Harman Kardon DPR 1001 - Rear Panel Connections Overview; Rear Panel Input and Output Jacks (Part 1); Rear Panel Input and Output Jacks (Part 2)

B) DIGITAL INPUT, BASELINE AUDIO PARAMETERS(STEREOSURROUNDMODE)
Measuring methods are based on IHF and IEC standard 268-3
Measurement conditions,unless otherwise noted :
Output resistive load =
(8) ohms
/ All channels loaded.
Tone Off or Tone(Bass,Treble), Balance, EQ control : Center Position , Other SW's : OFF, Volume:Max
All Voltage Measurements are made with RMS detector, unless otherwise specified.
Filter :IHF-A filter
R/O = Rated Output, which is 50 W into 8 ohm resistive load, for PCM Digital inputs.
UUT= Unit Under Test.
All measurements are made in Stereo mode, at FL and FR Speaker Output jacks, unless otherwise noted.
Power supply : 120 V , 60 Hz

Gain Difference between
Analog and Digital Input
Coaxial 1
With a 0 dBFS, 1 KHz PCM bitstream, and Main Volume at 20 dB
below Max, the Output Voltage at FL and FR speaker outputs
should bethe sameas when,applyinga 2 Volt, 1 KHz sinewave
amplitude into an analog Stereo Input. Read the dB difference
between

Coaxial 1
With a 0 dBFS, 1 KHz sinewave PCM bitstream,and Main Volume
at 20 dB belowMax, set meter to read THD+N Ampl, with dBr
units. Use 'A Weighting' filter, 10 Hz-80 KHz BW. Record the
Output Voltage at FL and FR speaker outputs to be the 0 dBr

Coaxial 1
With Digital Generator amplitude at -999 dBFS (Generator turned
off), 1 KHz sinewavePCM bitstream, and Main Volumeat 20 dB
belowMax, set meter to read Amplitude,10 Hz-22 KHz BW. Take
Amplitude readings on both FL and FR Speaker Outputs.
