Spectral Audio Prototype Loudspeakers. Very rare loudspeakers prototype designed by Rick Fryer in the late 1990s for the American brand Spectral Audio. Apparently they had been made in collaboration with Focal, the famous french manufacturer with Christian Yvon help. This is the only known example. The filters are oversized. The speakers weigh almost 60 kg. They were expected to be sold for around 35000€.

EXTREMELY RARE prototype of one of the first Sonnetar by MS-Optics. The Sonnetar is a very fast lens (50mm f1.1) in a very compact format, often compared as a Micro Noctilux. This one is coming from a batch of less than 10 lenses that were originaly designed by Sadayasu Miyazaki. It comes in a full package with box, caps and every documents including hand notes from Sadayasu Miyazaki himself. I also give with the package an UVa II filter from LEICA. Everything is in mint condition; never used and stored in a very safe environment. I ship worldwide (for 100€) and in France (for free). We can also schedule a hand delivery if you are in Paris. Be carefull with taxes and duties from your country if you are outside the EU. Please note that the payment needs to be done by bank transfer and that I will send the package once I receive the transfer. Feel free to reach me for further information or if you have any questions.

ROLAND U-110 Midi PCM Sound Expander Vintage 80´s Sound  The U-110 is a basic rack-mount sound module consisting of acoustic-oriented PCM samples with preset settings, limited flexibility, and boring late eighties sounds. It's nothing to get excited about. It has 2MB of ROM-based sampled sounds, none of which sound great. The U-110 is fairly noisy as well. Its palette of sounds could be grossly expanded with up to four expansion cards, but good luck finding those today! The U-110's biggest distinction, really, is that it was Roland's first totally digital sample-based synth. At the time, that was a break-through - look at all the realistic sounds you get in a single rack space MIDI module! Nowadays, it's hard to wonder why anybody would want one of these. The U-110 was available in a prototype form as the T-110. But the U-110 was soon replaced by the U-20 keyboard and U-220 module. Astral Projection used a U-110 before they switched to the U-220. Polyphony - 31 voices (6-part multi-timbral) Oscillators - 2MB ROM samples, expandable to 4MB Multitimbral - 6 parts Filter - None Envelopes - Amp envelope attack/release can be edited, among the limited parameters. Effects - 2 FX - chorus and auto-pan. Memory - Expandable with PCM cards: Up to 4 cards can be used simultaneously. Keyboard - None Control - MIDI Date Produced - 1988 no PCM cards

USBMidiKliK3x3 / 3 MIDI IN X 3 MIDI OUT   - The KikGenLabs WARNING: THIS AUCTION IS FOR A PCB ONLY. NO COMPONENTS MOUNTED. This PCB is a prototype and is considered as "new" and is fully working. You must buy components yourself. An easy job. No surface components at all. See schematic at the Github project page:  https://github.com/TheKikGen/USBMidiKliK4x4 The USB MidiKlik 4x4 firmware allows the following features : - The board is USB Powered, so no additional power supply necessary. It works driverless as a class compliant device, with Windows XP SP3, Vista 32 and 64 Bit, Windows 7 / 8 / 10   32 and 64 Bit, and Mac OS X, Linux ALSA, Akai MPC Live/X/Force, IOS, Android.  - USB Powered, no additional power necessary - 4 USB IN / OUT - 3 MIDI IN / 3 MIDI OUT JACKS - Configuration with SYSEX and/or user menu from a terminal connected to the USB serial port - Support of very big SYSEX files transmission - Hardware reset remotely by Sysex  - Sysex to switch to configuration menu serial mode - Ability to change the USB device ProductStringName of the device, and also change the USB Vendor and Product Ids.  Changes persist after power off.  - STANDALONE Mode:  can be used as a standalone MIDI routing box without connecting any host - Stackable:  several interfaces can be used, to get 6x6, 9x9 MIDI ports,  without any conflicts as Name, VID & PID can be changed. - Complex routing rules configurables by sysex or from a user menu - Routing rules allow you to transform the USB MIDIKLIK into a MIDI MERGE or a MIDI THRU very easily. - Ability to route any USB IN to any USB OUT/ MIDI OUT (7 targets possible 4 USB, 3 Midi jack per board) - Midi messages filtering: channel voice, system common, realtime, sysex   The firmware is open source so you can adapt or modify it for you own needs. The project is active.

Ettus USRP B200 USB Software Defined Radio SDR. État : Occasion Overview The USRP B200 provides a fully integrated, single board, Universal Software Radio Peripheral platform with continuous frequency coverage from 70 MHz –6 GHz. Designed for low-cost experimentation, it combines a fully integrated direct conversion transceiver providing up to 56MHz of real-time bandwidth, an open and reprogrammable Spartan6 FPGA, and fast and convenient bus-powered SuperSpeed USB 3.0 connectivity. Full support for the UHD (USRP Hardware Driver) software allows you to immediately begin developing with GNU Radio, prototype your own GSM base station with OpenBTS, and seamlessly transition code from the B200 to higher performance, industry ready USRP platforms. An enclosure accessory kit allows users of green PCB devices (revision 6 or later) to assemble a protective steel case. Experimentation with Low-cost SDR Experiment with the USRP B200 across a wide range of applications including: FM and TV broadcast, cellular, GPS, WiFi, ISM, and more. Users can immediately begin prototyping in GNURadio and participate in the open-source SDR community. Full support by the USRP Hardware Driver™ (UHD) software allows seamless code reuse from existing designs, compatibility with open-source applications like HDSDR and OpenBTS, and an upgrade path to industry-ready USRP systems to meet application requirements.  Here are some examples of what you can do with a USRP B200: B200 System Architecture The integrated RF frontend on the USRP B200 is designed with the new Analog Devices AD9364, a single chip direct conversion transceiver and digital baseband processor, capable of streaming up to 56 MHz of real-time RF bandwidth. The B200 utilizes one signal chain of the AD9364 allowing it to be bus powered and reducing software and hardware design complexity. Onboard signal processing and control of the AD9364 is performed by a Spartan6 XC6SLX75 FPGA connected to a host PC using SuperSpeed USB 3.0. The USRP B200 real time system throughput is benchmarked at 61.44MS/s quadrature providing the full 56 MHz of instantaneous RF bandwidth to the host PC for additional processing using GNURadio SDR design environment. Features - The first fully integrated USRP device with continuous RF coverage from 70 MHz –6 GHz - Full duplex operation with up to 56 MHz of real time bandwidth (61.44MS/s quadrature) - Fast and convenient bus-powered connectivity using SuperSpeed USB 3.0 - GNURadio and OpenBTS support through the open-source USRP Hardware Driver™ (UHD) - Open and reconfigurable Spartan 6 XC6SLX75 FPGA with free Xilinx tools (for advanced users) - Early access prototyping platform for the Analog Devices AD9364 RFIC, a fully integrated direct conversion transceiver with mixed signal baseband - Steel enclosure accessory kit available for green PCB devices (revision 6 or later)
