Power Amplifier

Power Amplifier From the transformer to the input terminals, each section of the Artera has been engineered from the ground up to ensure power, musicality and stability. The Artera Stereo produces 140 Watts RMS per channel – ample power for driving first-class loudspeakers, unfaltering even under high dynamic and transient conditions thanks to the patented Current Dumping technology. Special attention has also been paid to the newly developed balanced XLR inputs. The robust connections are yet another string to the Artera Stereo’s bow, with an incomparable signal to noise ratio.

Power Amplifier Designed by Tim DeParavicini, the QUAD II-Eighty takes inspiration from the original QUAD II amplifier. It is an 80-Watt mono power amplifier following in the tradition and philosophies of Peter Walker. The output section consists of 4 KT88 valves running as two pairs in push-pull with the hallmark QUAD topology of partial cathode loading in the output transformer.

The QUAD II-forty power amplifier is much more than a tribute to one of the most famous designs in audio – but refined and powerful in the modern sense of the terms. Although the circuit topology has changed a little from the original, significantly better components and a brand new transformer design have been engineered. While still being delicately balanced a fast, crisp and detailed sound is achieved, whilst producing an output current suitable for modern loudspeakers, including our very own ESL. KT-88 output valves work in a push-pull configuration, while a choice of 4 Ohm or 8 Ohm taps allows for a wide choice of loudspeaker configurations.

The Rockville DS10 delivers true 1000W RMS power, making it a powerhouse for professional DJs, live sound applications, and home audio setups. This lightweight Class-D amplifier is designed for high efficiency, offering 2 x 500W RMS at 4 ohms and 2 x 300W RMS at 8 ohms, ensuring clean, consistent power output without distortion or overheating. You can also bridge the amp to get 1000w RMS x 1 @ 8 ohms.At just 6.6 lbs and taking up only 1U of rack space, the DS10 is slim, portable, and incredibly easy to integrate into your setup. Whether you're powering PA speakers, subwoofers, or monitor systems, this amp gives you flexibility and control with a built-in crossover switch (full-range, 110Hz LPF, 110Hz HPF) to optimize your sound.Equipped with XLR inputs and Speakon outputs, the DS10 ensures reliable connectivity, while front-panel LED meters provide precise volume monitoring in dB per channel. Safety is built in with short circuit, thermal overload, and DC overload protection, plus a built-in limiter to protect your speakers from distortion and clipping.Power Ratings:RMS Power Output: Stereo 4 Ohm: 2 x 500W Stereo 8 Ohm: 2 x 300W Bridged 8 Ohm: 1 x 1000w Peak Power Output: Stereo 4 Ohm: 2 x 2000W Stereo 8 Ohm: 2 x 1200W Bridged 8 Ohm: 1 x 4000w Terminals:Input Terminals:XLR Ch1 & Ch2 inputsOutput Terminals:Speakon outputs Ch1 & Ch2Features: Rockville DS10 1000w RMS Class D 2 Channel Power Amplifier Pro/DJ Amp 1U rack space and only 6.6 Lbs Built in crossover switch (full range, 110 LPF Hz, 110 HPF Hz) allows amp to be used with full range PA speakers, or Subwoofer(s) Front Panel displays volume in dB per channel via LEDS Built in limiter protects your speakers from distortion and clipping Power, signal, limit, and fault LED indicators on front of amp Speaker short circuit, thermal over load, DC over load Built-in variable speed quiet cooling fans Stereo mode is perfect for (2) speakers or (4) speakers in a left and right configuration Parallel mode gives you dual mono output signal which is perfect for monitor use when you want all sounds coming out of each speaker instead of a left/right configuration Channel 1 & 2 Limiting Led Indicators Channel 1 & 2 Separate Level Controls Heavy duty rack mount ears and removable feet give you multiple options Level controls for precise setting and matching of sensitivity Can power (2) or (4) 8-ohm speakers, (2) 4-ohm speakers (4) or (8) 16-ohm speakers User serviceable fuse (10A, 250V) Frequency Response:10 Hz – 40 Khz at +/-3dB Input Impedance: 10K Ohm Balanced Input signal sensitivity: 540mV – 2.5V Stereo Separation (Crosstalk) : -57.7dB at 5kHz Damping factor: ( 100Hz, 10w, 4 ohms): 165 Output impedance at speaker terminals: 0.0836 Ohms THD+N vs Frequency <0.07% at 1 Watt RMS 20Hz-20kHz Signal-to-Noise: 90 dBA max output SLEW RATE (input filter limited) : 29v/uS Power Requirements: 110V / 50-60Hz Dimensions: 19” x 10.24” x 1.97” Key Features: True 1000W RMS Power: 2 x 500W @ 4Ω / 2 x 300W @ 8Ω / 1 x 1000w @ 8Ω bridged Slim & Lightweight: Only 6.6 lbs and 1U rack-mountable Versatile Crossover: Choose Full Range, 110Hz LPF, or 110Hz HPF Smart Protection: Built-in limiter, thermal, DC Overload & short circuit protection Quiet Cooling: Variable Speed low-noise fans prevent overheating (speed increases as temperature increases) Pro Connectivity: XLR inputs & Speakon outputs for secure connections Stereo & Parallel Modes: Use for two speakers, four speakers, or monitors With high efficiency, rock-solid reliability, and unmatched power for the price, the Rockville DS10 is the perfect amplifier for DJs, bands, event venues, and pro audio setups.
