Cyrus Audio
The company Cyrus Audio Ltd. is a British manufacturer of hi-fi equipment, which emerged in 2005 from the dissolution of Mission Cyrus . The company is based in Huntingdon .
Since the early 1980s, Cyrus was another brand name of Mission Electronics , which was founded on July 7, 1977 by Farad Azima, supported by his brother Henry Azima as a developer, and Stan Curtis. Loudspeakers were manufactured there under the name Mission , later also electronic components (preamplifier, power amplifier, integrated amplifier, turntable, tonearms, pickup systems, CD player and much more). In July 1984, products under the name Cyrus were presented for the first time , the HiFi amplifiers Cyrus One and Cyrus Two, followed by an additional PSX power supply and tuner in a “shoebox” housing design like the predecessor Mission Cambridge 778 integrated amplifier. Holden & Fisher toroidal transformers were used in the amplifier power supplies , "Fast" rectifier diodes and ELNA electrolytic capacitors with low internal resistance are used, which have been considered in the interplay with the amplifier circuit in the professional world. Later Cyrus I / II series devices in a cast housing were equipped with slit-foil electrolytic capacitors, whose low-eddy current delivery capability gave the amplifier even more brilliance. Denis Morecroft's ideas were incorporated here. The Mission 7000 CD player was followed in 1989 for the first time under the Cyrus logo by the PCMII CD player with a connection socket for the Cyrus PSX additional power supply, which primarily provided the Cyrus 2 with more power, but could also provide powerful power to the output stage of the PCM II. Based on a Philips CD player with a selected TDA1541 D / A converter, the PCM II had several other special features: The stable, non-magnetic additional base plate reduced device vibration, the audiophile filter and output driver stage with remote-controlled volume and low output resistance also offered for the first time via FB Pressing a button, the polarity correction option (the absolute polarity of many CDs is "inverse") and an external terminating resistor on the digital output reduces the effects of the output transformer on the electronics. When speaking of the interplay between Mission loudspeakers and Cyrus Electronics, this applies particularly to the Mission 767 loudspeaker model, with a 25 mm tweeter in the middle with a fabric dome and waveguide, above / below each symmetrical 17 cm woofer with additional support 20 cm woofer, which were controlled separately by a Cyrus LFAU (Low Frequency Adjustment Unit). LFAU was built on the basis of the Cyrus II, but instead of the phono section there was an equalizer, adjustable lower cut-off frequency, variable overlap with the bass-midrange speakers and level controls gave options for taste and room adaptation. There is a noticeable accumulation of the number 7 in the naming of all Mission products, with only a few exceptions (such as with Isoplat or Rose cartridges). From the date of foundation to the license plate number, the 7 is included. With Cyrus this is limited to the models DAD7, FM7 (7.5), Cyrus7.
A big fire in the spare parts storage area, which also destroyed many technical documents, and losses in the mission computer area interrupted the economic success up to then and outside capital brought outside influence. The combination of the Mission DAD5 OEM CD player based on a Philips (similar to CD-115) with an optional D / A converter DAC 5 made it possible to expect a departure from the introduced line due to the completely different housing design, and there was also a midi Hi-fi system under the Mission logo at that time, an indication of the influence of a financial holding that also belonged to Sansui. The Mission 761 loudspeaker was available in parallel with the Sansui label Made in Huntingdon .
The Azima brothers regained the upper hand with a holding Verity Group and the new beginning brought the Cyrus III integrated amplifier with remote control, Cyrus Discmaster and Dacmaster (top-loading CD drive with Philips CDM9 Pro and separate D / A converter) with a softened form of the standard housing. , followed later by Pre and Power (preamplifier and power amplifier), a universal PSX-R power supply unit, which adapts to the voltage requirements of the components to be supported through communication, and DAD7 (top loader integrated CD player with CDM9), FM7 tuner. All devices were to be connected to the MC bus, which combined device communication with the individual remote control of the individual devices, as well as with the system remote control Commander with the rotary knob for the volume. It was evident that a joint development team for loudspeakers and electronics was not meeting the requirements of the time; many ideas awaited execution and Cyrus moved to new premises, a separate area in the Verity Group. Products were surround decoders (AV master), multiroom (MR3), the Cyrus 3i, whose AUX input in connection with AV master and MC bus communication equated the amplification factor of a stereo power amplifier, which is a simple fusion of stereo operation and multi-channel without the CD player signal having to pass through the surround decoder. The 3rd generation of the additional power supply PSX-R is available today. It is reserved for the more complex devices, where the front-end is supplied in the best possible way, e.g. B. the preamplifier section in the integrated amplifier, the voltage amplification stage in the output stage, while the following part is supplied from the internal power supply. This clearly distinguishes the PSX-R from the first PSX, which supplied the power amplifier in the Cyrus II externally and increased its output power. Cyrus devices are known today for their format with a width of 215 mm, which can be described as a half-size design compared to the widespread 430 mm format or the 483 mm (19 ") format from the professional sector.
