2-8 Meter LED
When the MAIN OUT and MONITOR OUT output levels are as shown in the table below, the corresponding
METER LED lights up.

2-9 Distortion
Set each volume control of the INPUT section and MASTER section to nominal for the systems shown in Tables 1,
2 and 3. When each output except the REC OUT level reaches +14 dBs, the distortion ratio should be less than
0.1 % from 20 Hz to 20 kHz.
2-10 Maximum Output Level
In the states of 2-9, the maximum output levels of MAIN OUT, MONITOR OUT and EFFECT OUT should be
+20 dBs with a distortion of less than 1%.
2-11 Equivalent Input Noise
The measurement CH level volume is assumed to be at maximum, and the other CH level volumes are assumed to be at
minimum in the states of 2-3.
When the Lo-z and MIC input terminals are connected with a 150 ohms resistor, the MAIN OUT terminal noise level
should be less than -61 dBs. If the noise level does not reach -61 dBs due to a gain variance, the converted noise level (=
noise level minus the actual gain of the channel) should be less than -124 dBs. (Apply a DIN-AUDIO filter.)
2-12 Residual Noise
Set all the input level controls at minimum in the states of 2-3. When the MASTER and EFFECT OUT level
controls in the MAIN and MONITOR section are changed to maximum or minimum, the residual noise should be
as shown in the table below. (Apply a DIN-AUDIO filter.)

2-13 Phantom Power (+48 V)
Connect a load resistance of 10 K ohm (more than 1W) between pins 1 and 2 of both the Lo-z IN and the MIC IN
input terminals, then short between pins 2 and 3 of the Lo-z IN and the MIC IN input terminal.
When the PHANTOM switch is turned on, +35 ± 3 V should be obtained between the load resistance.
2-14 Digital Effect
When the DIGITAL EFFECT ON switch is turned on, the ON LED lights up. When the DIGITAL EFFECT ON
switch is turn off, the ON LED light goes out.
When the DIGITAL EFFECT ON switch is turned on while inputting a sine wave of -60 dB to the CH1 Lo-z IN
at a minimum MONITOR level control setting, the signal level of the MONITOR OUT will be more than -25 dBs.
Even if the SELECT switch is changed to VOCAL, L HALL and S HALL, confirm that the output level is even.
Confirm that the output soundfrom the vocals musics souce has a digital effect, and confirm that the effect is able
to be turned on and off by the FOOT SW.
2-15 Stability
When a capacitor of 10 FP to 0.1 F is connected in parallel to the loading resistor at each SPEAKER OUT
terminal, or when all VR and EQ control volumes are set to MAX , there should be no abnormality; for example,
there should be no oscillation. Especially, do not oscillate if the FREQ LEVEL is at maximum.
