(1) AP (Audio precision)
(2) Dual track Oscillograph
(3) DMM
2. Set up
(1) AP output: 0dBu 1KHz SINE(sine wave), load out 600Ω Bal-Float.
(2) AP input: Load 100KΩ BNC-Unbal. BW: 22Hz~22KHz. Fltr: A-weighting(12017)
3. Visual check
Inspect the appearance of PBM4. Ensure it is ok; the knob of the potentiometer should be no friction.
4. Test function
(1) Test the Phantom power
The power indicator lights up when you switch on PBM4. Set PHANTOM power switch to ON position.
The black pen of DMM connect to the first hole of MIC jack and respectively test CH1~CH4 of MIC
jack with DMM. The red pen of DMM respectively test the second hole and the third hole, the voltage
is 15V±2V. Set the switch to OFF position after finishing testing.
(2) Set PBM4
Turn all knobs to the middle position and turn all LEVEL knobs correspond to CH1~CH4 to the
maximum. Turn off DSP, the MAIN OUT indicator lights up when the AP signal input from LINE IN jack
of each channel; Set the AP output balanced when you test.
(3) Test DF/FX knobs for the output signal(CH1~CH4), MONITOR knobs and MAIN LEVEL
A. Set LEVEL knobs of CH1~CH4 to the maximum.
MAIN OUT: 3dBu(±3dBu), distortion <0.05%. Adjusting LEVEL knob, the output should be
changed accordingly.
MONTOR OUT LEFT: 8dBu(±3dBu), distortion <0.05%. Adjusting MONITOR knob, the output
should be changed accordingly.
FX SEND: 3dBu(±3dBu), distortion <0.003%. Adjusting DSF/FX knob of each channel, the
output should be changed accordingly

(6) Test the indicator of output level for MAIN OUT
Set the level of output signal for AP TO 10dBu. Connect the signal input of AP with MAIN OUT.
Set MAIN LEVEL from the minimum to the maximum. Inspect the output level on the computer during test,
the level that displays on the indicator of unit is in accordance with the level that displays on the computer.
The error is ±2dBu, the indicators light up in sequence from low to high. Don’t make mistake.
(7) Test the function of PAD switch, MIC jack, DSP switch, FOOT SW and DSP.
Page 21
A. Input the signal of 1KHz,-20dBu from MIC jack with Balanced. Output level data is similar to
20
LINE IN input .
B. When press the DSP switch, MUTE CHIP lamp should be up or down. Connect FOOT switch.
MUTE CHIP should be up or down.
C. DSP is switched on when the red lamp is down.
D. Adjust AUX/DFX RET knob to the minimum and adjust PRESETS switch. The wave on the
oscillograph stays the same.
(8) Test the EQ of CH1~CH4
A. Respectively Input signal 0dBu, 1KHz to LINE IN of CH1~CH4, adjust LEVEL of corresponding
channel to make MAIN OUT is 0dBu.Turn the EQ of HIGH and LOW for corresponding channel to the
middle position. Scan the curve of FREQUENCY RESPONSE. Refer to the yellow curve for the result.
B. Turn the HIGH EQ knob of corresponding channel clockwise to the maximum and turn the LOW
EQ knob counterclockwise to the minimum. Scan the curve of FREQUENCY RESPONSE, refer to the
purple curve for the result.
C. Turn the HIGH EQ knob of corresponding channel counterclockwise to the minimum and turn the
LOW EQ knob clockwise to the maximum. Scan the curve of FREQUENCY RESPONSE, refer to the
red curve for the result.
For the test above, the error of the curve range is ±3dBu.
Page 22
Turn the EQ knob of all channels to the middle position after finishing test.
21
(9) Test the curve of MAIN EQ
A. Respectively input signal 0dBu, 1KHz to a channel from CH1~CH4. Set all slide potentiometers
of MAIN EQ to the middle position. Adjust LEVEL of the corresponding channel to make MAIN ON is
0dBu. Connect the input terminal of AP to MAIN OUT LEFT and MAIN OUT RIGHT. Scan the curve of
FREQUENCY RESPONSE, refer to the yellow curve for the result.
B. Set the slide potentiometer 63, 400, 2.5K, 16K to the top
Set the slide potentiometer 160, 1K, 6, 3K to the bottom.
Scan the curve of FREQUENCY RESPONSE, refer to the red curve for the result.
C. Set the slide potentiometer 63, 400, 2.5K, 16K to the top.
Set the slide potentiometer 160, 1K, 6, 3K to the bottom.
Scan the curve of FREQUENCY RESPONSE, refer to the red curve for the result.
D. For the test above, the error of the curve range is ±3dBu.
Turn the EQ of all channels to the middle position after finishing test.
(10) Test listening
Respectively input the music signal of proper level to all signal input terminals. Connect the unit
output with power amplifier and connect MONIOR OUT with headphone. Set all potentiometers related
to this channel from the minimum to the maximum when you test the input and output of each channel,
Page 23
repeat twice or thrice, eliminate unwanted noise during test and the output should be changed
22
accordingly. Turn on/off the switch twice, it should be no noise.
Company preset: Turn all LEVEL knobs to the minimum. Set the PHANTOM switch to OFF position and
other knobs to the middle position.
