The D6 amplifier is a two channel power amplifier and controller unit. It is designed for use with the d&b fullrange loudspeakers (passive systems) and subwoofer systems.

A linear mode is available allowing the D6 to be used as a linear power amplifier.

The D6 Amplifier incorporates:

• universal voltage, switch mode power supply with active power factor correction (PFC)
• two channel Class D power amplifier
• digital signal processors (DSP)
• comprehensive protection circuits
• controls and indicators
• analog and digital signal inputs and link outputs
• REMOTE and SERVICE interface

The level control on the front panel incorporates a digital rotary encoder, which enables selection of all operating modes in conjunction with a Liquid Crystal Display (LCD).

User definable equalization and delay functions are incorporated in each channel of the D6. The 4-band parametric equalizer provides optional Boost/Cut or Notch filtering and the signal delay capability allows delay settings of up to 340 msec. (= 100 m / 328 ft) to be applied independently to either channel. A signal generator offering pink noise or sine wave program is also incorporated for test and alignment purposes. Each unit can be given a unique Device Name to simplify identification and a password protected LOCK function is also incorporated to inhibit unauthorized set up changes.

The D6 is housed in a 19" × 353mm (13.9") 2 rack unit enclosure made from steel.
