Amplificateur Pioneer SA 9500 SERVICED. All defective caps have been replaced and two relays also. Pioneer believes in music. And if you do, too, you'll find a faithful friend in the new SA-9500; one of the most musically minded pre/main stereo amplifiers we've engineered. It combines massive stereo output power with a delicacy of transparency; a rare blend in these days of lots of power at any cost. In other words, we haven't simply beefed up the power section at the expense of the tonal quality, frequency response or other aspects so important to the sound of a high fidelity component. The Pioneer SA-9500 does deliver an unusually large continuous power output of 80 watts per channel, min RMS at 8 ohms from 20 Hertz to 20,000 Hertz with no more than 0.1% total harmonic distortion, but it also ensures that even when operated at low volumes the performance retains a crisp, sparkling clarity. The dynamic response and reliability of the SA-9500 are matched with a flexibility of use you'll rarely find in this price range. Tone control versatility, for instance: both the bass and treble sections have 3-position turnover selection and there's a tone on/off switch for "flat" response at a touch. The 2-step high and low filters, the extra convenient tape duplicating switching system, multiple input source selection, 2-system speaker switching and much more mean first-class handling. We believe in music. And we're sure that if you do, too, you'll believe in the all-new SA-9500. Specifications Power output: 80 watts per channel into 8Ω (stereo) Frequency response: 7Hz to 40kHz Total harmonic distortion: 0.005% Damping factor: 30 Input sensitivity: 6mV (mic), 2.5mV (MM), 150mV (line) Signal to noise ratio: 65dB (mic), 70dB (MM), 90dB (line) Output: 150mV (line), 2V (Pre out) Semiconductors: 2 x FET, 54 x transistors, 26 x diodes Dimensions: 420 x 165 x 403mm Weight: 17.2kg Accessories: connecting cord, hex wrench, jack covers Year: 1976

SENNHEISER PXC 450 HEADPHONES - REDUCED TO CLEAR The PXC 450 is a circumaural high-end travel headphone set with NoiseGard™ 2.0 technology and TalkThrough function for the best possible attenuation of ambient noise. The PXC 450 enables an unprecedented sound experience for people on the move, thanks to its adaptive baffle damping in combination with the patented Duofol diaphragms, which prevent unwanted partial oscillation and thus guarantee a highly natural, lifelike sound quality. NoiseGard™ is an active noise compensation system which Sennheiser originally developed for use by pilots, who have to rely on good sound quality and efficient protection against ambient noise even in high-noise environments. NoiseGard™ actively compensates the noise, based on the physics principle of sound and counter-sound. NoiseGard™ 2.0 has perfected the NoiseGard™ principle thanks to the use of optimised circuitry design and even more efficient processors. It also uses better quality microphones, which enable more sophisticated pick-up of unwanted noise. Specially developed filter algorithms enable improved active noise compensation of up to 90% (23 dB). It is of course also possible to use these headphones passively, i.e. without NoiseGard™ and without batteries.  Users of a PXC 450 who wish to communicate with their neighbours can do so without taking off the headphones: when the TalkThrough function is activated, professional quality microphones mounted on the outside of the headphones pick up all acoustic signals in the immediate vicinity. Unwanted background noise, such as the sound of the engines on a plane, is filtered out electronically to a great extent, so that only the neighbour’s voice is passed on through the headphones into the user’s ear in top audio quality. The PXC 450 is foldable and is supplied complete with practical transport case, 2 AAA batteries and audio adaptors (double mono and 6.3mm). Volume control integrated in the headphones and a single-sided detachable and replaceable cable ensure maximum convenience for the user. SPECIFICATIONS: Colour: Silver Wearing Style: Headband Impedance: 150/750 ohms Connector: 3.5mm right-angled Frequency Response: 8 - 2800 Hz Sound Pressure Level: 108 dB Total Harmonic Distortion: Ear Coupling: Circumaural Cable Length: 1.4m single-sided, replaceable Transducer Principle: Dynamic Weight: 240g Attenuation: Passive - 32 dB Operating Time: > 21h Battery Specification: 1 x AAA Battery NoiseGard Noise Compensation: Up to 23dB (NG 2.0) 

Mc2 Mc750 Power Amplifier. In very good condition Fans have been upgraded with noctuas which are way more silent compared to the originals Description: MC750 digitally controlled power amplifier represents the latest technology in control circuitry coupled to a no compromise high quality class AB power amplifier. There is no dynamic switching of theaudio or power rails (a very common method of achieving extra power at the expense of audio quality) thus ensuring optimum sonic performance. The digital control monitors the operating parameters and adjusts the amplifier to suit the conditions. Fan speed and supply rails are varied as required to keep the amplifier within its temperature limits. The levels are adjusted by specially selected, high performance, digitally controlled attenuators. Signal limiters are included, the attack and release times of which can be adjusted internally by the bit switches on the control PCB (printed circuit board). The amplifiers include full DC and short circuit protection which automatically re-connects when the fault is cleared. Specifications: Power output: 625 watts per channel into 8Ω (stereo), 2150W into 8Ω (mono) Frequency response: 20Hz to 20kHz Total harmonic distortion: 0.03% Damping factor: 400 Gain: 31 dB Input sensitivity: 1.5V Signal to noise ratio: 106dB Speaker load impedance: 2Ω (minimum) Dimensions: 480 x 88 x 410mm Weight: 18.5kg
