DETAILED SPECIFICATION FOR RECEIVER AVR7000 (120V)
PARAMETERS
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
Nominal input level : 200mV for general purpose inputs
Power figures should be kept minimum 10min., between 15 and 35
o
C
.
Terminator : 1kohm for general purpose inputs
All Voltage Measurements are made with RMS detector, unless otherwise specified.
Filter : IHF-A filter
R/O = Rated Output, which is 100 W into 8 ohm resistive load, for both Stereo and 6 CH DIRECT inputs.
UUT= Unit Under Test.
Power supply : 120 V , 60 Hz
