TRUE Systems announces the introduction of our pT2-500D Precision Dynamic Preamp in the APITM 500 series module format. The pT2-500D preamp is optimized for dynamic and ribbon microphones, and also produces superior results with self-powered tube microphones. While similar to our TEC-nominated pT2-500, it provides more gain (76dB) and higher input impedance, along with a unique low frequency adjust control. The LO-F Adjust is a 6-position switch that provides nuanced low frequency contouring that can be particularly effective with vocals and bass DI applications. A discrete FET DI with In and Thru connections completes the package.


  •   APITM 500 series module format

  •   Detented, continuous Gain Control and Dual Gain Ranges for:

    • 76dB maximum gain

    • easy recall of gain settings

    • easy gain setting over wide gain ranges

  •   High Input Impedance for:

• More clarity and accuracy with ribbon and dynamic microphones

  •   Low Frequency Adjust Control for:

    • nuanced low frequency contouring

    • better definition of vocals and bass without boosting high midrange

    • elimination of low frequency “mud”

  •   “Real DI” with IN and THRU jacks for:

    • easy hookup to amps for simultaneous DI and amp’d tracking or live sound

    • easy hookup to other DI’s or effects for simultaneous tracking or live sound

  •   Totally Balanced Topology for:

    • insensitivity to ground noise/loops

    • Insensitivity to EMI, both external and from adjacent modules/power supplies

    • reduced distortion

  •   Rail-to-Rail design for:

    • higher internal headroom

    • higher maximum input level without pad

    • higher output level without transformer and excessive power supply current

  •   0.1% precision resistors for:

    • exceptional Common-Mode and Output Signal Balance performance

    • excellent unit-to-unit sonic consistency
