iPre System Notes

iPre System Notes

featuresHere's some more detail about our iPre multichannel preamp. Just compare the features below to any other product on the market. We think you'll agree that the iPre is somewhat special!

Remote Racks

  • The audio amplification and processing is done in modular remote 1RU racks.
  • These are air cooled (no fans, no noise) so can be kept in the same room as your other gear, or can be mounted in a machine room.
  • They can be swapped out rack by rack for maintenance

Power supply

  • The iPre is powered by our new digital power supply, which provides all of the internal console voltages from an external 12V DC supply
  • The external 12V supply is provided by us, and works all over the world, so there's no mains selection required
  • The external power supply is resistant to brown outs, so your console stays working without problems
  • The digital power supply was designed by us, and in conjunction with the linear regulators on each circuit provides noise free, responsive power to all the circuits
  • Our products now consume 30% less power and dissipate 30% less heat than before
  • All power status is shown on the individual rack front panels

Electronics

  • Noise performance at real levels. The circuits have been designed to give a low noise floor at all gain levels. People often talk about how quiet the iPre is, and this is why.
  • Wide frequency response. In order to get good HF distortion figures, you need a high frequency response. However too wide allows RFI to enter the pre. We use a wide frequency response, tailored by passive rolloff filters for RFI protection.
  • All signals remain balanced throughout the preamp: we never unbalance them
  • Digital signals are interfaced with digital transformers, followed by active buffers to minimise interference
  • A precision high power 48V supply provides power for even the most thirsty of microphones

Connectors

  • All audio outputs are connected by DB25 Tascam pinout Dsubs
  • We can provide XLR breakout panels, or discrete snakes to help you wire up
  • Alternatively, you can buy most of snakes you need from many different vendors

Expansion

  • The iPre is a modular based preamp. You can add extra features to your iPre at any time, so your studio is always capable of doing what you want.
  • Usually you can upgrade your iPre, without it having to be returned to Crookwood, saving you time and money.
