installationfeature Powersoft K Series amps were chosen for the Granada Theatre
analogue and AES3 inputs, and
Lab.gruppen limiters complete a core specification that is also resonating with install customers. LUCIA,
Lab.gruppen’s other
new range, was developed with install in mind from day one.
The line comprises four models across two power configurations – 2 x 60W and 2 x 120W – each available with either 4-in, 4-out matrix-mixer and configurable DSP features (LUCIA 120/2M, LUCIA 240/2M) or in a basic
2-in, 2-out configuration (LUCIA 120/2 and LUCIA 240/2). While all models are equipped with DSP pre-configured ‘out of the box’ for operation in typical applications, the Matrix variants also facilitate extensive set-up via USB connection. Running contrary to the install philosophy that sees audio control and power being brought into one rack room, LUCIA is instead “intended for decentralised systems, putting amplification, processing, matrixing and I/O exactly where it’s needed – close to the loudspeakers and the input devices (and the end user!). There are inherent benefits to this approach – when it happens to suit the application – in terms of better sound quality (low impedance so no transformers), no 70V/100V lines with trunking running from the rack room, and potentially saving money on the cost of transformers in the loudspeakers when there’s an option to buy Low-Z versions.”
“At a time when there is concern about energy costs, the market
welcomes the efficiency of Class D” Gerry Tschetter, QSC
Due to begin shipping in September, LUCIA is proving to be “probably the most positive product introduction we’ve seen in recent years – almost surprisingly so,” admits Flanagan. “We knew this would bring new potential to the market and engage our existing customer base, but it looks like it will do a whole lot more, attracting a new segment of the market.”
LIFE IN THE FAST LANE Several of the aforementioned strands – making Class D designs more efficient, and catering to the demands of live and install – are combined in QSC’s new CXD and PLD power amplifier
families. Introduced to no small fanfare at InfoComm in June, the ranges share a common four- channel Class D platform, but are separately geared towards fixed installation (CXD) and live sound reinforcement (PLD). Shipping as of last month, the two ranges both deliver powers ranging from 400W to 1,150W (at 8 ohms). A groundbreaking innovation
in power distribution is central to the undoubted industry excitement around these amps. Specifically, QSC has built in a new function, dubbed Flexible Amplifier Summing Technology (FAST), that actively distributes the total amplifier power in various combinations across one,
