Data

General

  • Manufacturer: [ [KS]- "Kücke & Schmidt" - AudioTeam ]
  • Model: Active 3
  • Year of manufacture: 1984
  • Made in: Germany
  • Colour: oak, wenge, walnut natural, ash, cherry, mahogany, teak, walnut black, walnut white
  • Dimensions: 240 x 500 x 325 mm (W x H x D)
  • Weight: 16 kg
  • Original price approx.: 2800,- DM (UVP pair)


Connections

  • Number of inputs:
    • NF 2.1V/47 KOhm (at the power amplifier).
    • LS 2,1V/1 KOhm (at the preamplifier)
  • Number of outputs:
    • none


Technical Data

  • Type: 3-way compact speaker, closed, active.
  • Chassis:
    • Low frequency: 200 mm (coated membrane)

Midrange: 51 mm Supronyl dome tweeter Tweeter: 25 mm hardened aluminium dome with Supronyl single voltage Power amplifier: 240 Watt sine wave (IHF)

    • Low frequency: 80 Watt sine wave

Midrange: 80 Watt sine wave Tweeter: 80 Watt sine wave

  • Frequency response: 37 - 22,000 Hz ±3 dB.
  • Transitional ranges: (for multi-chassis LS).
  • Input sensitivity: 2.1V / 90dB / 1000Hz
  • Maximum power consumption : 360 Watt

Special Features

  • 3 built-in power amplifiers --> separately controlled chassis to increase dynamics and resolution.
  • Switchable bass attenuation at 38Hz : switch positions 0, 1 and 2 cause a bass level reduction of 0dB, 3dB or 6dB so that room adjustments can be realized.

Compatible with full and power amplifiers, as the 5-pin DIN socket has a contact which is connected via a series resistor. --> Pin.2 = [Ground] ; Pin.4 = [LS+]. --> With a "5Pol-Din to 2 times Cinch" adapter : black/white connection. (the preamplifier operation is done via the red side).

  • Intelligent automatic switch-on and switch-off --> The LS only switches on when the frequency mix is below 850Hz, not in case of mains crackling or other interfering signals. Automatic switch-off takes place after an 8-minute signal pause. In addition, the KS Aktiv 3 switches off to protect the drivers in the event of too high a level or voltage peaks and reactivates automatically after a few seconds.
  • discrete power amplifiers --> no power amplifier IC's

1% tolerance on metal film resistors; 5% tolerance on film capacitors of the crossovers.

The front of the LS is covered with a velvet-like flocking to avoid sound losses due to reflections and the resulting interference at the baffle.

Optional: A foot stand in matching style and wood finish to extend the placement possibilities of the "power dwarf" designed as a compact or shelf speaker.
