering, including up to four EQ sections per input and four EQ sections for the output. EQ presets can be recalled to match many compatible loudspeakers. The PC or Max OSX software has a 'wizard' setup function for fast adjustment; an advanced setting allows offline configuration that can later be downloaded to the amplifier at a later time. Both are transferred to one or multiple amplifiers via USB. The same USB connection can be used to update firmware. Rotary level adjustment controls are positioned on the front panel of the amplifier, with LEDs to signify the signal and limiting status. A third LED shows the standby mode or fault status.
LUCIA amplifiers can also be controlled and/or monitored by way of GPIO connections or the RS232 interface along with optional third party hardware/software. Amplifier volume control can be remotely adjusted by the optional LUCIA Wall panel level control unit or 'Lab.Level' remote volume controller for desk or table top.
All models: Nominal voltage: 100-240V AC. Operation voltage: 85-265V AC. Standby consumption: Less than 1W. Dimensions: 216 x 44 x 280 (w x h x d) mm.
