  • Jadis JA80 single mono amplifier

    Jadis JA80 single mono amplifier

    Jadis JA80 single mono amplifier The JA80 is a power amplifier working in pure class A. It is the first amplifier created by the JADIS in 1983; it has been upgraded several times but remains the flagship of the brand. It works in a "push-pull" configuration with triple load and autobias. It can work with various types of penthodes: KT120, KT90, KT88, 6550, 6CA7 or EL34. The function phase shifter is insured by a triode double ECC82 and the function driver by an ECC83. The output transformer, guaranteed for life, allows an adaptation of impedance from 1 to 16 ohms. The cathode circuit is protected by an individual fuse. The power transformer is oversized for a better dissipation of heat and vibrations. The filtering of the high voltages is assured by high capacity capacitors. Heating the tubes is by alternate current with balance and noise reduction. Output terminals allow a bi-wiring. Gold connections assure a faithful broadcast of the signals. The device is assembled with conventional cabling "point by point" and uses a silver / copper tin solder. The frame, in 316L non-magnetic stainless steel, does not influence the electronics and renders the device unsensitive to external disturbances. Learn More

The parallel-mono mode shall parallel the outputs to provide increased output current. The output impedance of each channel shall be less than 10 milliohms in series with less than 2 microhenries in stereo mode. The variable impedance power supplies shall reduce unnecessary voltage across the output devices by automatically switching to a parallel mode when less voltage is required by the output circuitry and to a series mode when more voltage is required. The amplifier shall contain protection circuitry which limits the drive level placed on the output devices before their SOA (Safe Operating Area) is exceeded. This protection circuitry shall calculate the instantaneous voltage across and current through the output devices while factoring in their simulated junction temperatures to predict how close they are to their operating limits. This protection will be called “ODEP.” The amplifier shall contain controlled slew-rate voltage circuitry to protect it against radio frequency interference burnouts. It shall also be protected from current overload at its output stage. The slew rate of the amplifier shall be greater than 30 volts per microsecond in stereo mode. The amplifier shall temporarily go into a stand-by mode if its power transformer becomes excessively hot and shall automatically resume normal operation once it has cooled to a safe operating temperature. Front-panel controls shall include an enable on/off switch and a detented input level control for each channel. Rear-mounted controls shall include a ground lift switch to isolate the signal ground from the chassis ground, a switch which selects between stereo, bridged-mono and parallel-mono modes of operation and a reset switch for the AC mains circuit breaker. Internal controls shall include an input sensitivity switch to select between 0.775 V, 1.4 V or a fixed voltage gain of 26 dB for full rated output. A Crown P.I.P. and P.I.P.2-compatible expansion connector shall be provided behind an access panel in the rear to accept auxiliary input modules. It shall be fully compatible with the Crown IQ System. Front panel indicators shall include an amber power enable indicator, an amber ODEP protection system indicator for each channel which shall normally be illuminated to confirm the availability of reserve thermodynamic energy and which shall dim in proportion to limiting when the power demands of the output stages have been exceeded, a green IOC indicator for each channel, and a green Signal indicator for each channel which shall normally flash at moderate intensity to show the presence of an audio signal. The power amplifier shall meet or exceed the following performance criteria. Input sensitivity for rated output: 26 dB voltage gain (unbalanced).

    Classe Audio CA5200 5 channel power amplifier

    Listed conservatively at 200 watts per channel times five channels, the Classe Audio CA-5200 is what we could call a beast of an amplifier. It mainly operates as a traditional class AB amp but, at lower outputs, the Classe' engineers have figured out a way to make the amps run as a class-A amp (no pun intended), which reportedly reduces some of the noise associated with class AB switching, not that you can hear any audible noise when auditioning the Classe' CA-5200, as this power amp runs very, very quietly. The Toroidal transformer (the heart and soul of any good class AB amp) is custom-made and extra-beefy, yet the Classe' CA-5200 runs cool as a cucumber. Learn More

