2.2.2 Frequency characteristics

Using 1 kHz as a standard for the output voltage, the output voltage shall be within -0.5

kHz, -10 B dBu sine waves are input to the input terminal.

2.2.3 Total harmonic distortion ratio characteristics

The total harmonic distortion ration shall be 1 % or less when a 1 kHz high definition sine wave is input to the input terminal and the

output voltage of 36.4 dBu has been attained. This inspection shall be completed within 30 seconds.

2.2.4 Output noise level

Measure the noise level at both terminals of the load resistance when the input attenuator has been set to MAX and the input

terminal has been grounded by the introduction of a 600

MIN and measure. It shall be -60 dBu or less.

Process after completion of inspection

Close up the input attenuator in a half-clockwise direction.

Set YAMAHA SPEAKER PROCESSING to on.

Set the mode switch to STEREO.

Others

A DIN audio filter shall be used for the measurement of the noise level.

resistance. It shall be -60 dBu or less. Next, set the input attenuator to

0.5 dB at 20 kHz when 20 Hz, 1 kHz, 20
