Studiomaster’s new HX and QX digital power amplifier series exploit the compact form factor and weight-saving, and operational appeal of the latest class-D technology, claiming ‘new levels of power and performance, at highly competitive professional entry market (HX series) and premium market (QX series) price points’.
The ultra lightweight and compact 1U-high HX series meet a range of professional audio requirements, including commercial installation, conferencing, small- and medium-scale sound reinforcement, and rental applications. Features include high efficiency power factor correction (PFC)
, Thermal, Overload and DC protection, protection and Status indicators, output limiter, universal 90-250VAC power supply, multiple gain modes, variable speed fan cooling, balanced XLR inputs and professional speaker connectors.
Two-channel and 4-channel models with stereo/parallel/bridge mode operation, provide reliable and efficient operation at 2Ω loads, No less than eight models in the range include four 2-channel models, rated at 300W, 500W, 700W and 900W (at 8Ω), and four 4-channel models rated at 600W, 1kW, 1.4kW and 1.8kW (at 8Ω).
The QX series is intended for large to very large-scale, high-end sound reinforcement, installation and rental applications. Featuring advanced amplifier adjustment technology to provide over 95 per cent efficiency, and stable performance under high current, low impedance (2Ω) conditions. Features include active power factor correction (PFC) and a soft power switching power supply, which operates universally between 90-250V AC, as well as a 32A mains power input socket, Thermal, Overload and DC protection circuitry, Thermal, Overload, DC and Status indicators, multiple gain modes, balanced XLR inputs, output limiter and variable speed fan cooling.
The 1U-high lightweight design weighs-in at less than 12kg. Two-channel and 4-channel versions of the amplifiers, with stereo/parallel/bridge mode operation, offer power ratings ranging from 2.55kW/channel up to 5.1kW/channel at 4Ω. At 2Ω operation, the top-of-the range QX4-8000 will deliver up to 4 x 5.78kW. The QX series comprises three 2-channel models rated at 3kW, 4kW and 6kW and two 4-channel models rated at 6kW and 8kW (all at 8Ω).
‘With the HX /QX amplifiers, no installation or PA hire company, no matter how small or price competitive, need settle for inefficient, underpowered poor quality amplification,’ says General Manager Patrick Almond. ‘We have come relatively late to market with digital product offerings but we have spent considerable development time, both in configuring these products precisely for specific applications and market sectors, and in exploiting latest processing technologies when they become available at a price point that allows us to offer these extended specifications, features and operational capabilities, previously unavailable to more budget sensitive market sectors.’
