Sp4002 processing preamplifier

Tested, Sold as is in working condition Due to age a recap will be beneficial The SP4002 signal processing preamplifier is a very flexible preamplifier including two ten octave graphic equalizers, three way dubbing control for 3 tape recorders, two signal processing loops,, a subsonic filter and stereo/mono mode switching. The phono preamplifier design allows the use of two moving coil cartridges without head amplifiers and adjustable cartridge loading 50 to 800 picofarads (cf. picture). En savoir plus

I am selling my Aaron preamplifier because I have decided to upgrade to an integrated valve amplifier. The device is in excellent condition with no marks to note and i have used it in conjunction with my Meridian power amplifier to great affect. It comes with a solid aluminum remote control and manual. See the image for all input / output options. Unfortunately I don't have the original box but rest assured i will package the unit safely for transportation including a double box.   I bought it from a hifi enthusiast (like me) and critic in Montpellier about 2 years ago. He had it about 4 years before that. He told me he even preferred the Aaron to his Ayre preamplifier. This amplifier is still in production and can be purchased direct from Aaron (aaron-amplifiers (point) com) for € 3000. The cineast # 22 is designed as a home theater preamplifier, but it also performs amazingly in a 2 channel hi-fi setup. It is a pure analogue unit wth no digital processing involved. There is a good review on Hifiplus if you are looking for it.   It would be best to arrange delivery once we have a sale as i would recommend insured delivery with UPS.

    iFi Audio Micro iDSD DAC and Headphone Amp - with Pre amp Variable out. There is nothing like the micro iDSD. It is literally, out of this world. It is the only DAC in the world (at any price) to play True Native Octa-DSD512/PCM768/Double DXD. Its Perfect-Match means it can be fine-tuned to any headgear from IEMs all the way through to large headphones. Its 8v/4000mW output makes it one of the most powerful headamps to drive even the most hungry of headphones with ease. iFi has forged an enviable reputation for being at the forefront of computer audio technology. The micro iDSD has just made another leap, an Octa-Leap to be precise. With its special Dual-Core Burr-Brown native DSD/PCM chipset at the heart, the micro iDSD is capable of True Native PCM768, Octa-Speed DSD512 and 2x DXD; it is simply out of this world. The micro iDSD has 3 different power modes Eco, Normal and Turbo. Capable of 4000mW, 1000mW or 250mW, the micro iDSD is able to drive the full gamut of headphone and amplifiers alike. With iEMatch there to dial to suit any IEM, the micro iDSD has redefined the headphone amplifier class. Used along with the analogue volume control, the diminutive size of the micro iDSD belies its uncanny ability to drive virtually anything and everything! SmartPower® is the micro iDSD’s onboard recharging feature for Smartdevices. Its 4800mAH battery is able to fully recharge an iPhone two-times. Compatible with Apple and Android, phones and tablets, it is another example of iFi’s commitment to customer needs – enjoy high-end audio on the go without worrying about the phone going flat. iFi’s iCAN and iTube have already achieved widespread acclaim, so much so that their core features including 3D Holographic and XBass have become renowned in their own right and imitated by others. In the micro iDSD, for the first time in an iFi product, it features XBass and 3D Holographic for Headphones and Speakers. All these features are still executed in the analogue, not digital domain to preserve the original music format. And so much more….with the amazing Crowd-Design program, we are over the moon that you, the customer was central to the development of the micro iDSD. The micro iDSD is literally bursting with features – such as Direct/Pre-Amp, 3.5mm input, SPDIF Input/Output and much, much more. You will have to see it to believe it.   Specifications:     Item Description Remarks Inputs/Outputs     Inputs (rear) USB 2.0 type A “OTG” Socket (with iPurifier® technology built-in) Compatible with computers (Apple/Win/Linux), iPhone, iPod Touch, iPad and Android Devices, camera kit or USB-OTG cable required.

8 legendary Class A mic preamps in the same class as the Focusrite ISA and RED ranges. They don't make them like this anymore... This unit is in very good condition - see pictures: front face is pristine with no scratches, only a few usage scratches around the rack ears from installation (marks will be hidden again after mounted onto a rack). It never left the studio. The Octopre provides eight pristine discrete channels of Focusrite Class A mic preamp and compression, OctoPre PLATINUM routes directly to any digital audio workstation via eight standard analogue outputs. Each channel features a revolutionary compressor/limiter circuit, providing a warm-sounding compressor, which morphs into a brick wall limiter to avoid those critical overs, ensuring total control over all eight channels. The mic preamps featured in OctoPre PLATINUM are similar to those featured in the award winning Focusrite Top-Of-The-Range. They are a transistor-based Class A design utilising the same full-bandwidth philosophy as the legendary RED and ISA mic preamps, ensuring detail and clarity without colouration. The first two 'super channels' also feature phase reverse, as well as TRS jack inputs on the front fascia for quick and easy, DI-free instrument plug-in. Eight line level balanced (+4 dBu) analogue inputs and outputs are provided as standard via 25-pin D-type connectors. These D-type connectors may be routed to 8 XLR/TRS by means of an (optional) 8-way 25-pin D-type to 8 XLR/TRS breakout cable, available separately. In addition to the analogue outputs, the OctoPre can be fitted with digital output (OPTIONAL CARD). Detailed description from the focusrite website: The OctoPre is an eight channel Class A microphone preamplifier, featuring a classic Focusrite mic pre and a revolutionary compressor/limiter circuit on each channel. The mic pres featured in the OctoPre are similar to those featured elsewhere in the award winning Focusrite Platinum range. They are a transistor-based Class A design utilising the same full bandwidth philosophy as the legendary Focusrite Red and ISA mic pres, ensuring detail and organic clarity without obvious colouration. The revolutionary compressor/limiter circuit provides each channel with warmsounding compression, which morphs into brick wall limiting to avoid critical ‘overs’ when recording digitally. The first two channels also feature phase reverse, as well as unbalanced 1/4” jack inputs on the front fascia for quick and easy, DI-free plug-in of guitars and basses. With Class A Focusrite analogue signal processing and comprehensive A/D interface options, OctoPre is the perfect partner for a Pro Tools™ system or any other digital audio workstation, making high quality, multi-channel recording easy. Equally, it could be utilised as part of a compact multi-channel location recording solution (with a laptop or ADAT™, for example), or as an additional set of professional-quality mic pres for any analogue or digital console or hard disk recorder. The original OctoPre is a typical Class A Platinum design, (based around a 737 Rhom transistor) and it is solid state, it has extended bandwidth (up to at least 180kHz at the top end) and sounds transparent. The original OctoPre has an edge in being more forgiving if you want to slam the pre's hard (but more 2nd order harmonic distortion as a result). -The Octopre has a dynamics (compressor/limiter) control on each channel -The Octopre has 48V phantom power switches on each channel -The Octopre has line in and out connections on 25 pin D-sub connectors and 8 XLR inputs for mics Performance specifications: THD:0.001% @ 20dBu input, mic and line at 0dB gain Noise:-96 dB at unity gain through the unit Mic EIN:-128 dBu @ 6dB of gain with 150Ω termination impedance Frequency response:-1 dB at 10 Hz to 200 kHz Carefully packed with powercord.
