ON,PFL,1-2,3-4 switch:
When setting EFFECT RTN fader and VR to MAX and each switch(ON,PFL,1-2,3-4) to ON,the output level shall be within
the range specified the Table 4.16-1.
It is specification although the level is changed when setting of HALL 2.

Feed no signal and set the CH EFFECT level control to MIN and PROGRAM select switch to 3(HALL 3).
The noise level of "ST OUT L/R" shall be less than -50dBu.
1: Check all about the case of 1 to 16 PROGRAMS.
Feed music source and check the DIGITAL EFFECT by listening to it.

4.17 Stability

Shunt the output terminal with the capacitance of 10pF-0.1microF respectively. Then, the unit shall not oscillate.
Shunt the all input terminals with 150 ohms, and set the all VR and EQ Control to MAX.
Then, the unit shall not oscillate.

4.18 Primary Voltage Tolerance

The unit shall work normally with the primary voltage of ± 10%.
