Eight IN & Eight OUT

Eight channel balanced input to unbalanced output and unbalanced output to balanced output cards with gain matching.

Eight In & Eight Out are high performance, flexible gain circuit cards for use in console rebuilding projects. Applications would include: adding balanced inputs and outputs to consoles whose native I/O is unbalanced, balancing patchbay insert points or bringing semi-pro output levels up to usable pro levels.

Overview

  • Eight IN:
    • Eight electronically balanced inputs.
    • Eight unbalanced outputs.
    • Gain structure is set during assembly, common configurations would be +4dBu input to -2dBu output or +4dBu input to -10dBu output. Other configurations are available, including different gains for each channel.
  • Eight OUT:
    • Eight unbalanced inputs.
    • Eight electronically balanced outputs.
    • Gain structure and input impedance is set during assembly, common configurations would be 10k input impedance, -2dBu input to +4dBu output or -10dBu input to +4dBu output. Other configurations are available, including different setups for each channel. Maximum recommended gain for this stage is about 20dB.
    • Gain will automatically compensate for balanced or unbalanced outputs (as with a transformer).
  • Inputs and outputs are on standard pinout db-25's for easy interfacing.
