Driver amplifier lab instrument features front-panel control
Boulder, Colo. Picosecond Pulse Labs (PSPL) has introduced the Model 8001 LABware instrument that integrates a 12 Gbits/s amplifier, a power supply, amplitude control, and crossing point control in a single instrument.Get more news about Amplifier Front Panel,you can vist our website!
The Model 8001 provides a typical amplitude of 8 Vpp and a rise time of 14 picoseconds. Each control is separately adjusted through dials on the front panel. The lab instrument may be used for driving Lithium Niobate optical modulators up to 12.5 Gbits/s in the lab or used as a linear amplifier with 12 GHz of bandwidth when the instrument's input is kept below its saturation level.
Talk to audiophiles that grew up through the 1990s and the chances are they associate brands such as Sony, Yamaha, Onkyo, Pioneer and Denon with meaty AV receivers and, possibly, mini systems. The reason is that it was around this time that the major Japanese corporations began directing their energies into developing products for the burgeoning home cinema market, meaning these younger hi-fi enthusiasts never really saw them flex their design muscles in the stereo arena.
However, that is changing. Pioneer, Onkyo and Denon all now offer high quality two-channel equipment once more, while the Technics brand has returned with a vengeance after being mothballed by parent Panasonic. Now Yamaha has thrown its hat into the ring once again with the expansion of its 5000 series, the NS-5000 loudspeakers [HFN Jun '17] being joined by the GT-5000 turntable, along with the C-5000 preamplifier and M-5000 power amplifier under test here, both of which retail at £6499 apiece.
Retro Reborn
When it comes to cosmetics, the C-5000 and M-5000 continue the traditions rekindled by the A-S2000 amplifier [HFN Mar '08]. This means piano-style keys for power and feature selection, solid metal bars for knobs on the input selectors, a chunky volume control and those glorious analogue meters on the power amplifier. These, in turn, hark back to past Yamaha designs, yet somehow the two manage to look stylishly modern at the same time.
Both units sport gloss piano black side cheeks and the colour options for the 6mm-thick top plate and 9mm-thick front panel are silver or black. Of course, retro styling has its own appeal, but technology has moved on. Fortunately, the feature list and internal design of both the C-5000 and M-5000 are formidable. This is a genuine back-to-basics enterprise that builds on the performance of the earlier range-topping A-S3000 integrated [HFN Nov '13] and provides a high-end flagship to sail at the head of Yamaha's very new A-S1200, A-S2200 and A-S3200 integrated amps.
Looking at the C-5000 preamp first, this tips the scales at over 19kg and, at 435x142x451mm (whd), is larger than many an integrated amp. It's analogue-only, so those hoping for DACs or streaming facilities will be disappointed. But this means that the money has gone where it matters – on wringing the very last ounce of performance from whatever analogue source you care to plug into it.
