No racks required with Lab.gruppen’s Lucia
Optimised for use in small-scale A/V applications where high quality audio is required, Lab.gruppen’s Lucia series of low-impedance amplifiers has been expanded with two dedicated, 70V output models. Housed in a half-rack 1U chassis, the new models’ small form factor is intended for projects where there is no convenient equipment rack nearby.
With power ratings of 120W and 240W respectively, delivered to a single output, the Lucia 120/1-70 and Lucia 240/1-70 both incorporate dual inputs that allow the mixing of two sources or selection of either A or B sources for the single mono output. Connectors include balanced Phoenix type and unbalanced RCA for each input, with a built-in matrix function mixing the balanced and unbalanced signals. Front panel controls mix or select the A and B discrete source signals.
According to the manufacturer, the new 70V models couple a digital, firmware-controlled front end – including a multiband compressor and look-ahead limiter – to a patented Class-D output stage designed for ‘high efficiency, low distortion and minimal heat dissipation’. The units are equipped with a universal power supply, while intelligent fan control helps to limit unwanted noise. To save energy, the amps will automatically enter standby mode after 20 minutes of no signal input and then power up within one second when signal returns.
Alongside the two new models, the manufacturer has released a new version of the Application Browser software to support all six Lucia amps. With the updated software, all Lucia models will reportedly have the features previously only available on the Lucia M amplifiers, including custom EQ on each input, an adjustable matrix and output processing with selectable presets for loudspeakers or custom EQs. Automatic Dynamic Loudness Contouring can now be turned on or off per-output and configurable functionality for the two GPIs is available.
Finally, the manufacturer has unveiled v6.4 of its Lake Controller software, adding recallable EQ overlays to modules and groups. Also included is updated button placement for the Mesa EQ section and the Rational Power Management system.
