DIGITAL SECTION
-
Burr-Brown PCM1704 D-A converters operating at 96 KHz at all times
-
All inputs below 96 KHz are upsampled to 96 KHz before conversion
-
The upsampled output is clocked out via a Low Phase Noise/Low Jitter precision crystal oscillator to eliminate any interface jitter or timing problems with the incoming datastream
-
Multiple power supplies are used, with additional regulation and filtering located at all critical components
-
Differential Passive LC filtering is used on the voltage output of the DAC PCB
-
High Speed JFET Current to Voltage Conversion with differential output is used to drive the Passive LC Filter
-
It will wash your car, clean your windows, make coffee and sound good all at the same time...

REMOTE CONTROL RANGE MEASUREMENTS
If the remote is closer than 9 feet, the maximum angle response is around 60 to 75 degrees which is the counter sink angle of the receiver's hole in the front panel. Measurements done with new set of batteries.
-
Distance of 9-10 ft, the maximum angle is 65-75 degrees.
-
Distance of 12 ft, the maximum angle is 60 degrees.
-
Distance of 13 ft, the maximum angle is 45-55 degrees.
-
Distance of 16 ft, the maximum angle is 45 degrees.
-
Distance of 20 ft, the maximum angle is 25-35 degrees.
-
Distance of 25-27 ft, the maximum angle is 0-15 degrees. This is the maximum distance-angle the remote will do.
