EMX66M

 INSPECTIONS

0.

PREPARATION

(1) Mesuring instruments

•

 Oscillator (Ballance output type, Output impedance 150

Ω

)

•

 Oscilloscope (Input impedance 100k

Ω

)

•

 Level meter (Input impedance 100k

Ω

)

•

 Distortion Meter

(2) Notes for mesuring

•

 Noise level must be mesured by using DIN AUDIO FILTER.

•

 0dB is equal to 0.775V.

1.

Power Indicator Check

Confirm that the power indicator LED lights up while the power is ON.

2.

Mixer Check

2.1

Preparation

•

Except otherwise indicated, input signal should be 1kHz sine curve and output impedance of signal source should be 150

Ω

.

•

Connect the load of 10k

Ω

 to MAIN OUT, MONITOR OUT, EFFECT OUT and REC OUT terminal.