  • Linn AV 5105 Stereo Power Amplifier

    Linn AV 5105 Stereo Power Amplifier

    Linn AV 5105 Stereo Power Amplifier The Linn AV 5105 Stereo Power Amplifier is intended for use in high performance audio and audio/video systems. It combines high output power, ruggedness, and ease of use with our passion for quality. It draws on years of experience of designing and making high quality audio power amplifiers. Inside the compact case are two completely independent electrically isolated channels with fully regulated power supplies giving ‘dual mono’ performance. The signal path is DC coupled and servo controlled for the lowest distortion, cleanest, least colored sound. The output stage is highly derated for cool, reliable operation, and the protection circuitry protects extensively against accidents or abuse. A signal sensing circuit detects the presence of audio above a very low level and turns on the main power supplies to the amplifier, bringing the power amplifier channel from a very low standby power consumption to full operation. It reverts to the standby condition a few minutes after the input signal disappears. This is particularly useful in multi-channel surround sound systems. The AV 5105 accepts the Linn active crossover modules, automatically detecting their presence and switching them in circuit as soon as they are plugged in. This makes playback system upgrades easy. Type Two fully independent channels, isolated from each other and chassis (earth). Fully regulated dual power supplies per channel. Inputs Dual RCA Phono (Line in/out) Outputs Four pairs per channel Protection Fully protected into any load; overload, over-temperature, full short and overdrive protection Remote control Signal-sensing auto switch-on/off for energy conservation or remote operation Output power 100W/channel/8Ω, 200W/Channel/4Ω Input signal 1.05V rms for maximum output Output voltage 28.3V rms maximum Gain x27 (28.6dB) Input impedance 4700Ω Frequency response (-3dB) 2Hz-50kHz Output offset 150μV rms Mains supply 220V–240V T3.15A antisurge, 100V–120V T6.3A antisurge Standby power consumption Learn More

  • Thule Audio PA100 power amplifier

    Thule Audio PA100 power amplifier

    Thule Audio PA100 power amplifier Thule Audio is a Danish company, specializing in audio equipment, ranging from basic entry level models, to models which are High End stuff. The product line is well thought out, and as we shall see, very rationally conceived and executed. For other reviews of Thule Audio products, look over the site. Both cases are virtually identical, and share the overall look of the entire Thule Spirit range. They are made of uncommonly thick, heavy and well finished cases, while front panels are made from 8mm thick aluminium, machined so that they have a gentle slope. In the center, one will find a "gold" knob in case of the preamp, and a decoration in case of the amp. The preamp has an alphanumeric display above the knob, which provides the user with all relevant information on power on, volume and input status in red LEDs. All this is fully remote controllable, and a remote control unit is supplied. The power amp is a very simple affair, with only a red LED power on indicator on its front side. Both units have rocker power on/off switches at the back, as they're intended to be left in standby mode all the time. [Thule PR 100 inside view] Both units share much more common componentry that I would have imagined. Both use toroidal power supplies, where the amp's toroid is rated at 500VA, while the preamp's toroid is rated at 300VA. No, you're not seeing things, it's not a typo error, I did say 300VA. That's enough for a 2x75W/8 Ohm power amplifier, let alone a simple preamp. In fact, the preamp is EXACTLY the same as the IA60 integrated amplifier, minus the power amp circuitry and heat sinks. Put another way, the preamp consists of the preamp section of the IA60 integrated. Hence the 300VA toroidal transformer - that's what they use in IA60 (see review on this site). The power amp, on the other hand, is once more the same board, but minus the preamp circuitry and with heftier power supplies - bigger transformer, and 4x10.000uF capacitors, instead of just 2x10.000uF. This is no accident, this is rational thinking. Use the same board, use the same case, use the same power supplies and you increase the numbers of your serial production, thus pushing the cost per unit down. The only thing that spoils the show is the preamp's price - it's simpler than the integrated model, but it's not only not cheaper, it's actually somewhat more expensive. That is most odd, I must say - probably for "complex marketing reasons" (a phrase I first heard in the early seventies, and it's gotten worse since then). You still have 5 line level inputs, with no option for a phono RIAA board of any kind. You still don't have a headphone output - somebody should inform the Scandinavian audio industry that headphones have been invented some decades ago, they seem to have collectively overslept that event. As usual, all input and output sockets are gold plated. Like elsewhere in Thule's product portfolio, volume and balance are controlled by a ladder of laser trimmed resistors, contained within an LM1792 digital volume control, a good point - no mechanics, no wear and tear, no aging, unparalleled precision. The amp is rated at 2x100W/8 ohms and 170W/4 Ohms - that should be enough for most of us. It has an RCA Cinch and a balanced XLR input, just as the preamp has the same outputs. Acting on logic and Thule's recommendation, I used balanced lines to link the two, except when using other units. Learn More
