Primare SPA-22 HD AV Amplifier
The Primare SPA22 is available in 3 versions the SPA22 Base Model, SPA22 HD and the SPA22 HD AV. All 3 Primare SPA22 models are built on the same principle and can the two lower models can be upgraded to the full specification of the Primare SPA22 HD AV. The Primare SPA22 Base Model carries all the same features as the SPA22 HD except its standard audio board and the Primare SPA22 HD AV features five HDMI inputs where as the Primare SPA22 HD just features three, dual HDMI monitor outputs and analogue & HDMI video up conversion to 1080p are all extra features of the Primare SPA22 HD AV
The Primare SPA22 is a 5x120W integrated A/V amplifier and digital controller and is the natural successor to the award-winning SPA21, which was recognised around the world for its ease of use and ‘hi-fi’ sound quality. As the first of a new generation of Primare home entertainment products however, the Primare SPA22 represents a considerable evolutionary advance in terms of design, performance, user flexibility and versatility.
The Primare SPA22’s comprehensively shielded heavy-duty steel chassis houses a newly developed modular design that allows for DSP, video and connections to be upgraded easily with proprietary Primare boards, incorporating thoroughly evaluated and optimised versions of the latest technologies and connectors. This makes the SPA22 an ideal surround and video processing platform for many years to come
In every instance Primare have taken special care to keep signal paths short and layouts uncomplicated. Together with high performance FFC-wiring, these techniques give the unit an extremely high performance and the highest possible signal-to-noise ratio. The finest audio grade semiconductors and capacitors have been used whenever possible. All parts that are known to interfere with each other are isolated by shielding, dedicated signal paths and power supplies.
Switch mode power electronics is an important technology for reducing energy consumption and also to meet the demands for more channels in smaller enclosures. Unfortunately Class D amplifiers and switch mode power supplies have a deserved reputation for poor audio quality. The reason is that it is very difficult to apply enough feedback to control high frequency distortion while retaining stability in the Class D circuit. The culprit is the demodulation filter on the output, which shifts the phase 180 degrees. At low frequencies where the phase margin is large the application of enormous amounts of feedback creates fantastic THD figures, but at higher frequencies THD rises quickly. While the sound quality of such an amplifier is usually very dynamic and vivid, it can sound tiring and uncontrolled in the long run, especially when driving complex loads such as multi-way speakers. The worst examples have 0.001% THD at 1 kHz and 0.1% THD at 7 kHz: 100 times more THD at 7 kHz. Female voices can sound harsh and metallic, percussion like breaking glass.
Primare is now introducing a Class D technology called UFPD (Ultra Fast Power Device) which for the first time provides for the possibilities of an ‘audiophile’ Class D design. It is a Class D technology which has 30dB constant loop gain in the entire audio range and beyond the filter resonance frequency. It treats all signals equally regardless of frequency or slew rate and has the ability to suppress the filter resonance entirely
In conjunction with UFPD, Primare uses an isolated PFC (Power Factor Control) technology in the power supply, which controls the current from the mains voltage so that it is a pure sine wave with the same frequency and phase as the mains voltage. This means that even if 1000W is taken from the mains; other equipment in the room will not be affected. Its presence becomes virtually invisible to the mains voltage! The isolating stage of the converter works in a ZVS mode and as a result, the switch flanks contain a lower quantity of harmonics, providing lower EMI and a clean environment for the amplifiers to work in.
Almost every parameter in the configuration of the Primare SPA22 can be user defined. Any input can be assigned a name and associated with any audio and video source. Surround format, trigger activation and input sensitivity can be specified for the input. Individual levels, speaker types, crossover frequencies and delay configurations including bass management can be selected for each of the major surround formats. A 140mS global delay system, with dedicated DSP, is incorporated in order to achieve the best possible picture to sound synchronisation. For the highest possible installation flexibility, all the SPA22’s functions can be controlled in three ways: from the front panel, IR or RS232.
