METER CALIBRATION
METER CALIBRATION PROCEDURE
Metering of any input or output is provided by two twelve segment LED bargraphs, with VU
ballistics. The meter circuit features a peak-hold function, which makes it easier to see the
actual peak. The peak-hold function can be disabled by grounding pin 11 of U53 and U63
(LB1412) at P96. Refer to schematic MX52XX MASTER SECTION P/N 047696 sheet 4 of 4.
There is one calibration trim pot for each bargraph meter. The trim pots are accessible through
two holes located at the top of the meters. The factory setting is for 0 dBU = 0.775 VRMS.
Typical "0" meter levels:
0.775 Vrms (0 dBu) Factory setting (For most applications this is the desired calibration).
1.228 Vrms (+4 dBu) If mostly "Pro" equipment is connected to the mixer.
0.316 Vrms (-10 dBu) If mostly "consumer" or semi-pro equipment is connected to the mixer.
Inject a 1kHz sine wave at the desired RMS voltage level into the TAPE L, RCA (phono) jack.
Make sure none of the mixer's Solo switches are engaged.
Press the 2 TRACK PLAYBACK switch, located in the CONTROL ROOM section of the Master
module.
Adjust the trim pot so the first yellow segment of the meter just begins to turn on.
Repeat the above procedure for the right meter, using the TAPE R input.
IMPORTANT NOTE:
When using the meters in conjunction with the various Solo switches, the SOLO LEVEL
control must be turned up to maximum. This is the calibrated position to accurately
meter the solo bus level. If the SOLO LEVEL control is not at maximum, the meter
reading will be below the real output level of the soloed output.

BUS CONFIGURATION
AUXILIARY BUS PRE/POST CONFIGURATION
The standard factory MX-5200 Auxiliary Bus configuration is:
•Aux 1/3 routes the post-EQ/post-fader signal to Auxiliary Buses 1 or 3.
•Aux 2/4 routes the pre-EQ/pre-fader signal to Auxiliary Buses 2 or 4.
Internal jumpers allow this configuration to be changed to the following:
•Post-EQ/post-fader or post-EQ/pre-fader on all Aux sends (1 through 4).
•Pre-or post-fader on all Aux Sends (1 through 4).
In addition, when the channel MUTE switch is engaged, the post-EQ/post-fader signal is muted,
but the pre-EQ/pre-fader signal is not. This allows the channel to be "cued" in the PFL solo
system, even if the channel is muted.
MONITOR BUS PRE/POST CONFIGURATION
•Pre-EQ/pre-fader or post-EQ/post-fader to Monitor 1 and Monitor 2, switch-selectable.
Internal jumpers allow this configuration to be changed to the following:
•Post-EQ/pre-fader or post-EQ/post-fader signal to Monitor 1 and Monitor 2.
CHANGING THE PRE/POST CONFIGURATION
The pre/post jumpers are actually three adjacent solder pads. They are located directly next to
the MONITOR PRE/POST switches. The circuit board does not need to be removed from the
panel, as the pads are accessible from the solder side of the PC board. A small connecting
trace between two of the pads sets the factory jumper configuration. When changing the factory
configuration, the trace must be cut to break the existing connection. To connect the desired
pads, simply create a solder bridge across them. The jumpers are labeled (PX3,4,5), and the
square pad indicates the number one (1) pad. PX3 selects pre/post EQ and is always pre-fader.
PX4 selects between pre/post fader for AUX 2/4. PX5 selects pre/post fader for AUX 1/3. Refer
to the Input Channel schematic P/N 047688 sheet 1 of 2 for pin outs.
PANEL REMOVAL
Remove the top trim piece. The screws are located above the rear patch bay.
Remove the two (2) flathead screws at the top of the panel.
Slide the panel towards the patch bay until the lower edge of the panel exits the retaining slot.
Lift the panel straight up about 1 inch above the chassis.
Raise the bottom (Fader end) of the panel up to a near vertical position.
Gently rest the top edge of the panel onto the top of the chassis.
Use a support stick to hold up the panel similar to the hood of a automobile.
*****CAUTION*****
DO NOT RAISE OR LOWER THE BOTTOM OF THE PANEL WITHOUT HOLDING THE TOP
OF THE PANEL UP OFF OF THE CHASSIS. PIVOTING THE TOP OF THE PANEL AGAINST
THE CHASSIS WILL SEVERELY DAMAGE THE PC BOARD, TRIM POTS AND OTHER
COMPONENTS.
INTERCONNECTS
There are many ribbon cables (Cable Assemblies) used as interconnects between circuit
boards. The connection points are all labeled, i.e. P58 on the master board connects to P58A
on the master I/O board. Use caution when reconnecting the cables as it is easy to connect
them incorrectly (one pin off). On power supply interconnects, this can cause major damage to
various components.
Use caution!

THE FOLLOWING SECTION CONTAINS TWO DIFFERENT PARTS LISTS FOR THE PRINTED CIRCUIT
BOARD ASSEMBLY. THE "REV A" PARTS LIST REFERS TO THE REV A CIRCUIT BOARD. THE "REV B"
PARTS LIST REFERS TO THE REV B CIRCUIT BOARD. THE REVISION LEVEL IS LOCATED ON THE SOLDER
SIDE OF THE PCB, ADJACENT TO THE RAW BOARD PART NUMBER (047722 A) NEAR THE CORNER, BY
THE HEATSINK.
ANOTHER WAY TO IDENTIFY THE REVISION IS TO LOOK FOR THE THERMAL SWITCH LOCATED AT THE
CENTER OF THE HEATSINK. THERMAL SWITCH MISSING, REV A. THERMAL SWITCH PRESENT, REV B.
ENCLOSED ARE SCHEMATICS AND SERVICE DIAGRAMS FOR BOTH VERSIONS.
"A" REVISION BOARD USE: SCHEMATIC 047721 REV C.
