2. D6 Amplifier
Fig. 2: D6 Amplifier
2.1. D6 based systems
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 ms (= 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" x 351 mm (13.8") 2 rack unit enclosure made
from steel.
